摘要： A backlight assembly includes a light guide plate, containing a plurality of dots. Each dot includes a first reflecting surface and a second reflecting surface, respectively configured to reflect a first incident light such that reflected light emerges in a first preset direction in a narrow viewing angle mode, and to diffusely reflect a second incident light such that the reflected light emerges dispersedly in a wide viewing angle mode. A first light source can be disposed over a lateral side of the light guide plate and facing the first reflecting surface, to provide the first incident light on the first reflecting surface in the narrow viewing angle mode. A second light source can be disposed over another lateral side of the light guide plate and facing the second reflecting surface to provide the second incident light on the second reflecting surface in the wide viewing angle mode.

摘要： A side-type backlight module includes a light guide plate and a reverse prism sheet that are stacked. The reverse prism sheet includes a first prism. A surface of the first prism proximate to the light guide plate includes a plurality of prism structures substantially parallel to each other. Each prism structure protrudes toward a direction approaching the light guide plate. A surface of the light guide plate proximate to the reverse prism sheet includes a plurality of strip-shaped microstructures substantially parallel to each other. Each strip-shaped microstructure protrudes toward a direction approaching the reverse prism sheet. An extending direction of the prism structure crosses an extending direction of the strip-shaped microstructure.

摘要： The present disclosure provides a floating touch camera module, a display device and a touch method. The floating touch camera module includes: a lens with a light collection surface and a light emitting surface; an image sensor at one side of the light emitting surface of the lens, the image sensor configured to receive light rays from the lens and form sensing information; and an infrared cut filter film at one side of a light incident surface of the image sensor and configured to filter out infrared light rays. The infrared cut filter film is movable relative to the lens between a first position at which the infrared cut filter film directly faces the lens and a second position at which the infrared cut filter film is offset from the lens, thereby enabling the floating touch camera module to switch between a photographing mode and a touch mode.
