Embodiment Construction

[0029] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0030] The inventors of the present invention have found through research that the main reason for the poor bending reliability of the display panel in the prior art is: after repeated bending or bending at a large angle, the anode material in the display panel is relatively brittle, and ...

Abstract

The invention relates to a display panel. It includes: a flexible substrate, a driving layer group, formed on the flexible substrate; a planarization layer, located on the side of the driving layer group away from the flexible substrate; and an OLED layer group, located on the side of the planarization layer away from the flexible substrate ; Wherein, the material of the planarization layer is an elastomer material. The above-mentioned display panel uses the elastomer material as the planarization layer. When the display panel is bent, the elastomer material can effectively absorb the stress of the anode on it, thereby avoiding stress concentration on the anode, thereby effectively protecting the anode and preventing the anode from breaking or cracking, thereby improving the bending reliability of the display panel. The present invention also provides a method for preparing the above display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a preparation method thereof. Background technique [0002] AMOLED (Active-matrix organic light-emitting diode, active-matrix organic light-emitting diode) display panel has been widely used due to its low driving voltage and long life of light-emitting elements, and has gradually become a research and development hotspot in recent years. [0003] At present, a display panel generally includes a flexible substrate, a driving layer group, and an OLED layer group; wherein, the driving layer group is used to form a driving circuit structure for driving the OLED, and then control the OLED devices in the OLED layer group. An OLED layer group generally includes an anode, a cathode, and an organic functional layer between the anode and the cathode. The anode material is generally composed of ITO or the like. [0004] The above-mentioned display panel, after being ...
