Abstract

The invention provides an OLED display substrate, a display panel and a fabrication method of the display panel, and belongs to the technical field. By the OLED display substrate, the display panel and the fabrication method of the display panel, the problem that a traditional flexible OLED display substrate cannot be attached onto a cover plate with arc frames at four sides can be solved. In theOLED display substrate, a substrate material of a corner display region is a flexible material, a plurality of openings are formed in the substrate of the corner display region, thus, no wrinkle is generated on the OLED display substrate even being extruded due to the openings during the subsequent lamination process of the OLED display substrate and the cover plate, and display also cannot be affected due to the positions of the openings avoided by display components. The OLED display substrate is applicable to various display panels and is particularly applicable to a curve-surface display panel.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an OLED display substrate, a display panel and a preparation method thereof. Background technique [0002] Organic light emitting diode (Organic Light Emitting Diode, OLED) devices have self-illumination characteristics, which do not need to use a separate light source, so OLED display devices can be designed to be thinner and lighter, and are favored by the industry. If flexible materials are used as substrates in OLED display panels, products can be used in more ways: for example, borderless mobile phones can be realized, folding products, curly products can be designed, and so on. [0003] The birth of the flexible OLED display substrate provides a great help for the implementation of the design concept of the full screen. Specifically, a curved 3D (three-dimensional) cover (or 3D curved cover) and a flexible OLED display can be used. The bonding of the substrate...
