Abstract

The present disclosure describes a dual-cell display apparatus. The apparatus includes a first panel, and a second panel disposed in a first preset order relative to the first panel. The apparatus includes a memory storing instructions; and a processor in communication with the memory. When executing the instructions, the processor is configured to receive an image signal, and generate dimming data for the first panel according to the image signal. When executing the instructions, the processor is also configured to generate image data for the second panel according to the image signal, and generate backlight data for backlight control according to the image signal.

Claims (61)

1. A dual-cell display apparatus, comprising:

a first panel;

a second panel disposed in a first preset order relative to the first panel;

a memory storing instructions; and

receive an image signal,

generate dimming data for the first panel according to the received image signal, and perform edge blurring processing before outputting the dimming data,

generate image data for the second panel according to the received image signal, and

generate backlight data for backlight control according to the received image signal.

2. The dual-cell display apparatus according to claim 1 , wherein, when executing the instructions, the processor is configured to perform resolution reduction processing for the received image signal.

3. The dual-cell display apparatus according to claim 1 , further comprising:

a backlight module, comprising a plurality of backlight partitions.

4. The dual-cell display apparatus according to claim 3 , further comprising:

a backlight control processor configured to generate control information for controlling the backlight module according to the backlight data; and

a backlight driver configured to drive a backlight lamp on the backlight module according to the control information.

5. The dual-cell display apparatus according to claim 4 , wherein the backlight control processor is further configured to:

determine a backlight gain value according to an average backlight value of the plurality of backlight partitions; and

generate the control information according to the backlight gain value.

6. The dual-cell display apparatus according to claim 4 , wherein the backlight control processor is further configured to:

divide the plurality of backlight partitions into a plurality of backlight regions;

determine a backlight gain value according to an average backlight value of each of the plurality of backlight regions; and

generate the control information according to each backlight gain value.

7. The dual-cell display apparatus according to claim 1 , wherein, when executing the instructions, the processor is configured to:

generate the backlight data for the backlight control according to the dimming data.

8. The dual-cell display apparatus according to claim 7 , wherein, when executing the instructions, the processor is configured to:

generate the backlight data for the backlight control by performing resolution reduction processing and time filtering processing for the dimming data.

9. The dual-cell display apparatus according to claim 1 , wherein, when executing the instructions, the processor is configured to:

generate the image data for the second panel by performing image compensation processing according to the dimming data.

10. The dual-cell display apparatus according to claim 1 , wherein:

the first panel comprises a first polarizer and a second polarizer, a polarization direction of the first polarizer and a polarization direction of the second polarizer are perpendicular to each other; and

the second panel comprises a third polarizer and a fourth polarizer, a polarization direction of the third polarizer and the polarization direction of the second polarizer are parallel to each other, and the polarization direction of the third polarizer and a polarization direction of the fourth polarizer are perpendicular to each other.

11. The dual-cell display apparatus according to claim 1 , wherein:

receive an image signal,

generate dimming data for the first panel according to the received image signal,

generate image data for the second panel according to the received image signal, and

generate backlight data for backlight control according to the received image signal; and

wherein the second panel is further configured to:

receive a color drive signal; and

adjust an RGB value of a pixel of the second panel according to the color drive signal.

14. A dual-cell display apparatus, comprising:

a first panel;

a second panel disposed in a first preset order relative to the first panel;

a memory storing instructions;

a processor in communication with the memory, wherein, when executing the instructions, the processor is configured to:

receive an image signal,
