Problems solved by technology

In the electrical connection part of the display panel, there is still room for compression of the signal traces connected to the conductive pads located in the middle area, but the signal traces connected to the conductive pads located on the left and right sides cannot be further compressed.
Due to the lack of space for the signal traces connected to the conductive pads on the left and right sides, the frame of the display device cannot be further compressed, so it is difficult to achieve a narrow frame design

Embodiment Construction

[0044]Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electr...

Abstract

The present application discloses a display panel and a display device, which relate to the field of display technology. The display panel includes: a first substrate including a display area and a non-display area surrounding the display area; The part is located in the non-display area, and the electrical connection part includes a first group of conductive pads and a second group of conductive pads located on both sides of the first group of conductive pads; the first group of conductive pads includes a plurality of first conductive pads, and the second group of conductive pads The second conductive pad group includes a plurality of second conductive pads, the length of each second conductive pad is smaller than the length of the first conductive pad, and the area of ​​the orthographic projection of the second conductive pad on the plane where the first substrate is located is equal to the first conductive pad. The area of ​​the orthographic projection of a conductive pad on the plane where the first substrate is located. In this way, it is beneficial to reduce the frame width of the display panel and the display device, realize the narrow frame design of the display device, increase the screen ratio, and also help to realize the uniformity of the binding effect of the first conductive pad and the second conductive pad and the conductive uniformity of effect.

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] As panel displays are more and more widely used, widescreen technology has become an important technical item. At the same time, the technology of narrow lower borders of display panels is also becoming more and more important. Advanced electronic products, especially portable electronic products, tend to be smaller in size. COF (chip on flexible, flexible chip) technology is an important technology to realize the miniaturization of electronic products. The so-called COF technology refers to designing the driver chip IC in a flexible material, and then folding the flexible material to the back of the display panel, so as to realize the miniaturization of the entire display device. [0003] In order to bind the flexible circuit board to the display panel, it is usually necessary to design an electric...
