The invention discloses a capacitive touch light-regulating switch comprising an AC-DC isolation switch power supply circuit, a capacitive sensing processing circuit, an AC zero-cross detection circuit and a microprocessor integrated information processing circuit. Capacitive sensing input is formed by the capacitive sensing processing circuit and acts as the light regulation control input of the microprocessor integrated information processing circuit. The AC-DC isolation switch power supply circuit is mainly responsible for supplying power to the microprocessor integrated information processing circuit, the capacitive sensing processing circuit and the AC zero-cross detection circuit. The AC zero-cross detection circuit acquires an accurate control signal via combination of an operational amplifier and an optical coupler. Time processing of turn-on and turn-off of a triggering signal of the capacitive sensing processing circuit and the control signal of the AC zero-cross detection circuit is realized by the microprocessor integrated information processing circuit so that so that turn-on time of a lamp is controlled and thus brightness of the lamp is changed. The input is based on the capacitive sensing principle so that the capacitive touch light-regulating switch has advantages of being long in the service life, high in safety coefficient and great in waterproof and dustproof effect.

The invention discloses a touch structure, a touch detection method and a touch display device. The touch structure is internally provided with a first strip electrode and a second strip electrode, which are intersected and are arranged in different layers, wherein the first strip electrode comprises a first strip sub-electrode and a second strip sub-electrode which are in mutual isolation and are arranged in the same layer. When the touch structure is adopted to perform touch detection, in an initial detection mode, the first strip sub-electrode is taken as a touch drive electrode and the second strip sub-electrode is taken as a touch detection electrode, so that touch detection is realized when only the single-layer touch electrode is in an operating state; when touch is detected under the initial detection mode, a fine detection mode can be started, the second strip sub-electrode is taken as a touch drive electrode and at least part of the first strip electrode is taken as a touch detection electrode; or the second strip electrode is taken as a touch detection electrode and at least part of the first strip electrode is taken as a touch drive electrode, so that fine detection on the touch position is realized.
