Abstract

The invention relates to the technical field of display, in particular to a backlight module and a display device. The backlight module comprises a light guiding plate and a light emitting assembly capable of emitting light rays and making the emitted light rays enter into the light guiding plate in a parallel mode; the light guiding plate further includes a light inlet surface, a bottom surface, a light outlet surface on the top and at least one oblique reflection surface, wherein the oblique reflection surface is positioned between the bottom surface and the light outlet surface, and the included angle between the oblique reflection surface and the plane, in the extension direction away from the light inlet surface, of the bottom surface is smaller then 90 degrees; the light inlet surface is positioned on one side of the light guiding plate. By the light emitting assembly, parallel light is emitted to the light inlet surface and reflected out of the light guiding plate by the oblique reflection surface, namely the light guiding plate does not need to be added with optical films, the condition that light is absorbed by the optical films is avoided, and the brightness of the parallel light emitted by the light guiding plate is not damaged; moreover, by not adding peep-proof protection films and other materials, the backlight assembly is much thinner.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. 【Background technique】 [0002] With the advancement of science and technology, portable mobile terminals such as computers and mobile phones have become the necessities of people's work and life. However, since the portable mobile terminal is often used in an open space or a public place, it is difficult to give consideration to privacy. [0003] At present, as far as the backlight module is concerned, the commonly used design is based on the light-controllable device installed on the light guide plate that emits parallel light, and the current light guide plate that emits parallel light is mainly to add 3M patent anti-peeping device to the ordinary light-emitting device and the light guide plate. Film products, and anti-peeping film-related products are used to realize parallel light output from the light guide plate, which has a lar...
