Display device and screen light supplementing method thereof

Abstract

The present invention discloses a display device and a screen light supplementing method thereof, which comprises a first display panel and a second display panel arranged opposite to each other. Thefirst display panel includes an imaging element, a first display module, a first light guide plate on one side of the first display module away from the second display panel and a first light source on a light incident side of the first light guide plate. The light source is turned on during screen light supplementing. The second display panel can achieve a screen-to-body ratio close to 100% without the imaging element. The imaging element of the first display panel can be used for shooting in a front imaging mode and a rear imaging mode. The first display panel is provided with the first light source and the first light guide plate on a light emission side of the display module; the first light source is turned on when the screen light need be supplemented; the emitted light of the firstlight source is transmitted through the first light guide plate and is emitted directly to the outside of the first display panel; the supplementary light is prevented from passing through the film layer of the display module to reduce the brightness, thereby the screen supplementary light with high brightness and high uniformity is provided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a method for supplementing light on a screen thereof. Background technique [0002] Full screen is a relatively broad definition of the mobile phone industry for ultra-high screen-to-body ratio mobile phone design. Literally, it means that the front of the display screen is all screens, the occupied size of the frame is compressed, and the screen ratio is close to 100%. However, the current display devices such as mobile terminals need to install components such as cameras and fill lights at the frame position, which cannot realize a true full screen. [0003] In order to reduce the screen space occupied by the camera element as much as possible, the current solution uses a special-shaped screen, digs a hole in the screen to set the camera, or sets the camera below the screen, so that the screen needs to be used for supplementary light when shooting.

Problems solved by technology

However, at the present stage, the screen fill light is supplemented by the inherent light source such as the backlight of the display device. The light source needs to go out through the multi-layer film of the display device, and the emitted light intensity is not high, so the fill light effect needs to be improved.
