Title
(EN) OLED (organic light emitting diode) display substrate, manufacture method thereof and display device
(ZH) OLED显示基板及其制作方法、显示装置
Abstract
(EN)
The invention provides an OLED (organic light emitting diode) display substrate, a manufacture method thereof and a display device, and belongs to the technical field of display. The manufacture method of the OLED display substrate includes the steps: forming an inverted table-shaped structure enclosing a cutting area on the periphery of the cutting area of the OLED display substrate; forming a reflective graphic between the inverted table-shaped structure and a base plate of the OLED display substrate before forming the inverted table-shaped structure. When a cathode of the OLED display substrate is formed, the edge of the cathode on the upper surface of the inverted table-shaped structure naturally fractures. The orthographic projection of the inverted table-shaped structure on the baseplate is positioned in the orthographic projection of the reflective graphic on the base plate. The packaging effect of the OLED display substrate can be ensured, and the performance of the display device is further ensured.
