Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] figure 1 It is a ramp wave driving method in the prior art, and the driving waveform is composed of a preparation period Reset, an address period Address, a sustain period Sustain and an erase period Erase. In the preparation period, the wall charge in the discharge cell obtains a consistent state; in the address period, the address voltage on the address electrode Y and the voltage on the scan electrode A are used to address the data of the image, the address electrode Y and the voltage on the scan electrode A are used to address the data of the image. An addressing discharge is generated on the scan electrode A to select the unit to emit light and the unit not to emit light, so that the unit to emit light is in the selected state and accumulates wall charges, while the unit that does not emit light is in the extinguished state and do...

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. Contents of the invention [0003] In order to solve the disadvantages of low luminous efficiency and low b...
