Abstract

The invention provides a display device and a backboard thereof, and the backboard comprises: a flexible layer which is provided with a first surface and a second surface; a skeleton layer which is arranged on the first surface, wherein the skeleton layer comprises at least two skeleton strips, the skeleton strips are arranged at intervals, and the skeleton layer is made of a polymer; a filling layer which covers one side, far away from the flexible layer, of the skeleton layer, wherein the filling layer is embedded into a gap between every two adjacent skeleton strips. The display device andthe backboard thereof provided by the invention are used for solving the problem of corrugation of the backboard in the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and its backplane. Background technique [0002] Existing display devices mainly include organic light emitting diode (Organic Light Emitting Diode, OLED) display devices and liquid crystal display (Liquid Crystal Display, LCD) devices. With the increase in demand for flexible and foldable smartphones, and the development of foldable displays in tablets and wearable electronic devices, the development of flexible and foldable display panels has been stimulated. [0003] Currently, the OLED display device uses a backplane to support and protect the screen after being peeled off through a laser lift-off process. During the process of folding the screen, the inner surface of the back plate is compressed and deformed, and at the same time, it also exerts a pressing force on the adjacent film layer, resulting in ripples. [0004] Therefore, it is necessary ...
