A driving circuit includes a first driving transistor and a second driving transistor. The first transistor has a first end to receive a power voltage, a control end of the first driving transistor receives a first control signal, and a second end of the first driving transistor is coupled to a light emitting component. The second transistor has a first end to receive a power voltage, a control end of the second driving transistor receives a second control signal, and a second end of the second driving transistor is coupled to the light emitting component. The first transistor provides a first driving current to the light emitting component according to the first control signal, and the second transistor provides a second driving current to the light emitting component according to the second control signal.

Driving circuit

A pixel driving circuit and a micro display panel are disclosed. A repair switch is in at least one sub-pixel circuit unit of each pixel driving circuit unit. A controlling unit controls the repair switch to turn on or off. When a micro-LED of the at least one sub-pixel, which the current flows through, illuminates during a non-driving period, the controlling unit controls the repair switch to interrupt the current. Therefore, the micro-LED of the at least one sub-pixel does not illuminate during the non-driving period and a light spot or light line issue is solved.
