Abstract

The invention provides a MicroLED display panel and a forming method thereof. The display panel comprises a driving wafer, a MicroLED chip unit and a micro lens array, wherein the driving wafer is bonded with the MicroLED chip unit, the micro lens array comprises micro lenses which are distributed in an array, the micro lenses are hemispherical, and one side of the spherical surface of each micro lens faces the MicroLED chip unit. Therefore, light beams emitted by the MicroLED chip unit irradiate the spherical surface of the micro lens and are converged after being refracted, and better optical matching between the MicroLED chip unit and the micro lens array is realized, so that the light extraction efficiency is improved, the focusing of emergent light rays is more concentrated, the image display is clearer, and the light extraction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of integrated circuit manufacturing, and in particular relates to a Micro LED display panel and a forming method thereof. Background technique [0002] Micro LED (Micro light emitting diode) display is a next-generation display technology emerging after liquid crystal display and OLED display. Micro LED displays use LED light-emitting chips (Micro LED chips) with a size ranging from a few microns to tens of microns as pixel units, which are closely arranged in an array, and each chip can be independently driven to light up and emit light. MicroLEDs (also known as MicroLEDs, mLEDs or μLEDs). [0003] The optical matching of the current Micro LED display panel is not good, the light extraction efficiency of the display panel is not ideal, and the light extraction efficiency needs to be further improved. Contents of the invention [0004] The purpose of the present invention is to provide a MicroLED display...
