Problems solved by technology

[0004] Because it takes time for the liquid crystal to respond, it usually takes a while for the liquid crystal to switch to the position corresponding to the data after the data is refreshed. Therefore, the overdrive technology is used in the LCD panel. When debugging the overdrive brightness value lookup table, in the software Both use the exhaustive test method to find the appropriate lookup table value. The biggest problem with the exhaustive method is that it takes too long

Abstract

The invention discloses a debugging method of an overdrive brightness value lookup table, a use method and a display panel. The debugging method includes the steps of: using a preset gray scale interval to exhaust all gray scales of a usable gray scale range as a previous frame gray scale M, using a preset gray scale interval to exhaust all gray scales of a usable gray scale range as a current frame target gray scale N, measuring the actual brightness, and recording all the actual brightness values into the overdrive brightness value lookup table correspondingly, wherein the measurement process of each actual brightness value includes: taking the gray scale M as the previous frame gray scale, adopting the gray scale N as the current frame target gray scale, and using optical equipment to measure the actual brightness value of the current frame. The debugging method provided by the invention can reduce the debugging time.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a debugging method for an overdrive luminance value lookup table, a use method and a display panel. Background technique [0002] With the development and progress of science and technology, liquid crystal displays have become the mainstream products of displays due to their thin body, power saving and low radiation, and have been widely used. Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal panel and a backlight module. The working principle of the liquid crystal panel is to place liquid crystal molecules between two parallel glass substrates, and apply a driving voltage on the two glass substrates to control the rotation direction of the liquid crystal molecules, so as to refract the light from the backlight module to produce a picture. [0003] Among them, Thin Film Transistor-Liquid Cry...
