Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

[0040]As described in the background art, in the prior art, when the display panel is driven in a digital driving manner, there are problems of gray scale redundancy, low scanning utilization rate and insufficient scanning time during gamma debugging. The inventor found that the reason for the above problem is that there are many uncontrollable factors in the process of forming the display panel, such as the backplane, LED chip production, transfer, repair and other processes, and the existence of dust particles and other reasons, ...

Abstract

The embodiment of the invention discloses a gamma debugging method and device for a display panel, and the method comprises the steps: at least adjusting a compensation subframe parameter corresponding to a compensation subframe according to the target brightness of a to-be-compensated display gray scale, the actual test brightness corresponding to an original subframe gray scale adjacent to a coordinate point of the target brightness of the to-be-compensated display gray scale on a test curve, and the target brightness of the to-be-compensated display gray scale; and when a difference value between the adjusted actual debugging brightness and the target brightness of the display gray scale to be compensated is smaller than a set threshold value, determining an original subframe parameter and a compensation subframe parameter corresponding to the original subframe as target gamma data of the display gray scale to be compensated. According to the technical scheme of the embodiment, gray scale redundancy during gamma debugging can be reduced, so that the scanning utilization rate is improved, and the problem of insufficient scanning time is solved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a method and device for gamma debugging of a display panel. Background technique [0002] With the development of display technology, in order to improve the screen quality, it is usually necessary to perform gamma adjustment on the display panel. [0003] In the prior art, when the display panel is driven in a digital driving manner, there are the problems of gray-scale redundancy, low scanning utilization rate, and insufficient scanning time during gamma debugging. SUMMARY OF THE INVENTION [0004] The present invention provides a gamma debugging method and device for a display panel, so as to reduce gray-scale redundancy, improve scanning utilization, and increase line scanning duration. [0005] In a first aspect, an embodiment of the present invention provides a gamma debugging method for a display panel, including: [0006] Determine the disp...
