Publication number: 20110273403Abstract: A photo-sensing LCD touch device with a light guide plate is provided. The light guide plate is disposed in an LCD touch panel, and a light source is disposed on one side of the light guide plate to provide lights into the light guide plate, yielding an occurrence of total reflection of the lights in the light guide plate. When a touch object touches the light guide plate, the total reflection of the lights would be decomposed so that the lights are emitted out of the light guide plate. Therefore, a photo-sensor can detect a variance of a photo-current of the scattered lights to accurately determine a touched position. Accordingly, the LCD touch device would not rely on ambient light and can avoid a drawback of an undesirable shadow.Type: ApplicationFiled: August 11, 2010Publication date: November 10, 2011Applicant: CHUNGHWA PICTURE TUBES, LTD.Inventors: Yi-ling Hung, Heng-chang Lin
