Abstract

The invention discloses a foldable display panel and a foldable display device. The foldable display panel includes: a flexible base; a flexible display device disposed on the first side of the flexible base; a flexible heat conduction layer disposed on the second side of the flexible base and attached to the second side surface of the flexible base; disposed on the flexible heat conduction layer away from A supporting structure on one side of the flexible substrate, wherein the foldable display panel includes a bending area and a non-bending area, and the supporting structure is only arranged in the non-bending area; wherein, the thermal conductivity of the flexible heat-conducting layer is higher than that of the flexible base and the supporting structure thermal conductivity. The flexible heat conduction layer provided in the foldable display panel provided by the present invention is directly in contact with the flexible substrate, which can quickly conduct heat and uniformize the temperature on the flexible display panel, and reduce the risk of obvious bright or dark stripes on the display panel , ensuring uniform brightness of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a foldable display panel and a foldable display device. Background technique [0002] Organic Light-Emitting Diodes (Olganic Light-Emitting Diodes, OLED) is a device that can emit light automatically after being energized. It has the advantages of wide viewing angle, high contrast, low energy consumption, etc. The characteristics of bending performance make it one of the best choices for making foldable display devices. [0003] In the existing foldable display devices, the display panel is usually divided into a bending area and a non-bending area. Usually, a rigid structural support is provided in the non-bending area of ​​the display panel, but there is no rigid support in the bending area, and it can be bent at will. , so that the display device can be folded. In the existing foldable display devices using OLED as the display device, the OLED display devic...
