INFORMATION TERMINAL USING ANTENNA AS LIGHT PEN

摘要

PURPOSE: An information terminal using an antenna as a light pen is provided to semi-permanently use a power supply of a light source applying light to an optical detection display device and prevent loss of the antenna used as the light pen. CONSTITUTION: A main body(100) is equipped with a PCB(110) forming power supply ports(114,116) receiving power from the power supply and mounted with driver devices generating various driving signal, and is joined with the power supply. An optical detection display device includes pixels for displaying the image, and detecting elements arranged among the pixels and outputting a detection signal by the light applied from the outside, and is installed to the main body. The antenna(300) is attached to the main body and forms a connector at one end. A light generator(400) is combined to another end of the antenna and applies the light to the detection element by electrically connecting to the power supply. A connection cable(500) electrically connects to the power supply ports with the light generator and connects to the main body with the antenna.
