摘要:
A device and method eliminates a shadowing effect on a touch input receiving device. The method includes receiving a touch input on a top layer that includes first conducting lines, a first current passing through the first conducting lines. The method includes determining a location of the touch input as a function of the first current passing through an intermediate layer as a second current to second conducting lines orthogonal to the first conducting lines of a bottom layer. The intermediate layer disposed between the top and bottom sides is configured as a resistive layer applying a resistance value to the first current upon the touch input being received. The first current continues through the first conducting lines along a remainder thereof as a third current after passing through the intermediate layer to eliminate the shadowing effect.
