Abstract
A current driving circuit includes a first terminal electrically connected to a voltage source, a second terminal grounded, a signal line through which a signal current runs, a first switch, a second switch electrically connected to the signal line and further electrically connected in series to the first switch, a third switch electrically connected to the first terminal, a memory stage converting the signal current into a voltage and stores the voltage therein, a driving transistor, a load electrically connected between a source of the driving transistor and the second terminal, and a selection line electrically connected to the first to third switches. The signal line is electrically connected to a gate of the driving transistor through the first and second switches. The memory stage is electrically connected between a gate of the driving transistor and the second terminal. The first switch is electrically connected between a drain and a gate of the driving transistor. The driving transistor has a drain electrically connected to the signal line through the second switch and further to the first terminal through the third switch.
