Abstract
The disclosure discloses a display panel, a method for compensating for the same, and a display device. The display panel includes a primary driver chip and at least one slave driver chip, each of which includes a gamma circuit; a processing circuit; and signal collectors on respective driver chips, configured to acquire current voltage at corresponding binding points of respective gamma circuits. 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 current voltage at the corresponding binding points of the respective gamma circuits on the respective driver chips are same.
