Abstract
The present disclosure relates to a pixel circuit and a method for driving the same. The pixel circuit includes: first and second transistors, control terminals of which receive a first scan signal; third and fourth transistors, control terminals of which receive a second scan signal; a fifth transistor, a control terminal of which is electrically coupled to a capacitor; sixth, seventh and eighth transistors, control terminals of which receive a control signal; and a light emitting diode. The present disclosure can reduce or reversely compensate the current leakage, and thus the holding capability of the capacitor can be enhanced. Consequently, the image flicker and thereby the image reliability can be improved.
