Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0038] The flexible display device is composed of multi-layer structures. At room temperature such as 25°C, the flexible display device can be bent hundreds of thousands of times. However, at a low temperature such as below 0°C, the flexible display device will The number of folds is reduced to less than tens of thousands of times or even fails. The inventors have found through research that the decrease in the bending performance of the flexible display device at low temperature is due to the failure of materials...

Abstract

The embodiment of the invention discloses a display device. The display device includes an optical adhesive layer, the display device is divided into a bending area and a non-bending area, and a temperature detection device is arranged on the bending area and on the surface of the optical adhesive layer, and the temperature detection device is used to detect the optical adhesive in the bending area. The temperature of the layer, the controller, the controller is electrically connected to the temperature detection device, the controller is used to output the temperature adjustment control signal according to the temperature value detected by the temperature detection device, the controller and the temperature detection device are both arranged in the non-luminous area of ​​the display device, And the first heating layer arranged in the bending area, the first heating layer is electrically connected with the controller, and the first heating layer is used to adjust the temperature of the optical adhesive layer in the bending area according to the temperature regulation control signal. The technical solution provided by the embodiments of the present invention solves the problem of lower bending performance of the existing display device at low temperature.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of display panels, and in particular, to a display device. Background technique [0002] With the development of display technology and the improvement of people's living standards, display devices are widely used.
