  • Publication number: 20160357312
    Abstract: An In Cell touch panel and a display device are disclosed. The insulating layer comprises at least one groove at overlapping regions between each self capacitance electrode and the wires. Via holes penetrating the insulating layer are arranged in the insulating layer at overlapping regions between corresponding wires and self capacitance electrodes. Recesses not penetrating the insulating layer are arranged in the insulating layer at overlapping regions between wires and self capacitance electrodes apart from the corresponding wires and self capacitance electrodes. Thus, only the corresponding wires and self capacitance electrodes are electrically connected with each other, and the insulating layer is further provided with grooves at overlapping regions between wires and self capacitance electrodes which are not electrically connected.

  • Publication number: 20160357283
    Abstract: The present invention discloses a touch display panel, a detecting method thereof, and a display device. The common electrode layer is divided into a plurality of independent self capacitance electrodes, and the common electrode is multiplexed as self capacitance electrodes. There is no need to provide an additional film, and it is only required to modify the pattern of the common electrode layer in the current LCD panel. Thus, the production cost is reduced, and the production efficiency is improved. Since the self capacitance electrodes are formed by dividing the common electrode layer in the above-mentioned touch display panel, a compensating electrode is further provided which is arranged in a layer different from that of the self capacitance electrodes, is insulated from the self capacitance electrodes, and at least covers a portion of a partition gap between neighboring self capacitance electrodes. A common electrode signal is applied to the compensating electrode during a display period.

    Abstract: An in-cell touch screen and a display device are provided. In the in-cell touch screens, an insulation layer, in an area that each self-capacitance electrode overlap a wire, is provided with at least a first hole that runs through the insulation layer and each self-capacitance electrode is electrically connected with a corresponding wire via a corresponding first via hole; each self-capacitance electrode, within an area overlapping other wire than the corresponding wire and at a position corresponding to the first via hole, is disposed with a second via hole that runs through the self-capacitance electrode. An orthogonal projection of a second via hole on a lower substrate covers an orthogonal projection of a first via hole on the lower substrate. The in-cell touch screen can solve a problem of uneven image display due to nonuniform distribution of via holes in an insulation layer.
