Abstract
The present invention discloses a display with in-cell touch sensors comprising a first substrate, a second substrate, and a touch sensor disposed on the second substrate. A thin-film transistor (TFT) array is disposed on a surface of the first substrate, and a color pixel array is disposed on a surface of the second substrate. The TFT array faces and is aligned with the color pixel array. The touch sensor comprises a plurality of electrodes, a plurality of first leads, and a plurality of first pads. Each of the first leads is connected to one of the electrodes and one of the first pads. There are a plurality of second pads, a plurality of second leads, a plurality of connecting wires, and a plurality of terminal pads. Each of the second leads connects one of the second pads and one of the connecting wires. At least one of the connecting wires simultaneously and electrically connects several of the second leads. Each of the connecting wires electrically connects at least one of the terminal pads. Each of the first pads electrically connects one of the second pads.
