  • Patent number: 10817118
    Abstract: A display touch device includes a touch panel disposed on one side of a display panel and third patterned electrodes disposed on a supporting substrate. The touch panel includes a transparent substrate; first and second patterned electrodes respectively disposed on the transparent substrate in first and second direction. Mutual capacitors are formed between the first and second patterned electrodes, and the first and second patterned electrodes form a touch sensor structure. The first patterned electrodes or the second pattern electrodes partially overlap with the third patterned electrodes in a third direction to form a pressure sensor structure. The third direction is a stacking direction of the display panel and the touch panel. The touch sensor structure performs touch sensing in a first period of a frame and performs pressure sensing in a second period of the frame. The first period does not overlap the second period.

  • Publication number: 20190354219
    Abstract: A display device includes a first substrate, a second substrate, an icon sensor, a conductive material, and a first conductive pad. The second substrate is provided opposite the first substrate and has a display area and a non-display area. The icon sensor is provided on the first substrate and is disposed at least partially corresponding to the non-display area. The conductive material is provided between the first substrate and the second substrate. The first conductive pad is provided on the second substrate. The icon sensor is electrically connected to the first conductive pad on the second substrate through the conductive material.
