Embodiment Construction
[0041] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0042] With the increasing application of display devices, in order to reduce the risk of leakage of user information, anti-peep display technology is proposed, that is, the technology of reducing the viewing angle of the display device. Generally, an anti-peeping film is used to absorb part of the light emitted by the display device so as to reduce the viewing angle of the display device, but this will result in lower luminance of the display device. The light-emitting module provided by the embodiment of the present invention can directly emit relatively restrained light, and the light-emitting module can be used as a backlight module in a display device, so that the display device where the light-emitting module is located can ...

The invention discloses a light-emitting module and a display device, and belongs to the technical field of display. The light-emitting module comprises a light-emitting unit and a light guide plate;the light guide plate comprises a first bottom surface and a second bottom surface which are opposite to each other, and a plurality of side surfaces which are connected with the first bottom surfaceand the second bottom surface; the light-emitting unit is arranged close to a target side surface in the side surfaces, and is used for emitting light from the target side surface to the light guide plate; a plurality of target convex edges sequentially arranged in a direction away from the light-emitting unit are arranged on the first bottom surface, and the length direction of each target convexedge is parallel to the target side surface; the light emitted into the light guide plate by the light-emitting unit includes light which can be totally reflected to the second bottom surface on thepreset surface, far away from the light-emitting unit, of each target convex edge; and in the direction away from the light-emitting unit, the included angles between the preset surfaces of the targetconvex edges and the thickness direction of the light guide plate are reduced. The light-emitting module solves the problem that the anti-peeping display device is poor in display effect. The light-emitting module is used for displaying images.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a light emitting module and a display device. Background technique [0002] With the development of display technology, display devices such as mobile phones and computers are more and more widely used, and the current display devices all have relatively large viewing angles. When the user uses the display device, the information displayed on the display device is visible to many people, so that the risk of leakage of user information is relatively high. [0003] In the related art, the risk of leakage of user information is reduced by reducing the viewing angle of the display device. For example, a layer of anti-peeping film can be provided in the display device to absorb part of the light emitted by the light emitting module of the display device, thereby reducing the viewing angle of the display device. [0004] However, the light emitted by the light-emitting mod...
