Problems solved by technology

The liquid crystal display device is a light-transmitting display device. When displaying, a backlight is required to provide the brightness required for the display. For most liquid crystal display modules, the backlight is usually in a constant light mode and is uniformly controlled. During the process, there are shadows around the effective information display area, which reduces the contrast of the display device and the display effect is not good

Embodiment Construction

[0053]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 specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be direc...

Abstract

The application discloses a backlight module and a display device, which relate to the field of display technology. The backlight module includes: a substrate and a plurality of light-emitting diode elements arranged on the substrate along a first direction and a second direction; The second direction intersects; a retaining wall structure is also provided on the base plate, and the retaining wall structure includes a plurality of first retaining walls extending along the first direction and arranged along the second direction and arranged along the first direction and extending along the second direction The second retaining wall, the orthographic projection of the first retaining wall and the second retaining wall on the plane where the substrate is located is located between adjacent LED elements; the side walls of the first retaining wall and the second retaining wall are provided with reflective layers, and the second retaining wall A light guide layer is provided on the surface and at least part of the side wall of the first retaining wall and the second retaining wall away from the substrate. In this way, the light-emitting diode elements in the backlight module can be partitioned to achieve the function of light convergence, reducing the possibility of light diffusion in the effective information display area to the periphery, which is beneficial to improving the display effect of the display device.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a backlight module and a display device. Background technique [0002] With the continuous development of liquid crystal display technology, liquid crystal display modules have been widely used in liquid crystal display 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] The backlight module is located behind the liquid crystal display module and provides light source for the normal display of the liquid crystal display module. The luminous effect of the backlight module will directly affect the visual effect of the liquid crystal display module. The backlight module is mainly com...
