Abstract

The present application discloses an organic light-emitting diode display substrate and its preparation method, and a display device. The display substrate includes a substrate, and the substrate includes a light-emitting area and a non-light-emitting area; wherein, the light-emitting area includes a plurality of data lines arranged in rows and columns perpendicular to each other. And a plurality of scanning lines, and a plurality of pixel unit areas defined by a plurality of data lines and a plurality of scanning lines, each pixel unit area includes a plurality of sub-pixels, and each sub-pixel in an adjacent pixel unit area in the same column The scanning lines are merged between the adjacent pixel unit areas, and the data lines of the adjacent pixel unit areas in the same row are combined between the adjacent pixel unit areas. Through the above method, the present application can realize the maximization of the line width of the nano-silver wire, and at the same time can reduce the printing precision of the nano-silver wire and improve its printing yield.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an organic light emitting diode display substrate, a preparation method thereof, and a display device. Background technique [0002] Compared with liquid crystal display (LCD), Organic Light Emitting Diode (OLED) has the advantages of self-illumination, wide viewing angle, high brightness, low power consumption, light and thin, etc., and is considered to be the next generation display technology. [0003] Existing OLED devices generally include an anode and a cathode, and a light-emitting layer between the anode and cathode. According to different light emitting directions, it can be divided into two types: bottom-emitting devices and top-emitting devices. Because the top-emitting device can obtain a larger aperture ratio and can significantly improve the brightness of the screen, it has become a research hotspot in recent years. [0004] At present, the excessive ca...
