Embodiment Construction

[0029] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0030]The display and addressing separation driving method proposed by the present invention is composed of a reset period, an address period, a sustain period, and an adjustment period. The driving waveform of each field is composed of a plurality of subfields, and each subfield is composed of a reset period, an address period, The maintenance period consists of the reset driving waveform voltage amplitude on the Y electrode of the first subfield is relatively high, the amplitude is VS+VSC, and the reset driving waveform amplitude of other subfields is VS. This driving method is different from the traditional ADS driving The method is the same, and the display can be turned on normally. The feature of the present invention is that the adjustment period driving waveform is added on the basis of the traditional driving method. Thi...

Abstract

The invention provides an actuating device for a plasma display, which is characterized in that: the actuating device comprises an image detection module which is used for judging whether the imaged displayed by the display is in one of a long-term static mode, a dynamic mode, and a mode from the static mode to the dynamic mode and outputting a judgment result; and a driving control module which is used for setting the actuating mode according to the judgment result output from the image detection module; by adopting the invention, the purpose of inhibiting residual images is achieved, and the adaptability of PDP display devices in various occasions can be improved.

Description

technical field [0001] The invention relates to the field of plasma display (Plasma Display Panel, PDP), in particular to a driving device and a method for driving a plasma display by adopting addressing and display separation technology. Background technique [0002] Recently, liquid crystal display technology, electroluminescent display technology, plasma display technology and other flat panel display technologies have achieved rapid development. Compared with other flat panel displays, plasma displays have the advantages of high brightness, high luminous efficiency, and simple manufacturing process. , so it is a more advantageous competitor to replace the cathode ray tube in the field of large-screen display. [0003] The plasma display uses ultraviolet rays generated by gas discharge to excite phosphors to emit light to display characters or images. According to different driving voltages and display units, plasma displays can be divided into DC discharge type and AC d...
