Abstract: A display apparatus and a pixel circuit thereof are provided. The pixel circuit is configured to drive a light-emitting diode (LED). The pixel circuit includes a driving transistor, a switch, a data writing circuit, and a voltage selector. The switch is turned on during a data-writing time period, and cut-off during a laser time period. The data writing circuit transports a data voltage to a control terminal of the driving transistor during the data-writing time period. During the data-writing time period, a second terminal of the LED receives a first reference voltage, and during the laser time period, the second terminal of the LED receives a second reference voltage. The first reference voltage and the second reference voltage are different.
