Embodiment Construction

[0025] Certain embodiments are described more fully hereinafter with reference to the accompanying drawings.

[0026] figure 1 is a perspective view of a 3-D surface discharge type PDP 1 described according to an embodiment.

[0027] refer to figure 1 , The 3-D surface discharge type PDP1 includes: a first glass substrate 10 and a second glass substrate 13 . Addressing electrode A R1 ..., A Rm , the first and second dielectric layers 11 and 15, the Y electrode Y 1 ,...,Y n , X electrode X 1 ,...,X n , a phosphor layer 16 , a fence bar 17 and a protective layer 12 (such as a magnesium oxide (MgO) layer) are all disposed between the first glass substrate 10 and the second glass substrate 13 .

[0028] Address electrode AR 1 ,..., AR m formed on the second glass substrate 13 in a predetermined pattern. The bottom dielectric layer 15 is formed to substantially cover the address electrodes A R1 ,...,A Rm . Barrier bars 17 are formed on the bottom insulating layer 15...

Abstract

An apparatus for driving a display panel that applies a power source having at least one level to each of a plurality of electrodes is disclosed. The electrodes are divided into at least two groups and so as to reduce the instantaneous change in current when the electrodes are driven, the at least two groups are not driven at the same time.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2005-0126894 filed with the Korean Intellectual Property Office on December 21, 2005, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a device and a method for driving a display screen, in particular to a device and a method for driving a display screen by using high-voltage, high-frequency electric energy to display images through repeated discharge in a short period of time. Background technique [0004] A plasma display panel (PDP) can be easily manufactured in a large size, and thus is widely used as a flat panel display. PDPs display images using a discharge phenomenon, and generally, PDPs are classified into DC PDPs and AC PDPs according to the type of their driving signals. Due to the inconvenience of long discharge delays in DC PDPs, AC PDPs have been more active...
