碩士 === 國立臺灣科技大學 === 電子工程系 === 97 === “Sensors” have been important components in industrial and automation application field recently, including temperature sensor, moisture sensor, pressure sensor, magnetic sensor, Lux sensor and distance sensor. Due to the demand for mobile devices and products which have LCD panel are still growing up, so such as lux sensor (visible light sensor) will start more popular in this application field in the future. The main function of visible light sensor is to provide environment light intensity information to ASIC in order to adjust panel brightness dynamically. In this research, the main purpose is to evaluate and study the feasibility of visible light sensor (400~700nm) which is using photo transistor die. The topics will focus on sensor response spectrum, infrared and UV interference, package and application design.
