In 2023, the TV industry will face an unprecedented complex internal and external environment, and in this context, "involution" seems to have become the strongest weapon for the industry to move forward in a downturn. The decline in market demand and the improvement of user demand are constantly stimulating the research and development potential of various manufacturers for new technologies, and in order to be able to get rid of competitors, manufacturers are also constantly challenging their "own limits". So much so that in the past year, products with high brightness, high contrast, and high refresh rate have sprung up in large numbers. So under the "parameter involution", which technology will shine this year?Standing at the end of the year, let's take stock of TV display technology in 2023.
Peak BrightnessBreak through the ceiling of the TV industry
When it comes to brightness, we have to mention the concept of "peak brightness". Unlike the traditional sense of screen brightness, "peak brightness" refers to the maximum limit brightness that a screen can support for a short period of time. To put it simply, "peak brightness" represents the maximum potential that the screen can excite in the normal lit state, and this "peak brightness" can only occur in a specific state and does not last for a long time. But even so, there are still many manufacturers who are obsessed with the improvement of "peak brightness", why is that?
To a certain extent, brightness determines the ability of the TV screen to reproduce the real scene, and the higher the "peak brightness", the higher its dynamic range, so the more detail the TV screen shows. As we all know,Dark field is a test environment that tests the performance of TV screens,In this scene,The higher the "peak brightness"The product can show more picture details,For example, the starry sky at night,"Peak brightness"We can see countless shining stars。 Another example is a dark alley with no lights, and we can also see the gravel-covered path under the "peak brightness". Compared with traditional TV shows and variety shows, games and movies are the best stage for "peak brightness" to display their skills.
In fact, the strength of "peak brightness" is far from this, and it also has a non-negligible role in the improvement of color. With the same color gamut, the increase in "peak brightness" contributes to the improvement of the color space, and the color expression becomes more accurate and rich. At the same time, "peak brightness" can also effectively eliminate the interference of external ambient light, further improving the user's viewing experience. To some extent, this is similar to projection, the higher the brightness of the projection, the stronger the light resistance, the better the picture display. However, due to the difference in technical principles, TVs do not feel the intensity of the light source as clearly as projection.
In terms of "peak brightness" alone, TCL is currently at the forefront of the industry. At the beginning of this year, TCL launched a flagship product with a "peak brightness" of 5000nits, pushing the image quality to a new height in one fell swoop. You know,Before that, the vast majority of TVs on the market had their "peak brightness" on average2000nits, and 5000nits"peak brightness"It can be called the existence of breaking through the brightness ceiling of the TV industry。
So in summary, TVs with high peak brightness will see more detail on the bright parts of the picture than TVs with low peak brightness. However, at present, the content that can really stimulate the full potential of "peak brightness" is very limited, especially for users who mainly focus on variety shows and news, and the choice of "peak brightness" should be considered as appropriate. If you are a enthusiast player who focuses on e-sports, video and audio, etc., the higher the "peak brightness", the better.
The trend of large size makes "backlight partitioning".The scene is aggravated
As a technical term often mentioned at the press conference,"Backlight partition"Not a new technology,In the early stage of the development of LCD TV,In order to effectively improve the light leakage of LCD TV panel,So as to achieve more accurate control of the picture display,"Backlight partition"It has appeared in the technology library of many TV manufacturers。 But why is it that in recent years, there have been more and more mentions of "backlight partition", and everyone's attention to it has become higher and higher?
In fact, a very important reason is that the market is accelerating towards the trend of large size,According to the information released by relevant data research companies,20231-8monthThe average size of China's color TV market has reached59.7 inches, an increase of 3 from the same period last year6 inches. In addition, the fastest-growing size in China's color TV market in 2023 is 75 inches, with a market share of 180%, an increase of 68 percentage points;The willingness to consume super-large sizes above 80 inches continues to increase, of which the market share of 85-inch products is 53%, an increase of 33 percentage points, 98-inch product market share reached 06%, an increase of 03 percentage points. According to the above data, it can be seen that the continuous increase in viewing demand has played a role in boosting the popularity of large-size TVs.
As the screen size gradually increases, the role of "backlight partitioning" is infinitely magnified. In order to better control the image quality performance of each area of the screen, the number of "backlight zones" has gradually increased in recent years. Although the birth of backlight partitions has made great progress in the development of picture quality in the TV industry, for a long time, the specific definition of partition level has never been clear in the industry. Therefore, the discussion of the topic of "TV partition backlight standard" in the industry has been high. To this end, the domestic market last year will TV"Backlight partition"The standard has been unified,Divided into dozens of divisions、100 divisions、300 divisions and 2,000 divisions,It provides consumers with a more direct and effective reference standard for picture quality in TV purchase。
According to the standard, there is a correlation between the "backlight zone" level and the image quality effect, the higher the level, the better the image quality effect, and the higher the level, the larger the screen size. But one thing to emphasize is that,Due to technical limitations,There is a common commonality of TVs on the market today:The more "backlight partitions" you have, the higher the cost, and the pricing will increase. If you are an enthusiast movie-watcher, the larger the screen, the more "backlight partitions" the better, after all, the visual shock brought by the giant screen is not comparable to ordinary products.
The next generationGame consoles boost the popularity of "high-brush TV".
In the past few years, the advent of next-generation game consoles has brought a lot of changes to the TV industry. With the increase in the attention of home consoles, people have begun to discover the fun of playing games in the living room, so "high brush TV" has been welcomed by the market. The data shows that from January to August 2023, the retail volume of TVs with screen refresh rate and above in China's color TV market will account for 26%.1%, an increase of 106 percentage points, and the layout of the high brush function is also moving towards a higher level. Because it is better than other technical products in terms of adaptability,Therefore, in the market,The type of TV that supports high-brush screen display contains huge room for development。
As more and more brands join into"High brush TV"Competition,"High brush TV"The configuration has also begun"Roll",Some brands have successively launched TVs with higher refresh rates,from120hzto144hz,There are even 240HzUltra-high refresh rate TVs,It seems that the higher the refresh rate, the more attractive it is to users。
At present, it is more recommended to choose "full-channel120hzTV",What kind of TV can be called full-channel120HzTV?The following points need to be met at the same time. First of all,Full-channel120HzTV should be equipped with a4K 120Hz screen,It can meet4K 120HzPicture display function,Show the excellent picture performance effect of high brush and high resolution。 Secondly, when buying a TV, you need to pay attention to whether the decoding chip of the TV can support 120Hz**Decoding. Finally,When purchasing, confirm whether the TV is using a full-blooded versionHDMI2.1 interface, which can achieve a maximum of 48Gbps data transmission, and supports MEMC, VRR, ALLM and other functions. Support the above three points at the same time120HzTV,It is really able to support4K 120HzPicture input and display of fully high-level brush game TV。 With such hardware support, we were able to enjoy both the high definition of native 4K image quality and the excellent picture brought by 120Hz high smoothness.
Write at the end:
In the past few years, China's color TV market is shifting to the stock market at an "amazing" speed, and in this context, technology upgrading and "parameter involution" seem to have become a Xi thing. Although products with higher parameters and newer technology can bring a shocking visual impact to our movie, in the author's opinion, the competition of products should not be just a simple data ratio. Only the reasonable adaptation of performance and usage scenarios can bring users a better experience. Therefore, when buying TV,The author suggests that users should choose the most suitable product for their living room according to their own usage scenarios, entertainment needs and budget,Remember not to be simply taken away by performance parameters。
