Display panel, method for compensating for the same, and display device

A display device, comprising a display panel, wherein the display panel comprises:

• driver chips comprising a primary driver chip and at least one slave driver chip;
• wherein each of the driver chips comprises a gamma circuit;
• a processing circuit;
• and
• signal collectors on respective driver chips;
• wherein the signal collectors are configured to acquire current voltage at corresponding binding points of respective gamma circuits on the respective driver chips, and to provide the current voltage to the processing circuit;
• and
• the processing circuit is configured to compare current voltage at corresponding binding points of respective gamma circuits on respective slave driver chips with current voltage at a corresponding binding point of a gamma circuit on the primary driver chip, and to compensate for voltage to be output at the corresponding binding points of the respective gamma circuits on the respective slave driver chips according to comparison results so that the current voltage at the corresponding binding points of the respective gamma circuits on the respective driver chips are same.
