摘要： A micro LED display panel includes a driving substrate and a plurality of micro light emitting diodes (LEDs). The driving substrate has a plurality of pixel regions. Each of the pixel regions includes a plurality of sub-pixel regions. The micro LEDs are located on the driving substrate. At least one of the sub-pixel regions is provided with two micro LEDs of the micro LEDs electrically connected in series, and a dominant wavelength of the two micro LEDs is within a wavelength range of a specific color light. In a repaired sub-pixel region of the sub-pixel regions, only one of the two micro LEDs emits light. In a normal sub-pixel region of the sub-pixel regions, both of the two micro LEDs emit light.
