Abstract

An application method of demura data having a uniform format includes: in step S 12 , it is determined whether demura data having a first format is stored in a first memory; if yes, step S 13 is performed; if no, step S 16 is performed; in step S 13 , it is checked whether the demura data having the first format is consistent with demura data having a second format and stored in a second memory; if yes, step S 14 is performed; if no, step S 16 is performed; in step S 14 , the demura data having the first format in the first memory is read; in step S 15 , a demura data compensation is activated; and in step S 16 , demura data having the first format is generated, according to the demura data having the second format and stored in the second memory, and stored; step S 15 is performed.

Claims (26)

1. An application method of demura data having a uniform format, comprising:

in step S 11 , a system chip is initialized;

in step S 12 , it is determined whether demura data having a first format is stored in a first memory; if yes, step S 13 is performed; if no, step S 16 is performed;

in step S 13 , it is checked whether the demura data having the first format is consistent with demura data having a second format and stored in a second memory; if the demura data having the first format is consistent with the demura data having the second format, step S 14 is performed; if the demura data having the first format is not consistent with the demura data having the second format, step S 16 is performed;

in step S 14 , the demura data having the first format in the first memory is read;

in step S 15 , a demura data compensation is activated; and

in step S 16 , demura data having the first format is generated, according to the demura data having the second format and stored in the second memory, and stored; step S 15 is performed.

2. The application method of the demura data having the uniform format of claim 1 , wherein step S 13 comprises:

in step S 131 , a cyclic redundancy check code of the demura data having the first format and stored in the first memory is read;

in step S 132 , a cyclic redundancy check code of the demura data having the second format and stored in the second memory is read; and

in step S 133 , a cyclic redundancy check is performed on the cyclic redundancy check codes read in steps S 131 and S 132 ; if the cyclic redundancy check code of the demura data having the first format is consistent with the cyclic redundancy check code of the demura data having the second format, step S 14 is performed; if the cyclic redundancy check code of the demura data having the first format is not consistent with the cyclic redundancy check code of the demura data having the second format, step S 16 is performed.

3. The application method of the demura data having the uniform format of claim 2 , wherein the system chip is a timing controller chip.

4. The application method of the demura data having the uniform format of claim 2 , wherein the system chip is a system on a chip (SoC).

5. The application method of the demura data having the uniform format of claim 1 , wherein step S 16 comprises:

in step S 161 , the demura data having the second format and stored in the second memory is read;

in step S 162 , demura information is extracted from the demura data having the second format;

in step S 163 , the demura information is written, in the first format, into the first memory, and the demura information is loaded into a register of the system chip; and

in step S 164 , the cyclic redundancy check code of the demura data having the second format is written into the first memory, and step S 15 is performed.

6. The application method of the demura data having the uniform format of claim 5 , wherein the system chip is a timing controller chip.

7. The application method of the demura data having the uniform format of claim 5 , wherein the system chip is a system on a chip (SoC).

8. The application method of the demura data having the uniform format of claim 1 , wherein the system chip is a timing controller chip.

9. The application method of the demura data having the uniform format of claim 8 , wherein the first memory is a memory on a control board, and the second memory is a memory on an X-board.

10. The application method of the demura data having the uniform format of claim 9 , wherein the memory on the control board is a flash memory, and the memory on the X-board is a flash memory.

11. The application method of the demura data having the uniform format of claim 1 , wherein the system chip is a system on a chip (SoC).

12. The application method of the demura data having the uniform format of claim 11 , wherein the first memory is a memory on the SoC, and the second memory is a memory on the X-board.

13. The application method of the demura data having the uniform format of claim 12 , wherein the memory on the SoC is an embedded multimedia card (eMMC), and the memory on the X-board is a flash memory.
