Problems solved by technology

[0017] At the same time, the existing PDP increases the imaging degree by increasing the number of lines and the number of cells, and increases the sub-field in order to reduce the contour noise. In this case, there is a problem that it is difficult to sufficiently ensure the maintenance period ( display period)
[0028] Compared with the single-scanning method with the same imaging degree, this double-scanning method reduces the addressing time by about 1 / 2, but it requires a data drive circuit 41A for driving the upper half of the data electrodes and a The data drive circuit 41B that drives the data electrodes in the lower half, therefore, it has the problem that the number of integrated circuits on which the data drive circuit is integrated increases significantly

Abstract

An addressing method of plasma display includes dividing a picture time to be multiple subfield for carrying out time division drive, providing the same data to at least two lines in subfield set with low weighted value of various fields for seeking cellular body, and applying single scanning to save addressing time of plasma display.

Description

(1) Technical field [0001] The invention relates to a plasma display addressing method and device which uses a single scan and can reduce the addressing time. (2) Background technology [0002] Plasma display (PLASMA DISPLAY PANEL: hereinafter referred to as "PDP") uses the ultraviolet light emitted by the mixture of He+Xe, Ne+Xe and He+Ne+Xe and other inert gases to make the phosphor emit light and display images. Not only can this kind of PDP be made ultra-thin and large-sized easily, but also, with the help of recent technological development, it can also greatly improve the picture quality. Recently, the development and test work of a 3-electrode AC surface discharge type PDP that lowers the driving voltage by accumulating wall charges on the dielectric is being widely carried out. [0003] Referring to Figure 1, it can be seen that the original 3-electrode AC surface discharge type PDP places n scan electrodes (Y1 to Yn) and n sustain electrodes (Z) in the discharge sp...
