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.

Abstract: A multiplexer circuit includes a first switch unit and a second switch unit. The first switch unit is electrically connected to a first data line and a first pixel circuit, and configured to turn on according to a first signal in a first time duration. The second switch unit is electrically connected to the first data line and a second pixel circuit, and configured to turn on according to a second signal in a second time duration. The first time duration and the second time duration substantially start or end at a same time, so that the first time duration and the second time duration have overlap.
