Setting method of display panel and display panel

A display panel, comprising a memory and a processor, wherein through calling computer programs stored in the memory, the processor is configured to:

• acquire a first chromaticity information of a first gray scale and a second chromaticity information of a second gray scale, and the first gray scale and the second gray scale are any two gray scales that are different and set at intervals;
• acquire a first difference value between the first chromaticity information and the second chromaticity information;
• and
• adjust gray scale voltage of at least one of the first gray scale or the second gray scale when the first difference value is greater than a preset difference threshold, to adjust a corresponding chromaticity information of the at least one of the first gray scale or the second gray scale, wherein a second difference value between the first chromaticity information and the second chromaticity information after adjustment is less than the first difference value.
