Problems solved by technology

In order to improve the performance of LCD TVs in terms of color and contrast, technologies for dynamically configuring the backlight according to the content of the screen have gradually emerged in the industry, namely: improving contrast through global dynamic and partition dynamic backlight technology, reducing power consumption, and enhancing color saturation through color optimization technology and layering, but the current mainstream technical solutions are to design the driving system for the backlight alone, which requires the design of dynamic backlight timing, which not only increases the system cost, but also is not conducive to system implementation, and it is not easy to manage and upgrade online in the future.

Abstract

The present invention relates to a dynamic backlight control method and device, wherein the dynamic backlight control method adopts a single video processing chip, including decoding the video processing chip, analyzing the decoding output according to the video image partition array configuration, and extracting the partition backlight value; the video processing The chip performs brightness correction according to the video image partition array configuration; the video processing chip outputs the backlight through the peripheral driving circuit.

Description

technical field [0001] The invention relates to a liquid crystal television and a display, in particular to a dynamic backlight control method and device. Background technique [0002] At present, most domestic and foreign TV manufacturers list LCD TV as a terminal technology product. It has the advantages of light and thin portability, rich colors, large resolution, high definition, green environmental protection, low power consumption and long service life. However, compared with other Different types of TVs still have gaps in contrast and color saturation. In order to improve the performance of LCD TVs in terms of color and contrast, technologies for dynamically configuring the backlight according to the content of the screen have gradually emerged in the industry, namely: improving contrast through global dynamic and partition dynamic backlight technology, reducing power consumption, and enhancing color saturation through color optimization technology And layering, but ...
