Embodiment 1

[0042] Such as figure 1 , figure 2 and image 3 As shown, the present embodiment provides a backlight module, which includes: a first substrate 01 , a privacy-proof slot 02 and a first light emitting device 03 .

[0043] in, figure 1 A schematic structural diagram of the backlight module provided in this embodiment, figure 2 for figure 1 The cross-sectional view of the backlight module shown along the A-A' direction, image 3 for figure 2 Schematic diagram of the structure of the anti-peep groove. The anti-peeping groove 02 is disposed on the first substrate 01 , and the first light emitting device 03 is disposed in the anti-peeping groove 02 . The anti-peeping groove 02 has a plurality of side surfaces 021, and each side surface 021 has a first preset angle α with respect to the plane where the first substrate 01 is located. The first preset angle α satisfies: the light emitted by the first light emitting device 03 can The output is restricted within the preset vie...

Abstract

The invention provides a backlight module and a display device, and belongs to the technical field of display. The backlight module provided by the invention comprises a first base, a peep-proof groove and a first light-emitting device, wherein the peep-proof groove is arranged in the first base, and the first light-emitting device is arranged in the peep-proof groove; and the peep-proof groove isprovided with a plurality of side faces, each side face has a first preset included angle relative to the plane where the first base is located, and the included angle satisfies the condition that the light emitted by the first light-emitting device is limited within the preset visible angle range for outgoing. According to the technical scheme, by unitizing the side faces of the peep-proof groove, the light emitted by the first light-emitting device is limited within the visible angle range, so that people out of the visible angle range can not receive the light emitted by the first light-emitting device, and thus the anti-peeping function is realized.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a backlight module and a display device. Background technique [0002] With the development of science and technology, display devices such as mobile phones, notebooks, and tablet computers are more and more widely popularized and used. When people use these display devices in public places, for example, when they use these display devices to log in to accounts, read files, reply to messages, etc., the information displayed on the display devices may be seen by others, which makes the user's privacy unavoidable. to protection. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems in the prior art, and provides a backlight module and a display device, which use the side of the anti-peeping groove to limit the light emitted by the first light-emitting device within the range of viewing angles. People outside t...
