Abstract

A driving device of a flat display panel and its method are disclosed. The driving device includes a scan driving unit for applying scan pulses o both ends of each scan line of the flat display panel.

Claims

1. A driving device of a flat display panel comprising:

a scan driving unit for applying scan pulses to both ends of each scan line of a flat display panel.

2. The device of claim 1, further comprising a controller for outputting a control signal for controlling the scan driving unit.

3. The device of claim 2, wherein the controller outputs a control signal for simultaneously applying the scan pulses.

4. The device of claim 1, wherein the scan pulses have the same voltage, phase and pulse width.

5. A driving device of a flat display panel comprising:

a first scan driving unit for applying scan pulses to one side of each scan line of a flat display panel; and

a second scan driving unit for applying the scan pulses to the other side of each scan line.

6. The device of claim 5, further comprising a controller for outputting a control signal to control the scan driving unit.

7. The device of claim 6, wherein the controller outputs a control signal to simultaneously apply the scan pulses.

8. The device of claim 5, wherein the scan pulses have the same voltage, phase and pulse width.

9. The device of claim 6, further comprising a data driver for applying data pulses to data lines of the flat display panel.

10. The device of claim 9, wherein the data driving unit comprises:

a first data driving unit for applying data pulses to the odd number of times of data lines among data electrodes; and

a second data driving unit for applying data pulses to the even number of times of data lines of the data electrodes.

11. A driving method of a flat display panel comprising:

applying scan pulses to both ends of each scan line of a flat display panel.

12. The method of claim 11, further comprising outputting a control signal to simultaneously apply the scan pulses.

13. The method of claim 11, wherein the scan pulses have the same voltage, phase and pulse width.
