Embodiment Construction

[0015] see figure 2 , which is a schematic circuit block diagram of the display device of the present invention. The display device 2 includes a video signal processing board 30 , a display module 40 and a gamma memory 50 . The video signal processing board 30 is used to receive RGB signals input from the outside world, and the RGB signals input from the outside world are converted into TTL signals after being transmitted and processed by the video signal processing board 30 . The gamma memory 50 is used for storing the parameter data of the gamma curve of the RGB signal provided by the external system and compiling the program of the gamma curve of the RGB signal. The display module 40 is used to receive the parameter data of the gamma curve of the RGB signal stored in the gamma memory 50 and the TTL signal provided by the video signal processing board 30, and then individually adjust the RGB signal in the TTL signal according to user requirements. . The pre-stored parame...

Abstract

The invention provides a display device and a color adjusting method thereof. The display device comprises a gamma memory, a video signal processing board and a display module group. The gamma memory is used for storing parameter data of a gamma curve of RGB signals provided by an external system and a program of the gamma curve for compiling the RGB signals. The video signal processing board is used for receiving the RGB signals input by the external, and the RGB signals input by the external is converted to TTL signals after transmission processing through the video signal processing board. The display module group is used for receiving the parameter data of the gamma curve of the RGB signals which are stored in advance in the gamma memory and the TTL signals provided by the video signal processing board, thereby the RGB signals in the TTL signals can be independently adjusted according to the requirements of a user. The display device can realize independent adjustment of a RGB message expressed by YUV signals.

Description

technical field [0001] The invention relates to a display device and a color adjustment method thereof. Background technique [0002] At present, display devices are not only widely used in home computers and televisions, but also in portable computers, mobile phones, and vehicle-mounted or airborne audio-visual entertainment equipment. The color display effect is a very important part of the display device. Therefore, all relevant upstream and downstream manufacturers are committed to improving the color display effect of the display device in order to provide products that meet the needs of consumers. [0003] see figure 1 , which is a schematic circuit block diagram of a display device in the prior art. The display device 1 includes a video signal processing board 10 and a display module 20 . The video signal processing board 10 includes a decoding chip 11 and a scaling chip 12 . The display module 20 includes a driver chip 21 and a display panel 22 . External red, g...
