Embodiment Construction
[0024] The present invention will be described in detail below in conjunction with the drawings and embodiments.
[0025] See figure 1 , figure 1 It is a schematic diagram of the structure of the display panel of the present invention. In this embodiment, the display panel 1 includes a display area 11 and a bonding area 12.
[0026] There are multiple signal lines 111 a, 111 b, and 111 c on the display area 11, and pads 121 are provided on the bonding area 12.
[0027] The fan-out line structure 13 includes a plurality of fan-out lines 131a, 131b, and 131c arranged between the display area 11 and the bonding area 12. The first ends of the fan-out lines 131a, 131b, and 131c are connected to the pad 121, and the fan-out lines 131a, 131b, The second end of the 131c is connected to the signal lines 111a, 111b, and 111c (for example, the signal line is a scan signal line or a data signal line on the display panel 1). The shape of the fan-out lines 131a, 131b, and 131c can be a straight ...

The invention discloses a fan-out line structure of a display panel. The display panel comprises a display area and a joint area. The display area is provided with multiple signal lines. The joint area is provided with a bonding pad. The fan-out line structure comprises multiple fan-out lines which are arranged between the display area and the joint area. The fan-out lines are of a double-layer wire structure which comprises a first conducting layer and a second conducting layer. At least a part of the projection of the first conducting layer and a part of the projection of the second conducting layer in a plane where the display panel is located are staggered, wherein the first conducting layer and the second conducting layer are arranged in middle sections of the fan-out lines. The fan-out line structure of the display panel can lower the static risk between the two conducting layers in the fan-out lines, thereby being capable of improving product yield and reducing cost.
Description
Technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and its fan-out line structure. Background technique [0002] With the development of the information society, people's demand for display devices has increased, which has also promoted the rapid development of the LCD panel industry. Reducing costs, improving product yield and improving product quality have become the focus of the LCD panel industry. [0003] The liquid crystal display panel includes a display area and a bonding area. There are multiple signal lines on the display area and pads are arranged on the bonding area. A fan-out line is arranged between the display area and the bonding area, the fan-out line is connected between the pad and the signal line, and the fan-out line has two types of single-layer and double-layer wire structures. The double-layer wire structure of the prior art includes two conductive layers and the two conductive layers ar...
