Embodiment Construction

[0052] The present invention provides a plasma display panel driving circuit so that the supplementary voltage is exactly half of the sustained voltage generated. The prior art can only make the supplementary voltage fall near half of the sustained voltage generated, but the present invention can make it fall exactly half, which is the advantage of the present invention. The voltage strength of some components is therefore reduced. In addition, the number of elements in the circuit can also be reduced by using the driving circuit of the present invention.

[0053] Please refer to Figure 4 . Figure 4 It is a schematic circuit diagram of the plasma display panel driving circuit according to the first embodiment of the present invention. As shown in the figure, the driving circuit 400 includes a panel equivalent capacitor Cp of the plasma display panel, and the panel equivalent capacitor Cp includes an X terminal and a Y terminal. The driving circuit 400 includes switches S...

Abstract

A driving circuit for producing sustain waveforms of a plasma display panel (PDP) is mentioned. The driving circuit includes the functions of voltage clamping and energy recovery. By controlling switches contained in the driving circuit, the supplied voltage source can be made to be only half of the sustain voltage. The voltage stress of some components will therefore be lower. In addition, the numbers of components can be reduced in the driving circuit.

Description

technical field [0001] The invention provides a driving circuit of a plasma display panel, especially a driving circuit of a plasma display panel which uses a switch to generate a continuous voltage. Background technique [0002] In recent years, the demand for flat panel displays has gradually grown, such as plasma display panels (plasma display panels, PDPs), liquid-crystal displays (liquid-crystal displays, LCDs) and electroluminescent displays (EL displays). And because these displays have the advantages of lightness and thinness, they have gradually replaced cathode ray tube displays (CRT). [0003] In the plasma display panel, the electric charge needs a continuous discharge pulse to be applied to the electrode to generate the discharge beam, and realize the purpose of display according to the display information. As far as the plasma display panel is concerned, a high voltage must be applied to the electrodes, especially a pulse that can last several microseconds (mi...
