Embodiment Construction

[0025] Hereinafter, specific exemplary embodiments according to the present invention will be described with reference to the accompanying drawings. When a first element is described as being connected to a second element, the first element may not only be directly connected to the second element but may also be indirectly connected to the second element through a third element. Furthermore, elements not necessary for a complete understanding of the invention have been omitted for the sake of clarity. In addition, the same reference numerals denote the same elements throughout.

[0026] figure 1 is a diagram of a plasma display panel (PDP) according to an embodiment of the present invention.

[0027] refer to figure 1 , The PDP of the present invention includes an address driver 102 , a sustain driver 104 , a scan driver 106 , a power supply 108 , a controller 110 and a display panel 112 .

[0028] The display panel 112 includes scan electrodes Y1-Yn (or first electrodes) ...

Abstract

A method of driving a plasma display panel (PDP) capable of improving gray scale display comprises the steps of applying pulses having a first voltage to first electrodes and second electrodes during a sustain period of at least one subfield and reducing a voltage of the first electrodes to a voltage of one-half of the first voltage while maintaining a voltage of the second electrode at a second voltage.

Description

[0001] This application claims priority to Korean Patent Application No. 10-2007-0116302, filed on Nov. 14, 2007 at the Korean Intellectual Property Office, entitled "METHOD OF DRIVING PLASMA DISPLAY PANEL" Right, reference is made to the Korean application, which is incorporated herein. technical field [0002] The present invention relates to a driving method of a plasma display panel (PDP), more particularly, to a driving method of a PDP capable of improving gray scale display. Background technique [0003] A plasma display panel (PDP) emits light from a phosphor using ultraviolet (UV) rays of 147 nm generated during discharge of an inert gas mixture, thereby displaying a predetermined image. Due to recent technological development, it is possible to easily manufacture thin and large PDPs, and the PDPs provide images with significantly improved picture quality. [0004] In order to realize the grayscale of an image, the PDP divides one frame into a plurality of subfields...
