Abstract

The invention discloses a preparation method of an OLED and LED hybrid display panel and the display panel. The preparation method of the display panel comprises steps of forming an LED electrode, a first lap joint electrode and a second lap joint electrode on a driving back plate, forming a pixel definition layer, and exposing the LED electrode, one part of the first lap joint electrode and one part of the second lap joint electrode; forming a first reflection electrode in the green sub-pixel region on the surface of one side, far away from the driving back plate, of the pixel definition layer, forming a second reflection electrode and an optical adjustment layer in the red sub-pixel region, and forming a third reflection electrode in the blue sub-pixel region on the side surface, connected with the LED electrode, of the pixel definition layer; transferring the blue-light LED chip to a driving back plate and correspondingly and electrically connecting the blue-light LED chip with theLED electrode; and forming a green light organic light emitting device and a red light organic light emitting device. The method is advantaged in that the optical crosstalk of a blue-light LED chip isreduced.

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-LED 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. However, in the existing Micro-LED colorization scheme, the optical crosstalk phenomenon of the blue LED chip is relatively serious. Contents of the invention [0004] In view of this, the object of the present invention is to provide a method for preparing an OLED-LED hybrid display panel and the display panel, which reduce the o...
