Abstract
A touch detection method is applied to a touch panel including sensing units and includes: detecting sensing values corresponding to the sensing units; selecting a first sensing value that is a local maximum among the sensing values; determining a first sensing unit corresponding to the first sensing value among the sensing units; selecting from the sensing units a second sensing unit located at the first side of the first sensing unit; selecting from the sensing values a second sensing value corresponding to the second sensing unit; and generating a touch coordinate according to the first sensing value, the second sensing value, a touch sensing value distribution model, and the coordinate of the first sensing unit.
