Abstract
Embodiments of pixel circuits for light emitting elements are disclosed herein. In one example, a pixel circuit includes a pixel driver configured to receive a data signal and drive a light emitting element based on the data signal, a first power signal coupled to an anode of the light emitting element through the pixel driver, and a second power signal coupled to a cathode of the light emitting element. In some embodiments, the second power signal is configured to vary based on the data signal. In some embodiments, in a first period of the data signal, a value of the second power signal is configured to be lower than a value of first power signal, and in a second period of the data signal, the value of the second power signal is configured to be higher than the value of the first power signal.
