Title: Capacity change detection circuit, touch panel, and judgment method
Inventor: YAMAUCHI KAZUTO
IPC: G01R27/26
Filed: 2008-10-08
Abstract: A detection circuit (1) includes: an input unit (2); two contact electrodes (A, B) which are connected to the input unit; phase inversion means (3) connected to the contact electrode (A); one amplification means (41) arranged in each contact means; and detection means (5A, 5B) which detect as an electric change amount, an amplitude change of an input signal caused by a capacity change in each of the contact electrodes (A, B). The detection circuit (1) causes the two electrodes to input signals having phases shifted by half frequency from each other by using the phase inversion means (3). When a contact occurs, the input pulse amplitude is amplified by the amplification means (41). The respective detection means (5A, 5B) detect signals of respective electrodes from the one amplified signal and output them to output units (6A, 6B), respectively.
