The operation principle of the colored alternating current-direct current hybrid plasma of the utility model four electrode surface discharge types display is described with the course of work of single discharge cell 5 and characteristic below.Shown in Fig. 5,6, be the drive waveforms and the wall change in charge figure of the colored alternating current-direct current hybrid plasma of four electrode surface discharge types display.The utility model keeps electrode A electrode 10 and 11 at B electrode applies the high-voltage alternating pulse, and addressing electrode D electrode 13 and 12 at scan electrode C electrode apply the low-voltage direct pulse, so the utility model belongs to the hybrid plasma volumetric display.
In the present embodiment, plasma scope firing voltage Vf=300V of the present utility model keeps voltage Vs=160V, addressing pulse Vb=30V, prefiring pulse Vp=285V, erasing pulse Ve=200V.The utility model belongs to the condenser type electrical appliance, and discharge cell 5 total capacitances equal dielectric capacitance series connection gas electric capacity; Because the dielectric capacitance dividing potential drop has only several volts.So the gas voltage Vg of gas electric capacity approximates external electric field voltage.As gas voltage peak among Fig. 5 all is because the dielectric capacitance branch has gone sub-fraction voltage to cause for value approximately.Owing to keep voltage Vs amplitude, so apply between total electrode (A electrode 10 and B electrode 11) that to keep pulse be the Discharge illuminating of can not lighting a fire keeping less than firing voltage Vf.In address period, before being t0 to t1: apply prefiring pulse Vp between electrode keeping, because the Vp amplitude is lower than firing voltage Vf, depending merely on prefiring pulse Vp is to make discharge cell 5 discharges, must apply addressing pulse Vb to addressing electrode D electrode 13 and 12 at scan electrode C electrode again.Because A electrode 10 is overlapping with C electrode 12, B electrode 11 is overlapping with D electrode electrode slice 131, and 11 at A electrode 10 and B electrode are an electric charge system, and 13 at C electrode 12 and D electrode are another electric charge system, just as subtend discharge-type chromatic alternating-current plasma display, electrode and wall electric charge are overlapping, thereby formation superposition of electric field, so prefiring pulse Vp and addressing pulse Vb play superposition in the same way, superimposed voltage approximates 310V (285V+30V ≈ 310V) and surpasses firing voltage Vf and Discharge illuminating, and at magnesium oxide rete 4 surface accumulation wall electric charges.The wall voltage Vw that produces approximates 310V, finishes addressing and shows.The phase of keeping (before being t1 to tn), applying and keep pulse Vs alternating voltage keeping 11 at total electrode A electrode 10 and B electrode.13 voltages of C electrode 12 and D electrode are 0V during this period.Keep pulse Vs during t1 and wall voltage Vw superposes in the same way, (310V-160V ≈-465V), its absolute value voltage surpasses firing voltage Vf and Discharge illuminating to its amplitude pact-465V.Wall voltage Vw during t2 is about 158V, approximates to keep pulse Vs.T2 constantly applies and keeps pulse Vs keeping total electrode again, and Vw superposes in the same way with wall voltage, and its voltage magnitude is about 315V (158V+160V ≈ 315V) and surpasses firing voltage Vf and Discharge illuminating.After this each is kept pulse Vs and all superposes in the same way with wall voltage Vw before the tn, and the voltage magnitude absolute value all approximates 315V, all surpasses firing voltage Vf and Discharge illuminating, finishes and keeping the discharge demonstration.T0 is withholding period constantly, applies erasing pulse Ve to keeping total electrode, and Vw superposes in the same way with wall voltage, and superimposed voltage is about 355V (160V+200V ≈ 355V) and surpasses firing voltage Vf and Discharge illuminating.Because a little less than this discharge, the wall electric charge that neutralized is substantially kept also no longer igniting discharge of pulse Vs even if continue to apply, discharge process has just stopped.By foregoing as seen, discharge is caused by superimposed voltage that all gas voltage equals superimposed voltage each time.Superimposed voltage is that external electric field voltage deducts dielectric capacitance dividing potential drop (a few volt) voltage afterwards.
The utility model plasma scope technology to full frame drive principle is: address discharge shows the phase, before this full frame total electrode (A electrode 10 and B electrode 11) of keeping was applied a prefiring pulse Vp charging, the C electrode 12 of lining by line scan then, be switched on or switched off each root D electrode 13 by displaying contents, C electrode 12 and the D electrode of connecting 13 applied addressing pulse Vb, make the discharge that superposes in the same way of prefiring pulse Vp and addressing pulse Vb voltage finish the addressing demonstration.Keep the discharge demonstration phase, only keep pulse Vs and the wall voltage Vw igniting Discharge illuminating (continuously) that superposes in the same way of keeping that applies interchange between total electrode and finish and keeping the demonstration of discharging two.In the phase of keeping, the discharge cell 5 that has only addressing to choose is kept Discharge illuminating.In withholding period, apply superpose in the same way discharge and wipe the wall electric charge and stop discharge process of an erasing pulse Ve and wall voltage Vw to keeping total electrode.
In drive scheme of the present utility model, address period, 13 at C electrode 12 and D electrode apply the low pressure addressing pulse Vb that is lower than 45V, the voltage on this two arrays of electrodes is 0V when discharging demonstration phase and withholding period and keep, so with this two arrays of electrodes supporting need be the low pressure IC of the withstand voltage 45V of being lower than only, greatly reduced cost; Because existing IC technology is withstand voltage about 200V, by existing IC technology, have only the withstand voltage 45V of being lower than just to be easy to make IC, withstand voltage low more IC is cheap more.Keep 11 at electrode A electrode 10 and B electrode and be arranged in parallel, run through every discharging electric unit 5, keeping the discharge demonstration phase, apply alternating current and keep pulse Vs and then can finish and keeping discharge and show keeping electrode; Then apply erasing pulse Ve in the phase of stopping doing business, just can make discharge cell 5 stop discharge keeping electrode.Though it is higher to keep the voltage magnitude of pulse Vs and erasing pulse Ve, it is a total electrode that but the A electrode 10 of keeping electrode can converge, it is a total electrode that B electrode 11 also can converge, so only need connecting the high voltage transistor of an output AC, this two arrays of electrodes gets final product, compared with prior art, the number of high voltage transistor significantly reduces, and has reduced cost.In sum, the utility model has not only improved brightness but also greatly reduce cost.Certainly, the above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
