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 comprises a display panel and a flexible substrate, the display panel comprises a plurality of adjacently-arranged gaskets, the flexible substrate comprises a display part and a bending part, a plurality of protrusions are arranged on the first surface of the bent part, at least one metal wire is arranged on the surface of each protrusion, and each metal wire is electrically connected with the corresponding gasket. On one hand, when the bending part is bent, the metal wire is attached to the surfaces of the protrusions to form a three-dimensional structure, so that the bending angle of the metal wire is changed, the tensile stress borne by the metal wire is reduced, and the stability of connection between thedisplay panel and a PCB is guaranteed; and on the other hand, the length of the metal wire can be increased, so that when the metal wire is bent, the increased length can effectively compensate for the increased length required by stretching of the metal wire.

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] Such as 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 W...
