Abstract: A LED driver comprises two output contacts (310, 311) and an additional contact (312) which enables detection of connection of the LED driver to a LED module (301). The LED driver has a normal current regulating mode and an open circuit protection voltage regulating mode. The LED driver is switched from the voltage regulating mode to the current regulating mode in response to the detection of connection of the LED module. This enables a LED module to be connected to the LED driver while it remains powered, in particular because the LED driver is placed in a voltage regulating mode prior to connection to the LED module.

Abstract: An electronic device operating based on a touch input includes a touch screen for receiving the touch input; and a controller for determining a pressure state corresponding to the touch input, when the pressure state satisfies a first pressure condition, controlling the touch screen to display information relating to the touch input, and, when the pressure state satisfies a second pressure condition, performing a function corresponding to the touch input. A method of controlling an electronic device based on a touch input includes determining a pressure state of a touch input; when it is determined that the pressure state satisfies a first pressure condition, displaying information relating to the touch input; and when it is determined that the pressure state satisfies a second pressure condition, performing a function corresponding to the touch input.
