Abstract:
(EN) Disclosed are a detection unit (24), a capacitive sensing apparatus, and an electronic device. The detection unit (24) is used for being connected to a sensor unit. The sensor unit comprises a plurality of first electrodes (222) and a plurality of second electrodes (224). The plurality of first electrodes (222) and the plurality of second electrodes (224) are arranged in an intersecting and insulating manner. The detection unit (24) comprises: a plurality of first switches; a reference circuit (240) connected to the plurality of first electrodes (222) by means of the plurality of first switches, and providing a pre-determined reference voltage signal to the plurality of first electrodes (222); a signal reading circuit (244) for providing excitation signals to the plurality of second electrodes (224), and receiving sensing signals output by the second electrodes (224); and a control circuit (242). When the detection unit (24) drives the sensor unit to execute a sensing operation, the control circuit (242) controls the plurality of first electrodes (222) to suspend successively by means of controlling the plurality of first switches to disconnect successively. The capacitive sensing apparatus comprises the detection unit (24). The electronic device comprises the capacitive sensing apparatus.
(FR) L'invention concerne une unité de détection (24), un appareil de capture capacitif et un dispositif électronique. L'unité de détection (24) est destinée à être connectée à une unité à capteurs. L'unité à capteurs comprend une pluralité de premières électrodes (222) et une pluralité de secondes électrodes (224). La pluralité de premières électrodes (222) et la pluralité de secondes électrodes (224) sont agencées de manière à se croiser et à être isolées. L'unité de détection (24) comprend : une pluralité de premiers commutateurs ; un circuit de référence (240) connecté à la pluralité de premières électrodes (222) au moyen de la pluralité de premiers commutateurs et fournissant un signal de tension de référence prédéfini à la pluralité de premières électrodes (222) ; un circuit de lecture de signaux (244) prévu pour fournir des signaux d'excitation à la pluralité de secondes électrodes (224) et recevoir des signaux de capture émis par les secondes électrodes (224) ; et un circuit de commande (242). Lorsque l'unité de détection (24) amène l'unité à capteurs à exécuter une opération de capture, le circuit de commande (242) commande la pluralité de premières électrodes (222) pour qu'elles s'interrompent successivement en commandant la pluralité de premiers commutateurs pour qu'ils se déconnectent successivement. L'appareil de capture capacitif inclut l'unité de détection (24). Le dispositif électronique comprend l'appareil de capture capacitif.
