Abstract

Light-guiding panel, backlight module, and a display device are provided. An exemplary light-guiding panel includes a light-guiding body and a light diffusing-transmitting layer over the light-guiding body. The light-guiding body is configured to reflect incident light beams on a first side surface of the light-guiding body, thereby providing reflected light beams to the light diffusing-transmitting layer. The light diffusing-transmitting layer is capable of diffusing and transmitting the reflected light beams.

Description

technical field [0001] The invention relates to the field of displays, in particular to a light guide plate, a backlight module and a display device. Background technique [0002] A display device with an adjustable viewing angle can provide different display viewing angles to meet different viewing needs of users. For example, a display device with an adjustable viewing angle can provide two modes of private viewing and normal viewing. Private viewing refers to the viewing angle of the display device is narrow enough to avoid being seen by people around, and normal viewing refers to the viewing angle of the display device. Wide enough for viewing with a wide enough viewing angle. [0003] This display device with adjustable viewing angle usually includes a backlight module, a switchable diffuser and a display panel arranged in sequence; the backlight module is used to provide backlight for the display panel; the switchable diffuser can be in a transparent state When in th...
