  • Publication number: 20140118279
    Abstract: A touch display screen and a touch display apparatus are disclosed. The touch display screen comprises: an array substrate and a color film substrate disposed box to box; a group of first electrode lines disposed on the array substrate or the color film substrate; a group of second electrode lines disposed on the array substrate or the color film substrate and arranged as crossing the group of first electrode lines; a conductive shielding layer with high-resistance transparency, disposed on the color film substrate and located above the group of first electrode lines and the group of second electrode lines. Because the resistance value of the conductive shielding layer with high resistance and transparency is high, a projected field signal between the first electrode lines and the second electrode lines may pass through the conductive shielding layer to ensure a realizability of touch operations.

  • Publication number: 20140104510
    Abstract: The present invention discloses a capacitive in cell touch panel and display device, wherein touch sensing electrodes are provided on a color filter substrate, the whole common electrode layer of the TFT array substrate is segmented into a plurality of strip-shaped structures functioning as touch driving electrodes, and the touch driving electrodes are driven in a time-sharing manner to achieve the touch function and the display function in a time-sharing manner.
