    TSP - Touch Screen Panel

     

     

    ■ Melfas Mutual Capacitance TSP

     

    After patternizing the electrically conductive FILM or the transparent electrically conductive film between and allocate a lot of independent electrodes, So when the capacitance couple is used either human bodies or the films which formed electrode matrix.


    When the finger touches the electrode, the capacity of the human body is added to the circuit, and the pointing location of the pointing is detected by monitoring the changed capacity.

    MELFAS’s capacitive Touch Screen is made by coating Capacitive Touch Screen which went through the heat treatment with transparent metal(ITO) of the special electrical conductivity.


    The layer with the horizontal pattern and the vertical pattern is to be produced. (In case of the 2 layers) By overlapping the two layers together, we compose the matrix. We calculate the matrix touched the finger and recognize it. Using a specialized pattern of MELFAS(2 layer or 1 layer), we recognize the changed amount of the capacitor value and then extract the coordinate value(pattern figure: registered patent)
