Abstract

The invention provides a light guiding component, a backlight module, and a display device. The light guiding component comprises a first light guiding member and a plurality of second light guiding members. The first light guiding member comprises opposite first and second surfaces. The first surface is provided with a plurality of dots for light exiting. The second light guiding members respectively fixedly connected to the second surface. Each of the second light guiding members respectively comprises a light incident end surface for light entering the second light guiding member in a side-entry manner. The light guiding component can solve the problem that the backlight module of the light guide plate in the prior art cannot meet the requirements of light and thinning and the sub-areacontrol of the light source by providing the first light guiding member and the plurality of second light guiding members.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a light guide assembly, a backlight module and a display device. Background technique [0002] At present, the structure used to form a surface light source in the backlight module of a liquid crystal display includes a direct-type and a side-type. Among them, a display using a direct-type backlight module has a light source that can be controlled by region, and the light is uniform, and can be applied to a large-area display panel. However, since the light source needs enough space for light mixing, the thickness of the backlight module cannot be reduced, and it cannot meet the thinner and lighter requirements of the display. The display using the side-type backlight module has the advantage of being able to adapt to the requirements of thinning and thinning, but the disadvantage is that the light source can only be controlled in one-dimensional direction by region, and cannot ...
