Example Embodiment

[0023] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0024] like figure 1 As shown, it is a structural principle diagram of a wiring board according to an embodiment of the present invention. The wiring board 100 of the present invention is used to connect the driver chip 200 and the display panel 300, and the driver chip 200 and the display panel 300 are arranged in pairs. There are signal output interfaces and signal input interfaces. The wiring board 100 includes fan-out lines for connecting the paired signal output interfaces and signal input interfaces. The fan-out lines realize the signal connection between the driver chip and the display panel.

[0025] like figure 2 As shown, it is a structural schematic diagram of an existing wiring board. The existing wiring board 100 forms a plurality of fan-o...

Abstract

The invention belongs to the field of display and discloses a wiring board, a flexible display screen and a display device, wherein the wiring board is connected with a drive chip and a display panel. The drive chip and the display panel are provided with signal output interfaces and signal input interfaces in pairs. The wiring board comprises fan-out lines which are used for being connected with the signal output interfaces and the signal input interfaces which are arranged in pairs. The wiring board comprises a substrate. Multiple first connecting lines with the first resistivity are arranged on the first surface of the substrate. Multiple second connecting lines with the second resistivity are arranged on the second surface, opposite to the first surface, of the substrate. At least a part of the fan-out lines are formed by connecting the first connecting lines and the second connecting lines. According to the wiring board, due to the facts that at least a part of the fan-out lines are formed by connecting the first connecting lines and the second connecting lines and the first connecting lines and the second connecting lines are located on the different surfaces of the substrate and are different in resistivity, and then the resistance of the fan-out lines can be controlled.

Description

technical field [0001] The invention relates to the display field, in particular to a wiring board for connecting a driving chip and a display panel, a flexible display screen and a display device. Background technique [0002] The display panel of the display device is driven by a driver chip, and the driver chip is connected to the display panel through a plurality of fan-out lines. With the development of electronic technology, in order to save space, the size of the driver chip is getting smaller and smaller. The display panel needs to be designed according to the needs of customers. Generally, the size of the display panel is larger than that of the driver chip. [0003] As the size of the display device increases, the distance between the fan-out line and the panel is different. Since the length of each fan-out line is different, the resistance of the fan-out line is different, and the delay of the propagation signal when passing through the fan-out line appears. , t...
