Electronic device and display control method

Abstract

The invention provides an electronic device which comprises a liquid crystal display layer, a backlight module and a camera. The liquid crystal display layer comprises a display area, a light supplement area and a first through hole, and the light supplement area is located around the first through hole. The backlight module is provided with a second through hole corresponding to the first throughhole. The camera is arranged in a space formed by the first through hole and the second through hole. No filter layer is arranged or the pixel area is increased in the light supplement area to improve the light transmittance of the light supplement area of the liquid crystal display layer. A light guide plate is provided with scattering particles and microstructures corresponding to the light supplement area to improve the light output efficiency of the light supplement area. The luminous intensity of a direct-down backlight source corresponding to a light source of the light supplement areais larger than that of a light source of the display area to improve the light output intensity of the light supplement area. Thus, the electronic device overcomes the defect that bright and dark bands appear around an original through hole, and original modules of the light supplement area of the electronic device are designed to realize the double functions of photographic light supplement and illumination.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to an electronic equipment and a display control method. Background technique [0002] In order to realize the Selfie function, there is always a front camera on the screen. In order to maximize the screen area, the front camera is integrated into the display area of ​​the screen, which requires the display to have a perforated design. In the current side-type backlight module, the light distribution near the perforation is uneven. For example, when using a side-type light source, there will be a bright band around the semicircle on the side of the perforation close to the side-type light source, while the perforation is far away from the edge of the side-type light source. There will be dark bands around the semicircle on the other side, so the border of the perforated design will easily produce bright and dark bands, resulting in uneven brightness around th...

Problems solved by technology

In the current side-type backlight module, the light distribution near the perforation is uneven. For example, when using a side-type light source, there will be a bright band around the semicircle on the side of the perforation close to the side-type light source, while the perforation is far away from the edge of the side-type light source. There will be a dark band around the semicircle on the other side, so the border of the perforated design is prone to produce bright and dark bands, resulting in uneven brightness around the camera in the screen

When the camera shoots images in a dark environment, it will be too dark to lose details or be distorted, and it needs to be supplemented with light. In the existing technology, the front camera embedded in the screen does not use the supplementary light mechanism due to design limitations.
