Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] In the driving method adopted in the present invention, the preparation period and the addressing period of each subfield are divided into the first preparation period and the second preparation period, the first addressing period and the second addressing period respectively, and first enter the first preparation period period, used to provide initialization wall charges, so that the wall charges are in a unified state, that is, to provide particle effects for the upper half of the screen. At the end of the first preparation period, the control voltage drops to negative Vsc1 to 70V, and enters the first addressing period Row addressing, when the middle row is addressed, the second preparation period starts to provide additional particle effects for the lower half of the screen. At the end of the second preparation period, the control v...

Abstract

The invention discloses a double addressing periods driving method for improving addressing speed which comprises: dividing preparing period and addressing period of each subfield into first and second preparing period, first and second addressing period; entering the first preparing period first and entering the first addressing period for addressing line by line; when addressing to the middle line, starting the second preparing period and then entering the second addressing period for addressing line by line until entire display screen being addressed; entering maintaining period after addressing to maintain irradiation.

Description

technical field [0001] The invention belongs to the technical field of gas discharge and relates to a driving method for increasing addressing speed, which is especially suitable for all VGA type plasma driving circuits, especially XGA type plasma driving circuits with high XE gas content. Background technique [0002] Plasma display has the advantages of large size, wide viewing angle and simple structure, but it also has disadvantages such as low luminous efficiency and low brightness. One reason for these disadvantages is the long addressing time. Because the plasma display AC-PDP realizes the gray level through the subfield method, and each subfield has a preparation period, an addressing period and a display period, for a high-resolution plasma display, the addressing period The time is necessarily long, resulting in low luminous efficiency and low brightness. [0003] FIG. 1 is a ramp wave driving method in the prior art. The driving waveform is composed of a prepara...
