Abstract
The disclosure discloses a pixel compensation circuit, a method for driving the same, a display panel, and a display device. The pixel compensation circuit includes: a first initialization sub-circuit, a second initialization sub-circuit, an IR drop control sub-circuit, a data writing sub-circuit, a compensation sub-circuit, a driver sub-circuit, a light-emission control sub-circuit, and a light emitting element. The compensation sub-circuit compensates for threshold voltage of the driver sub-circuit, and the IR drop control sub-circuit decreases the influence of the IR drop of a signal of the high-level power supply terminal to the operating current of the light emitting element.
