Abstract

The invention provides an organic light-emitting display panel and a preparation method thereof. The organic light-emitting display panel comprises a display substrate, a touch structure layer and a polaroid; the polaroid is integrated on the display substrate or the touch structure layer; the polaroid comprises a retaining wall, a first orientation layer, a 1 / 4 lambda phase difference layer, a second orientation layer, a polarizing layer and a first protection layer, wherein the first orientation layer, the 1 / 4 lambda phase difference layer, the second orientation layer, the polarizing layerand the first protection layer are sequentially arranged. According to the organic light-emitting display panel, the polaroid is integrated on the display substrate or the touch structure layer by adopting an ink-jet printing process, so that the thickness of the polaroid is reduced, and therefore, the bending reliability of the organic light-emitting display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel. Background technique [0002] In dynamically bending OLED display panels, the reliability of bending is very important. At present, for the external hanging OLED display panel, the thickness of the polarizer and the adhesive layer is 300 microns, and its thickness accounts for nearly 1 / 4 of the display panel. However, due to the thick thickness of the polarizer and the adhesive layer, the bending reliability of the OLED display panel is relatively poor. Contents of the invention [0003] Embodiments of the present application provide an organic light emitting display panel and a manufacturing method thereof to solve the technical problem that the existing organic light emitting display panel cannot thin the thickness of the polarizer and the adhesive layer, resulting in poor bending reliability of the panel. [0004] An embodiment of the present ap...
