TV partition backlight standards are announced, and industry technology and information transparency continue to accelerate

There has always been a lot of debate about whether partitioned backlights must pursue greater quantities, and the "TV Zoned Backlight Standard" recently released by the industry may be able to give the answer. 

In the field of screen display technology, partitioned backlight technology has shone in the past two years. Its characteristic is that the entire backlight is divided into N areas. Each area can be independently switched or adjusted for light and dark, which can be controlled more accurately, so that the light and dark levels of the TV picture are more distinct, the visual experience is closer to reality, and the color sense is more precise. for comfort.

So what is the most appropriate number of partitions? Do we have to pursue the ultimate? Taking 75-inch TV products as an example, the standard divides the number of TV backlight partitions into six levels. In the dozens of levels, the contrast is less than 2.5X, which has no practical significance for improving the picture quality; when it reaches the 100-level partition and the 300-level partition When the contrast starts to increase significantly, the effect is basically comparable to the picture quality of OLED TVs; but in the division from level 300 to level 2,000, the contrast growth gradually slows down, and it is not until the division above level 2,000 that there is a significant change again. .

Considering that more partitions means more LED chips and IC chips are used in the production process of the product, the cost will also increase accordingly. If you are only choosing between three-hundred-level and five-hundred-level partitions, choose the latter. There is not much need, after all, the doubled purchase cost does not bring about a corresponding multiple increase in experience.

Therefore, it is wiser to choose a solution with a higher quality-price ratio, such as TCL’s Mini LED TV. Its lamp beads use light-control lighthouse technology, which can accurately control light, have stronger penetration, and greatly reduce halos. , thus greatly improving the image quality. TCL's Mini LED lamp beads have more than 2 times improvement in image quality compared to ordinary lamp beads Mini LED zone light control. Therefore, TCL TVs have better image quality than TVs with the same number of zones and are more affordable.

In the direction of the development of partitioned backlight technology, TCL obviously does not blindly pursue the number of partitions, but focuses on technical improvements and breakthroughs to achieve better image quality with fewer partitions. This approach not only complies with the "marginal benefit principle" in the "Standards", but also can do a better job in cost control, ensuring that consumers can purchase products with better image quality at more favorable prices and enjoy the benefits of technological development.
