Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] In the existing liquid crystal display panel of HDR display mode, the direct-lit backlight module generally adopts Mini LED with excellent blue light as the light emitting element. Because the cutting precision of the fluorescent film around the periphery (surrounding edge) of the backlight module is not the same, the concentration of phosphor powder in the peripheral fluorescent film is different; The intensity is small and the excitation energy is sma...

Abstract

The invention discloses a backlight module, a liquid crystal display module and electronic equipment. In the backlight module, a prism light guiding structure is arranged at periphery of a backlight area, a fluorescent powder layer is arranged at an external surface of the prism light guiding structure, a propagation direction of light outgoing from an LED light emitting element adjacent to the prism light guiding structure can be changed through the prism light guiding structure, thus, an angle of incidence of the outgoing light relative to a fluorescent film is reduced, the light emitted towards the periphery by the backlight module irradiates on the fluorescent film with a relatively small angle of incidence or vertically irradiates on the fluorescent film, light intensity irradiating on the periphery of the fluorescent film is improved, and the periphery of the fluorescent film is motivated to emit more white light. The prism light guiding structure can avoid aggregation of periphery blue light through a scattering effect of surface fluorescent powder particles of the prism light guiding structure, and thus, a problem that surrounding edge backlight is bluish is solved. The liquid crystal display module and the electronic equipment comprise the backlight module, the problem that the surrounding edge backlight is bluish is solved, and image display quality is improved.

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...
