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 circuit includes a light-emitting device, a first transistor, a second transistor, a first capacitor, a third transistor, a fourth transistor, and a fifth transistor. The first transistor and the fourth transistor are controlled by a light-emitting signal. The third transistor and the fifth transistor are controlled by a scan signal. The light-emitting device, the first transistor, the second transistor, the fourth transistor, and the fifth transistor are serially connected between a system high voltage and a system low voltage. The third transistor is coupled between a data signal and a control terminal of the first transistor. The first capacitor is coupled between a control terminal and a downstream terminal of the second transistor. The fifth transistor is coupled between the downstream terminal of the second transistor and a charging reference voltage. A current of the charging reference voltage is less than a current of the system low voltage.
