Abstract

Claims (51)

1 . A model adjustment apparatus, applied in a display panel, wherein the display panel comprises a first area and a second area, a life attenuation value of the first area is greater than a life attenuation value of the second area, and the apparatus comprises:

a processor; and

a memory for storing a processor-executable instruction;

wherein the processor is configured to:

display a first image;

compensate brightness of at least one of the first area or the second area in the first image according to a compensation value calculated by a preset model;

receive an adjustment value from a user for the compensation value; and

adjust a parameter in the preset model according to the adjustment value;

wherein the processor is further configured to display at least one of a brightness parameter or a grayscale parameter corresponding to the first image when displaying the first image;

wherein the processor is further configured to display an adjusted first image according to an adjustment of at least one of the brightness parameter or the grayscale parameter by the user;

wherein the processor is further configured to:

compensate, after each time the first image is adjusted, a brightness of at least one of the first area or the second area in the adjusted first image according to a compensation value calculated by the preset model;

receive a respective adjustment value from the user for a respective compensation value calculated by the preset model each time; and

adjust the parameter in the preset model according to adjustment values received in multiple times.

2 . The apparatus according to claim 1 , wherein the display panel comprises an organic light emitting diode display panel.

3 . The apparatus according to claim 2 , wherein the first area is a non-rollable area, and the second area is a rollable area.

4 . The apparatus according to claim 1 , wherein the brightness parameter comprises a Gamma band;

and/or,

the grayscale parameter comprises a grayscale value of a color corresponding to the first image.

5 . The apparatus according to claim 4 , wherein the processor is configured to adjust a relation between the grayscale parameter and the compensation value according to the adjustment value, wherein the compensation value is determined based on a grayscale compensation value, a brightness correction coefficient, and a grayscale correction coefficient;

adjust a first relation table between the grayscale compensation value and a life attenuation value, a second relation table between the brightness correction coefficient and the brightness parameter, and a third relation table between the grayscale correction coefficient and the grayscale parameter according to the adjusted relation; and

adjust the parameter in the preset model according to the adjusted first relation table, second relation table and third relation table.

6 . The apparatus according to claim 1 , wherein the processor is configured to, when the life attenuation value of the first area is greater than a first attenuation threshold, compensate the first area with a first compensation value calculated by the preset model; and/or,

when the life attenuation value of the second area is greater than a second life attenuation threshold, compensate the second area with a second compensation value calculated by the preset model.

7 . A model adjustment method, performed by a display panel, wherein the display panel at least comprises a first area and a second area, a life attenuation value of the first area is greater than a life attenuation value of the second area, and the method comprises:

displaying a first image;

compensating brightness of at least one of the first area or the second area in the first image according to a compensation value calculated by a preset model;

receiving an adjustment value from a user for the compensation value; and

adjusting a parameter in the preset model according to the adjustment value;

wherein the method further comprises:

displaying at least one of a brightness parameter or a grayscale parameter corresponding to the first image when displaying the first image;

wherein the method further comprises:

displaying an adjusted first image according to an adjustment of at least one of the brightness parameter or the grayscale parameter by the user;

wherein the method further comprises:

compensating, after each time the first image is adjusted, the brightness of at least one of the first area or the second area in the adjusted first image according to the compensation value calculated by the preset model;

receiving respective adjustment value from the user for a respective compensation value calculated by the preset model each time; and

wherein adjusting the parameter in the preset model according to the adjustment value comprises:

adjusting the parameter in the preset model according to adjustment values received in multiple times.

8 . The method according to claim 7 , wherein the display panel comprises an organic light emitting diode display panel.

9 . The method according to claim 8 , wherein the first area is a non-rollable area, and the second area is a rollable area.

10 . The method according to claim 7 , wherein the brightness parameter comprises a Gamma band;

and/or,

the grayscale parameter comprises a grayscale value of a color corresponding to the first image.

11 . The method according to claim 10 , wherein adjusting the parameter in the preset model according to the adjustment value comprises:

adjusting a relation between grayscale and a correction value according to the adjustment value, wherein the correction value is determined based on a grayscale compensation value, a brightness correction coefficient, and a grayscale correction coefficient;

adjusting a first relation table between the grayscale compensation value and the life attenuation value, a second relation table between the brightness correction coefficient and the brightness value, and a third relation table between the grayscale correction coefficient and the grayscale value according to the adjusted relation; and

adjusting the parameter in the preset model according to the adjusted first relation table, second relation table and third relation table.

12 . The method according to claim 7 , wherein compensating brightness of at least one of the first area or the second area in the first image according to a compensation value calculated by a preset model comprises:

when the first life attenuation value is greater than a first attenuation threshold, compensating the first area with a first compensation value calculated by the preset model; and/or,

when the second life attenuation value is greater than a second life attenuation threshold, compensating the second area with a second compensation value calculated by the preset model.

13 . A non-transitory computer-readable storage medium, storing a computer program, wherein when the program is executed by a processor, the method according to claim 7 is implemented.
