Problems solved by technology

[0004] However, in the above-mentioned flexible electroluminescent device, due to the poor flex resistance and fatigue resistance of the nano-silver wire 10, and the toughness is also poor, the nano-silver wire 10 will be damaged by repeated stretching, bending and other deformations of the flexible electroluminescent device. Line 10 is prone to thinning or breaking
The thinning or breaking of the nano-silver wire 10 greatly increases the impedance of the patterned cathode layer, thereby causing a change in the conductivity of the flexible electroluminescent device, which in turn leads to uneven display of the LED flexible display device and affects the quality of the LED flexible display device and lifespan

Abstract

The present invention provides a flexible electroluminescent device and a preparation method thereof, and a flexible display device. The flexible electroluminescent device comprises a flexible graphical cathode layer provided with a flexible film, and the flexible film comprises a graphical groove internally provided with carton materials. The flexible electroluminescent device and the preparationmethod thereof, and the flexible display device can meet the flexible characteristic requirements of the flexible electroluminescent device and have good flexibility resistance, fatigue durability and toughness, the conductivity is slightly changed with increasing of the elongation, the flexible electroluminescent device can effectively stabilize the conductivity in the flexible deformation process, and therefore, it is avoided that the display of the flexible display device is not uniform caused by change of the conductivity of the flexible graphical cathode layer.

Description

technical field [0001] The present application relates to the technical field of flexible display, in particular to a flexible electroluminescence device, a preparation method thereof and a flexible display device. Background technique [0002] With its advantages of high efficiency, stability, reliability, and long life, LED display devices are widely used in various places and become the main tool for public information dissemination. The miniaturization of LED light-emitting tubes has led to a rapid increase in the resolution of LED display devices. Combining with the current trend of high-definition video, the application fields of LED display devices have become wider and wider. With the development and demand of display screens, due to the advantages of strong portability and rich application scenarios of flexible display screens, LED flexible display devices have begun to appear on the market. [0003] Flexible electroluminescent devices are the main light-emitting d...
