[Story between me and Sharp]
In 2008, this is my second year from school (student) to school (teacher). Because I often require accommodation on duty to manage students, and I have a soft spot for SONY PS3 , So I plan to choose a small size 1080P TV as a game partner. Ten years ago, the 32-inch 1080P TV was an extremely high-end existence. We finally picked a Sharp 32GE5A (32-inch) in Jinhua Suning. At that time, a 50-inch TV was available for a price of 6999, but the pursuit of high-end According to the principle, I bit my teeth and bought it. It was one of the few 32-inch Full HD TVs at the time. What’s more dramatic is that Suning Sharp’s sales 8 years ago have now become my cousin (actually my wife’s cousin, I just called along)... So let me know The brand for high-end TV is Sharp.
On March 15, 2013, I married my wife. The choice of TV in the new house has become a big problem for our family. As a cousin who used to sell at Sharp, because he knows a lot of "insiders" in the TV industry, he strongly recommends Sharp TV to us. Thinking that the Sharp 32GE5A that accompanied me for 8 years has not been broken, the excellent quality really made me have a strong feeling for the brand, so I bought the Sharp X850A and the master bedroom with a price of 2W in my living room. The 3,000-yuan 40LX450A...So, the brand that brought me into Internet TV is Sharp.
In 2016, Sharp 32GE5A, Sharp X850A and 40LX450A served in my house for many years, and they have never been broken or repaired. Sometimes people are so weird. When a brand starts to build trust, it becomes a "giant" in my mind. Perhaps it is because my story has attracted the attention of Sina event parties, or because there is a faint "matchmaking" between Sharp and my wife. This time I am honored to have the opportunity to experience Sharp LCD-50TX55A, so I The brand that brought into the 4K world is Sharp again!
[Sharp LCD-50TX55A's unpacking and installation experience]
was worried about such a huge amount at first, including whether I would ask me to pick up the goods by SF. The facts are satisfying. It turns out that SF has a master who specializes in delivering bulk goods. Hey hey he moved from the 1st floor to the 5th floor. I felt so excited and handed a cigarette to the master. I am again impressed by the strength of SF Express. I like Wang Wei more and more! ! !
Sharp LCD-50TX55A currently has no relevant product information on the official website of Sharp in China, but the Internet platform has already begun to sell. I personally estimate that it should be a model specifically for Internet platform sales. The label shows that this product has passed China's energy efficiency labeling level 3 standards, and it seems that it performs well in terms of energy saving. In fact, for home appliances such as TVs that do not need to operate 24 hours a day, Level 3 energy efficiency will not bring much burden to home users. Instead, products such as air conditioners, refrigerators or routers need more attention.
The gross weight of this product is 19KG. It is difficult to unpack it by one person. If you plan to make the wall hanging, you must have two people to complete it. There are not many items in the box, but they are all practical. In addition to the Sharp LCD-50TX55A body, base, remote control, and manual warranty card, two additional AAA batteries (Panasonic) are also provided. All of them are available, so just assemble the base and it's OK. As for wall mounts, in fact, most brands of TVs will have to pay extra for wall mounts when they buy them, and Sharp is no exception. The structure of the
base looks very simple, but the all-metal base is full of materials, want to bend it? dream! The installation of
base is very simple, each base only needs 2 screws to be firmly fixed.
This is the underside of Sharp LCD-50TX55A. There is a long row of holes. I have seen some online reviews saying that this is a heat dissipation hole? In fact, this is its speaker! Regarding its sound performance, I will describe in detail below. First release two keywords: DTS+Dolby!
please
Sharp LCD-50TX55AAfter installation, the ultra-narrow frame looks very atmospheric!
Input picture description
The measurements of Sharp LCD-50TX55A are 1250*203*780, and the minimum diagonal size of the visible image is 126CM. This is a 50-inch 4K smart TV.
such a large-size home appliance is really not good for shooting in my small home.......
finally found a suitable location to shoot Sharp LCD-50TX55A, can you see how I shoot from the screen.......
According to the text description known by Baidu: 4K resolution means that the pixel value of each line in the horizontal direction reaches or close to 4096. In most cases, it specifically refers to the resolution of 4096*2160. Depending on the scope of use, 4K resolution also has a variety of derivative resolutions, such as Full Aperture 4K's 4096*3112, Academy 4K's 3656*2664, and UHDTV standard 3840*2160, etc., all belong to 4K resolution. category.
is strange to say. It may have been influenced by the Sharp brand for a long time. I especially like this brand, because every time I see the word "SHARP", my mind jumps out of the idiom...
Today's TV sets are embarrassed to sell if the speakers do not have a little technological content. Dolby sound, DTS sound, HDMI, these are all technologies that have to pay copyright fees!
Is Sharp LCD-50TX55A thin? This is hard to tell, because the picture below... But what does it have to do with being thin at home and not thin? ? The thinnest part of
looks like this, which is thinner than a dime silver coin, about one-third the thickness of this silver coin (9.9 mm).
The back of Sharp LCD-50TX55A is very simple, the power cord is designed on the left side, and there are 2 straps that can be used to bundle some cables such as HDMI, video and audio. The input and output interfaces are all designed on the right and right sides of the TV. The design is more centralized and management is more convenient.
In this "small box" there are: digital audio output, service dedicated terminal, component/composite video input and Internet port.
is at the bottom right corner of the back of the main unit. This is a five-dimensional navigation switch. It can be turned on by pressing it once, and it will be turned off by long pressing for about 3 seconds. Flicking left and right is to adjust the TV volume. It can fluctuate up and down without any function. The system has not yet given undefined functions for its up and down toggle? This is the only switch of Sharp LCD-50TX55A, which also means that if your remote control is out of power, the TV will not work! But I came up with a new method, which is to install "Wukong Remote Control" or "Ali TV Assistant" on the TV, so that users can directly operate the Sharp LCD-50TX55A with their mobile phones. ! ! ! But having said that, I am still looking forward to the next firmware update, some basic operation functions can be applied to this five-dimensional navigation key, so as not to waste the "five-dimensional" function.
is on the left side of the TV. Here are some commonly used ports: 2 USB ports, 3 HDMI ports, 1 SD card slot and 1 antenna port. Although the number of these ports is small, they can basically meet the needs of ordinary households. At this point, it is time to give Sharp LCD-50TX55A a bit of a thorn. I found that its USB port is not very good for supporting USB flash drives. When accessing the USB flash drive, occasionally a long black screen will appear, although the number of occurrences Not much, but I always feel that it’s not so cool to use...The other thing is that these two USB ports do not support USB3.1 mobile hard drives, such as the Samsung T3 solid state mobile hard drive in my hand. . TV products are different from mobile phones and tablets. Its update speed is very slow for families. Although the USB port usage rate on the TV is generally not high, it is compatible.There should be the most basic guarantee.
Here is the heat dissipation holes on the back of Sharp LCD-50TX55A. You can see that these heat dissipation holes run through the cross section of the TV. The huge heat dissipation holes are very effective for the heat dissipation of the TV. I did not use an infrared thermometer to It is tested, because I have been running for 4 hours and it feels cold...so the temperature test is unnecessary~.
Today’s smart TVs are pretty stingy on the remote control. The simple design can’t make me interested in using it.....My X850A is also a smart TV. So big? ! It is true that this must be determined by the market positioning of the product! But the good news is that this simple remote control is relatively easy to use. It feels good when you press the buttons. There will be no click-and-click noises like cheap remote controls. It takes a little bit of effort to press down. The feel is basically qualified. The
remote control has a black matte texture on the front, and a smooth ergonomic design on the back. It is very comfortable to hold. Compared with those flat and flat remote controls, picking up the Sharp LCD-50TX55A remote control is simply one Kind of enjoyment.
Many remote controllers will choose to use button batteries for power supply. This not only increases the replacement cost for users, but also is not satisfactory from the environmental protection level. The remote control of Sharp LCD-50TX55A uses AAA batteries, and users can choose to use rechargeable batteries to power it, which is environmentally friendly and reduces replacement costs. This design is great!
After talking about the appearance of the product for most of the day, I can finally talk about the content of Sharp LCD-50TX55A! Power on, the huge scarlet SHARP is brought into view, full of domineering!
do some simple settings, you can enter the system.
My personal habit of using smart products is that I don’t hesitate to see if there is any system upgrade when I get a new product. Regardless of the three or seven twenty-one, it will be better to upgrade the system and then experience the product. What is depressing is that Sharp LCD-50TX55A does not have a system update reminder function like Sharp's high-end TV, but requires users to enter the system for manual operation, but the online system update is very foolish, just follow the instructions step by step. Now, this has left a good impression on me.
[Sharp LCD-50TX55A screen test]
People often say that buying a TV is equivalent to buying a screen. It can be said that the value of a TV is mainly reflected in the screen. I believe Sharp users know that their family has a "four-color technology", and all TVs equipped with this technology are the most high-end TV products in the Sharp family. However, Sharp LCD-50TX55A does not have such technology. Could it be said that Sharp LCD-50TX55A without four-color technology has no bright spots? After my experience, I found that this is obviously not the case! Even a little surprise! So next I used the screen test tool in Dangbei assistant to test Sharp LCD-50TX55A. The first test of
is the light leakage performance under the full black screen state. The Sharp LCD-50TX55A screen can see a little light leakage when the screen is full black, especially at the top and bottom right corner of the screen. It is more obvious, but it is good The light leakage is not serious and is within the acceptable range. When the
screen is in the full white state, the screen seen at this time is quite uniform, and there is no color block or uneven light.
Sharp LCD-50TX55A is very good for the restoration of green, red and blue colors, without any color cast, and the screen brightness is uniform, and there will be no color deviation. You can see the three pictures below. There seems to be on the left and right sides. The dark side is actually caused by the camera shooting, and the naked eye cannot see such a dark side.
In the color transition test, the edge between different color transitions can be seen with the naked eye with extremely slight vertical stripes, which shows that the Sharp LCD-50TX55A is in colorExcessive performance is good.
In the definition test, thanks to the 3840*2160 high resolution of Sharp LCD-50TX55A, each line of text appears clear and sharp, without any burrs.
In the black and white grayscale test, the visibility of the first grid is the lowest. In addition, the other 38 black and white grids can clearly distinguish the density of black and white, indicating the gray of Sharp LCD-50TX55A The order performance is very good. In the afterimage test of
, the naked eye can't feel any jitter or afterimage at the edge of the color block. Originally, I was most worried about the performance of Sharp LCD-50TX55A in afterimage. It seems that the big rock in my heart can finally fall!
final screen evaluation score: 96 points, looks very good!
[Screen showdown between Sharp LCD-50TX55A and Sharp X850A]
believes that what everyone wants to know most is the high-end TV in the past: What is the difference between the screens of Sharp X850A and Sharp LCD-50TX55A? ! Here I will satisfy everyone’s wishes~SO, the showdown between four-color technology and non-four-color technology is about to kick off... In the next test, I used a USB flash drive to copy some static pictures and then used Sharp LCD -50TX55A and Sharp X850A are directly read and compared. It is worth mentioning that after the USB flash drive is inserted into the Sharp LCD-50TX55A, the system will immediately prompt that there is an external device. The user can directly watch the contents of the USB flash drive without entering the deep multimedia function, which is really convenient!
Please input
Sharp "four-color technology" (Gui Li Taki) popularization: On July 20, 2010, Sharp held a technology conference in China and released a Sharp's exclusive LCD panel technology-four-color technology. Four-color technology has completely overturned the display method of red, green, and blue that has been used since the birth of color TV to express colors. Through the combination of four-color panel technology and TV loop technology, a wide color gamut of high-quality images has been achieved Modification and high-definition also contribute to a substantial reduction in energy consumption. With the advent of Quattron (four-color technology), colors that are difficult to accurately depict with ordinary three primary colors can be accurately represented. This is a half-century history of TV innovation. In the real world of nature, yellow and cyan are the most common colors, but in the past, televisions could not truly reproduce these "regular" colors. The way to improve color saturation is to increase the brightness of the backlight and the transmittance of liquid crystals, and improve the color expression of today's LCD TVs. The "four-color technology" adds yellow to the sub-pixels of the liquid crystal panel to achieve the performance of the yellow color gamut. Significant improvement, overcoming the lack of color reproduction capabilities that existed before. At the same time, under the same power conditions, the four-color technology achieves a brighter white, which is about 20% higher than the three primary colors. Due to the addition of one sub-pixel, the total number of sub-pixels in the entire panel has increased from 6.22 million to 8.29 million. As a result, viewing the same image, the "four-color technology" screen will be more refined and delicate. This technology is Sharp's exclusive patented technology! (The text is taken from Baidu Encyclopedia)

First of all, let’s look at a set of pictures of beauties that you like to hear. You can see that Sharp LCD-50TX55A's treatment of skin color is neutral tones, which looks very cold or warm. It is comfortable, especially when it is used to reflect the skin of girls. The fair skin and the cheeky face really want me to climb up and take a bite... The four-color technology of
Sharp X850A turns the girl's skin into a warm color. In fact, this is the real skin color of Asians (yellow races). It seems that Sharp X850A is more natural for the processing of skin color.
resolution, after all, the Sharp X850A was launched earlier, with a resolution of only 1920*1080, so the picture definition cannot be compared with the Sharp LCD-50TX55A with 4K resolution. The level of delicacy is almost a level!
zIn the comparison of 2z
anime pictures, the color of Sharp LCD-50TX55A is still neutral, the color of the characters is clear and natural, and the black background has a slight whitening phenomenon.
Please
Sharp X850 is still warm to the color expression of anime characters. Although the photo looks a little reddish, it is not so exaggerated when viewed with the naked eye. On the black background, the light leakage control is obviously better than Sharp LCD-50TX55A.
input picture description
The clarity of the two TVs does not seem to need to be described, I believe you can see the difference at a glance.
This is a photo of me...I am making waves on the beach...From this picture, we can see that Sharp LCD-50TX55A has a fairly positive response to the blue sky. This has been obtained in the previous theoretical test-blue test After verification, all colors are natural and there is no color cast.
So I continued to make waves in the Sharp X850A.....At this time, the color of the whole photo became a lot warmer, the sky was a little purple, and the skin color was reddish. Continue to explain: this is caused by the camera shooting, and the naked eye The observed Sharp LCD-50TX55A screen is not so warm.
Please do not explain the resolution of the two TVs
, just take a look.
Enter the picture description
and continue to expose yourself. This is one of my wedding photos....This is a photo that has been graded by a colorist. From this photo, it can be seen that the difference between the two TVs is not very big, especially the skin color of the characters is almost the same. The main difference is still reflected in the train and the sky, which is still a neutral and a warmer tone. What is the explanation for the resolution of
? See for yourself...
Let's take a screen shot of a map of China, this is a 4K high-definition photo I found from the Internet! Sharp LCD-50TX55A is a little bit cyanish at this time? Actually, the background color is quite white when viewed with the naked eye!
Sharp X850A is still the same, warmer, and the red color deviation is still caused by the camera! But this kind of warmer tone is not suitable for expressing this kind of too serious picture...
If your eyes can't see the difference in the above several resolution pictures, I believe the picture below should reflect very clearly, right? ! Sharp LCD-50TX55A can still clearly reflect extremely small text, while Sharp X850A is probably going crazy...
After comparing Sharp LCD-50TX55A and Sharp X850A, I can clearly feel the difference between the two TVs. Sharp LCD-50TX55A color performance is very pertinent, not cold or warm, the biggest advantage of 4K extremely high resolution is that it can present extremely sharp pictures, in photography jargon, this is called high sharpness. The color of Sharp X850A is warm, it looks very warm, the color reproduction is better, and the reproduction of black is more accurate, but the disadvantage is that the 1920*1080 resolution brings less picture detail. In terms of the sharpness of the whole picture, there is no advantage compared to Sharp LCD-50TX55A. Here comes the question and conclusion: Since the two TVs represent the typical high-end and low-end products, and each has advantages and disadvantages, does the Sharp high-end TV with four-color technology seem to have no price-performance ratio at all? No, no, after three years of my experience with the Sharp X850A TV, I think four-color technology will have more advantages in expressing film colors, because the film color itself is warmer, and watching movies with Sharp X850A is simply It feels like sitting at home and watching a movie. Although it is not as sharp as a 4K TV in terms of edge sharpness, it is actually not as grainy when viewed with the naked eye. In addition, there is another obvious difference, which is the smear of the moving picture.The phenomenon also shows a more obvious gap between the two TVs. Sharp LCD-50TX55A can feel a slight smear of characters when watching a football game, while on the Sharp X850A, there is no trace of smear. It directly affects the clarity of the entire dynamic picture, so Sharp's four-color technology is still the black technology at the top of the pyramid in the TV industry.
[Appreciation of 4K video screenshots]
I am very satisfied with the color reproduction of Sharp LCD-50TX55A mentioned above. The color tone is more pertinent, so it can be used to display static pictures or dynamic videos without bias. , So I will use the screenshot of the 4K video to show everyone.
Note: All the pictures in this article, except for the out-of-the-box photos, have not been post-production. Shooting tool: Canon 6D, lens: Tamron 38 1.8, automatic shooting.
It is worth mentioning that the Sharp LCD-50TX55A is perfectly compatible with H.264 4K video files, audio and video are synchronized, and silky smooth.
[]
HD video capture 4K video resources for real, in fact, the network is not very much for the average user, is mainly intended to use Sharp LCD-50TX55A to watch high-definition video on the network, so these videos are not possible Just like those 4K videos above, it is perfect without black edges. Since the video resolution cannot reach 4K, how do these high-definition resources perform on the Sharp LCD-50TX55A? Through these screen shots, we can see that Sharp LCD-50TX55A is still very comfortable in expressing high-definition video. Thanks to the resource integration and cooperation between Sharp and Youku, Tudou, Wasu and Ali Entertainment, the video quality provided by Sharp LCD-50TX55A is quite high. !
Please enter the picture
While watching the movie, here is the way to mention the performance of Sharp LCD-50TX55A. Sharp LCD-50TX55A's speakers are designed at the bottom of the main unit, and a whole row of long sound holes appear to be domineering. Although this position is not directly facing the user, it still sounds transparent. Thanks to the support of DTS and Dolby sound effects, the overall sound resolution of Sharp LCD-50TX55A is very high, and the sound field performance in vertical and horizontal directions is good, but the disadvantage is the lack of sound layering, or the sound is a bit thin The low frequency is also stretched, so it is slightly insufficient for the performance of the big scenes in the movie, but because its sound tends to be balanced, it is a good choice to listen to music, such as When playing the "Xiami Music" recommended by the System Application Center, the 10W output power of Sharp LCD-50TX55A is huge, even if it is turned on to the loudest, there will be no breaks in the sound, closing the eyes and even feeling like listening to the box.
Description
[Sharp LCD-50TX55A's system features and human-computer interaction performance]
Sharp LCD-50TX55A's UI system is called "Smart UI", based on Android 4.4 deep customization, because Sharp LCD-50TX55A has a built-in dual-core processor , The memory is 1GB, and the storage capacity is 8GB. This configuration is the same as other TVs, and it is not comparable to mobile phone hardware. So in terms of fluency, I think it can only be regarded as good, and occasionally there will be screen jams., But fortunately, the probability of such a stuck screen is not high, and it is only the most commonly used for users to watch videos, so such smoothness is not a weakness for ordinary users.
For licenses, Sharp LCD-50TX55A cooperates with Wasu TV. The resources are integrated video resources of Youku, Tudou, Wasu and Alibaba Entertainment. It has absolute strength in video content and video quality.
hits 30,000+ hours, cinema blockbuster 9800+ hours (in-depth cooperation with Universal/Warner/Lionsgate/Paramount/Sony), 5800+ hours of children’s content, 4K HD zone, hilarious variety shows, documentary library Wait a minute, various types of video resources are rich and colorful, allowing you to stay at home and see the old days... The content distribution of
Sharp LCD-50TX55A is not much different from similar products. It is mainly divided into movies, TV series, variety shows, children, 4K membership exclusive, shopping, applications and other content. There are many sub-projects under each big section, which is very rich in content. All resources are available in high-definition/ultra-definition versions. When the broadband environment is sufficiently matched, Sharp LCD-50TX55A will automatically adjust to the clearest resource presentation. This ability can be described as full of humanity.
as shown in the figure below. For example, when entering the movie area, the first thing that catches your eyes is the current main movie. Users can quickly enter the resource to watch. In addition, a richer content option is also designed under the movie. Popular recommendations, updates this week, special agent movies, member theaters, Douban high scores, etc. have everything, and the content is extremely colorful.
When I enter a certain movie resource, what attracts me the most is the preview function in the small window. The content of the video resource will be automatically played here, and the display is intuitive and clear. At the same time, there are detailed video resources such as the leading actor, director, release time, and film overview. Content, users can first understand some basic content of the video and then choose whether to watch it. At the same time, the right side of the preview window will automatically select a batch of videos that you may be more interested in for recommendation based on the user's daily selection of video resources. I personally like this functional layout and design, which eliminates the need for step by step. The trouble of inquiries, film selection has become a kind of enjoyment!
I have experienced many TV box products. Although some TV boxes provide a 4K area, they are a bit stretched in terms of resource abundance. The 4K area of Sharp LCD-50TX55A is extremely rich in terms of the number of movies. Not only that, its 4K resources are not only limited to movies, but also involved in TV series, variety shows, documentaries, etc., although these 4K movies are not It is not 4K in the true sense, but their black edges are narrower, the bit rate is higher, and the picture clarity is improved.
Any video resource platform will never forget the membership benefits, and Sharp LCD-50TX55A is no exception! If you become a member, you can realize exclusive resources such as multi-screen sharing, massive film library, 4K HD full free, and free of ads. But... the price of this member seems a bit high! But if you purchase Sharp LCD-50TX55A now, you can get a full year's membership! ! !
integrates the shopping function into a smart TV. This is the first time I have seen the shopping function of Sharp LCD-50TX55A is cooperating with Tmall. Personally, I feel that it is better to use a mobile phone or PC to go to Tmall.. ....
[Setting Interface Analysis]
Sharp LCD-50TX55A's setting interface is designed very simple, it is mainly composed of basic settings, image settings, audio settings, channel selection settings, network settings, application management, presentation and system 8 functions. Among the basic settings, I think the most eye-catching feature is the quick start function. When the quick start is not turned on, the Sharp LCD-50TX55A has a boot time of 32 seconds.When Quick Start is turned on, its startup time is shortened to 7 seconds. (I personally test)
In terms of color adjustment, Sharp LCD-50TX55A is much richer than similar products on the market. In the setting menu, you can not only see the brightness, contrast, color temperature and other items, but also adjust the backlight and GAMMA value. For advanced setting items that are only available on the display, users can adjust the pleasing picture style according to their own preferences.
In terms of audio settings, Sharp LCD-50TX55A is also very rich, with adjustable treble and bass, adjustable balance, and adjustable surround sound, which is also quite rare in similar products. However, I personally feel that it would be better if I could hear the adjusted effect while adjusting. In the
network setting interface, you can set up for wired or wireless networks, and the settings are extremely simple. The
application management is mainly for the management of TV memory and external storage devices. It is not used much at ordinary times. However, it is better to enter the settings for new TVs. For example, after allowing unknown sources to be turned on, you can install unofficial apps.
In the system settings, I think the most commonly used is the network upgrade function, yes, Sharp LCD-50TX55A supports online upgrade system! However, the TV does not take the initiative to provide a message to update the system, but requires the user to manually enter the page to find out whether there is a new system update. Wouldn't it be better if it could actively prompt?
