  • Patent number: 10001677
    Abstract: A touch display panel and a display apparatus are provided. The touch display panel includes: a first substrate, a second substrate, a common electrode layer, a touch electrode layer and a touch electrode wire layer. The common electrode layer is an entire piece of electrode; thus, respective display units may be ensured to have the same common voltage during a display driving, thereby solving the conventional problem of image flicker and non-uniform display of the display panel due to different common voltages in the respective display units caused by different resistances of the block-shaped electrodes in the common electrode layer. Moreover, the touch electrodes in the touch electrode layer are metal grid electrodes. Hence, the resistances of the touch electrodes are reduced and a touch sensitivity of the touch display panel is improved, while a high light transmittance of the touch display panel is ensured.

  • Patent number: 9711541
    Abstract: The present disclosure provides a display panel and a method for forming an array substrate of a display panel. The display panel includes an array substrate which includes a display region and a frame region. The frame region includes a wire region in which first signal wires are formed. Each of the first signal wires includes a first conductive layer and a second conductive layer which are stacked with each other and electrically connected. As such, to obtain the same resistance value as that in prior art, the first signal wires in the present disclosure can be formed with a reduced width. Therefore, the wire region of the array substrate can have a smaller size, and thus the whole frame region of the display panel can be smaller.
