Abstract

The invention relates to the technical field of display, and provides a micro light emitting diode chip, a manufacturing method thereof, and a display panel manufacturing method. The chip comprises adriving circuit layer and a micro light emitting diode layer. The driving circuit layer is arranged on a substrate and comprises a pixel driving circuit; and the micro light emitting diode layer is arranged on one side, deviating from the substrate, of the driving circuit layer, and comprises micro light-emitting diodes, wherein the pixel driving circuit is used for driving the micro light emitting diodes to emit light. The pixel driving circuit and the micro light emitting diodes of the micro light-emitting diode chip are arranged into an integrated structure, so that the micro light emittingdiode chip can be directly transferred to the substrate of a display panel, and the risk of poor bonding between the micro light emitting diodes and the pixel driving circuit when the micro light emitting diodes are independently transferred in related technologies is avoided. The micro light emitting diode chip also can detect the performances of the micro light emitting diodes in advance.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a micro light-emitting diode chip, a manufacturing method, and a display panel manufacturing method. Background technique [0002] Micro LED (Micro Light Emitting Diode, Micro Light Emitting Diode) is one of the hot spots of display technology. The size of the LED used in the Micro LED display panel can reach the micron level. The display panel has independent control of pixels, independent light emission control, high luminance , low power consumption, ultra-high resolution and high color saturation. [0003] In related technologies, the Micro LED display panel mainly bonds a single Micro LED device to a receiving substrate (usually a display panel) through mass transfer technology, so as to realize the connection between the Micro LED device and the pixel driving circuit on the receiving substrate. [0004] However, in the related art, the bonding process of the Micro LED dev...
