Description

technical field [0001] The invention relates to an image display driving method applied to a slot-type plasma display panel, especially a novel bipolar energy recovery sustain circuit is added to a sustain pulse circuit to further reduce the power of the slot-type plasma display panel during image display. consumption. Background technique [0002] The plasma flat panel display (PDP), which emerged in the early 1990s, has attracted widespread attention for its advantages of digitization, large screen, high resolution, high definition, wide viewing angle, thin thickness and light weight. [0003] At present, the existing PDP screens all use a three-electrode AC plasma flat panel display (AC-PDP). Sustain electrodes (X electrodes) and scan electrodes (Y electrodes), both of which are called display electrodes, address electrodes (A electrodes) are vertically distributed on the rear substrate, and X electrodes and Y electrodes are parallel to each other and connected to A elec...

Problems solved by technology

[0005] In the maintenance period, in order to realize the image display of the slot-type plasma display panel, a bipolar energy recovery and maintenance drive circuit is used. This circuit adopts the method of separating the positive and negative voltage energy recovery and maintenance circuits, although it can meet the requirements of SM-PDP. Display requirements, but they use two energy conversions, and the energy conversion efficiency is not very high. In order to further improve the conversion efficiency of the energy recovery and maintenance drive circuit, a new type of bipolar energy recovery and maintenance circuit is proposed, so that the whole machine Power consumption is further reduced
