Abstract
Exemplary embodiments are disclosed of touchscreen devices for thermostats and other electronic devices. In an exemplary embodiment, a capacitive touchscreen device includes a touchscreen having touch regions. Each touch region is coupled with at least one first capacitor and at least one second capacitor. The second capacitors are connected in parallel and have smaller capacitance than the first capacitors. The capacitive touchscreen device may be configured to be operable in a standby mode in which the second capacitors are charged and an active mode in which the first capacitors are charged.
