Problems solved by technology

[0006] This differential force situation will make the outer metal wire in the double-layer metal wire, compared with the inner metal wire, due to the greater force, resulting in poorer stability than the inner metal wire
Furthermore, the difference in the stability of the metal wires will affect the stability of the subsequent display products to a certain extent. Can connect stably

Abstract

The invention provides a display device which comprises a display panel and a flexible substrate. A bending area is defined on the flexible substrate, and comprises a first layer and a second layer inthe vertical direction. When the bending area is bent, the first layer is located on the outer layer, and the second layer is located on the inner side of the first layer. The first layer is internally provided with a first metal wire of the first shape. The second layer is internally provided with a second metal wire of the second shape. The length of the first metal wire is larger than the length of the second metal wire. According to the display device, the brand-new dual-layer metal wire shape structure design is adopted for the flexible substrate, the intensity of stress borne by the metal wire on the outer layer of the bending area is effectively improved, the metal wires of the inner layer and the outer layer in the bending area both bear force evenly, and the stability of the metal wires is consistent.

Description

technical field [0001] The present invention relates to the technical field of plane display, in particular, a display device therein. Background technique [0002] It is known that liquid crystal display screen or OLED display screen has been widely used and generally accepted by the market due to its lightness, thinness, good display effect and other advantages. [0003] With the development of mobile phones in the direction of high screen-to-body ratio and high resolution, the narrow border design of the display screen has become a trend in the development of mobile phone structures. In this regard, the industry generally adopts Pad Bending technology to realize this narrow bezel design. [0004] For example, see Figure 4 As shown in , it illustrates a common pad bending structure in display devices. Wherein the flexible substrate 100 is provided with a metal line (metal line) 102 for electrically connecting the display panel 110 and the PCB board 120 . Among them, th...
