1. A touch sensitive device including a plurality of display pixels, the touch sensitive device comprising:
- a color filter layer;
a first ITO layer, the first ITO layer containing circuit elements that can be configured to operate as both touch hardware and display hardware;
a TFT layer;
a liquid crystal layer disposed between the TFT layer and the color filter layer; and
a second ITO layer, the second ITO layer disposed above the color filter layer.

Abstract
Integrated touch screens are provided including drive lines formed of grouped-together circuit elements of a thin film transistor layer and sense lines formed between a color filter layer and a material layer that modifies or generates light. The common electrodes (Vcom) in the TFT layer can be grouped together during a touch sensing operation to form drive lines. Sense lines can be formed on a separate layer dedicated to only touch hardware.
