Backlight source and electronic device

Abstract

The invention discloses a backlight source comprising a light-emitting body (140), a supporting frame (110) and an optical assembly (120). The light-emitting body (140) is arranged at one side of theoptical assembly (120). The optical assembly (120) consists of a light guide plate (121), a diffusion sheet (122) and a brightness enhancement film which are sequentially stacked in the supporting frame (110). The light-emitting body (140) is arrange at the side surface of the light guide plate (121); an avoidance hole (A) is formed in the optical assembly (120) in the thickness direction in a communication manner; and a shooting hole (B) is defined in the part, in the avoidance hole (A), of the supporting frame (110). The light guide plate (121) includes surface for forming the hole wall of the avoidance hole (A); an area, away from the light-emitting body (140), of the surface is a diffuse reflection area; or a light absorption layer (150) is attached to the area, away from the light-emitting body (140), of the surface. Therefore, a problem that light leakage exists in a backlight source hole of the existing electronic device can be solved. In addition, the invention discloses an electronic device.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a backlight source and electronic equipment. Background technique [0002] With the improvement of user needs, the performance of electronic equipment is becoming more and more optimized. At present, electronic devices are developing towards a larger and larger screen-to-body ratio. How to increase the screen-to-body ratio of electronic devices is the current focus of research and development by electronic device manufacturers. [0003] However, the front camera of the electronic device is usually arranged on one side of the display screen, which will occupy a larger board space of the electronic device, and ultimately affect the screen ratio of the electronic device. Based on this, the hole-digging screen has become an effective solution commonly used in current electronic equipment. Under the premise of not affecting the normal shooting of the camera set under...

AI Technical Summary

Problems solved by technology

The light projected by the illuminant will be transmitted along the light guide plate of the backlight and reflected at the edge of the light guide plate used to form the opening. Since the edge of the light guide plate forming the opening is relatively small from the display area of ​​the liquid crystal display, therefore More reflected light can be seen in the display area, resulting in visual light leakage in the display area, which will eventually affect the display performance of electronic devices
