Plasma display panel with simultaneous address drive operation and sustain drive operation

Abstract

A circuit for driving a plasma display panel which includes first electrodes, second electrodes, and third electrodes extending substantially perpendicular to the first and second electrodes includes a first driver circuit configured to drive the first electrodes, a second driver circuit configured to drive the second electrodes, a third driver circuit configured to drive the third electrodes, and a control circuit configured to control the first through third driver circuits such as to perform an address drive operation and a sustain drive operation simultaneously in parallel by performing the sustain drive operation to apply a sustain voltage between a first electrode and a second electrode adjacent to each other so as to sustain electric discharge at display cells while performing the address drive operation to successively apply a scan voltage to the first electrodes and apply an address voltage to the third electrodes so as to select the display cells.

Description

Technical field [0001] The present invention generally relates to a plasma display device, a circuit for driving such a device, and a method for driving such a device, and more particularly to a plasma display device based on a sub-frame method, a circuit for driving such a device, and driving such a device Methods. Background technique [0002] Flat display devices using flat display panels have been put into practical use in a wide range of applications from small displays to large displays, and are replacing traditional cathode ray tubes. In the field of large-size displays, plasma display panels (PDPs) are considered excellent due to advantageous features derived from operating principles and structures, and are commercialized as mainstream products. [0003] In order to promote the further popularization of the product, it is hoped that the cost of the device will be reduced, the display characteristics will be improved, and the function will be further improved. Furthermore...

AI Technical Summary

Problems solved by technology

As a result, the device becomes complicated and expensive, which is disadvantageous in terms of cost

In addition, an increase in the peak current component means an increase in the radiation of noise signals from the drive circuit, thereby increasing the possibility that the circuit control suffers from failure

There is another problem that the influence on the surrounding environment may become large due to the radiation of electromagnetic energy
