Display panel, code reading method and computer readable storage medium

A display panel, wherein, the display panel comprises a memory, a timing controller, and at least one processor, default codes, a backup codes identical to the default codes, and computer executable instructions executable by at least one processor are stored in the memory, in determination that the computer executable instructions are executed by the at least one processor, one processor is caused to perform the following steps:

• reading the default codes of the storage area, by the timing controller, in determination that the timing controller is powered on;
• determining whether the default codes are rewritten or not;
• reading the backup codes of the storage area to take the backup codes as the target codes in determination that the default codes are rewritten;
• and
• taking the default codes as the target codes in determination that there is no rewriting of the default codes.

A computer readable storage medium, wherein the computer readable storage medium has computer executable instructions executable by at least one processor, the computer executable instructions, in determination that the computer executable instructions are executed by the at least one processor, one processor is caused to perform the steps:

• reading the default codes of the storage area, by the timing controller, in determination that the timing controller is powered on;
• determining whether the default codes are rewritten or not;
• reading the backup codes of the storage area to take the backup codes as the target codes in responding to a determination that the default codes are rewritten;
• and
• taking the default codes as the target codes in responding to a determination that there is no rewriting of the default codes.
