flexible tactile sensor equipped with an integrated touch-screen display and its recognition algorithm implementation

摘要

A display-integrated touch screen having a tactile sensor and a recognition algorithm realizing method thereof are provided to measure not only the contact position but also the contact force through the combination of signals obtained from a plurality of tactile sensors. A plurality of tactile sensors(30) are arranged between a lower substrate and a display(20). From the electric capacity or contact resistance generated from the tactile sensors, a display-combined touch screen detects the contact position, contact force and multi-touch. The tactile sensors are arranged in the matrix form of a plurality of rows and columns.
