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 touch system includes channel electrodes that are mapped to touch pixels such that a number of the channel electrodes in each dimension is lower than a number of the touch pixels in said dimension. In one embodiment, each channel electrode has different adjacent channel electrodes at different positions of the mapped touch pixel. In another embodiment, each touch pixel in said dimension is laterally extended to at least one adjacent touch pixel in said dimension. In a further embodiment, original sensing channel electrodes and mirrored sensing channel electrodes are alternately corresponded to the driving channel electrodes.
