Embodiment Construction

[0026] It can be seen from the background art that the display screen in the prior art has the problem of poor display effect.

[0027] refer to figure 1 , figure 1 It is a schematic diagram of a partial cross-sectional structure of an existing OLED display screen, and the OLED display screen includes: a thin film transistor (TFT, Thin Film Transistor) 10; a multilayer structure 20 located on the thin film transistor 10, the multilayer structure 20 includes an anode layer and An organic functional layer on the surface of the anode layer; a cathode layer 30 on the surface of the multilayer structure 20; an encapsulation layer 40 covering the cathode layer 30, the surface of the TFT 10 and the sidewall of the multilayer structure 20.

[0028] The inventors have found that during the dynamic bending process of the OLED display, the film layer is easily damaged in the bending area, which will lead to poor display effect or even display failure. The main reason is that the thin f...

Abstract

The present invention provides an OLED structure and its preparation method, a display panel and an electronic device. The OLED structure comprises: an array substrate, a first electrode located on one side of the array substrate, a plurality of light-emitting units, and pixel definitions spaced from the light-emitting units. layer, and a second electrode arranged opposite to the first electrode, the plurality of light emitting units correspond to the light emitting area of ​​the OLED structure, the pixel defining layer corresponds to the non-light emitting area of ​​the OLED structure, and also includes: auxiliary An electrode, the auxiliary electrode is located in the non-light-emitting area, and is electrically connected to the first electrode and / or the second electrode, and the material of the auxiliary electrode is a conductive fiber material. The auxiliary electrode has good conductivity and bending resistance, prevents circuit damage when the first electrode or the second electrode breaks, and improves electrode reliability of the OLED structure.

Description

technical field [0001] The embodiments of the present invention relate to the field of display, and in particular to an OLED structure and a manufacturing method thereof, a display panel and electronic equipment. Background technique [0002] OLED (Organic Light-Emitting Diode) is called an organic light-emitting diode. OLED display technology has many advantages such as full solid state, active light emission, high contrast, ultra-thin, low power consumption, fast effect speed, wide working range, easy realization of flexible display and 3D display, etc., making it widely used in many display devices at present. , for example on televisions and mobile devices. [0003] Flexible OLED refers to a flexible organic light emitting diode, which is manufactured based on a flexible substrate and operates on the flexible substrate. Compared with traditional rigid OLEDs, flexible OLEDs are more flexible, lighter and thinner, making foldable and rollable display technologies possibl...
