Problems solved by technology

For a display panel using a COF packaging process, the width of its lower border is mainly limited by the vertical size of the fanout area (fanout) and the binding area, and with the increase in the pixel density of the display panel, the vertical size of the fanout area and the binding area Difficult to scale down any further, resulting in a larger size for the lower bezel of the display panel

Abstract

The embodiment of the present invention discloses a display panel and a display device. The display panel includes a display area and a non-display area surrounding the display area. The non-display area is provided with a plurality of fan-out lines and a plurality of first bonding pads. The lines are led out from the display area and electrically connected to the first bonding pads, the first bonding pads are arranged along the first direction, each first bonding pad includes a first pad part and a second pad part, and The first end of the first pad portion in each first bonding pad is in electrical contact with the first end of the second pad portion, and the second end of the second pad portion is electrically connected to the corresponding fan-out wiring. The length direction of the first pad portion intersects the length direction of the second pad portion, and the acute angle formed between the long side of the second pad portion and the connected fan-out wiring is less than 30°. The technical solution of the embodiment of the present invention further narrows the frame of the display panel while ensuring the effective bonding area of ​​the first bonding pad.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of display panels, and in particular, to a display panel and a display device. Background technique [0002] With the wide application of electronic products such as mobile phones, more and more requirements are placed on the non-display area of ​​the display panel, and narrow bezels have become the development trend of electronic products. [0003] In order to achieve a narrow frame, the current chip packaging mainly adopts a chip on film (COF, Chip On Film) and a chip on plastic (COP, Chip On Pi) packaging process. For the display panel using COF packaging process, the width of the lower border is mainly limited by the vertical size of the fanout area and the binding area. It is difficult to shrink any further, resulting in a larger size of the lower bezel of the display panel. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a display panel and a dis...
