TOUCHPAD AND METHOD FOR SENSING TOUCH USING THE SAME

摘要

PURPOSE: A touchpad and a method for sensing touch position are provided to exactly detect a touch position by grouping a conduction plate and detecting a touch point based on the center point of the group. CONSTITUTION: A signal generator(120) generates electricity of a predetermined pattern. Conduction plates(220) are arranged having a predetermined gap in order not to be touched with each other. Electric signal is applied to the conduction plates by the touch of a user(140). A signal detection unit(300) detects the contact position of the conduction plate based on the touch point information and the strength of the electric signal.
