Sharp "Black Technology" Drives: Comparison between 8K TV and 4K TV

The development and application of science and technology in the field of television far exceeds that of other home appliances, and the iteration time of television continues to shorten. TV types range from black-and-white TVs to color TVs, CRT TVs to LCD TVs, and display resolutions from 480P to 1080P. When we haven't fully realized that 4K TVs will dominate, 8K-definition TVs are already coming.

"The father of LCD TVs," Sharp launched the 8K resolution LCD-80XU35A called "black technology". What kind of experience is 8K resolution TV? The comparison may be more intuitive.

High-definition, small-size, non-meaningless, large-size, standard

Sharp 8K TV does not have the same type of products as the other TV series. It has 32 inches to 85 inches to meet various needs. The 8K TV has 80-inch and 70-inch models. Mainly because the 8K resolution display is extremely clear, but the small and medium size can not display its effect, so the current 4K TV is also the smallest 48 inches, is the same design concept.


Sharp 8K TV LCD-80XU35A appearance can be described as "big", 80-inch screen area plus the height of the base, the TV as a whole almost the same height, ultra-narrow design of the body also makes the screen look bigger .




Since the 80-inch TV itself is heavy, it is destined to be placed on the TV cabinet and requires a more solid base to support it. So this TV uses a sturdy steel triangular base, front for beautiful and translucent brown acrylic panels to do decoration and support, but its role is not limited to transformation.


Sharp's 8K TV's sound system is located on its lower frame. This arc-shaped structure base form can also allow sound effects to spread better and improve the sound and picture experience.


Interfaces, this TV provides three sets of HDMI interface, to meet the set-top boxes, game consoles, and other playback devices connected at the same time, and other traditional interfaces including USB interface, color interface, AV interfaces are also available.

Contrast test: 4K TV was secondarily slagged 1080P has been completely ignored

Sharp 8K TV LCD-80XU35A is most concerned about the sharpness of the resolution, while the resolution response is in use with higher resolution. The number of pixels is a factor of the clarity of the television, and it is more important to feel the brightness of the brightness information. The human eye is highly sensitive to colors such as green or yellow. This Sharp LCD-80XU35A adds yellow subpixels to the traditional three primary colors (red, green and blue) to achieve two brightness information in green and yellow in one pixel, horizontally. The sharpness is increased by 2 times. At the same time, the upper and lower parts of a sub-pixel are driven separately, achieving two brightness information in the vertical direction, and the clarity is increased by 2 times. In order to achieve 8K high-definition image display.

The following figure shows the pixels of a Sharp 4K TV and the pixels of an 8K TV in almost the same area.

Judging whether a TV reaches 2K, 4K or higher resolution, on the one hand, it can be judged by professional test charts, whether it can be displayed in point-to-point mode with different resolutions, and on the other hand, it requires the professional testing agencies. Professional equipment to judge.

First, the test was conducted using specific 8K and 4K test patterns. This test chart examines the effect of peer-to-peer tests and the detailed performance of the text, and only reflects the sharpness of performance, regardless of other display performance.


The following figure compares 4K TV and 8K TV, respectively, to show the performance of different TVs on the same test chart.

From the comparison of the first two test charts, it can be seen that in the same test chart with four test lines, the 8K TV can clearly show that there is no adhesion between the four lines, and that the 4K TV is stuck and can only see two lines and cannot be true. Restore the test chart.
From the comparison of the following two test charts, for the same letters, 8K TV can accurately display "of white kid" and other characters, but the letters on the 4K TV appear obvious jagged features, some letters can not distinguish between .

Through the above test chart, it is found that the 8K TV can restore the original appearance of the picture more accurately. This is the same for the picture display. The higher the resolution, the clearer the TV picture, and the clearer the picture is, the higher the degree of reduction is. The more accurately we can represent the real world, this is why humans have been working hard to increase the resolution of display devices.

Photo test: skin pores clearly visible beauty loss effect

After seeing the cold test chart, let's take a look at the performance of the 8K TV's ultra-high-pixel "beauty" photos. The first picture below is a complete display of the 8K TV to the photo, the second picture is a real shot of the face, and the third picture is a real shot of the eye.


Figure 1

From the TV screen shot (Figure 1), sharp 8K TV resolution is very high, and it is excellent for flower details and face restoration. From the last two close-ups, the details of the 8K TV can be seen more clearly.


Figure II

Taking close-ups of people's faces can tell that the facial expressions, which only occupy 1/36 of the screen area, are still exquisite, and not only the details of the petals are clearly visible, but also the texture on the human skin and facial freckles can be seen.


Figure 3

In the close-up view of the eye, which occupies less than 1/72 of the entire screen, the skin texture of the double eyelids of the character can be clearly seen, and no adhesion occurs in each lash.

The 8K TV's display of details has reached a point where it is almost "perverted."


The 8K TV was also sent to the China Electronics Standardization Institute Saixi Laboratory for testing. The test report showed that the Sharp LCD-80XU35A was certified by the agency to pass the 8K resolution test and reached the 8K resolution level.


8K display also has an intelligent experience to continue the "sandwich" interface design

Sharp 8K TV LCD-80XU35A uses Android 4.4.3 version of the smart operating system, providing 4GB of storage space, and the menu interface follows the previous "sandwich" menu with Lenovo, divided into three main interface live TV, Internet video and APP applications The user can perform "page turning" manipulation through the somatosensory remote controller.


This time, Sharp cooperated with licensee BesTV in Internet video, provided exclusive video resources such as Hollywood, TVB, SBS, and starry sky in VOD video on demand system. The United States discover/history/BBC documentary program in the United Kingdom. And the biggest difference between this system and other on-demand systems is that more "editing recommended" elements, from the original pure machine recommended video to many video editors, from the perspective of the audience for TV users to recommend "thematic video", but also fill in many Interesting recommendation reason.


In terms of App applications, Sharp TV introduced "Le Store", providing hundreds of App applications developed for large-screen smart TVs, suitable for large screen resolutions and operating habits, increasing the "playability" of smart TVs. ".


In addition, several categories of recommendations, rankings, special topics, games, education, applications, and personal centers are also provided in the “Le Store”, providing hundreds of applications. Moreover, these applications are applications that have been developed for large-screen TVs in the second place, and they have higher resolution and fluency than direct porting of smartphone apps.

Someone has to do something that others seem "useless"

Speaking of 8K, it is always said that "1080P has not been implemented yet, what 4K/8K is said to be useless." Indeed, now it is useless to look at 8K definition TV because there is no 8K source. However, what seems useless and forward-looking now cannot be done?

Let's talk about the TV ring. When the LCD came out, there were a lot of technical shortcomings. It was completely impossible to compare with the “Trinity” CRT at that time. At that time, the LCD was useless, but where? Let’s talk about the car. When the car just appeared, its speed was not as fast as the carriage. It was also more horses than the horse needed. The car at that time was also useless, but where?

Although the actual application capability of 8K TV is still very weak, it represents the continuous pursuit of the human spirit for visual exploration and represents the future that display technology can touch. Therefore, 8K is not meaningless.

Some people talk about "feelings," and others are sneakied. Some people are searching for limits and others are sitting on the sky. Maybe change the world, really need some "boring" people to do some "useless" thing.
