Abstract

The present invention discloses an OLED display screen, a display panel, and a manufacturing method thereof. The method comprises: forming, on a TFT array substrate, a high-resistance metal wire thatis parallel to an auxiliary electrode and has a spacing less than a threshold; after forming an EL layer of an OLED device, applying voltage to both ends of the high-resistance metal wire, to enable the high-resistance metal wire to generate heat; and after the heat makes a temperature of the auxiliary electrode rise, and makes a organic material of the high-resistance metal wire and the EL layeron the top of the auxiliary electrode evaporated and eliminated, depositing a transparent metal oxide to form a light-exiting surface electrode of the OLED device electrically connected to the auxiliary electrode. According to the manufacturing method, when a technique of connecting the light-exiting surface electrode of the OLED and the auxiliary electrode in a manufacturing process is performed,a punching operation is no longer needed, so that a process manufacturing time is shortened, and production efficiency is improved. Further, production costs may be further reduced because a high-precision laser puncher is not needed.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display screen, a display panel and a manufacturing method thereof. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display devices have become the first choice for high-end mobile phones, TVs, watches and other electronic devices due to their thinness, bright colors, and flexibility. In the future, there will also be An increasingly wide range of applications. Currently commonly used OLED device structures include top-emission and bottom-emission structures. Due to the advantages of high aperture ratio, the top-emission structure has gradually become the mainstream device structure of current display devices under the trend of gradually improving pixel resolution. [0003] However, OLED top-emitting devices also have certain technical difficulties. One of them is that the top-emitting device requires high transparency and...
