Abstract
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.
