Abstract
The present application provides a pixel compensation circuit, a method for driving the same, and a display apparatus. The pixel compensation circuit includes a light emitting element, a current control sub-circuit and a reverse bias sub-circuit. The current control sub-circuit is coupled to a first terminal of the light emitting element and is configured to control current flowing between a first terminal and a second terminal of the light emitting element. The reverse bias sub-circuit is coupled to a first control signal line and a second terminal of the light emitting element respectively. The reverse bias sub-circuit is configured to set the second terminal of the light emitting element to be at a first bias voltage under the control of a signal on the first control signal line, so that the light emitting element is maintained in a reverse bias state.
