  • Display device
    Patent number: 11899866
    Abstract: A display device includes a display panel, a plurality of first sensing electrodes disposed on the display panel, and a plurality of second sensing electrodes disposed on the first sensing electrodes and isolated from the first sensing electrodes. A wire width of each first sensing electrode of a second group is smaller than a wire width of each first sensing electrode of a first group, and a wire width of each second sensing electrode of a fourth group is smaller than a wire width of each second sensing electrode of a third group.
    Type: Grant
    Filed: September 10, 2021
    Date of Patent: February 13, 2024
    Assignee: SAMSUNG DISPLAY CO., LTD.

  • Electronic device and interface device having sensor layer capable of operating in two modes
    Patent number: 11609654
    Abstract: An interface device includes an electronic device and an input device for communicating with the electronic device, wherein the electronic device includes a display layer, a sensor layer which is disposed on the display layer and senses a first input by the input device, a display driving unit for generating a vertical synchronization signal for driving the display layer, and a control unit for controlling the sensor layer, wherein the control unit outputs, in synchronization with a first vertical synchronization signal, a first uplink signal to the sensor layer and outputs, in synchronization with a second vertical synchronization signal, a second uplink signal having a phase different from a phase of the first uplink signal to the sensor layer.
