Problems solved by technology

The overdrive table of the display device is usually adjusted and obtained in the original installation state where the system chip does not work before leaving the factory. When the system chip controls the display device to enter a different display state, the parameters in the original overdrive table are not optimal. The best value makes the dynamic taste change, and it is easy to produce dynamic trailing or color dragging, which affects the dynamic look and feel of the picture. If you re-adjust the overdrive table at this time, it will waste a lot of time. If you set different overdrive for different display modes table, then multiple overdrive tables take up more storage space, which will increase the cost of the display device

Embodiment Construction

[0031] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0032] see figure 1 , the present invention provides a method for adjusting an overdrive meter of a display device, comprising the steps of:

[0033] Step S1, providing a display device. The display device stores an original overdrive table. The original overdrive table includes a plurality of original previous frame gray levels, a plurality of original current frame gray levels and a plurality of original overdrive gray levels, each original overdrive gray level is associated with an original previous frame gray level and an original Combination corresponding to the gray scale of the current frame.

[0034] Specifically, see figure 2 , the display device includes a display panel 1 , a timing controller 2 electrically connected to the dis...

Abstract

The invention provides a method for adjusting an overdrive table of a display device. According to the method for adjusting the overdrive table of the display device, the original gamma curve and theactual gamma curve of the display device are measured, and the mapping relation between the original gray scale and the actual gray scale is obtained; a each original previous frame gray scale and each original current frame gray scale in the original overdrive table are adjusted into actual gray scales mapped by the original gray scales with the same numerical values to obtain a plurality of adjusted previous frame gray scales and adjusted current frame gray scales; A plurality of adjusted overdrive gray scales are generated by utilizing a plurality of adjusted previous frame gray scales, a plurality of adjusted current frame gray scales and the original overdrive table, so that an adjusted overdrive table is obtained, different adjusted overdrive tables can be generated under different actual display modes, and the dynamic display effect of the display device under different actual display modes is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for adjusting an overdrive meter of a display device. Background technique [0002] In the field of display technology, flat panel display devices such as liquid crystal display devices (Liquid Crystal Display, LCD) have gradually replaced cathode ray tube (Cathode Ray Tube, CRT) display devices. The liquid crystal display device has many advantages such as a thin body, power saving, and no radiation, and has been widely used. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. Generally, a liquid crystal display panel consists of a color filter (Color Filter, CF) substrate, a thin film transistor (Thin Film Transistor, TFT) array substrate, a liquid crystal (Liquid Crystal, LC) and a sealant sandwiched between the color filter subs...
