This problem has been lingering in the author’s mind for a long time. As the representative of technical schools in China TV brands, Hisense has always been active in the forefront of cutting-edge display technology, but its attitude towards OLED has been unusually calm. At this technical achievement conference, Hisense told the story:
"In fact, as early as 2010, Hisense obtained an OLED-related invention patent, and the research and development of OLED technology has never stopped in the past 10 years. When the production capacity, technology and market become mature, Hisense officially entered the OLED TV industry. A cautious attitude is a mature brand that should be considered. It can be said that Hisense has never rejected OLED, but is patiently waiting for the maturity of the opportunity. Just today, Hisense announced that it will fully promote OLED! "
The launch of OLED TV is the result of Hisense’s careful consideration (the picture shows Hisense’s first OLED TV A8).
"Hisense brings more than just a similar OLED panel."
As the top TV brand in China, Hisense will do its best to build the first OLED TV. From the information gained at this conference, we are also very surprised to see that Hisense has brought the "six-fold afterimage protection technology" to improve the previous OLED problems. It can be said that Hisense has completely "matured" the OLED display technology by its own efforts.
Hisense’s technological innovation thoroughly ripens OLED technology.
Then, what is the performance of Hisense’s first OLED TV, which has high hopes, is slowly revealed for you:
As the "number one player" of China color TV, Hisense has chosen to enter the field of OLED TV, so it is bound to have strict quality requirements for the first OLED product. We have tested Hisense’s flagship products many times before, and their products have a very good performance in color saturation, contrast, brightness and mature technology. It is believed that Hisense, which has been deeply involved in the TV industry for decades, can polish an OLED TV with excellent picture quality.
It has six color adjustment modes and more precise adjustments in image quality.
Hisense A8 has many different color adjustment modes, which users can adjust according to different content requirements. At the same time, in the advanced image setting, the adjustable image quality parameters are very comprehensive, including advanced image parameters such as motion image quality compensation, image noise reduction, brightness dynamic range, gamma, color temperature, white balance, brightness mode, dynamic highlight range, etc. We are surprised by the degree of accurate and controllable image quality.
Entering the objective test, we first use Spyder 5 Elite to test the accuracy of color reproduction of Hisense A8 TV:
Test instrument: Spyder 5 Elite
Spyder 5 Elite
Measured results of color gamut value
Hisense A8 TV Gamut Value
The NTSC color gamut value of Hisense OLED TV A8 is 91% measured by Spyder 5 Elite. After comparing the performance of mainstream OLED TV products, we think that the color gamut value of Hisense A8 is excellent, achieving a very high NTSC color gamut coverage.
Note: The color gamut value represents the ability of the TV panel to display the number of colors. As for the evaluation of TV image quality, we think that the color gamut value is only suitable for reference, and the final image quality level needs to be evaluated in combination with the actual output effect of the image quality processing chip after optimization.
Measured results of color accuracy
Hisense A8 TV Color Accuracy
The color accuracy test result Delta E of Hisense A8 is 4.08, which shows that this TV product can display the original color of the picture with high accuracy. Considering the standard value of "what you see is what you get" of the display device, the color reproduction level of Hisense A8 is quite excellent.
Screen brightness/chroma uniformity
Brightness Uniformity Test of Hisense A8 TV
Brightness uniformity is a numerical value that describes the balance of brightness in different areas of the screen. In the test of Hisense OLED TV A8, we get the biggest brightness difference of 11%, which is close to the performance of professional desktop display. For Hisense A8, a 65-inch large-screen TV product, it is really commendable to have this brightness uniformity performance.
Note: In the test results of brightness uniformity, the greater the maximum value, the greater the difference between the brightness performance of this area and other areas, and the brightness difference that can be recognized by the naked eye will appear in the actual viewing process of users.
Color Uniformity of Hisense A8 TV
Color uniformity is a numerical value that describes the balance of colors in different areas of the screen. In the test results of Hisense OLED TV A8, the Delta E value of only one region is 2.9, and the Delta E values of other regions are less than 2. For this result, we can evaluate the color uniformity performance of Hisense A8 as excellent, and there is almost no difference in the color performance of each region. Similarly, compared with the performance of professional desktop display products, Hisense A8′ s performance is not inferior.
Note: the test result of color uniformity can be understood as whether the color performance is consistent in all areas of the screen.

In October last year, we organized six high-end OLED TV cross-reviews. Judging from the results of this objective instrument’s image quality test on Hisense A8 TV, the comprehensive image quality performance of Hisense A8 can stand firmly at the head of the cross-review, and it is rare to have such outstanding performance.
Static pictures are very suitable for showing the layering, detail and color accuracy of the picture. I was shocked after measuring a few pictures. There is really no one in this picture quality.
The red color is bright and rich, and the color transition is smooth and soft, which is close to the performance of the original film
The contrast between light and dark is very strong. Who else has such a high OLED brightness?
The color adjustment is not over-saturated, especially that steak, which looks real.
The color accuracy is high, the details of the wall are handled in place, and the bumps are even three-dimensional.
The first picture is bright and rich in red, with smooth and natural color transition; The second picture is very testing. Some TVs even show only black and white, but this TV shows a smooth and natural transition, and details can be seen in the black field near the edge. The good brightness performance is not common in OLED TVs, and there are indeed two brushes. The color performance of the third picture and the fourth picture is quite good, with high color accuracy and outstanding details. Judging from the test performance of the above four pictures, Hisense A8 is characterized by its accuracy of color performance and control of picture details.
There is no doubt that Hisense ULED technology has the ability to control and adjust light and shadow, and its flagship LCD product can even surpass Sony, which is known as the master of light and shadow, in brightness. This time, what we expected happened. Hisense applied ULED image partition technology, which has been deeply cultivated for many years, to this OLED product, which can theoretically improve the brightness and detail performance of OLED TV. So what will the actual performance be? I was really shocked.
The dark field is deep, and the dark details are perfect (ordinary TV can’t see the seams on the ground at all)
The texture details and color processing of fish are very good and distinct.
It can be clearly seen without magnification, and the extremely fine details of the face are perfectly displayed.
Dynamic clarity is greatly improved, and fast-moving objects have no obvious sense of blur.
Through the actual test of UHD video, it is obvious that Hisense A8 TV is excellent in detail control and light and shadow control. Relying on the advantages of OLED, black is deep; The application of ULED image partition technology is the killer of this TV: its dark details are perfect, and the nuances that we were difficult to find before can be shown in this TV. The improvement of contrast gives this TV more details and distinct levels.
OLED TV can bring the purest black performance by virtue of its self-luminous characteristics. For HDR(High-Dynamic Range- High Dynamic Range) TV, the most straightforward explanation is that HDR technology can make black deeper without losing dark details. In terms of brightness, it can be improved to a more realistic brightness performance, further enhancing the picture contrast and expanding the color display, which will bring shocking visual impact. However, HDR technology is not as simple as everyone thinks, nor can any TV play the role of HDR. How well does Hisense A8 TV control HDR? One word: truth.
The color of each stripe is very accurate, and the high brightness does not dilute the color of the picture.
The light and shadow are true, the dark details are obvious, and the fine print on the dashboard is also very clear.
The improvement of contrast makes the whole picture look more stereoscopic, and the performance of halo is very real.
The local brightness of the lamp is more obvious in the pure black picture.
The HDR video test makes Hisense, blessed by OLED, give full play to its advantages in light and shadow control. Under high brightness, it gives this OLED TV better details, and the dark details, layering, color performance and authenticity can all be effectively improved. Hisense A8 really didn’t let us down.
Visual angle real shot
In addition, I want to say that the visual angle is a factor that cannot be ignored. From different perspectives, the brightness and color expression level of Hisense A8 are almost the same, and there is no obvious attenuation, which reflects the good visual angle performance of Hisense A8.

The weakness of OLED TV lies in the lack of brightness, while the excessive brightness of LCD TV will dilute the color performance of the picture. The image quality performance of Hisense A8 TV surprised us. It skillfully applied ULED image partition technology to OLED products, giving full play to the advantages of Hisense TV in light control technology for many years. With the blessing of high brightness, the potential of OLED has been further explored, and the image quality performance can be comparable to the world’s top level, which is very remarkable.
Hisense A8 TV (65-inch version) relies on the special properties of OLED panel and adds Suface Sound Pro professional screen sound field technology. Compared with traditional speakers or speakers, it directly drives the OLED screen to vibrate, and makes sound by vibrating the air. In short, the whole screen is a speaker. Sound comes from the front and can be emitted at any point, so that the displayed image and sound can be perfectly integrated, achieving "sound and picture homology", and its stereo sound effect and telepresence experience can present a higher level.
In the actual experience, the sound can come from our front pavement, and because of the full-screen vibration, the sound will change with the position of the speaker in the picture, just like the surround sound experience. And the sound has a sense of orientation, and the picture and sound are completely synchronized. Make the trigger sources of vision and hearing achieve unprecedented unity, and truly realize the "integration of sound and picture". There is no doubt about black technology.
The sound effect setting has also been made great efforts, adding Dolby panoramic sound effect and more sound effect settings.
In addition to the sound on the screen, Hisense A8 has really worked hard on sound effects. It also adds Dolby panoramic sound effect, which breaks the traditional concept of sound channel but Dolby panoramic sound three-dimensional sound field. The sound appearance position and motion trajectory cooperate with the screen sound, which can be displayed on the screen and finally presented on TV. To put it bluntly, the combination of Hisense’s excellent pictures and excellent sounds brings us a more immersive and real audio-visual experience.
Actually, it’s not up to me whether it looks good or not, but the industrial design of this product is excellent if it is made of solid materials and meets the trend design concept. A8 TV continues Hisense’s always elegant and atmospheric design language, and the materials used are more refined and polished. The addition of minimalist aesthetics makes it look luxurious but smart.

On the whole, Hisense A8 has a perfect and balanced appearance design, and the polishing and fineness of details have even improved compared with previous products. Based on its own characteristics, OLED makes the appearance of this TV more in line with our aesthetics. At the same time, the low-key color scheme makes the TV more restrained but luxurious, and when placed in the living room, it presents a natural and harmonious aesthetic feeling. In addition, Hisense reduced the bottom Logo and moved it to the lower left corner, bid farewell to the complicated design, and left the front visual focus entirely to the screen.
Hisense has always been in the leading position in the field of smart TV control system. Hisense A8 has been upgraded to VIDAA AI system based on deep optimization of Android 8.0 system. Not only is the interface beautiful, but the control experience and AI intelligent experience are also leveraged. Hisense A8 can realize full-scene voice interaction. Not only search movies and TV series, book takeout, book air tickets, book hotels, visit Taobao, check traffic, check weather … anything. The main performance of the upgrade is that it has joined the far-field voice control, and the TV can act as an intelligent sound after the screen, and can wake up the TV at any time without using the remote control. To this end, we specially recorded a small video to see its performance.

After practical testing, Hisense A8 is really strong. We can realize "second response" to our questions, quickly identify and push out the content, and respond very quickly when adding more deep semantics, such as "fast forward to 25 minutes and 30 seconds", "fast back for 3 minutes" and "speak louder". Besides, this TV can do some seemingly impossible things. It can quickly identify people, buildings, landscapes and so on in the picture. When asked "Who is this?", the images in the screen can be accurately captured and identified, and the details of the actors and even the same clothes and equipment can be recommended.
Hisense applies ULED image partition technology to this product, which has reached the top level in terms of black grade, brightness and contrast, near-perfect detail performance and first-class image processing ability, and can better realize the strong contrast between the layering of the picture and light and shadow, and realize transparent and bright highlights or deep and pure black. In addition, Hisense A8′ s soft services such as system UI and AI intelligent control have reached the leading level in the industry, which is more suitable for Chinese people’s usage habits than joint venture brands in terms of humanization.
Hisense A8 TV is the first product that Hisense entered the OLED TV market. We can see Hisense’s persistence and breakthrough in the highest picture quality. Combined with the results of the cross-evaluation of six OLED TVs organized by Zhongguancun Online in October last year, we believe that the product strength of Hisense’s first OLED TV A8 is at the top of the OLED TV market, and Hisense’s years of technical accumulation in the display industry has been fully reflected in Hisense A8.
