Display panel and display device

Abstract

The present application provides a display panel and a display device, which are used to reduce the step width of the display panel. The display panel includes: a display area; a non-display area, including an integrated circuit binding area and a fan-out area; a signal line, including a first signal line and a second signal line, and the first signal line and the second signal line are located in the display area; the fan-out routing includes a first fan-out routing and a second fan-out routing, and the first fan-out routing and the second fan-out routing are both located in the fan-out area, and the first fan-out routing and the second fan-out routing are both located in the fan-out area. A fan-out routing is electrically connected to the first signal line, and the second fan-out routing is electrically connected to the second signal line; wherein, the first fan-out routing is bound to the integrated circuit through the first side The first terminal of the fixed area is electrically connected, the second fan-out line is electrically connected to the second terminal of the integrated circuit binding area through the second side, and the first side and the second side are the integration Distinct two edges in a circuit bonding region.

Description

Technical field [0001] The present application relates to the field of display, in particular, to a display panel and a display device. Background technique [0002] When the LCD Crystal Display, LCD is produced, the Chip On Glass, COG will be encapsulated, and the display is collectively referred to as a COG product by a display of COG technology. [0003] In the existing COG product, the signal line of the display area is electrically connected to the terminal (PAD) of the fan-out trace and the integrated circuit binding area, the area between the display area and the integrated circuit binding area is called the fan-out area, fan The fan out of the outgoing zone is inverted, causing the line width of the wire between the integrated circuit binding zone and the signal line in the display area. As a result, there is a need to leave a sufficient distance between the integrated circuit binding zone to the display area so that the corresponding signal line can increase the step wid...

AI Technical Summary

Problems solved by technology

[0003] In existing COG products, the signal lines in the display area are electrically connected to the terminals (pads) of the integrated circuit binding area through fan-out routing. The area between the display area and the integrated circuit binding area is called the fan-out area. The fan-out traces in the out-of-area are distributed in an inverted trapezoidal shape, resulting in a wider line width of the traces between the integrated circuit bonding area and the signal lines in the display area

In this way, a sufficient distance needs to be left between the integrated circuit binding area and the display area so that the corresponding signal lines can be received, which will increase the step width of the display panel
