Peak brightness
First of all is the peak brightness, when it comes to the factors that affect the quality of the TV, brightness is definitely the most important, now we all know HDR (high dynamic range), that is, the highest peak brightness that the TV display panel can achieve, the brightness of which is not the brightness in the conventional sense, but a dynamic range, is a range of the panel from black to bright, how bright the panel is when it is bright, then how black it is when it is black, when the peak brightness reaches more than 1000nit, then the TV screen can present more details, The contrast will also be greatly increased.
In the previous CRT cathode ray tube era, the brightness of the TV is very low, the brightness standard of the SDR (standard dynamic range) at that time was only 100nit, the particularly bright and dark details in the TV were completely invisible, the night and noon pictures looked completely blurry, and with the advancement of science and technology, HDR (high dynamic range) has gradually replaced the SDR (standard dynamic range), and the peak brightness standard of HDR has directly increased to more than 1000nit. In the end, the picture quality of a TV, HDR peak brightness must be the most important.
Many TVs claim to be able to play HDR movies, but the peak brightness of the TV is less than 400nit, the so-called can play HDR (high dynamic range) movies is meaningless, in general, the standard brightness of LCD TVs reaches more than 800nit, OLED TV standard brightness needs to reach more than 500nit, at this time the playback is the real HDR film, as for HDR10+ and Dolby Vision is to HDR (high dynamic range) upgrade again, The peak brightness requirements for the TV are higher, so the first thing to buy a TV is to see the peak brightness.
Dynamic backlit partitioning
The characteristics of liquid crystal technology determine that lcd TV in the display of pure black picture, there will be a situation of light leakage, it is impossible to achieve pure black pictures like OLED TV, and dynamic backlight partition is to make up for the leakage of these defects and was born, dynamic backlight partition technology is to divide the TV backlight into N areas, the display of black part of the partition backlight will be directly turned off, for LCD TVs, backlight partitions are definitely the more the better, the general LCD TV backlight partition in 60 ~ 100 or so , and MiniLED will reach thousands of partitions.
The actual performance of the dynamic backlight partition is not only to see the number of backlight partitions, but also to see the actual dynamic light control effect, if the light control is not good enough, the actual picture experience is not as good as the TV without the backlight partition, at this point, Sony TV has absolute strength, many brands of TVs Even if there are 60 backlight partitions, the actual light control effect is not as good as the 32 backlight partitions of Sony TV, which is why Sony TV will squeeze toothpaste upgrades, it is indeed because there is no opponent to compete ah!
Color range
With a higher peak brightness display screen details, but the color performance of the picture is good or not, it is related to the screen's color gamut, color depth and color accuracy, the higher the color depth, the higher the resolution of the TV screen, the 10bit color depth is better than the 8bit color depth TV, the wider the color gamut, the richer the color gamut, the current 4K TV is basically a wide color gamut, the higher the wide gamut color accuracy, the more realistic the picture display, and the color criterion is mainly based on the display level.
Generally speaking, TV manufacturers will give priority to improving the color gamut, because the picture under the high color gamut is more colorful and colorful, and it is easier to stand out in a bunch of TVs, thus attracting the attention of consumers, while the color accuracy and color depth can be saved, and the Sony TV is very good in terms of color gamut, color depth and color accuracy.
Viewing angle
Tv viewing angle will also affect the picture performance, generally speaking, IPS hard screen TV even in the case of 178 ° will not appear color cast problem, so there is no problem of viewing angle, and VA soft screen TV as long as the human eye line of sight and TV have a certain angle, the color will immediately appear deviation, but the color performance of VA soft screen is better, so the high-end TV is VA soft screen, in order to overcome the VA soft screen viewing angle problem, the major TV manufacturers have also studied their own coping strategies, Among them, the viewing angle of Sony and Samsung LCD TVs is the best.
Picture quality chip
With excellent hardware facilities, but to show the film, but also need the blessing of the picture quality chip, an excellent picture quality chip can not only better analyze the film, but also enhance the picture quality of the original film, excellent TV manufacturers have their own developed picture quality chips, such as Hisense's U + super picture quality chip and Samsung's NEO quantum dot 4K processor are very famous picture quality chips, and Sony has launched an XR cognitive chip in the past two years, which has both super analysis and picture quality enhancement functions for the film.
Screen tuning (video optimization)
An excellent TV, naturally not open excellent picture adjustment, we often see different brands of TV, even if it is the same configuration, the actual picture played out is not the same, and the same brand of TV, each year's product tuning style is not the same, such as the past two years Sony's TV color is more and more biased towards authenticity, and not as bright as before, picture tuning not only requires strength, but also needs enough aesthetics, which domestic TV also needs a certain amount of time to catch up.
Picture lag and smear issues
For sports event lovers and gamers, screen latency is crucial, IPS hard screen due to the inherent advantages, generally do not need to worry about screen delay, and VA soft screen on the strength of the TV is a test, excellent TV manufacturers can control the delay within 6ms, our common MEMC motion compensation, VRR variable refresh rate and ALLM automatic low latency are to solve the problem of screen delay and smearing and the birth of the technology, and these technologies often only appear on high-end TVs.
Parameter configuration of the Sony X95J
We can use Sony's LCD flagship Sony X95J last year as an example, one by one to look at the parameters mentioned above, sony X95J standard brightness is 1100nit, HDR peak brightness is more than 1200nit, whether it is playing HDR movies, or HDR10+ or Dolby Vision, can be easily competent. In terms of the number of backlit partitions, 65, 75 and 85 inches have 60, 84 and 112 backlit partitions respectively, which is absolutely good enough and is also the top in the current LCD TV.
In terms of screen performance, Sony X95J has a 10bit color depth, can support the display of 1 billion colors, can ensure that the picture color transition is uniform, DCI-P3 color gamut coverage is 95%, reaching the standard of wide color gamut, color accuracy performance has also reached the level of the display, Sony X95J whether the screen color gamut, color depth and color accuracy are very good, as for the picture quality processing chip and picture quality tuning is not to say, directly put a Sony X95J actual screen picture, we can watch the actual picture effect on the line.
It is worth mentioning that the recent price of Sony X95J has dropped to the lowest, under the preferential treatment of the e-commerce platform, the price of 65-inch Sony X95J has dropped from the original 12999 yuan to 8299 yuan, a full reduction of 4700 yuan, 75 inches and 85 inches of discounts more, as a flagship LCD TV that is currently the strongest on the market, there is a need for small partners can start.
