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： 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.

摘要： A light source assembly, a backlight module, and a display device are provided in the field of display technology. The light source assembly includes a light source and a collimator. The collimator is arranged on a side of the light source where a light-emergent surface is located. When light emitted from the light source is incident on a preset surface of the collimator, a first included angle is formed between the light and the light-emergent surface. When the light is emitted out of the preset surface, a second included angle is formed between the light and the light-emergent surface. The first included angle is less than the second included angle, and the amount of light incident on per unit area of the preset surface is greater than a preset light amount threshold.
