Display panel, manufacturing method thereof, display screen and display device

Abstract

The invention discloses a display panel, a manufacturing method thereof, a display screen and a display device. The display panel includes a substrate, a plurality of first electrode signal lines formed on the substrate, and a plurality of isolation columns which are located on one side, which is away from the substrate, of the first electrode signal lines. The display panel includes a plurality of pixel regions and a plurality of blocking regions. Isolation columns are arranged in the pixel regions. A plurality of pixel openings are arranged in the isolation columns. A first electrode and a light-emitting functional layer which is located on one side, which is away from the substrate, of the first electrode are arranged in each pixel opening. Each first electrode is electrically connectedwith the corresponding first electrode signal line. Each blocking region is used to block a second electrode between two adjacent pixel regions. According to the technical scheme of the invention, while the second electrode between adjacent pixel regions is blocked to realize full-screen display, the thickness of the display panel is greatly reduced; and the production efficiency of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a manufacturing method thereof, a display screen, and a display device. Background technique [0002] With the rapid development of electronic devices, users have higher and higher requirements for screen-to-body ratio, so that the full-screen display of electronic devices has attracted more and more attention from the industry. [0003] Traditional electronic devices such as mobile phones, tablet computers, etc., need to integrate such as front camera, earpiece, and infrared sensing components, so it is possible to set the camera, earpiece, and infrared sensing elements in the slotted area by slotting (Notch) on the display screen. Components, etc., but the slotted area is not used to display the picture, such as the notch screen in the prior art, or the method of opening holes on the screen. For electronic equipment that realizes the...

Problems solved by technology

However, these electronic devices are not truly full-screen, and cannot be displayed in all areas of the entire screen. For example, images cannot be displayed in the camera area.
