Abstract

The invention discloses a backlight module and electronic equipment, and belongs to the technical field of electronic equipment. The backlight module comprises an installation frame, a light source, a light guide assembly and a light scattering assembly, the installation frame is provided with an installation groove, the installation groove is located in the light emitting side of the backlight module, the light source is installed in the installation groove, the light guide assembly is at least partially located in the installation groove, and the light guide assembly is used for guiding light emitted by the light source to the light scattering assembly; wherein the light scattering assembly is used for scattering light rays emitted by the light source to a backlight display area. The backlight module has the advantages that the width of the shading black edge of the backlight module is smaller, and the screen-to-body ratio of the display screen is high.

Description

technical field [0001] The application belongs to the technical field of electronic equipment, and in particular relates to a backlight module and electronic equipment. Background technique [0002] With the rapid development of the electronic equipment industry, consumers have higher and higher requirements for the screen ratio of the display screen. Taking mobile phones as an example, the display screens of some mobile phones are liquid crystal displays (Liquid Crystal Display, LCD), and the traditional LCD screens are under great pressure. [0003] In the advanced technology, LCD screens have also introduced various solutions to increase the screen-to-body ratio, such as Chip On Flex (or, Chip On Film, commonly referred to as COF) structure, narrow borders, etc. [0004] However, an important bottleneck in improving the screen-to-body ratio of LCD screens is that the width of the black border in the light-mixing area on the light incident side of the backlight is relativ...
