Abstract: A pixel array is provided. The pixel array includes a plurality of red pixels, a plurality of green pixels, and a plurality of blue pixels. Each green pixel includes a light emitting diode (LED), a first transistor, a second transistor, a third transistor, and a fourth transistor. The LED receives a system low voltage. The first transistor receives a first data signal and a first scan signal. The second transistor is coupled to a second end of the first transistor and the anode of the light emitting diode. The third transistor receives a system high voltage and a first control signal, and is coupled to a first end of the second transistor. The fourth transistor is coupled to the anode of the light-emitting diode of an adjacent green pixel, a control terminal of the third transistor, and the anode of the light-emitting diode.

Abstract: A pixel array is provided. The pixel array includes a plurality of pixels, wherein each of the pixels includes a light emitting diode, a first transistor, a second transistor, a third transistor, a fourth transistor, and a fifth transistor. The first transistor receives a first data signal and a first scan signal. The second transistor is coupled to the first transistor and an anode of the light emitting diode. The third transistor receives a system high voltage and a first control signal, and is coupled to the second transistor. The fourth transistor is coupled to an anode of a light emitting diode of an adjacent pixel, a control terminal of the third transistor, and a cathode of the light emitting diode. The fifth transistor is coupled to the cathode of the light emitting diode, and receives a second control signal and a system low voltage.
