AI Technical Summary

Problems solved by technology

When the physical properties of organic materials change, the brightness of OLED will decline
Therefore, in some FOLEDs, a heat dissipation layer is provided to help dissipate heat. However, the method of disposing the heat dissipation layer for heat dissipation results in a decrease in the bending resistance of the FOLED.

Abstract

The invention provides a flexible display device. The flexible display device comprises a flexible display panel and a heat dissipation layer; the flexible display panel comprises a bending area and a non-bending area; the heat dissipation layer comprises a first heat dissipation sublayer and a second heat dissipation sublayer, the first heat dissipation sublayer is arranged on the non-bending area, and the second heat dissipation sublayer is arranged on the first heat dissipation sublayer. According to the flexible display device, the heat dissipation layer is arranged on the non-bending area of the flexible display panel, the heat dissipation performance of the flexible display device is improved, and the bending resistance of the flexible display device is also improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display device. Background technique [0002] Organic electroluminescent displays (OLEDs) have the advantages of self-luminescence, low power consumption, and fast response, and are widely used in the field of display technology. Among them, the flexible OLED (Flexible OLED, FOLED) with flexible materials as the substrate is widely used in the display screens of mobile phones and televisions due to its certain deformation tolerance and the characteristics of being able to be rolled up and folded. [0003] When the FOLED is working, batteries and IC (Integrated Circuit, integrated circuit) chips inside the mobile phone and TV will emit a lot of heat, which will affect the work of the FOLED. In the OLED manufacturing process, the organic film layer produced by thermal evaporation is non-crystalline. Because some organic materials used to make organic film layers have ...
