    摘要： An interface device includes an electronic device and an input device for communicating with the electronic device. The electronic device includes a display layer, a sensor layer, and a controller for outputting a first uplink signal and a second uplink signal to the sensor layer. The input device includes a communication unit for receiving an uplink signal from the sensor layer, a memory for storing first information and second information, a signal determination unit for determining whether the uplink signal is the first uplink signal or the second uplink signal, based on the first information and the second information, and a signal conversion unit for outputting conversion data in response to the uplink signal being the second uplink signal.

    摘要： Disclosed are an input sensing unit and a display device including the input sensing unit. The input sensing unit includes a first sensing electrode extending in a first direction, a second sensing electrode extending in a second direction and insulated from the first sensing electrode, a first pen sensing electrode extending in the first direction and including a 1-1st pen sensing electrodes and a 1-2nd pen sensing electrode disposed on different layers and overlapping each other, and a second pen sensing electrode extending in the second direction and including a 2-1st pen sensing electrodes and a 2-2nd pen sensing electrode disposed on different layers and overlapping each other. The 1-1st pen sensing electrode is disposed adjacent to the first sensing electrode on the same layer, and the 2-1st pen sensing electrode is disposed adjacent to the second sensing electrode on the same layer.

    摘要： A display device includes a display panel, a fingerprint sensing part, and a cover panel. The fingerprint sensing part is covered by the display panel. The cover panel is covered by the display panel and includes a metal layer. The metal layer includes a first metal layer and a second metal layer. The first metal layer surrounds the fingerprint sensing part in a plan view. The second metal layer extends from the first metal layer and is disposed between the display panel and the fingerprint sensing part.
