Abstract

A flexible display device includes a display region, a bending region, and a driving circuit board, wherein the bending region is positioned between the display region and the driving circuit board, and the driving circuit board is positioned on a back side of the display region by bending at the bending region, wherein the bending region includes a substrate; An inorganic layer disposed on the substrate, wherein the inorganic layer is distributed in an island shape on the substrate and includes a plurality of island-shaped blocks, wherein two adjacent island-shaped blocks are spaced apart from each other; And a first metal layer disposed over the entire surface of the inorganic layer and the substrate, wherein the first metal layer forms a plurality of first grooves corresponding to the shapes of the plurality of island-shaped blocks.

Description

technical field [0001] The disclosure relates to the field of display devices, in particular to a flexible display device and a manufacturing method thereof. Background technique [0002] Compared with traditional liquid crystal displays, flexible organic electroluminescent displays (OLEDs) have many advantages such as bendability, active light emission, high contrast, thinness, and fast response. Therefore, in recent years, OLED technology has received more and more attention, and people have higher and higher requirements for its performance, such as researching technologies such as narrow borders and full screens. [0003] Generally speaking, an OLED device is mainly composed of a display area (Display Area), a wiring area (Fanout), a bending area (Bending), a driving circuit board (FPC), etc., and the bending area is mainly used to connect the peripheral wiring area. The metal wires on the top and the driving circuit board are bent so that the driving circuit board can ...
