TOUCH PANEL SENSOR, FOR SENSING THE ACCESS LOCATION OF A PHYSICAL BODY THROUGH THE VARIATION OF CAPACITANCE VALUES

摘要

PURPOSE: A touch panel sensor is provided to reduce the use of an insulating sheet by directly forming an electrode pattern on a glass substrate.;CONSTITUTION: A blocking unit(140) on a glass substrate(110) blocks the penetration of normal light. Plural micro metal patterns(112) senses the access of a physical body. A metal electrode terminal is electrically connected with the plural micro metal patterns. The metal electrode terminal is electrically connected with an external circuit board(101). A transparent electrode pattern(122) of a lower sheet(120) is electrically insulated with the micro metal pattern and the metal electrode terminal. Through the variation of the capacitance value of an intersection with the micro metal pattern, the lower sheet senses the access of the physical body.;COPYRIGHT KIPO 2010
