Claim 2:
3. 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 acquiring the brightness value of each of the sub-regions when the target color is displayed in the display region comprises:
acquiring, in the case that no force is applied to the display panel, a first brightness value of each of the sub-regions when the target color is displayed in the display region, and acquiring, in the case that a force is applied to the display panel by a test fixture, a second brightness value of each of the sub-regions when the target color is displayed in the display region;
and 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 light-leakage degree of the display panel based on an average of the first brightness values of the plurality of sub-regions and a first brightness value of the light-leakage sub-region, and determining a second light-leakage degree of the display panel based on an average of the second brightness values of the plurality of sub-regions and a second brightness value of the light-leakage sub-region; and
the method further comprises:
determining, based on the first light-leakage degree, the second light-leakage degree and a deformation amount of the display panel under the force, a first light-leakage sensitivity caused by a unit of the deformation amount, wherein the first light-leakage sensitivity is negatively correlated with both the first light-leakage degree and the deformation amount and positively correlated with the second light-leakage degree.
