Embodiment 1

[0035] In this embodiment, a display panel is provided, which is used to improve the problem that the existing output leads are routed in the frame area of ​​the display panel and the display panel cannot realize a frameless design, figure 2 It is a schematic diagram of the structure of the display panel in this solution. The left part of the figure is a top view of the display panel, and the right part is a schematic cross-sectional structure diagram obtained by cutting along the dotted line in the display panel corresponding to the left figure. The display panel includes: a substrate 221, a display layer 222 located on the substrate 221; the display panel defines a display area N corresponding to the display layer 222 and a non-display area M including at least a bonding area; For at least one edge area of ​​the display area N connected with the output lead S2: the output lead S2 is arranged between the substrate 221 and the display layer 222, and the output lead S2 is on th...

Embodiment 2

[0043] Based on the display panel structure of the above-mentioned embodiment, the embodiment of the present invention also provides a better display panel, which is used to improve the problem that the existing output leads are laid in the frame area of ​​the display panel, which restricts the display panel from being unable to achieve a frameless design. FIG. 3 is a schematic diagram of the structure of the display panel of this solution.

[0044] In the display panel structure of this embodiment, in the wiring area of ​​the output lead S2 other than the connection point between the output lead S2 and the display layer 323, a first insulating layer is arranged between the output lead S2 and the display layer. 322.

[0045] The material of the insulating layer can be polymer insulating material such as polyethylene, or rubber or organic glue. In the actual production process, affected by the production process, the insulating layer can be made of an inorganic material with s...

Embodiment 3

[0066] In this embodiment, a display device is provided, which is used to solve the problem in the prior art that a display panel needs to be provided with a frame due to the routing of output leads through a frame position, and the device includes any display panel in the above embodiments.

[0067] Based on the display panel structures of the above embodiments, the display device provided by this embodiment can realize a frameless structure on at least one edge connected with output leads. Taking a rectangular display device as an example, this solution can optimally realize a three-sided borderless structure, thereby increasing the screen-to-body ratio of the display device and improving visual experience. In addition, in addition to the display panel, the device may also include a polarizer, a filter, a protective film, etc., to improve the overall display performance of the display device or prolong the service life of the device.

Abstract

The invention relates to the technical field of display, and particularly relates to a display panel and a display device for improving a problem that the existing output leads are arranged in a framearea of the display panel and restricts the display panel from realizing the frameless design. The display panel comprises a substrate and a display layer on the substrate. The display panel definesa display area corresponding to the display layer and a non-display area which at least contains a binding area; in allusion to at least one edge area connected with an output lead in the display area, the output lead is arranged between the substrate and the display layer, and the orthographic projection of the output lead on the substrate is covered by the orthographic projection of the displaylayer on the substrate; and the output lead is mutually insulated from the display layer in an output lead wiring area except for the junction of the output lead and the display layer. There is no need to set a frame at the edge connected with the output lead of the display layer, and the output lead does not restrict the frameless design, thereby realizing the structure of a frameless display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] A display panel is a device that can output images and is widely used in electronic devices, such as mobile phones, tablet computers, TVs, smart watches, etc. As an output device, the display panel can timely feed back the processed result to the user in the form of an image according to the user's instruction, so as to better realize human-computer interaction. [0003] Existing display panel structures such as figure 1 As shown, the display panel can be divided into a display area N corresponding to where the display layer is located, and a non-display area M corresponding to where the data lines and chips are located. According to different functions, the data line can be divided into input lead a and output lead b. The non-display area M often includes a bonding area 121 and a routing area 122. Th...
