Abstract

The invention provides a foldable display device, comprising a display panel and a support plate arranged on a backlight side of the display panel, wherein the support plate includes a folded area and an unfolded area, the folded area and the unfolded area are integrated without an interface, the folded area comprises a flexible portion, and the unfolded area comprises a rigid portion, the elastic modulus of which is greater than the elastic modulus of the flexible portion, therefore, the folded area has resistance to bending, and the unfolded area has relatively strong rigidity to achieve foldable display in a fixed area. The folded area and the unfolded area are integrated without the interface, so that cracking at the interface while bending is avoided.

Description

technical field

[0001] The invention relates to the field of foldable displays, in particular to a foldable display device. Background technique

[0002] With the continuous development of display technology, the display panel manufacturing technology is becoming more and more mature. Existing display panels mainly include Organic Light Emitting Diode (OLED), Liquid Crystal Display (LCD), A plasma display panel (Plasma Display Panel, PDP) and the like. Today, there is an ever-increasing public demand for portable devices (eg, mobile phones, tablets, etc.). Foldable display devices have the characteristics of easy portability and large-size screens. Therefore, the public shows great interest in foldable display devices.

[0003] Such as figure 1 As shown, in the existing display panel, in order to protect the display panel 10' from external scratches and impacts, a cover window 80' is provided on the upper surface, and a support mechanism 20' is provided on the lower surf...
