Problems solved by technology

[0005] The display screen and display device provided by the present invention solve the problem of the existing display screen and display device. Since the surface of the bending part of the flexible substrate is a flat structure, when the metal traces on the surface are bent correspondingly, It is also a two-dimensional linear structure, which is prone to technical problems of disconnection due to excessive bending stress

Abstract

The invention provides a display screen and a display device. The display screen includes a display panel and a flexible substrate. The display panel includes a plurality of pads arranged adjacently. The flexible substrate includes a display part and a bending part. The first surface of the bending part There are a plurality of protrusions, and at least one metal trace is provided on the surface of each protrusion, and each metal trace is electrically connected to the corresponding pad; on the one hand, when the bending part is bent, the metal trace is attached to the The raised surface has a three-dimensional structure, thereby changing the bending angle of the metal traces, thereby reducing the tensile stress on the metal traces, and ensuring the stability of the connection between the display panel and the PCB board; on the other hand, it can increase the The length of the trace is such that when the metal trace is bent, the increased length can effectively compensate for the increased length required due to stretching.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display screen and a display device. Background technique [0002] Existing display screens continue to develop towards high screen-to-body ratio and high resolution. The narrow border design of the display screen has become a trend. For this, the industry generally adopts pad bending (pad bending) technology to achieve narrow borders. design. [0003] like figure 1 Shown is a display screen in the prior art, including a display panel 1 and a flexible substrate 2, the flexible substrate 100 is provided with a plurality of metal lines (metal lines) 4 for electrically connecting the display panel 1 and the printed circuit PCB (Printed Circuit Board, PCB) board 5, since there is a certain degree of bending at the bending portion 22 of the flexible substrate 2, and since the surface of the bending portion 22 in the prior art is a flat structure, it should be located at its When...
