Abstract

A method and apparatus for driving a plasma display panel which has been improved to increase brightness and achieve high resolution. The method and device for driving a plasma display panel according to the present invention use the first video signal field to display the discharge cells of the (3i-2) and (3i-1) rows; and use the second video signal field to display the (3i- 1) and discharge cells in row (3i).

Description

technical field [0001] The present invention relates to a plasma display panel, in particular to a method and a device for driving a plasma display panel, which is improved to increase brightness and realize high resolution. Background technique [0002] Generally, a plasma display panel (PDP) emits light from phosphors using ultraviolet rays generated by discharge of an inert mixed gas such as He+Xe, Ne+Xe, or He+Ne+Xe, thereby displaying images including characters and graphics. Such a PDP can be easily formed into a large-sized film shape. Also, due to recent technological developments, the quality of images produced by PDPs has been greatly improved. In particular, since the three-electrode alternating current (AC) surface discharge PDP has wall charges accumulated on the surface by discharge and prevents sputtering of electrodes due to discharge, it has advantages of low voltage driving and long lifespan. Also, since the PDP does not have to form an activation switch ...
