Embodiment Construction

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0024] Such as figure 2 As shown, the present invention provides a backlight. The backlight includes a light guide plate 100 and a light source module disposed on the light incident side of the light guide plate 100. The light source module includes:

[0025] A point light source 101, the light-emitting surface of the point light source 101 is disposed away from the light guide plate 100; and,

[0026] A dimming component 102, the light-emitting surface of the point light source 101 is set facing the dimming component 102, and the dimming component 102 can reflect the light emitted by the point light source 101, and make the reflected light converge incident on the light-incident side of the light guide plate 100 ...

Abstract

The invention provides a backlight source and a display device. The backlight source comprises a light guide plate and a light source module, wherein the light source module is arranged at the light incident side of the light guide plate and comprises a point light source and a dimming assembly, a light emitting surface of the point light source is arranged in a direction of backing to the light guide plate, the light emitting surface of the point light source is arranged in a direction of facing the dimming assembly, and in addition, the dimming assembly can reflect light rays emitted by the point light source, so that the reflected light rays can be emitted into the light incident side of the light guide plate after being gathered. In the backlight source provided by the invention, the light emitted out by the point light source can be transmitted to the light incident side of the light guide plate after being reflected and gathered through the surface of a reflecting layer, and the change of the incident angle of the light rays is realized, so the problem of light leakage of the display device caused by the light emitting angle problem of the light source module can be solved, and the light efficiency of products is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight source and a display device. Background technique [0002] Due to the advantages of low operating voltage, low power consumption, flexible display methods, and low radiation, Liquid Crystal Displays (LCDs) are widely used in various fields, such as computers, mobile phones, televisions, and measurement displays. The LCD includes a liquid crystal display panel, and the liquid crystal display panel includes a thin film transistor substrate, a color filter, and a layer of liquid crystal molecules interposed between the two substrates. In addition, the LCD also includes a backlight source for providing a light source for the liquid crystal display panel so that the LCD can display images. [0003] Such as figure 1 Shown is a schematic structural diagram of a traditional backlight source. Traditional backlight usually includes back cover (Back Cover), frame (Bezel), se...
