Abstract
A touch panel and a touch device with the touch panel are provided. Each of plurality of touch electrodes of a substrate of the touch panel is led by a corresponding one of plurality of touch wires, and each row and each column of the plurality of touch electrodes share one detection channel through a corresponding one of the plurality of touch wires, and can detect a touch signal sensed by each of the plurality of touch electrodes, thereby increasing an area of the touch panel that can detect the touch signal, and enhancing a detection accuracy and a linearity of the touch panel.
Claims20
A touch panel, comprising:
- a substrate;
- a plurality of touch electrodes overlapping the substrate and comprising one or more first touch electrode members extending in a row direction and arranged in a column direction different from the row direction and one or more second touch electrode members extending in the column direction and arranged in the row direction;
- a plurality of touch wires overlapping the substrate, wherein each of the first touch electrode members and the first touch electrode members is connected to a corresponding one of the plurality of touch wires;
- and
- a plurality of detection channels disposed outside the substrate, wherein each first touch electrode member and at least one other first touch electrode member of the first touch electrode members are connected to a same one of the plurality of detection channels through the touch wire.
A touch device comprising an active stylus and a touch panel, the touch panel is configured to detect a touch signal from the active stylus, the touch panel comprising:
- a substrate;
- a plurality of touch electrodes overlapping the substrate and comprising one or more first touch electrode members extending in a row direction and arranged in a column direction different from the row direction and one or more second touch electrode members extending in the column direction and arranged in the row direction;
- a plurality of touch wires overlapping the substrate, wherein each of the first touch electrode members and the first touch electrode members is connected to a corresponding one of the plurality of touch wires;
- and
- a plurality of detection channels disposed outside the substrate, wherein each first touch electrode member and at least one other first touch electrode member of the first touch electrode members are connected to a same one of the plurality of detection channels through the touch wire.
