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]As used in the specification and claims, certain terms are used to refer to particular components. It should be understood by those skilled in the art that hardware manufacturers may refer to the same component by different nouns. The description and claims do not use the difference in name as a way to distinguish components, but use the difference in function of the components as a criterion for distinguishing. As mentioned in the entire specification and claims, "comprising" is an open-ended 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. Furthermore, the term "coupled" herein includes any direct and indirect means of electrical coupling. Therefore, if a first device is described as being coupled to a second device, it means that the first device can be dire...

Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. The display panel comprises a first substrate which comprises a display region and a non-display region surrounding the display region; an electric connection part which is disposed on the first substrate, is located in the non-display region, and comprises a first conductive gasket group and second conductive gasket groups located at two sides of the first conductive gasket group. The first conductive gasket group comprises a plurality of first conductive gaskets, and each second conductive gasket group comprises a plurality of second conductive gaskets, wherein the length of each second conductive gasket is less than the length of each first conductive gasket. The area of the orthographic projection of the second conductive gaskets on a plane where the first substrate is located is equal to the area of the orthographic projection of the first conductive gaskets on the plane where the first substrate is located. Therefore, the reduction of the frame width of the display panel and the frame width of the display device is facilitated, thereby achieving the narrow frame design of the display device, improving the screen-to-body ratio, and achieving the uniformity of the binding effects of the first and second conductive gaskets and the uniformity of the conductive effects of the first and second conductive gaskets.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] As the panel display becomes more and more widely used, the widescreen technology has become an important technical item, and at the same time, the technology of the narrow lower frame of the display panel is also becoming more and more important. Advanced electronic products, especially hand-held electronic products, tend to be smaller and smaller. COF (chip on flexible, flexible chip) technology is an important technology for realizing small size 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, thereby realizing the miniaturization of the entire display device. [0003] In order to bind the flexible circuit board to the display panel, it is usually necessa...
