Abstract

The present application discloses a debugging method and device for a display panel. The method includes: acquiring a fan-out moiré area of ​​a display panel, dividing the fan-out moiré area along a first direction into several first sub-areas, wherein each first sub-area is provided with a first binding point ; According to the initial grayscale value of the first binding point, obtain the fan-out moiré degree of the corresponding first subregion and the first correction value; According to the first correction value, perform grayscale compensation on the corresponding first subregion, and obtain The first display screen after compensation. The present application solves the problem of uneven charging in the area of ​​the data integrated circuit, improves the moiré phenomenon in the fan-out area, ensures the uniformity of image quality, and improves the display quality of the product.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a debugging method and device for a display panel. Background technique [0002] Large-size panels have the problem of RC delay, which leads to uneven charging of pixels in each area and affects product quality. The length of the data line in the middle of each data integrated circuit (Data IC) of the LCD panel is shorter than that on both sides, that is, the resistance and capacitance on the center line of the data IC is smaller than the resistance and capacitance on the line at the border. Therefore, in a short charging time, the brightness of the edge portion of the data integrated circuit is obviously lower than that of the middle portion, and this phenomenon is called fan-out moiré (fan-outmura). [0003] In the prior art, the charging time of the wires at the edge and the middle of the data integrated circuit is controlled to improve the fan-out moiré effect. H...
