Abstract: A method for manufacturing a light-absorbing film is provided, where the light-absorbing film absorbs external light incident on a reflection surface of a reflection-type screen. The method includes forming a dye layer by spreading dye, including a light absorbing material, on a surface of a first transparent film, laminating a second transparent film on the dye layer, forming a cylindrical film roll by winding the first and second transparent films, laminated on the dye layer, around a core, and forming a film member by slicing the film roll along a direction that is inclined with respect to a radial direction of the film roll.

Abstract: Provided is a touch recognition device and a display apparatus using the same. The touch recognition device includes: an image screen configured to display an image; a light source configured to emit light toward the image screen; a camera provided in the rear of the image screen and configured to detect at least one of infrared reflected and input from an object approaching or contacting the image screen; and a diffusion transmitter provided between the image screen and the camera, configured to diffuse the emitted light in response to the light source emitting the light, and configured to transmit the infrared in response to the light source emitting no light.

Abstract: A screen for a Fresnel type front projection apparatus is provided. The screen includes a reflective layer including a plurality of reflective protrusions which project toward a front of the screen; each of the plurality of reflective protrusions including a reflective surface which forwardly reflects an image light projected from a projector; and an absorbing surface which absorbs an external light. The reflective surface includes a first region on an inner side thereof on which a reflective coating is not formed and a second region on an outer side thereof on which the reflective coating is formed.
