Abstract
Provided are a touch panel and an input device. The touch panel includes a plurality of first touch pad groups disposed in a first direction and having a plurality of first touch pads disposed in the first direction and extending in a second direction. Here, the first touch pads disposed at the same position in the respective first touch pad groups are connected in common with a corresponding one of a plurality of first channels, a first input signal is applied to one of the first touch pads of each first touch pad group, and the first touch pads receiving the first input signal are connected with the first channels, respectively.
Claims75
A touch panel, comprising:
- a plurality of first touch pad groups disposed in a first direction and having a plurality of first touch pads disposed in the first direction and extending in a second direction,
- wherein the first touch pads disposed at the same position in the respective first touch pad groups are connected in common with a corresponding one of a plurality of first channels, a first input signal is applied to one of the first touch pads of each first touch pad group, and the first touch pads receiving the first input signal are respectively connected with the first channels.
A touch panel, comprising:
- a plurality of first electrodes disposed in a first direction and extending in a second direction;
- and
- a plurality of second electrodes each disposed between the first electrodes and extending in the second direction,
- wherein the second electrodes each have a plurality of touch pads disposed in the second direction and a plurality of connection pads connecting the touch pads, one end of each first electrode is connected with a first connection line, the first connection line is connected between a first transmission channel and a first reception channel, one end of each second electrode is connected with a second transmission channel, and the other end of each second electrode is connected with a second reception channel.
