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.
