Open a certain sound and a book, the pure skin polishing filter makes people feel bored; press the TV remote control, the Abao color filter and the Morandi filter of the film and television drama are superimposed to the character distortion, and the people who see it are all good.
We resent the filters on the screen because the distorted picture makes people feel suspended and easy to visually fatigue.
The overwhelming "late period of five cents" made us begin to pay attention to the truth and texture of the picture presentation, and began to hope that the skin texture and imperfections of the characters in the blockbuster could be truly and completely presented, and the natural scenery colors such as flowers and trees could be restored to the greatest extent...
If you want to get the "real" in the screen, you can't do without the concept of color accuracy.
So how exactly does color accuracy help present this "real"? Today, let's use a TV - Skyworth S82 to explain it for you.
With the continuous improvement of the production specifications of film and television works, its quality requirements for display terminal equipment are also getting higher and higher. Among the many parameters, the color-related parameters of the display device, such as color gamut, color depth, etc. have been improving, but in contrast, the color accuracy has been intentionally or unintentionally "ignored" by the industry, which is a bit "relegated to the second line".
However, the importance of color accuracy is in the forefront, because the color accuracy of a display device is good enough to make the exquisite picture quality performance such as high definition, high color gamut, and high contrast give full play to the greatest advantages, and accurately restore the high-quality image content at the production end.
So how should this parameter of TV be viewed? How important is it?
1. Test the TV first to see accurately
△ E chromatic difference value is an international standard proposed by the CIE International Lighting Committee, where delta means "difference", and this E is the meaning of "feeling" of Empfindung, indicating the difference in feeling. △ The larger the E number, the more off-color, and the smaller the number, the more accurate the color. On the same device, the △E value measured by different colors will also be different, so we need to pay special attention to the average △E of a display device (the average of all the color difference values measured by *).
*△E and △E00 are chromatic difference values derived from different calculation formulas
The average △ E of Skyworth S82 is 0.86, and the color accuracy performance is comparable to that of professional film and television production monitors, which is a ceiling level in the TV industry!
But paper data is so good, is it really necessary for mass consumer products such as television?
After all, in the eyes of many people, office equipment such as monitors need to be accurate in color, and TVs only need to make the color conform to the consistent cognition of the human eye, that is, to please the human eye without obvious color casts.
2. What is the significance of beautiful parameters?
Ji Guojun believes that there are three necessities for the existence of tv high color accuracy:
First of all, this is in line with the audience's sensory needs are becoming more and more "keen" trend, overwhelming screen science, so that many people hold a "I may not be able to use, but good functions you have to have" mentality to look at the screen device, resulting in the public users on the real display of the requirements are getting higher and higher, so that high color accuracy has become just needed.
Secondly, this is in line with the development trend of the production side, and the emergence of high-quality works such as high-quality AAA games and movie blockbusters has made the high color accuracy of TELEVISION more and more important. Although many TV devices can also meet the general viewing needs, in order to enjoy the best viewing and gaming experience, to meet the needs of the public who want to see a better picture, it is necessary to be a color accuracy leader such as S82.
In addition, this is also in line with the hardware development trend of multi-screen devices, and the circulation between mobile phones, tablets and TV devices is getting better and better, and many flagship game device monitors/mainstream flagship mobile phones also pay attention to color accuracy performance. Therefore, as an important large screen in the living room, the TV also needs to achieve high color accuracy performance. The color accuracy is not good, and it is easy to feel uncomfortable when switching screens, of course, this also puts forward certain requirements for the color performance of other devices.
Therefore, it can be said that the color accuracy performance of Skyworth S82 not only achieves a professional level on paper data, but also has a very important significance and value for ordinary people.
As for what exactly does △E 0.86 bring to you? Ji Guojun next takes you through still images and dynamic videos to feel a wave:
In the eyes of the jiguojun at the scene, the colors of oranges and leaves are bright, there are fresh and delicate colors of plants, and there is a kind of naked eye look at orange trees. The restoration of color is very precise, there is no problem that some TV colors are too bright and the plastic taste is too heavy;
On the basis of restoring the original color, the picture quality adjustment is also very good, the colorful flowers in the picture are highly saturated, full of delicacy, while the bright and dark details of the petals and flower buds are rich, and the texture details are preserved, so it looks real and comfortable.
In the following natural landscape image, whether it is the gorgeous sunset by the reed lake, or a corner of weeds, pavilion lotus covers, S82 with high-color quasi-screens are quite in place, so that Jiguojun has a kind of "cloud sightseeing" foot.~
3. High score TV, what else can you see fresh?
In fact, many times, the camera as the input, although the brand model is different, basically can complete the task of "collecting color", the natural light signal is smoothly converted into an electrical signal, but this is only the first link; whether these electrical signals can once again be transmitted to the eyes of each audience in the form of light is the focus!
This means testing the accuracy of television displays, especially displays.
Thanks to Skyworth 30+ image quality tuning, Skyworth S82 achieves high color accuracy as a display device, but this does not mean that it has completely passed the test. Because there is another important parameter that also affects the accuracy of the TV display, that is, the color gamut.
The color gamut coverage of the display device affects the richness of its color display, and the wider the color gamut, the richer the color it can display.
Therefore, for tv, the color gamut coverage should first be broad enough, we used the test hardware to investigate the color gamut coverage of skyworth S82, and its performance was quite excellent, achieving 100% DCI-P3 color gamut coverage.
But is that enough? In fact, it is not, "color gamut adaptation" is also very important, it is also closely related to color accuracy.
The color gamut parameter standard BT.709 of 1080p TV programs and the mainstream color standard DCI-P3 of digital movie playback devices are basically the mainstream color gamut of consumer video that we can see on TV.
The difference between the two is that the P3 gamut is about 25% larger than the BT.709 gamut.
Looking at the contents of BT.709 on a DCI-P3 gamut screen, you may feel that the picture is a little oversaturated and too colorful; conversely, with a piece of BT. 709 Look at the content of P3, there will be a feeling that the picture is too gray and too dark.
*Narrow color gamut (left) contrasts with wide gamut (right).
Therefore, the TV color display to be accurate, to accurately restore the original color of different formats of film and television content, it is necessary to have the ability to convert the color space, Skyworth S82 at the same time to achieve the color space conversion between BT.709 and DCI-P3 color gamut, can fully meet the needs of more refined and demanding movies.
It can adapt to film and television works of different color formats, and maximize the texture of real scenes in TV and movie content.
In general, as a must-see parameter to buy a TV, color accuracy is very important, it is done well or not, and whether you can see a real enough picture on a TV is closely related, Skyworth S82 this round is through the double test of hardware + naked eye, color accuracy is fully passed, the color gamut coverage is complete enough, but also added the color space conversion function, can almost "perfectly" reproduce the blockbuster scene.
When we talk about picture quality, what exactly are we talking about?
Many times, when we mention picture quality, it is easy to evaluate according to personal feelings and likes, and picture quality seems to have become something that is inexplicable. But through professional testing and analysis, we can capture the "essence" of image quality, which encompasses multiple dimensions of TV display, including not only color accuracy.
Brightness, contrast, color depth, viewing angle, etc. are also very important, how this part of the parameters perform, when families buy a TV, they can get it by playing some static test charts!
It can be seen that Skyworth S82 is still in place in the color field, and the colors with high saturation of red, green, yellow and blue are displayed very brightly;
*The blue in the picture is the blue blue, there will be no green tone
* Orange flowers have saturation in place
* Different shades of color blocks are displayed very comfortable
Color transitions are also very smooth, especially when shown in both the grayscale transitions and the color transition test plots.
It's a great fit to enjoy a scenic documentary like Earth Pulsating.
The brightness of the display in different positions is also "average", and the text in the four corners is as bright and clear as the central text;
Peak brightness this is very full, like the "Matrix" full of screen green light, explosive fire, strong sunlight on the face and other scenes, it can be very good, in the "bright up" at the same time the picture contrast is also in, content details are not lost.
The viewing angle does not live up to the OLED panel, the 178 ° viewing angle is worthy of the name, the content seen is basically no color cast, and a large group of friends are no problem to watch together.
However, it is not enough to show a static map to pass the level!
Because of the scoring terms such as motion blur, motion compensation, and input delay, it can only be examined with dynamic pictures.
In the process of "holding a license to touch the fish" to play "Battlefield 5", Jiguojun almost did not feel that there was an input delay between the host and the TV, the game loaded very quickly, the motion blur of the screen was also very good, very real There will be no high-speed movement too clear, let people dizzy feeling, must be praised!
Watching football games is also very comfortable, there is no smearing, residual shadow phenomenon, in line with the 120Hz refresh rate screen performance!
In general, the whole amount of color content is to tell you that tv does not rely on metaphysics, but technology!
Therefore, if you want to buy a good TV that can please the "eyeballs", it is very necessary to master some basic technical knowledge, accumulate some film materials that you usually like to watch, and help yourself to judge whether a TV is suitable for you.
In addition to high color accuracy and excellent picture quality performance, in terms of other parameter performance, Skyworth S82 also maintains the flagship level:
Whether it is "Game of Thrones", a work that can only be seen clearly by playing a flashlight; or a colorful blockbuster such as "Alice in Wonderland"; whether it is a console game or a cinema blockbuster, the picture performance on the S82 TV is very close to what the human eye really sees, and the grandeur of the big scene, the sense of high-grade, and the details of the picture that make people "creepy" are almost perfectly presented, and the charm of the big production is fully revealed.
In terms of sound quality, it is quite good, supporting Dolby Atmos sound, equipped with 2 10W speakers and 1 20W subwoofer, which is suitable for the general audience! Whether it's watching a blockbuster movie or playing a console game, you can cooperate with the picture and immerse yourself in it.
* Rear sound position
Depending on the speed is also very guaranteed, built-in MediaTek flagship 8K chip S900 (MT9550), 4GB + 64GB collocation, to accommodate a variety of TV app, silky across 4K blockbusters and game masterpieces is basically no problem drops.
Moreover, the appearance design is also quite good, using Skyworth OBM thin technology, the side is very thin, the bracket below is removable, with its own VESA interface, placed on the cabinet or on the wall are OK.
In general, the comprehensive performance of this Skyworth S82 is worthy of the name of the OLED flagship, Skyworth as the leader of the domestic OLED TV, the flagship screen color accuracy produced by the production is still quite outstanding, the high color brigadier will be different types of test clips and film and television content are very good, the comprehensive picture quality performance is eye-catching, in the words of Guo Xiaoyi and other colleagues, the testing process is to do SPA for the eyeballs tortured by the skin polishing beauty filter set.
Of course, I guess there must be some people wondering, do I really need such a TV? How big a difference can flagship TVs and ordinary TVs make in our daily practical use? Don't worry, the next push, we will take you to reveal what this TV can see, where the advantages are, you can crouch a wave.
