Claim 4:
5. The method according to claim 3, wherein acquiring, in the case that the force is applied to the display panel by the test fixture, the second brightness value of each of the sub-regions when the target color is displayed in the display region comprises:
acquiring, in the case that a first force is applied to the display panel by the test fixture, a first target 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 second force is applied to the display panel by the test fixture, a second target brightness value of each of the sub-regions when the target color is displayed in the display region, wherein a direction of the first force is opposite to a direction of the second force;
determining the second light-leakage degree of the display panel based on the average of the second brightness values of the plurality of sub-regions and the second brightness value of the light-leakage sub-region comprises:
determining a first target light-leakage degree of the display panel based on an average of the first target brightness values of the plurality of sub-regions and a first target brightness value of the light-leakage sub-region, and determining a second target light-leakage degree of the display panel based on an average of the second target brightness values of the plurality of sub-regions and a second target brightness value of the light-leakage sub-region;
determining, based on the first light-leakage degree, the second light-leakage degree and the deformation amount of the display panel under the force, the first light-leakage sensitivity caused by the unit of the deformation amount comprises:
determining, based on the first light-leakage degree, the first target light-leakage degree and a first deformation amount of the display panel under the first force, a first reference light-leakage sensitivity caused by a unit first deformation amount, and determining, based on the first light-leakage degree, the second target light-leakage degree and a second deformation amount of the display panel under the second force, a second reference light-leakage sensitivity caused by a unit second deformation amount; and
the method further comprises:
determining an average of the first reference light-leakage sensitivity and the second reference light-leakage sensitivity as a second light-leakage sensitivity caused by the unit first deformation amount and the unit second deformation amount.
