Abstract
A driving system is operatively associated with a light emitting array that includes a plurality of scan lines, a plurality of channel lines and a plurality of light emitting elements. The driving system includes a voltage converter circuit and a driver circuit. The voltage converter circuit converts, based on a control signal, an input voltage into an output voltage that has a magnitude related to the control signal. The driver circuit drives the light emitting elements via the scan lines and the channel lines, is operable, based on voltages at the channel lines, to pull or not to pull a voltage at a common node to a logic level, and generates the control signal based on the voltage at the common node.
