Abstract:
1. A capacitive touch device capable of avoiding a reduced frame rate, comprising: a touch panel comprising a plurality of first sensing lines and a plurality of second sensing lines; and a plurality of touch detection units at least comprising a first touch detection unit and a second touch detection unit, the first touch detection unit electrically coupled to the first sensing lines and the second touch detection unit electrically coupled to the second sensing lines, wherein at least a last one of the first sensing lines is further electrically coupled to the second touch detection unit, and at least a first one of the second sensing lines is further electrically coupled to the first touch detection unit, and a position POS_RX of a touch between the last one of the first sensing lines and the first one of the second sensing lines is calculated according to a sensed value corresponding to a first sensing line prior to the last one of the first sensing lines, a sensed value corresponding to the last one of the first sensing lines and a sensed value corresponding to the first one of the second sensing lines, wherein the position POS_RX of the touch is calculated according to the following equation:  wherein POS
