Abstract

The invention discloses a display panel and a display device. The display panel is provided with a display area and a non-display area surrounding the display area, the display panel further comprisesa fan-out area and a driving chip, a datum line is preset below the driving chip, the datum line is parallel to one side edge, connected with the fan-out area, of the display area, and the side, awayfrom the fan-out area, of the non-display area is further provided with flat cable areas which are distributed on the two sides of the driving chip. The display panel further comprises a plurality ofbonding pads and wires. The bonding pads are distributed in the flat cable area and located on the two sides of the driving chip, each bonding pad is connected to the driving chip through a wire, andon each side of the driving chip, the heights of the bonding pads on the datum line are gradually increased in the direction from the position close to the driving chip to the position away from thedriving chip.

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] With the technical development of full-screen displays, the screen-to-body ratio of the current display screen is continuously increasing, and the lower border of the display screen is also getting smaller and smaller. [0003] Such as figure 1 As shown, the existing display panel 100 includes a display area 101 and a non-display area 102 surrounding the display area 101. In the non-display area 102, a fan-out area 1021, a driver chip 1022, and a wiring area 1023 (Flexible Printed Circuit Board, FPC ). [0004] The wiring area 1023 is distributed on both sides of the driving chip 1022 , and the wiring area 1023 includes a pad 10231 and a first wiring 10232 . The central connection lines of the plurality of pads 1023 are on the same horizontal line, and the first wiring 10232 is used to connect the p...
