Abstract
Provided is a micro light emitting diode display panel, comprising a flexible substrate, light emitting diodes aligned in an array, a diffraction grating and a light scattering film arranged on the light emitting diodes and light valves arranged above the light scattering film; wherein the flexible substrate comprises a driving circuit, the light emitting diodes are fixed on the flexible substrate; the driving circuit is connected to the light emitting diodes to respectively drive the light emitting diodes to emit white light; the diffraction grating splits the white light emitted by the light emitting diodes to form exiting lights with various wavelengths; the light scattering film gathers an exiting light of a same wavelength in the exiting lights and disperses the exiting lights of different wavelengths to form a primary color light of at least one color; the light valves adjusts an intensity of the primary color light.
