Abstract

The present invention provides for a liquid crystal display device with a signal layer integrated onto a substrate. Circuitry derives touch position based upon response to signals applied to the signal layer. At least one resistor is integrated onto the substrate. The resistor is coupled between the signal layer and the circuitry. The resistor is formed in conjunction with the signal layer. Preferably, the resistor is part of a resistor network for linearizing resistance of the signal layer in a vertical direction and horizontal direction.
