OPTICAL SENSOR

摘要

PURPOSE: An optical sensor is provided to flow a same photocurrent unrelated to an area of infrared light and a visible ray sensing transistor, and maximize a sensing range of the optical sensor. CONSTITUTION: A visible light sensor includes a visible light sensing transistor(Tv). An infrared sensor includes an infrared sensing transistor(Ti). The visible light sensing transistor receives first driving voltage through a first driving voltage line. The infrared sensing transistor receives second driving voltage through a second driving voltage line. The visible light and the infrared sensing transistor receive reference voltage through a reference voltage line.
