Abstract

Claims (38)

1. A display effect enhancement apparatus comprising:

a first demura module located in a main control chip and configured to perform a first brightness compensation on a picture to be displayed according to a grayscale value of each pixel of the picture;

a second demura module located in a driving chip and configured to perform a second brightness compensation on the picture to be displayed that has been subjected to the first brightness compensation; and

a display module configured to display the picture to be displayed that has been subjected to the second brightness compensation;

wherein the first demura module is configured to:

determine a target pixel and a non-target pixel in the picture to be displayed according to the grayscale value of each pixel and a preset rule;

perform brightness compensation on the target pixel based on a brightness compensation value corresponding to the target pixel, and perform brightness compensation on the non-target pixel based on a brightness compensation value corresponding to the non-target pixel, wherein the brightness compensation value corresponding to the target pixel is non-zero, and the brightness compensation value corresponding to the non-target pixel is zero; and

determine the preset rule according to a first compensation effect when the first demura module and the second demura module are turned on at the same time and a second compensation effect when only the second demura module is turned on.

2. A display effect enhancement method comprising:

obtaining a grayscale value of each pixel of a picture to be displayed;

performing a first brightness compensation on the picture to be displayed according to the grayscale value of each pixel through a first demura module in a main control chip;

performing a second brightness compensation on the picture to be displayed that has been subjected to the first brightness compensation through a second demura module in a driving chip; and

displaying the picture to be displayed that has been subjected to the second brightness compensation;

wherein performing a first brightness compensation on the picture to be displayed according to the grayscale value of each pixel comprises:

determining a target pixel and a non-target pixel in the picture to be displayed according to the grayscale value of each pixel and a preset rule;

performing brightness compensation on the target pixel based on a brightness compensation value corresponding to the target pixel, and performing brightness compensation on the non-target pixel based on a brightness compensation value corresponding to the non-target pixel, wherein the brightness compensation value corresponding to the target pixel is non-zero, and the brightness compensation value corresponding to the non-target pixel is 0; and

determining the preset rule according to a first compensation effect when the first demura module and the second demura module are turned on at the same time and a second compensation effect when only the second demura module is turned on.

3. The display effect enhancement method according to claim 2 , wherein determining the preset rule comprises:

using the second demura module to perform demura on a plurality of grayscale pictures or a picture comprising a plurality of grayscales so as to obtain a first demura image comprising the plurality of the grayscales;

using the first demura module to perform demura on the first demura image again so as to obtain a second demura image comprising the plurality of the grayscales; and

determining with the preset rule that the pixel corresponding to the grayscale is the target pixel if a display effect of the second demura image is better than that of the first demura image under the same grayscale, otherwise, the pixel corresponding to the grayscale is the non-target pixel.

4. A display effect enhancement device, comprising a processor, a memory, and a display effect enhancement program stored on the memory and executable by the processor, wherein when the display effect enhancement program is executed by the processor, the steps of the display effect enhancement method are realized according to claim 3 .

5. A display effect enhancement device, comprising a processor, a memory, and a display effect enhancement program stored on the memory and executable by the processor, wherein when the display effect enhancement program is executed by the processor, the steps of the display effect enhancement method are realized according to claim 2 .

6. A display effect enhancement method comprising:

obtaining a grayscale value of each pixel of a picture to be displayed;

judging whether to turn on a first demura module according to the grayscale value of each pixel and a preset rule, and performing a brightness compensation on the picture to be displayed based on a judgment value, wherein the preset rule is determined according to a first compensation effect when the first demura module and a second demura module are turned on at the same time and a second compensation effect when only the second demura module is turned on, the first demura module is located in a main control chip, and the second demura module is located in a driving chip; and

displaying the picture to be displayed that has been subjected to the brightness compensation.

7. The display effect enhancement method according to claim 6 , wherein judging whether to turn on the first demura module according to the grayscale value of each pixel and the preset rule, and performing brightness compensation on the picture to be displayed based on the judgment value comprise:

determining a target pixel and a non-target pixel in the picture to be displayed according to the grayscale value of each pixel and the preset rule;

turning on the first demura module and the second demura module and performing a second brightness compensation on the target pixel; and

turning off the first demura module, turning on the second demura module and performing a first brightness compensation on the non-target pixel.

8. The display effect enhancement method according to claim 7 , wherein determining the preset rule comprise:

using the second demura module to perform demura on a plurality of grayscale pictures or a picture comprising a plurality of grayscales so as to obtain a first demura image comprising the plurality of the grayscales;

using the first demura module to perform demura on the first demura image again so as to obtain a second demura image comprising the plurality of the grayscales; and

determining with the preset rule that the pixel corresponding to the grayscale is the target pixel if a display effect of the second demura image is better than that of the first demura image under the same grayscale, otherwise, the pixel corresponding to the grayscale is the non-target pixel.

9. A display effect enhancement device, comprising a processor, a memory, and a display effect enhancement program stored on the memory and executable by the processor, wherein when the display effect enhancement program is executed by the processor, the steps of the display effect enhancement method are realized according to claim 8 .

10. A display effect enhancement device, comprising a processor, a memory, and a display effect enhancement program stored on the memory and executable by the processor, wherein when the display effect enhancement program is executed by the processor, the steps of the display effect enhancement method are realized according to claim 7 .

11. A display effect enhancement device, comprising a processor, a memory, and a display effect enhancement program stored on the memory and executable by the processor, wherein when the display effect enhancement program is executed by the processor, the steps of the display effect enhancement method are realized according to claim 6 .
