Abstract

A micro light emitting diode display panel including a plurality of pixels and a control element is provided. One of the pixels include a first sub-pixel. The first sub-pixel includes two micro light emitting diodes having different light wavelengths and controlled independently. The control element controls driving currents to the two micro light emitting diodes according to a gray level of the first sub-pixel, wherein a ratio of the driving current of the micro light emitting diode with larger light wavelength to the driving current of the micro light emitting diode with smaller light wavelength increases as the gray level of the first sub-pixel increases. A driving method of the micro light emitting diode display panel is also provided.
