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

Embodiment Construction

[0066] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0067] FIG. 5 is a diagram for explaining the basic principle of the present invention. In FIG. 5 , for convenience of explanation, 10 display lines L1 to L10 are provided, and one frame is composed of 10 subframes. This configuration is not a limiting example, and the invention is equally applicable to configurations with other numbers of display lines and other numbers of subframes.

[0068] As shown in FIG. 5, a frame of 16.667 ms is divided equally to provide subframes SF1 to SF10 having an equal length (1.667 ms). Each subframe is composed of three types of driving operations, namely, reset driving operation, scan driving operation (address driving operation), and hold driving operation.

[0069] The driving operation starts from the first subframe SF1. At the start of the subframe, a reset driving operation is performed for all display lines, thereby setting th...

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 plasma display devices, circuits for driving such devices and methods for driving such devices, and more particularly to plasma display devices based on sub-frame methods, circuits for driving such devices, and methods for driving such devices 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 conventional cathode ray tubes. In the field of large-sized 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 further popularization of the product, cost reduction, improvement in display characteristics, and further improvement in function of the device are desired. Also, there is an ever-increasin...
