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.

Pixel driving circuit and micro display panel

A micro LED display device in which each pixel unit of the display panel includes a first display pixel and a second display pixel. The first display pixel includes a first subpixel, a second subpixel and a third subpixel, and the second display pixel includes a fourth subpixel, a fifth subpixel and a sixth subpixel. The peak wavelength of fourth subpixel is less than that of first subpixel, and the peak wavelength of fifth subpixel is greater than that of second subpixel, so that at the same radiance, the luminance of second display pixel is greater than that of first display pixel, and the range of color gamut of first display pixel is greater than that of second display pixel. The control unit controls the driving unit to selectively drive the first display pixels or the second display pixels of the pixel units.
