CELL DRIVING DEVICE FOR USE IN FIELD EMISSION DISPLAY |
摘要 |
A cell driving device of a field emission display having a field emission pixel cell with a cathode (10) for emitting electrons and a gate electrode (12) for focusing and accelerating the electrons emitted from the cathode. The cell driving device includes: a first switching unit (14) for switching a first voltage (Vdd1) provided to the gate electrode (12); at least more than two transistors (18, 20, 22, 24) for current control, which are in parallel connected to form a current mirror between the cathode and a second voltage (Vdd2); a voltage dividing unit coupled between a third voltage (Vdd3) and the second voltage (Vdd2) to drive the at least more than two transistors (18, 20, 22, 24) for current control at the same voltage; at least more than two transistors for voltage switch each connected between the voltage dividing unit and the transistor for current control; and a controlling unit (38) for controlling at least more than two transistors (30, 32, 34, 36) for voltage switch according to the size of a video signal (VS). |
