Embodiment Construction

[0028] Aiming at the problems existing in the prior art that the ESD circuit and some signal traces exceed the cutting line due to the compression of the lower frame size, and the design space of the two-dimensional code is small, the embodiment of the present invention provides a display panel and a display device .

[0029] The specific implementation manners of the display panel and the display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The size and shape of each structure in the drawings do not reflect the real scale, but are only intended to schematically illustrate the content of the present invention.

[0030] An embodiment of the present invention provides a display panel, such as Figure 2a As shown, it includes: an array substrate 1, and an opposite substrate 2 arranged opposite to the array substrate 1; wherein,

[0031] The array substrate 1 includes: a facing area tha...

Abstract

The invention discloses a display panel and a display device. The display panel comprises an array substrate and an opposite substrate arranged opposite to the array substrate. The array substrate comprises a directly facing area and an extending area, wherein the directly facing area overlaps the orthographic projection of the opposite substrate onto the array substrate, and the extending area islocated on one side of the directly facing area and extends outward relative to the opposite substrate; the extending area comprises an underlayer substrate, a ground wire, contact terminals and electrostatic protection circuits, wherein the ground wire, the contact terminals and the electrostatic protection circuits are located on the underlayer substrate; the contact terminals are connected with a shielding layer on the opposite substrate through conductive adhesive, and the contact terminals are connected with the ground wire; the electrostatic protection circuits are located on the side,close to the underlayer substrate, of the contact terminals, and at least parts of the orthographic projections of the figures of the electrostatic protection circuits and the contact terminals onto the underlayer substrate overlap. By means of the display panel, the design space of a special shape and the design space of a two-dimensional code can be increased, and the functions of the electrostatic protection circuits and the contact terminals are not influenced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the rapid development of display technology, in addition to the traditional information display and other functions of the display, the appearance requirements are also gradually increasing. For example, the current full-screen mobile phone is favored by consumers, and the border area is reduced and the special-shaped design , to achieve a larger screen-to-body ratio is the future trend of the market. [0003] In the prior art, there are some solutions for reducing the frame area, for example, bonding an integrated chip (IC) on a flexible printed circuit (FPC), that is, COF (chip on FPC) technology. COF technology can significantly reduce the size of the lower frame. In order to meet the needs of users for the appearance of the display, special-shaped designs can be made on the display screen, such as C / R...
