Abstract

The invention discloses a preparation method of an OLED hybrid display panel, and the display panel. The preparation method of the display panel comprises the steps: forming an LED electrode, a firstlap joint electrode and a second lap joint electrode on a driving backboard; transferring a blue-light LED chip to the driving backboard and correspondingly and electrically connecting the blue-lightLED chip with a LED electrode, wherein the blue-light LED chip is of a vertical structure; forming a pixel definition layer to expose the blue light LED chip, a part of the first lap joint electrode and a part of the second lap joint electrode; forming a first reflection electrode in a green sub-pixel region on the surface of one side, far away from the driving backboard, of the pixel definition layer, forming a second reflection electrode and an optical adjustment layer in a red sub-pixel area, and forming an LED negative electrode on a blue light LED chip, wherein the LED negative electrodeand an optical adjustment layer are located on the same layer, and the LED electrode comprises an LED positive electrode; and forming a green light organic light emitting device and a red light organic light emitting device. According to the technical scheme provided by the embodiment of the invention, the heat dissipation performance of the display panel is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular to a method for preparing an OLED hybrid display panel and the display panel. Background technique [0002] Micro-LED display technology has the advantages of low power consumption, high brightness, high color saturation, fast response, long life and high efficiency, and is considered to be the most competitive next-generation display technology. [0003] In the Micro-LED colorization solution, mass transfer technology is generally used to transfer millions or even tens of millions of LED chips to the driver backplane. Since the LED chip generates a certain amount of heat during operation, the heat dissipation performance of the existing Micro-LED color display panel is not good. Contents of the invention [0004] In view of this, the object of the present invention is to provide a method for preparing an OLED hybrid display panel and the display pa...
