Abstract

The present application relates to the technical field of liquid crystal display, and in particular, to a backlight assembly, a liquid crystal display device, and an electronic device. The backlight assembly includes a light guide plate and a backlight light source, the light guide plate includes a light guide plate body and a plurality of wedge-shaped structures, the light guide plate body includes a first surface and a second surface, and the plurality of wedge-shaped structures are arranged at intervals on one end of the first surface close to the second surface; The backlight light source is arranged adjacent to the second surface of the light guide plate body, and each backlight light source is arranged between two adjacent wedge-shaped structures, so that part of the light emitted by the backlight light source is reflected by the wedge-shaped structure and enters the light guide plate body. Part of the light is reflected in the main body of the light guide plate, and the incident angle of the reflected light of the part of the light on the first surface is greater than or equal to the critical angle of total reflection of the light entering the air from the main body of the light guide plate, thereby improving the brightness of the light guide plate. The liquid crystal display device includes a backlight assembly. The electronic equipment includes a liquid crystal display device. In the above manner, the brightness uniformity of the light guide plate is improved.

Description

technical field [0001] The present application relates to the technical field of liquid crystal display, and in particular, to a backlight assembly, a liquid crystal display device, and an electronic device. Background technique [0002] As electronic products such as mobile phones and tablets occupy an increasing proportion of people's life and work time, users have higher and higher requirements for electronic devices. Taking the brightness of the mobile phone screen as an example, in the prior art, in order to improve the brightness of the liquid crystal display device without increasing the cost and power consumption, the fixing glue in front of the backlight light source is usually designed with an opening to improve the brightness of the mobile phone screen. . However, the current technical solution has the problem of poor brightness uniformity of the liquid crystal display device. SUMMARY OF THE INVENTION [0003] The present application provides a backlight assem...
