  • Patent number: 10761640
    Abstract: According to one embodiment, a display device includes first electrodes overlapping a display area, a cover base covering the display area and a frame area, a second electrode arranged in the cover base and overlapping the frame area, a touch detection driver configured to output a drive signal to the second electrode, and a level shifter arranged between the second electrode and the touch detection driver, and configured to increase a signal level of the drive signal and output the drive signal having the increased signal level to the second electrode. The touch detection driver is configured to detect contact or proximity to an object with the frame area based on electrostatic capacitance between the first electrodes and the second electrode.

  • Patent number: 10592025
    Abstract: According to one embodiment, a display device includes a display panel including a first substrate including a display area and a first detection electrode, and a second force sensing electrode opposing the display area and the first detection electrode with a gap therebetween. The second force sensing electrode includes a central portion opposing a central portion of the display region, a peripheral portion located to surround the central portion and a reinforcing structure which reinforces the peripheral portion, and the gap between the central portion and the first detection electrode is greater than a gap between the peripheral portion and the first detection electrode.

  • Patent number: 10579196
    Abstract: A display device includes a first substrate, a plurality of first electrodes, a second electrode, a third electrode, and a driver. The first electrodes are disposed in a display region of the first substrate. The second electrode faces the first electrodes in a direction perpendicular to the surface of the first substrate and forms capacitance between the second electrode and the first electrodes. The third electrode is provided in a peripheral region positioned on the outside of the display region and does not overlap the first electrodes in planar view. The driver supplies a drive signal to the third electrode and at least one of the first electrodes simultaneously.

  • Patent number: 10564754
    Abstract: A display device includes a display panel, a housing, a second electrode, and a driver. The display panel includes a substrate and a plurality of first electrodes arrayed in a display region of the substrate. The housing has at least a pair of walls facing each other in planar view and is provided with the display panel between the pair of walls. The second electrode is provided to the housing and positioned on the outer side than the display region in planar view and forms capacitance between the second electrode and the first electrodes. The driver supplies a drive signal to the second electrode.

  • Patent number: 10540038
    Abstract: A display device includes a substrate, a plurality of first electrodes, a plurality of second electrodes, at least one third electrode, and a drive circuit. The first electrodes are arrayed in an active area of the substrate. The second electrodes face the first electrodes and form capacitance between the first electrodes and the second electrodes. The third electrode is provided in a peripheral region positioned on the outside of the active area. The drive circuit supplies a drive signal having a phase determined based on a predetermined code to the first electrodes and the third electrode.
