Problems solved by technology

Placing the camera with an opening in the display area of ​​the display can maximize the screen-to-body ratio, but the hole-digging technology requires very strict glass cutting accuracy and process capabilities, so this method faces problems such as low production capacity, low yield, and high cost.
Another solution is to keep the glass substrate and the film layers (such as gate insulating layer and interlayer insulating layer) that are produced synchronously corresponding to the display area, thus reducing the light transmittance of the display panel in the module setting area

Abstract

The present invention provides a display panel, a display device, and a display panel manufacturing method. The display panel includes a display area and a non-display area; the display area surroundsthe non-display area; the non-display area includes a module setting area; the light transmittance of the display panel in the module setting area is greater than a preset value; the display panel includes an array substrate; the array substrate includes: a first substrate; a buffer layer located at one side of the first substrate; a plurality of thin film transistors located on a side of the buffer layer away from the first substrate; a film layer where the plurality of thin film transistors are located only exists in a region of the non-display area except the module setting area and the display area; and the buffer layer is present in the display area and the non-display area, and covers the module setting area. The invention aims to improve the light transmittance of the display panelin the module setting area, reduce the process and improve the production efficiency.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a method for manufacturing the display panel. Background technique [0002] With the continuous development of display technology, display screens such as "borderless" and "full screen" have become research hotspots in the display field. A larger screen-to-body ratio brings users a better visual experience and can display more information. Therefore, pursuing a larger screen-to-body ratio has become the mainstream development trend of display products. [0003] In the existing technology, in order to pursue a high screen-to-body ratio, the display products continue to compress the frame, and at the same time design a special-shaped screen. The full screen with a hole structure will become the latest design trend. The hole position can be used to place devices such as cameras and earpieces. Placing the camera with an opening in the d...
