Abstract: A capacitive touch panel has a plurality of traces including a boundary trace, and a virtual trace is defined outward of the boundary trace and assigned with a virtual coordinate and a virtual capacitance for interpolation to position a touch point around the boundary of the capacitive touch panel, thereby eliminating the non-addressable region of the capacitive touch panel.

Abstract: A detect method of a capacitive touch panel alternately senses the traces of the capacitive touch panel to generate two series of fields, interpolates with the first fields to obtain interpolation fields having temporal coordinates identical to that of the second fields, and combines the second fields and the interpolation fields to generate reconstructed frames for coordinate calculation. Therefore, the capacitance sensing sequence of the traces is scheduled in a multi-field way to reduce the operation of the detector circuit of the capacitive touch panel.
