Embodiment Construction

[0044] Preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] image 3 It is a block diagram showing the configuration of the multi-scan device for the plasma display panel of the present invention. According to this figure, the multi-scanning device of the plasma display panel of the present invention has: a data signal storage unit 200, a data signal drive unit 210, a data signal comparison unit 220, a same data signal line position storage unit 230, a scanning row selection unit 240, a control part 250, a scanning signal driving part 260, and a plasma display panel 270.

[0046] Data signal storage unit 200 is input with data signals of images corresponding to each row in the row direction of plasma display panel 270 and sequentially stores them. When storing an input data signal, the data signal storage unit 200 stores a data signal corresponding to one frame (Frame). That is, the da...

Abstract

In a multi-scan device and method for a plasma display panel, data signals relative to each line of a frame are compared. Where two or more lines are found to be identical, only one copy of the line data is stored, together with data identifying the identical lines. Data signals having the same line data are then simultaneously scanned using the stored line data. By simultaneously scanning those lines having the same data signals, the panel scanning time is decreased. This allows the sustain time for generating light to be increased, thereby allowing a brighter image to be displayed.

Description

technical field [0001] The invention relates to a multi-scan device and method for a plasma display panel. Background technique [0002] Recently, increasing the quality of image display devices has attracted much attention. Especially with the increasing attention to FPD (Flat Panel Display, flat panel display), LCD (Liquid Crystal Display, liquid crystal display), OLED (Organic Light Emitting Diodes, organic light emitting diodes) replacing CRT (Cathode Ray Tube, cathode ray tube) Diode), PDP (Plasma Display Panel, plasma display panel), FED (Field Emission Display, field emission display) and other new-generation image display devices are increasing. [0003] The weight of the plasma display panel as a kind of FPD is about 1 / 6 of that of CRT, and the viewing angle is 160° or more, which is better than that of LCD. Moreover, the picture uniformity of the plasma display panel is good, and it is not affected by the earth's magnetic field, that is, the earth's magnetic fiel...
