PANEL TYPE CAMERA, OPTICAL TOUCH SCREEN AND DISPLAY APPARATUS EMPLOYING THE SAME

摘要

PURPOSE: A panel-type camera, and an optical touch screen and a display device employing the same are provided to work as a UI(User Interface) by having a near/far photographing function as well as a touch sensing function. CONSTITUTION: A lens panel(20) comprises narrow angle lenses(21) two-dimensionally arranged. An optical detection panel(30) receives lights, which pass through the narrow angle lenses from outside, through optical detectors(31) two-dimensionally arranged corresponding to the narrow angle lenses and obtains a far image. Each narrow angle lens comprises a micro lens(23) having a transparent conical body, a light guide(25) connected to the transparent conical body, and a cladding unit(27) surrounding the transparent conical body and the light guide.
