Problems solved by technology

[0003] Among them, the Micro LED display integrates the technical characteristics of TFT-LCD (thin film transistor-liquid crystal display, thin film transistor liquid crystal display) and LED display. Then transfer the Micro LED from the initial growth substrate to the circuit substrate. One of the difficulties in the development of Micro LED technology lies in the transfer process of Micro LED. Currently, the process of transferring Micro LED chips to the circuit substrate is complicated.

Abstract

The invention discloses a Micro LED display panel, a manufacturing method thereof and a display device. It is only required to press an LED chip array into a bonding film layer when the LED chip arrayis transferred, the LED chip array is bonded onto a bearing substrate or an array substrate via the bonding film layer, and an unnecessary part of the bonding film layer is removed to remove unnecessary LED chips and thus complete transfer. All chips in the LED chip array are welded to the substrate one by one needless of a welding manner, The Micro LED display panel manufacturing technology is simplified, the technical difficulty of the Micro LED display panel is reduced, influence of high temperature of the welding technology on the LED chip is avoided, and the LED chips are avoided from damage in the transfer process.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a Micro LED display panel, a manufacturing method thereof, and a display device. Background technique [0002] Light Emitting Diode (LED) is an optoelectronic semiconductor element that can convert current into a specific wavelength range. Its light-emitting principle is the energy difference between electrons moving between n-type semiconductors and p-type semiconductors, releasing energy in the form of light , so light-emitting diodes are called cold light sources, which have the advantages of low power consumption, small size, high brightness, easy matching with integrated circuits, and high reliability, and are widely used as light sources. Moreover, with the maturity of LED technology, the technology of directly using LEDs as self-luminous display dot pixels of LED displays or Micro LED (ie, micro LED) displays is gradually being widely used.
