Abstract

The invention discloses a display module, an application method thereof and a display device. The display module comprises a first display area, a second display area, a display panel and a backlightmodule, wherein the backlight module comprises a first through hole and a first supporting part at least partially located in the first through hole. The display module also comprises a photosensitiveelement which comprises a driving mechanism; a light supplementing module which comprises a light supplementing source and a flexible circuit board; and a connecting part which is connected with thephotosensitive element and the light supplementing module. The first display area comprises a display stage and a photosensitive stage, in the display stage, orthographic projections of the light supplementing module and the photosensitive element on the display panel are at least partially overlapped, and at the moment, light emitted by the light supplementing source supplements light to the first display area, so that the first display area can realize a display function, and the design of a full screen is realized; in the light sensing stage, the orthographic projections of the light supplementing module and the light sensing element on the display panel are not overlapped, so that the light supplementing module does not influence the light sensing performance of the light sensing element, and the light sensing performance of the light sensing element is improved.

Description

technical field

[0001] The present invention relates to the field of display technology, and more specifically, to a display module, an application method thereof, and a display device. Background technique

[0002] In order to meet users' demands for a high screen-to-body ratio, display panels with narrow bezels or even bezel-less have become a development trend of display devices. However, in order to meet functions such as taking pictures, some functional devices, such as cameras and light sensors, are required in the display device. In order to realize the requirement of a full screen, photosensitive devices need to be integrated under the display panel.

[0003] In the current related technologies, common designs include water drop screens, notch screens, lifting cameras, side-sliding cameras, and full screens with sliding covers. However, the design of the water drop screen and notch screen requires digging a hole in the display panel for the placement of the camera....
