Abstract
A current driving digital pixel apparatus including a power rail, a common rail, a micro light emitting device, and a current driver is provided. The power rail is configured to supply a source current. The micro light emitting device is electrically coupled to the common rail. The current driver includes a first switching device electrically coupled to the power rail and a current mirror device electrically coupled between the first switching device and the micro light emitting device. The current mirror device receives the source current from the power rail through the first switching device and supplies a current to the micro light emitting device. The first switching device is a low voltage device and the current mirror device is a medium voltage device.
