摘要： A touch panel includes a cover lens located at top of the touch panel, plural touch sensor units, and plural sensing channels. The touch sensor units are disposed below the cover lens and arranged in rows and columns. The touch sensor units are disposed on the sensing channels. Each of touch sensor units acquires a sensing magnitude for identifying a position of the cover lens that touched by the stylus according to signals outputted by the sensing channels. The sensing magnitude of one of the touch sensor units is composed of the signals of the adjacent sensing channels located within a vertical projection of the one of the touch sensor units.

摘要： A touch panel includes a first electrode layer and a second electrode layer. The first electrode layer has transmitting electrodes arranged in transmitting channels and traces respectively coupled to the transmitting channels. The second electrode layer has receiving electrodes arranged in receiving channels. At least one of the traces, the transmitting channels and one of the receiving channels in proximity of the traces form touch detection blocks that respectively correspond to the transmitting channels. For each touch detection block, in a circle area overlapped with at least one of the traces and substantially in the touch detection block corresponding to one of the transmitting channels, a summation of areas of the corresponded transmitting channel and the trace coupled to the corresponded transmitting channel is substantially larger than a summation of areas of the other transmitting channels and the other traces.

摘要： A knob device is applicable to a touch panel. The knob device includes a knob cover, a plurality of sensing pads and a rotation sensing element. The plurality of sensing pads are fixedly arranged on the touch panel. A gap is form between two sensing pads. The plurality of sensing pads and gaps are distributed in a ring area around a center of an orthographic projection of the knob cover. The rotation sensing element is connected to the knob cover. When the knob cover is turned to be rotated, the rotation sensing element is rotated synchronously. When a user touches the knob device and the rotation sensing element overlaps one of the plurality of sensing pads, the touch panel generates a rotation sensing signal in response to a location of the rotation sensing element.
