Patent ID: 7742025

Claim:
A display apparatus comprising: a light emitting element; a driving transistor for the light emitting element; a first switching transistor coupled with the driving transistor to transmit a data voltage; and a second switching transistor coupled with the driving transistor to transmit a reverse voltage; a first pixel including the first switching transistor and the second switching transistor, and the first pixel emits light when the first switching transistor is turned on for a first time period; a second pixel including a third switching transistor and a fourth switching transistor, and the second pixel emits light when the third switching transistor is turned on for a second time period that is different from the first time period; a first group of scanning signal lines, a first scanning signal line in the first group of scanning signal lines is coupled with the first switching transistor, and a second scanning signal line in the first group of scanning signal lines is coupled with the fourth switching transistor; a second group of scanning signal lines, a first scanning signal line in the second group of scanning signal lines is coupled with the second switching transistor, and a second scanning signal line in the second group of scanning signal lines is coupled with the third switching transistor; a first scanning driver to sequentially apply a first voltage for turning on switching transistors coupled with scanning signal lines of the first group of scanning signal lines; and a second scanning driver to sequentially apply a second voltage for turning on the switching transistors coupled with scanning signal lines of the second group of scanning signal lines.
