Backlight modules, liquid crystal display modules and electronic equipment

Abstract

The invention discloses a backlight module, a liquid crystal display module and electronic equipment. In the backlight module, a prism light guide structure is arranged on the periphery of the backlight area, and a fluorescent powder layer is arranged on the outer surface of the prism light guide structure. The prism light guide structure can change the propagation direction of the light emitted by the LED light-emitting element adjacent to the prism light guide structure, so as to reduce the incident angle of the exit light relative to the fluorescent film, so that the light diverging from the backlight module to the periphery can be reduced A smaller incident angle enters the fluorescent film or is vertically incident on the fluorescent film, thereby increasing the intensity of light irradiating the periphery of the fluorescent film, and stimulating the periphery of the fluorescent film to emit more white light. The prism light guide structure can avoid the gathering of peripheral blue light through the scattering effect of phosphor particles on its surface, and solve the problem of bluish backlight around the peripheral edge. The liquid crystal display module and the electronic equipment include the backlight module, which solves the problem of bluish edges around the backlight and improves image display quality.

Description

technical field [0001] The invention relates to the technical field of electronics, and more specifically, relates to a backlight module, a liquid crystal display module and electronic equipment. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with display functions are widely used in people's daily life and work, which brings great convenience to people's daily life and work. essential tool. The main component of an electronic device to realize a display function is a display panel. Currently, a display panel commonly used in electronic equipment is a liquid crystal display panel. The liquid crystal display panel includes a liquid crystal display module and a backlight module arranged opposite to each other. The backlight module itself does not emit light, and uses the backlight provided by the backlight module to display images. [0003] High-Dynamic Range (HDR) images have higher color depth, wid...
