Problems solved by technology

[0017] According to this method, although the brightness of the image can be changed to about 78.8%, since the light-emitting period of some subframes is relatively shortened, and all pixels corresponding to a given scan electrode are in the "off" state, therefore It will not be possible to exceed 78.8% efficiency for displaying image frames

Embodiment Construction

[0036] Next, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0037] refer to figure 1 , which is a schematic structural diagram of an AC-type PDP driving device for gray scale display according to the present invention. figure 1 In each pixel 5, each pixel 5 includes: a first display electrode 6 and a second display electrode 7 placed parallel to each other; a scan electrode 8 located close to the second display electrode 7; 7 and scan electrodes 8 intersect with data electrodes 9 perpendicular to each other. The first and second display electrodes 6 and 7 and the scan electrodes 8 are formed under the upper glass plate 10 and covered with an insulating film 11 . The data electrode 9 is placed between the spacers 13 on the lower glass plate 12, and is perpendicular to the first and second display electrodes 6 and 7 placed on the upper glass plate 10, while being covered with red (R), green Three fluores...

Abstract

The present invention provides a gray level display AC-type PDP driving method comprising (a) driving a single image frame into n number of subframes, each of the subframes having predetermined number of substaining pulses; (b) selecting scan electrodes whose number is identical to the number of said subframes, assigning specific subframes to said selected scan electrodes, sequentially providing scanning pulses having different phases on said selected scan electrodes and applying addressing pulses on said data electrodes in order to designate pixels to be displayed, and alternately supplying the predetermined number of sustaining pulses onto the selected scan electrodes and said data electrodes, to thereby display said assigned subframes for said selected display lines; (c) shifting by one or more than scan electrode (s) from each of said selected scan electrodes; and (d) repeating said divided subframes is displayed for all the display lines, to thereby display an image frame. According to the present invention, it is possible to eliminate a suspending time and to provide advantages of advanced driving stability, high luminance and improved contrast.

Description

technical field [0001] The present invention relates generally to plasma technology, and in particular to methods for driving AC-type plasma display panels to enable them to display gray scale in display systems of the type such as TV plasma video components employing AC-type plasma display panels. methods and devices. Background technique [0002] A plasma display panel (hereinafter abbreviated as "PDP") is a device for displaying text or images using light emitted from plasma generated by gas discharge. PDPs can be classified into two types, DC type and AC type, according to a driving method of an electric field applied thereto to generate plasma. [0003] Compared with other types of flat-panel display devices, PDP has excellent characteristics such as a large screen that can be larger than 40 inches, can display full-color images, and has a wide viewing angle, making it the next-generation wall-mounted HDTV and both TV and personal. Applications in fields such as compu...
