Embodiment Construction

[0022] In the following detailed description, only certain exemplary embodiments of the present invention are shown and described simply by way of illustration. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive. Like reference numerals refer to like elements throughout the specification.

[0023] Wall charges mentioned in the following description refer to charges formed and accumulated on a wall (eg, a dielectric layer) close to an electrode of a discharge cell. Wall charges will be described as being "formed" or "accumulated" on the electrodes, even though the wall charges do not actually contact the electrodes. Also, the wall voltage may mean a potential difference formed on the wall of the discharge cell by wall charges.

Abstract

The driving waveform is applied to the scan electrodes while the sustain electrodes are biased at the ground voltage, thereby eliminating the need for a driving board for driving the sustain electrodes. In addition, when a plurality of scan electrodes are grouped into groups and gray values ​​are expressed using a frame-subfield method, sustain discharges can be stably generated during the sustain period by reducing the time gap between the address and sustain periods. When a sustain pulse is applied during a sustain period between two adjacent address periods, the final voltage is set to a low-level voltage.

Description

technical field [0001] The present invention relates to a plasma display device and a method for driving the plasma display device. Background technique [0002] A plasma display device is a display device that displays characters or images using plasma generated by gas discharge. Depending on size, it includes as many as several hundred thousand to several million pixels arranged in a matrix. Such a plasma display panel (PDP) is classified into a direct current (DC) type and an alternating current (AC) type according to its discharge cell structure and the waveform of a driving voltage applied thereto. [0003] A DC PDP has electrodes exposed to the discharge space, so it allows direct flow through the charge space while voltage is applied. Therefore, such a DC PDP has the disadvantage of requiring a resistor for current limiting. AC PDPs, on the other hand, have electrodes covered with a dielectric layer to form a capacitor to limit current and protect the electrodes fr...
