Voltage-source thin film transistor driver for active matrix displays

A driver circuit for an active matrix display, said driver circuit comprising:

• a first transistor, said first transistor comprising a source, a drain and a gate;
• a storage capacitor, said storage capacitor comprising a terminal, said terminal connected to one line, said one line comprised of a group of said source and said drain of said first transistor;
• a second transistor, said second transistor comprising a source, a drain and gate, wherein said gate is connected to said terminal of said storage transistor;
• wherein said drain and said source of said second transistor are connected to one of group, said group comprising a power source and a pixel element respectively;
• a ballast resistor connected to said pixel element;
• and
• further wherein said storage capacitor is chargeable to sufficiently high voltage to operate said second transistor in its linear region of operation.
