Embodiment Construction

[0094] Below, refer to the attached Figure 7 The implementation of the plasma display driving method and device of the present invention will be described in detail with FIG. 10 .

[0095] The plasma display driving method and device according to the embodiments of the present invention are fully applicable to the selective writing (SW) mode, the selective erasing (SE) mode, and the above-mentioned selective writing (SW) mode and selective erasing (SE) mode. The Selective Write Erase (SWSE) method combined with the method.

[0096] Figure 7 It is a screen structure and a waveform diagram for explaining the driving method of the plasma display according to the first embodiment of the present invention.

[0097] refer to Figure 7 It can be seen that, for the driving method of the plasma display, the gray value represented in the sustain period is determined by the number of discharges performed in the sustain period. In order to cause this discharge, during the sustain pe...

Abstract

The invention discloses plasma display screen activation method and device, which comprises the following parts: scanning electrode, maintaining electrode and addressing electrode. The method comprises the following steps: dividing one frame time into several subplaces; generating the maintaining impulse of at least two working quantity numeral in the maintaining period.

Description

(1) Technical field [0001] The present invention relates to the technology of the plasma display, in particular to the driving method and device of the plasma display capable of increasing the display quality. (2) Background technology [0002] Recently, a flat display device capable of significantly reducing the weight and volume of a cathode ray tube has attracted more and more attention. Such flat panel display devices include liquid crystal display devices (Liquid Crystal Display: LCD), plasma displays (Plasma Display Panel: PDP), field emission display devices (Field Emission Display: FED), electroluminescent devices (Electro-Luminesence: EL), etc. , these devices provide us with display devices that can display digital signals or analog data. [0003] The plasma display uses the 147nm ultraviolet rays emitted by the mixture of inert gases such as He+Xe, Ne+Xe and He+Ne+Xe to make the phosphor emit light, and display the screen including text, pictures and moving image...
