Abstract

The invention discloses a transfer substrate, a manufacturing method thereof, and an OLED device manufacturing method, belonging to the field of displays. The transfer substrate is used for electrode thermal transfer of OLED devices, and the transfer substrate includes a light-transmitting substrate and a light-to-heat conversion layer; the light-to-heat conversion layer includes a plurality of protrusions arranged in an array, and the protrusions It includes a bottom surface and a top surface arranged in parallel, the bottom surface is arranged on the light-transmitting substrate, and each raised top surface is used for setting an electrode block to be transferred. Using the transfer substrate to realize OLED cathode production avoids the problem of serious damage to OLED organic thin film layers when the existing sputtering process produces a transparent cathode, thereby improving the performance and life of the device.

Description

technical field [0001] The invention relates to the field of displays, in particular to a transfer printing substrate, a manufacturing method thereof, and an OLED device manufacturing method. Background technique [0002] At present, commonly used displays mainly include two categories: Organic Light-Emitting Display (English, Organic Light-Emitting Display, OLED for short) and Liquid Crystal Display (English Liquid Crystal Display, LCD for short). Wherein, the OLED display panel mainly includes a base plate and a cover plate, the OLED light-emitting unit is arranged on the base plate, and the cover plate is covered above the OLED light-emitting unit on the base plate. The OLED light-emitting unit includes an anode, an organic thin film layer and a cathode formed sequentially on a substrate, and the organic thin film layer mainly includes a hole layer, an electron layer and a light-emitting layer between them. [0003] OLED can be divided into three types according to the d...
