Claim 0:
1. A method for determining a light-leakage degree of a display panel, applicable to a light-leakage detecting device, wherein a display region of the display panel comprises a plurality of sub-regions, and the method comprises:
acquiring a brightness value of each of the sub-regions when a target color is displayed in the display region;
determining a sub-region with the brightness value greater than or equal to a brightness threshold as a light-leakage sub-region; and
determining the light-leakage degree of the display panel based on an average of brightness values of the plurality of sub-regions and the brightness value of the light-leakage sub-region;
wherein determining the light-leakage degree of the display panel based on the average of brightness values of the plurality of sub-regions and the brightness value of the light-leakage sub-region comprises:
determining a first ratio of the brightness value of the light-leakage sub-region to the average of brightness values of the plurality of sub-regions;
determining a second ratio of an area of the light-leakage sub-region to an area of the display region; and
determining the light-leakage degree of the display panel based on the first ratio and the second ratio, wherein the light-leakage degree is positively correlated with the first ratio and positively correlated with the second ratio;
wherein the plurality of sub-regions comprises at least two light-leakage sub-regions; and determining the light-leakage degree of the display panel based on the first ratio and the second ratio comprises:
acquiring at least two products by respectively determining a product of the first ratio and the second ratio corresponding to each of the at least two light-leakage sub-regions; and
determining the light-leakage degree of the display panel based on a sum of the at least two products.
