45.1: Touch Panel Embedded IPS‐LCD with Parasitic Current Reduction Technique

A capacitive-type touch-panel-embedded IPS-LCD is realized by novel parasitic current reduction technique (PCR). The PCR removes 90% of the current flowing through the parasitic capacitance on a capacitive sensor (ITO layer) formed on a color filter substrate. Since the IPS-LCD has the same structure as commercial products, it features no reduction in aperture ratio.
