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 ...

Abstract
Provided are a light emitting module and a display apparatus. The light emitting module includes: a light emitting unit and a light guide plate; the light guide plate includes a first plate surface and a second plate surface opposite to each other, and a plurality of side surfaces; the light emitting unit is configured to emit light to the light guide plate from the target side surface; the first plate surface includes a plurality of target convex ridges disposed in sequence along a direction away from the light emitting unit; each target convex ridge is configured to totally reflect light emitted from the target side surface into the light guide plate to the second plate surface, angles between the target ridge surfaces of the plurality of target convex ridges and a thickness direction of the light guide plate tends to decrease.
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...
