Definitions
- the existing driving chip and the display panel are not matched in size, and the present disclosure provides a wiring for connecting the driving chip and the display panel. Board, flexible display and display device.
- the fan-out line forms a predetermined angle between the connecting lines of at least a portion of the adjacent segments.
- the predetermined angle is 30-150 degrees.
- the first connecting line and the second connecting line in the fan-out line are connected through a via hole.
- the first connecting line is formed of a material having a first resistivity
- the second connecting line is formed using a material having a second resistivity different from the first resistivity
- FIG. 1 is a structural relationship diagram of a driving chip, a wiring board, and a panel according to an embodiment of the present disclosure
- FIG. 6 is a schematic diagram of a fan-out line distribution according to an embodiment of the present disclosure.
- the wiring board 100 of the present disclosure is used to connect the driving chip 200 and the display panel 300, and the driving chip 200 and the display panel 300 are provided with a signal output interface and a signal input interface in pairs.
- the wiring board 100 includes a fan-out line for connecting a signal output interface and a signal input interface which are disposed in pairs, and the fan-out line realizes a signal connection between the driving chip and the display panel.
- the first connection line 1011 and the second connection line 1012 may be formed of a metal material such as copper or iron.
- the substrate can be formed from a variety of suitable materials. For example, when applied to a flexible display, the substrate may be formed using a flexible material such as resin or plastic.
- the plurality of first connecting lines or the second connecting lines may be formed by forming a conductive thin film layer on the surface of the substrate and then etching the conductive thin film layer.
- the area of the display panel 300 is much larger than the area of the driving chip 200. This At the time, the length of the fan-out line 101 connecting the driving chip 200 and the display panel 300 is different. If each fan-out line 101 is formed of a material having the same resistivity, the signal transmission time on the fan-out line 101 is positively correlated with the length of the fan-out line 101. At this time, when driving each gate line, there is a delay, which affects the uniformity of the screen. To this end, at least a portion of the fan-out line 101 of the present embodiment is formed by a first connection line 1011 and a second connection line 1012 having different resistivities on different surfaces of the substrate.
- FIG. 4-5 a schematic structural view of a fan-out line according to an embodiment of the present disclosure is shown.
- the fan-out line shown in FIG. 4 has a bent shape, and adjacent two connecting lines have a predetermined angle.
- the predetermined angle is 30-150 degrees.
- the wiring board can be applied to the flexible display screen.
- the pressure generated on the fan-out line is at an angle with the extending direction of each segment on the fan-out line, thereby reducing the direct application to each segment of the connecting line.
- the force is such that the damage to each segment of the wire is reduced when bent.
