    MCS - Melfas Chip Solution

     

     

    ■ Product Introduction

     

    The Self-Capacitance is the method to judge the touch location by detecting the capacitance (Ct) which is produced between the contact object such as a finger and the sensing electrode within the touch panel without applying any additional driving signal for the recognition of the touch input. That is to say, once the part of a body contacts the touch sensor, the capacitance is produced in between the contacted body and the sensing electrode.
    The sensing circuit which is electrically connected to the touch sensor detects whether there is a contact and the contact area, etc. in the touch sensor by providing the electric charge for the touch sensor and measuring the voltage (or current) accordingly.
