Capacitively actuated touch sensor units are integrated between subpixel light emitters of a liquid crystal display panel. In one embodiment, a sensor unit is monolithically integrated on a same substrate as are a plurality of associated subpixel units and the sensor unit includes a variable capacitor and a reference capacitor connected to define a voltage splitting circuit having a split voltage generating node. The sensor unit also includes a sensing transistor operatively coupled to the split voltage generating node and a voltage resetting transistor operatively coupled to the split voltage generating node. In one embodiment, one plate of the variable capacitor is defined by a touchwise flexed portion of a common electrode of the display and an opposed plate is defined by a spaced apart facing electrode provided on a TFT array substrate of the liquid crystal display.
