Abstract
A driving circuit and method for driving a plasma display cell array using the circuit is disclosed. The driving circuit comprises a first transistor configured to drive the cells, a first driving sub-circuit configured to turn the first transistor on, and a second driving sub-circuit configured to turn the first transistor off when the voltage driven to the cells reaches a selected value.
Claims20
A plasma display device comprising:
- an electrode;
- a first transistor connected between the electrode and a power source configured to supply a first voltage;
- a first driver configured to change a voltage of the electrode by controlling a state of the first transistor;
- a second driver configured to cut off a path between the electrode and the power source when the voltage at the electrode is a second voltage during a first period, the second voltage being different from the first voltage, wherein the voltage of the electrode is substantially sustained at the level of the second voltage;
- and
- a second transistor connected between the electrode and the power source and configured to be turned on during a second period, the second period following the first period, wherein the first voltage is applied to the electrode when the second transistor is turned on.
