Problems solved by technology

This approach is not flexible enough to support multiple displays
When we conduct production tests or repairs on LCD displays, we need to replace different display screens. Every time we replace a display screen with different parameters, we need to replace the corresponding software to perform GAMMA correction on the new display screen, which is time-consuming and laborious.
None of the existing monitors can support multiple displays

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0024] The display screen of the liquid crystal display often uses the GAMMA data stored in the memory to perform GAMMA correction on the color of the display screen, so as to avoid problems such as color cast in the displayed image. By testing for each display screen, the GAMMA data of different display screens are obtained, and then these multiple groups of GAMMA data corresponding to different display screens are stored in the memory (that is, written into the code or stored in an external memory), so that Called when gamma correction is applied to the display. In this way, other stored GAMMA data can be called directly without replacing software during production test or maintenance and replacement of LCD screens, and can support GAMMA correction for different LCD screens, which is convenient to use.

Abstract

The invention discloses an LCD which can support GAMMA correction to a plurality of display screens and a preparation method thereof. The LCD which can support GAMMA correction to a plurality of display screens comprises: a memory applied to storing GAMMA data and carrying out GAMMA correction to the display screens, wherein, the memory is stored with at least two groups of GAMMA data corresponding to different display screens. As the memory of the LCD is stored with at least two groups of GAMMA data corresponding to different display screens, no software needs to be replaced during production testor during maintenance and replacement of the display screens, and the display can directly call other GAMMA stored data and support GAMMA correction to different display screens. The application is very convenient.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a liquid crystal display capable of performing GAMMA correction on the chromaticity distortion of the display and a manufacturing method thereof. Background technique [0002] In the TV system, red, green, and blue (RGB) are the three primary colors, and the transmission and transformation of signals are carried out according to these three colors. Due to the non-linearity in the transmission process, there is brightness distortion in the reproduced color, and there is also chromaticity distortion. Therefore, GAMMA correction must be performed on these three primary colors to ensure that the final displayed color and the original color have a linear relationship. [0003] With the development of TV technology, LCD TV has gradually become the main product in the market. However, there are many manufacturers of LCD screens, and the technologies used are also different. The parameters of...
