Display apparatus and driving method thereof

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;
• 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,
• wherein the first switching transistor and the second switching transistor are turned on at different times.
