US Patent 8487890 In-cell touch-sensitive panel

An in-cell touch-sensitive panel includes TFT and CF substrates. The TFT substrate includes a net-shaped readout circuit and conductive pads arranged in array manner. The net-shaped readout circuit includes widthwise and lengthwise readout lines. The widthwise readout lines are electrically connected to the lengthwise readout lines. The conductive pads are electrically connected to the net-shaped readout circuit. Spacers are adapted to keep a first gap between the TFT and CF substrates. Protrudent portions are arranged to be corresponding to the conductive pads, and there is a second gap between the protrudent portion and the conductive pad. A transparent electrode covers the spacers and the protrudent portion.
