  • Publication number: 20170185224
    Abstract: A touchscreen device includes a touch surface, electrode pairs, a voltage applying portion, an output detecting portion, a correcting portion, and a specifying portion. The electrode pairs include a regular electrode pair and an irregular electrode pair. The voltage applying portion applies a driving voltage to the electrode pairs. The output detecting portion detects outputs from the regular electrode pair and the irregular electrode pair in response to the driving voltage. The correcting portion corrects the output from the irregular electrode pair to amplify the output from the irregular electrode pair to the same level as the output from the regular electrode pair. The specifying portion specifies the electrode pair having the capacitance that is defined as varied based on the output from the regular electrode pair and the output from the irregular electrode pair.

  • Patent number: 9218098
    Abstract: A conducting layer (7) is formed in a shape of a grid having a predetermined width of lines extending along the first direction (horizontal direction in the drawing) and the second direction (vertical direction in the drawing). In a region that, when seen in planar view, overlaps those lines of the conducting layer (7) which extend along the first direction, lines of an insulating light-blocking layer (6) that are wider than those of the conduction layer (7) are arranged at predetermined intervals along the second direction. The conducting layer (7) is broken at predetermined places in a region that overlaps the insulating light-blocking layer 6 when seen in plane view. This makes it possible to achieve a liquid crystal display device including a touch panel substrate that has a high aperture ratio and that can suppress leakage of light through cuts in a conducting layer.
