Problems solved by technology

[0003] In order to achieve borderless display, the traditional method requires at least two layers of lenses above the display panel, which will significantly increase the overall thickness of the display panel. The brightness of the image display is greatly reduced, and the refraction of the double lens is also likely to cause image distortion

Embodiment 1

[0030] This embodiment provides a display panel, such as figure 1 As shown, it includes a display substrate 1 and a light processing element 2 arranged on the light emitting side of the display substrate 1. The display substrate 1 includes a frame area 11 and a display area 12 surrounded by the frame area 11. The display substrate 1 is bent at least in the frame area 11, and the light processing The element 2 is at least correspondingly arranged in the frame area 11 for changing the direction of light emitted from the display substrate 1 so that the image displayed on the display area 12 can cover the frame area 11 .

[0031] In this embodiment, the display substrate 1 is curved as a whole, and the light processing element 2 corresponds to the display substrate 1 that is curved as a whole.

[0032] Among them, the display substrate 1 refers to a complete display module capable of image display, and the display substrate 1 can be any flexible and bendable image display such as ...

Embodiment 2

[0044] This embodiment provides a display panel. The difference from Embodiment 1 is that figure 2 with image 3 As shown, the frame area 11 is curved toward the direction opposite to the light output of the display substrate 1 to form an arc surface, the arc surface is convex in the light output direction of the display substrate 1, the display area 12 is flat, and the light processing element 2 is correspondingly arranged above the frame area 11. Prism group or convex lens. In this embodiment, the light processing element 2 is a prism group.

[0045] The frame area 11 is curved, so that the bordering edge 121 of the display area 12 and the frame area 11 can also form a certain curved arc surface. When displaying, the light emitted by the arc bordering edge 121 is emitted along the normal direction of the arc surface Therefore, the light emitted from the bordering edge 121 is divergent. Compared with the planar display substrate 1, the irradiation range of the light emitte...

Embodiment 3

[0056] This embodiment provides a display device, including the display panel in any one of Embodiments 1-2.

[0057] In this embodiment, there is one display panel, that is, a single-screen display device, and the single-screen display device can realize borderless display by using the display panel in any one of embodiments 1-2.

[0058] Certainly, there may be a plurality of display panels, and the plurality of display panels are spliced ​​into one, so that a super large screen display formed by splicing can be realized. Since each of the display panels adopts any one of the display panels in Embodiments 1-2, no seams will appear in the entire spliced ​​large-screen display, thereby improving the display effect of the display device.

[0059] The display device provided by the present invention may be any product or component with a display function such as a liquid crystal panel, a liquid crystal television, a monitor, an OLED panel, an OLED television, a mobile phone, and...

Abstract

The invention provides a display panel and a display device. The display panel comprises a display substrate and light processing elements which are arranged at the light exit side of the display panel; the display substrate comprises a border area and a display area encircled by the border area; the display substrate bends in at least the border area; the light processing elements are correspondingly installed in at least the border area for changing the direction of light emitted from the display substrate, so as to make the image displayed in the display area be able to cover the border area. The display panel achieves the display without borders by bending the display substrate in at least the border area, and then installing the light processing elements in at least the border area corresponding to the display substrate, thus greatly reducing the overall thickness of the 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] Today, in various small, medium and large-size display products, it has become an obvious trend to pursue fashionable appearance. All kinds of mobile phones, tablet computers and TVs will have "narrow border" or even " "Borderless" is the mainstream direction of research and development. In addition, the current demand for various super-large-screen displays is also increasing day by day, and splicing display is the main way to realize super-large-screen displays. When the display devices are spliced, the existence of the frame of each single-screen display will cause seams in the large screen after splicing, resulting in a sense of division of the overall picture, which seriously affects the overall effect of the picture. Therefore, if the display frame can be completely eliminated by technical means...
