Embodiment Construction

[0036] 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.

[0037] With the development of display technology, a lot of information of users is stored on display devices such as mobile phones and computers. important. Usually, a layer of anti-peeping film is 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. However, such a display device can only be used for anti-peeping display, and it will be limited when the user wants to share the information displayed on the display device (such as watching a video with multiple people). The display device where the light-emitting module provided by the embodiment of the present invention can switch between anti-peep display...

Abstract

The application discloses a light-emitting module, a control method thereof, and a display device, which belong to the field of display technology. The light-emitting module includes: a control unit, and a substrate divided into n partitions, n≥1, each of the n partitions is provided with: a first light-emitting unit and a second light-emitting unit, and the first light-emitting unit The light-emitting angle of the unit is smaller than the light-emitting angle of the second light-emitting unit; the control unit is used to: when each partition does not meet the preset condition, in the anti-peeping display mode, control the first light-emitting unit on each partition to emit light, And it is forbidden to control the second light-emitting unit on each partition to emit light; in the non-peep-proof display mode, control the second light-emitting unit on each partition to emit light. The present application solves the problem of low display flexibility of the display device. This application is for glowing.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a light emitting module, a control method thereof, 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 also visible to other people, so that the risk of leakage of user information is relatively high. [0003] In the related art, in order to reduce the risk of user information leakage, anti-peeping display technology is proposed, that is, by reducing the viewing angle of the display device, so that the information displayed on the display device can only be seen by the user facing the screen of the display device arrive. For example, a layer of anti-peeping film can be provided in ...
