Adaptation device and display device

Abstract

The invention relates to an adaptation device and a display device, and the adaptation device comprises an identification module which is used for obtaining the LED color temperature block classification information of a backlight module; a control module which is connected with the identification module and a time sequence controller, and r is used for outputting a corresponding control signal tothe time schedule controller according to the color temperature block classification information, so that the time schedule controller performs color compensation correction by calling and locking acorresponding RGB gain value, and sets the current output to the LED lamp string by outputting a feedback signal to a microcontroller. According to the invention, different RGB gain values are matchedaccording to different batches of backlight assemblies; the current output to the LED lamp string is adjusted at the same time, consistency of color specifications and brightness specifications of different batches of products is achieved, the problem that all components are difficult to put into production is solved, and the backlight modules of different batches have the LED lamp string with different color temperature blocks.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an adaptation device and a display device. Background technique [0002] Existing liquid crystal displays have the advantages of thinness, small size, etc., and also have the advantages of no radiation, low power consumption and relatively low manufacturing cost. The liquid crystal display mainly includes an array substrate, a color film substrate, a liquid crystal layer sandwiched between the array substrate and the color film substrate, and a backlight module located under the array substrate. LED light strings are mostly used in the backlight components of the existing liquid crystal displays. glowing source. [0003] Specifically, the main components of a liquid crystal display include an LCM (display module) and a CTP (cover glass), wherein the LCM includes a backlight assembly and an LCD (display panel), and the product specifications of the LCM (such as chromatic...

AI Technical Summary

Problems solved by technology

At present, no matter what kind of color temperature LEDs are used, they are all matched with the same RGB gain value, resulting in large differences in optical measurement color, obvious visual color difference, and low consistency.

In addition, even if the LEDs of different color temperature blocks are matched with different RGB gain values, there will still be problems in the production of backlight components and PCB boards, the quantity of production is not clear and the brightness of different RGB gains varies greatly.
