Embodiment Construction

[0046] 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.

[0047] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that different hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specif...

Abstract

The invention provides a backlight module and an electronic device. The backlight module comprises: a substrate, a plurality of light sources and a plurality of light blocking structures. The plurality of light sources are arranged on one side of the substrate, the light blocking structure is arranged between at least two of the light sources, and a light emitting material layer is arranged on oneside of the light blocking structure away from the substrate. Therefore, in the scheme, by setting the light blocking structures among the plurality of light sources, the light of the light sources is blocked by the light blocking structures, thereby reducing the overlapping of the light between the adjacent light sources and avoiding the halo phenomenon from the root source. Moreover, in the backlight module provided by the invention, the light emitting material layer is arranged on one side of the light blocking structure away from the substrate, and the light emitting material layer can passively emit light when the light sources emit light, thereby reducing the occurrence possibility of a grid pattern phenomenon in a corresponding area of the light blocking structure in a light emitting process of the backlight module, and further improving the display effect of a display device.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, and more specifically, relates to a backlight module and electronic equipment. Background technique [0002] With the continuous development of liquid crystal display technology, liquid crystal display modules have been widely used in electronic devices such as mobile phones and tablet computers. However, since the liquid crystal display panel in the liquid crystal display device does not have the function of emitting light, it is necessary to install a backlight module under the liquid crystal display panel to provide the required light source to achieve the display effect. [0003] Usually, the luminous effect of the backlight module will directly affect the visual effect of the liquid crystal display module. The backlight module is mainly composed of a light source, a light guide plate, an optical film, etc., and can be divided into side-type and direct-type according to the pos...
