Abstract:
(EN)
Provided are a capacitive sensing apparatus (200) and an electronic device (500). The capacitive sensing apparatus (200) comprises a sensor unit (22), a modulation unit (26), and a detection unit (24), wherein the sensor unit (22) comprises multiple first electrodes (222) and multiple second electrodes (224), and the multiple first electrodes (222) and the multiple second electrodes (224) are insulated from each other and are arranged in an intersecting manner; the modulation unit (26) is used for generating a modulation signal; and the detection unit (24) is used for receiving the modulation signal, and driving the sensor unit (22) to execute a sensing operation by providing an excitation signal for the multiple second electrodes (224), controlling the multiple first electrodes (222) to suspend sequentially, and providing a pre-set reference voltage signal for the first electrodes (222) which are not suspended. The electronic device (500) comprises the capacitive sensing apparatus (200) above.
(FR)
L'invention concerne un appareil de détection capacitive (200) et un dispositif électronique (500). L'appareil de détection capacitive (200) comprend une unité de capteur (22), une unité de modulation (26) et une unité de détection (24), l'unité de capteur (22) comprenant de multiples premières électrodes (222) et de multiples secondes électrodes (224), et les multiples premières électrodes (222) et les multiples secondes électrodes (224) sont isolées les unes des autres et sont agencées de manière croisée; l'unité de modulation (26) est utilisée pour générer un signal de modulation; et l'unité de détection (24) est utilisée pour recevoir le signal de modulation, et actionner l'unité de capteur (22) pour exécuter une opération de détection en fournissant un signal d'excitation pour les multiples secondes électrodes (224), pour commander les multiples premières électrodes (222) pour qu'elles soient suspendues de manière séquentielle, et pour fournir un signal de tension de référence prédéfini pour les premières électrodes (222) qui ne sont pas suspendues. Le dispositif électronique (500) comprend l'appareil de détection capacitive (200) susmentionné.
