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

Abstract

The invention provides a display panel and a display device to reduce the step width of the display panel. The display panel comprises a display area, a non-display area which comprises an integratedcircuit binding area and a fan-out area, signal lines which comprise first and second signal lines in the display area, and fan-out traces which comprise a first fan-out trace and a second fan-out trace. The first fan-out trace and the second fan-out trace are both located in the fan-out area. The first fan-out trace is electrically connected with the first signal line. The second fan-out trace iselectrically connected with the second signal line. The first fan-out trace is electrically connected with a first terminal of an integrated circuit binding area through a first side. The second fan-out trace is electrically connected with a second terminal of the integrated circuit binding area through a second side. The first side and the second side are two different sides in the integrated circuit binding area.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] When making a liquid crystal display (Liquid Crystal Display, LCD), it is usually packaged by Chip On Glass (COG) technology, and the displays packaged by the COG technology are collectively referred to as COG products. [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 ...
