Description
The present invention relates to a kind of plasma display (plasma display parel, PDP) driving method and device, being particularly related to can be for plasma display, background flicker (backglow) phenomenon that discharge (discharge) operation is caused in (resetperiod) during reducing it and resetting.
PDP utilizes the mode of electrode discharge stored charge to show, owing to have big video screen, high power capacity and can show full color (full-color) image, is the flat-panel screens of following tool potentiality.Below be illustrated with regard to ultimate principle and the mode of operation of PDP.
Fig. 1 represents the side cutaway view of unit among the known technology PDP (cell) structure.As shown in the figure, PDP mainly by two glass substrates 1 and 7 and upper member formed, then insert inert gas in the cavity between glass substrate 1 and 7 (cavity), as Ne, Xe.On glass substrate 1, comprise and keep electrode (sustain electrodes) X and scan electrode Yi (extending parallel to each other), dielectric layer 3 and diaphragm (protective film) 5.Then comprising address electrode (address electrodes) Ai and the fluorescent material 9 on it on the glass substrate 7.Around each unit, then isolated with dividing wall (partition wall) 8.Therefore, comprising three electrodes in each unit 10, is respectively parallel to keep electrode X and scan electrode Yi and across the address electrode Ai on it.
Fig. 2 represents to utilize the calcspar of the electrode display that PDP formed shown in Figure 1.As shown in the figure, PDP100 is by scan electrode Y1～Yn parallel to each other and keeps electrode X, and drives across the Al of the address electrode on it～Am.The position of unit 10 is isolated by the dividing wall shown in Fig. 18 then as shown in FIG..In addition, plasma scope also comprises control circuit (control circuit) 110, Y scanner driver (Y scan driver) 112, keeps driver (X driver) 114 and address driver (address driver) 116.Control circuit 110 produces the needed time sequence information of each driver according to clock pulse signal CLOCK, data-signal DATA, vertical synchronizing signal VSYNC and horizontal-drive signal HSYNC that the outside provided.Wherein clock pulse signal CLOCK represents the data transfer clock pulse, data-signal DATA represents video data, and vertical synchronizing signal VSYNC and horizontal-drive signal HSYNC then are in order to define the sequential of single frame (frame) and single scanning line (scanning line).Control circuit 110 is delivered to address driver 116 with video data and time clock, and relevant frame control timing is delivered to Y scanner driver 112 and kept driver 114.Must be noted that to show that related data is to deliver to address driver 116 by control circuit 110, and when Y scanner driver 112 scans each scan electrode Y1～Yn in regular turn, video data is write in each unit by address electrode A1～Am.Its detailed display action and the needed control signal of each electrode then are described as follows in conjunction with Fig. 3 and Fig. 4.
Fig. 3 represents that known technology drives the action synoptic diagram that PDP shows a frame (frame).As shown in the figure, each frame is divided into 8 son (sub-field) SF1～SF8.Should be noted that, the meaning of this virgin field and conventional cathode ray tube (cathode ray tube, CRT) field in (field) difference, field among the traditional C RT is to scan demonstration for the odevity sweep trace respectively, and the field of PDP then is to show different greyscale level (gray scale) for whole sweep traces.Each son is by forming during three operational motions, be respectively (reset period) R1～R8 during the replacement, write during (address period) A1～A8 and keep during (sustain period) S1～S8.During the replacement be when being used for removing last son and showing remaining electric charge, and the wall electric charge (wall charge) that in each unit, stays some.Then be by address discharge (address discharge) (promptly being the on state) accumulation wall electric charge in the unit that needs show during writing.Then be to accumulate in the unit of wall electric charge by the address discharge, showing during keeping to keep discharge (sustain discharge).Wherein, during the replacement R1～R8 and keep during S1～S8 be whole unit of handling simultaneously on the PDP, A1～A8 carries out write activity for each unit on each scan electrode Y1～Yn in regular turn during writing.In addition, display brightness be with keep during the length of S1～S8 be directly proportional.In the example of Fig. 3, the length of S1～S8 can be made as 1: 2: 4 during keeping among each son SF1～SF8: 8: 16: 32: 64: 128 ratio, realize 256 GTGs thus.
Fig. 4 represents known technology sequential chart of control signal on each electrode in single son.Wherein the signal on the address electrode Ai is produced by address driver 116, and the signal of keeping on the electrode X is produced by keeping driver 114, and the signal on scan electrode Y1～Yn is produced by scanner driver 112.As shown in the figure, each son be comprise replacement during, write during and keep during.Below describe in detail signal waveform during each with and the action that caused.
Time point a during resetting, scan electrode Y1～Yn is made as 0V, keep then send on the electrode X magnitude of voltage be VS+VW write pulse (write pulse) 201, wherein magnitude of voltage VS+VW is greater than the discharge start voltage of keeping between electrode X and the Yi (discharge start voltage).Therefore, occur universe between electrode X and the scan electrode Yi and write discharge (total write discharge) W keeping.This discharge process can be accumulated negative charge keeping on the electrode X, has accumulated carbonium on scan electrode Yi.Since the accumulation the electric field that negative charge and carbonium caused can balance out the pressure reduction of keeping between the electrode, so universe write the discharge W time very short.
Then at time point b, keep electrode X and be made as 0V, that then sends into magnitude of voltage on all scan electrode Y1～Yn and be VS keeps pulse (sustain pulse) 202, wherein magnitude of voltage VS add accumulate on keep the magnitude of voltage that electric charge caused between electrode must be greater than the discharge start voltage between scan electrode Yi and the X.Therefore occur universe between electrode X and the scan electrode Yi and keep discharge (total sustaindischarge) S keeping.This discharge process is opposite with last discharge process, keeping meeting accumulation carbonium on the electrode X, can accumulate negative charge on scan electrode Yi.
Then at time point c, scan electrode Yi is made as 0V, keeps the reset pulse (erase pulse) 203 of then sending into magnitude of voltage on the electrode X and being lower than VS, also can send on address electrode Ai simultaneously-address pulse of VS.Reset pulse 203 is to be used for neutralization (neutralize) Partial charge, stays needed wall electric charge at last on scan electrode Y1～Yn.During this wall electric charge makes during follow-up the writing, can carry out write activity with lower magnitude of voltage.
During then beginning to write.At first at time point d, will keep electrode X and scan electrode Yi is pulled to magnitude of voltage VS.Then, send into scanning impulse (scan pulse) 204 for each scan electrode Y1～Yn in regular turn, on address electrode Ai, send into the address pulse that magnitude of voltage is VA simultaneously from time point e.When the unit in certain sweep trace is when being made as ON, then can write discharge, just the video data with correspondence writes in this element.
After the scanning of finishing all scan electrode Y1～Yn, then enter keep during.At first electrode X will be kept respectively and scan electrode Yi is made as 0V.Then in staggered mode (time point f and time point g), keep pulse 205 to what keep that electrode X and scan electrode Yi send into identical magnitude of voltage.The unit that is written into the on data this moment during writing promptly can display brightness.Mandatory declaration be, above-mentioned illustrated drive signal waveform is an example only, the waveform in practical application is an example difference therewith, but ultimate principle is consistent.
As previously mentioned, the length during keeping is directly proportional with the brightness of its demonstration.Suppose to comprise in the frame 510 times and keep discharge cycle (phase comprises twice discharge weekly), then in son SF1～SF8, keep discharge cycle quantity and can be configured to 2,4,8,16,32,64,128,256 respectively.Therefore, the discharge time during being used to keep during a frame shows is 510 * 2=1020.The discharge operation of this part is the major part of display image.
On the other hand, in fact also carried out 2 to 3 discharge cycles during resetting, for example universe writes discharge, universe is kept discharge and removed discharge, so that even distribution wall electric charge.But, interior discharging action also can produce brightness during these were reset, simultaneously can be a little more than brightness that discharging action produces during keeping.The brightness rough, that five discharges were produced during the brightness that inferior discharge of the period three of resetting is produced approximated greatly and keeps.Therefore the ratio of high-high brightness and minimum brightness is approximately 1020: 5 * 82=26 on PDP: 1, and it is corresponding to the brightness of black (black).Therefore, the brightness that discharge is produced during resetting is lower better, so can improve the black image quality.The black image quality is one of important parameter of image demonstration, therefore reduces the luminance effect that discharging action caused during resetting and is the necessary important topic that solves.
In view of this, fundamental purpose of the present invention is to provide a kind of driving method of plasma display panel and device, particularly solves the problem that the discharge operation during resetting in each son field influences for brightness of image.
According to above-mentioned purpose, the present invention proposes a kind of driving method of plasma display panel, comprises many electrode and the scan electrodes kept parallel to each other on the plasma display, and across many address electrodes keeping electrode and above-mentioned scan electrode.Wherein, on the very first time point during resetting, send into a universe and write pulse to keeping between electrode and the scan electrode, in order to by keeping the wall electric charge that discharging action between electrode and the scan electrode produces each unit in the plasma display, it is to rise to second voltage with big slope waveform by first voltage that universe writes pulse, rise to a tertiary voltage with less slope waveform from second voltage again, this less slope waveform can be a variable Rate cumulative or decrescence.In addition, universe writes pulse also can utilize less slope waveform, rises to second voltage by first voltage, utilizes big slope waveform again, rises to tertiary voltage by second voltage.Part with big slope waveform booster tension can be accumulated the wall electric charge in a large number, then can avoid causing strong brightness with the part of less slope waveform booster tension, influences display quality.
In addition, the present invention proposes a kind of plasma display panel driving device, and it comprises: control circuit, in order to receive outside video data and correlation timing data thereof; Address driver is coupled to control circuit, in order to drive address electrode; The X driver, be coupled to control circuit, keep electrode in order to driving, wherein during resetting, send into universe and write pulse to keeping electrode, in order to by keeping the wall electric charge that discharging action between electrode and the scan electrode produces each unit in the above-mentioned plasma display.It is to rise to second voltage with big slope waveform by first voltage that this universe writes pulse, rise to tertiary voltage with less slope waveform from second voltage again, or rise to second voltage by first voltage with less slope waveform, rise to tertiary voltage with big slope waveform by second voltage again; And the Y scanner driver, be coupled to control circuit, in order to drive above-mentioned scan electrode.
In addition, the present invention proposes a kind of plasma display panel driving device, and its difference is in X driver and Y scanner driver.The X driver is sent into the first composition pulse that universe writes pulse to the above-mentioned electrode of keeping during resetting, the first composition pulse that above-mentioned universe writes pulse is to rise to second voltage with big slope waveform by first voltage.The Y scanner driver is then sent into universe and is write the second composition pulse of pulse to scan electrode during resetting, it drops to second voltage with a less slope waveform, the universe of keeping thus between electrode and the scan electrode writes the discharging action that pulse causes, and produces the wall electric charge of each unit in the plasma display.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent, a preferred embodiment cited below particularly, and in conjunction with the accompanying drawings, be described in detail below:

Fig. 8 represents in the third embodiment of the invention that each electrode (comprise address electrode Ai, keep electrode X and scan electrode Yi) is gone up the sequential chart of control signal during the replacement of son.
Now the present invention is described in detail in conjunction with the accompanying drawings.
The present invention impacts for display quality at discharge operation during resetting in the known technology, proposition can improve the driving method and the device of this problem, particularly write discharge operation that pulse causes at middle universe during resetting, increase the ability of its accumulation wall electric charge, also reduce the brightness that is produced in its discharge process simultaneously.
Fig. 5 represents in the present embodiment that each electrode (comprise address electrode Ai, keep electrode Xi and scan electrode Yi) is gone up the sequential chart of control signal during the replacement of son.Be the unit of handling simultaneously on all sweep traces during the replacement, make its wall electric charge that produces some, therefore following alleged scan electrode Yi is meant whole scan electrode Y.Generally speaking, before last son finishes, can send into a reset pulse, be used for removing the wall electric charge in the unit that in last son state is made as at scan electrode Yi.Then as shown in Figure 5, the very first time during the replacement of book field, keep and send into a universe on the electrode X and write pulse 300, allow and keep pressure reduction between electrode X and the scan electrode Yi greater than between the two discharge start voltage, by the needed wall electric charge of discharge generation.It is different with known technology that this universe writes pulse 300, and its waveform is made up of two parts.As shown in the figure, it is to be promoted to second voltage with big slope waveform by first voltage (0V) that universe writes pulse 300, is promoted to tertiary voltage with less slope waveform gradually by second voltage again.In the present embodiment, second voltage can be made as 180V, and tertiary voltage can be made as 360V.Then shown in preceding case, on scan electrode Yi, send into reset pulse 301 in regular turn, send into reset pulse 302 again.Then, then enter during follow-up the writing and during keeping.Mandatory declaration be, during resetting among Fig. 5 in the pulse configuration of each electrode control signal be not in order to limit the present invention, for knowing PDP associated drives operator, can do modification in various degree according to its displaying principle.
Because the present embodiment principal character is that universe writes pulse 300, therefore following its waveform that describes in detail.The first that universe writes pulse 300 is that (0V) is promoted to second voltage by first voltage according to big slope waveform, its role is to accumulate a large amount of wall electric charges, and this is the fundamental purpose of pulse for this reason also.Universe writes the second portion of pulse 300 then according to a less slope waveform, be promoted to tertiary voltage from second voltage, its effect also is accumulation wall electric charge, but because its voltage rate of rise is less, therefore discharge effect is not obvious than known technology, so be unlikely too bright.Generally speaking, utilize this universe to write the waveform of pulse 300, still can accumulate a large amount of wall electric charges on the one hand, but also can not cause too light ground flicker.
Fig. 6 represents the calcspar of the drive unit of present embodiment ionic medium body display panel, and its basic structure and known technology are roughly the same.Drive unit comprises control circuit 110, address driver 116, keeps driver 124 and scanner driver 122.Outside video data DATA and the transfer clock pulse CLOCK that is provided is provided control circuit 110, and time series datas such as vertical synchronizing signal VSYNC and horizontal-drive signal HSYNC, and it is delivered on each driver.116 of address drivers write video data in the unit of each sweep trace writing drive address electrode Ai.122 responsible driven sweep electrode Yi of scanner driver; Keep 124 responsible drivings of driver and keep electrode X.
As shown in Figure 5, keep driver 124 universe of being sent into during replacement of each son and write pulse, be earlier to rise to second voltage (0V-＞180V) from first voltage with big slope waveform, rise to tertiary voltage (180V-＞360V) with less slope waveform from second voltage again, utilize the discharging action of keeping in each unit between electrode X and the scan electrode Yi, produce the wall electric charge in each unit.
In addition, writing the less slope waveform of pulse 300 in the universe shown in Fig. 5, is slowly to rise with relatively large slope earlier, slowly rises with less relatively slope again, and its waveform presents the shape (to evagination) of similar quafric curve.Keep the mode that driver 124 produces this kind waveform, can utilize step voltage to synthesize and approach this waveform.
According to the above, the PDP driving method of present embodiment mainly is that the universe that is modified in during the replacement writes pulse, makes it can accumulate a large amount of wall electric charges, can not cause excessive brightness when discharge simultaneously and influences image quality.Realize that above-mentioned universe writes the waveform of pulse, then only need to revise the partial circuit of original X driver, make it can produce needed waveform, the therefore extra cost that increases is not high.
Another embodiment of the present invention is identical with basic driver mode and the drive unit of first embodiment, and difference only is that universe writes the waveform of pulse 300.In first embodiment, the first that universe writes pulse 300 rises to second voltage with big slope waveform by first voltage, second portion then rises to tertiary voltage with less slope waveform, and the voltage rate of rise then is the form that is decrescence in the second portion.Then its variability is described in the present embodiment, all can reaches purpose of the present invention with several different waveforms.
Fig. 7 a represents that universe in the present embodiment writes first kind of variation waveform of pulse 300.Shown in Fig. 7 a, universe writes waveform 300 and also rises to first voltage with big slope waveform by first voltage in first, rise to second voltage at second portion with less slope waveform, itself and the first embodiment difference are: the voltage rate of rise is the form that is cumulative in the second portion, so its waveform presents the shape that quafric curve concaves.The universe of this waveform writes pulse 300 equally can on the one hand a large amount of stored charges, avoid on the other hand sending strong brightness in discharge process and influence image quality.
Fig. 7 b represents that universe in the present embodiment writes second kind of variation waveform of pulse 300.Different with first embodiment is, the universe of Fig. 7 b writes waveform 300 and is still differentiation first and second portion, but rise with less slope waveform earlier, rise (almost vertical pulse) with big slope waveform again, so its waveform presents the shape that quafric curve concaves.The universe of this waveform writes pulse 300 equally can on the one hand a large amount of stored charges, avoid on the other hand sending strong brightness in discharge process and influence image quality.
According to the above, the present invention is not particularly limited the actual waveform that universe writes pulse, as long as and meet in two stage at least mode and come booster tension, promptly can spirit according to the invention.
The third embodiment of the present invention is that the idea with equivalent waveform realizes first embodiment.With reference to Fig. 5 of first embodiment, write pulse 300 and synthesize keeping universe on the electrode X with two parts, so the circuit of keeping driver 124 these waveforms of generation more complicated comparatively speaking, cost is also than higher.Then this universe is write two parts of pulse 300 in the present embodiment, by keeping driver 124 and scanner driver 122 generations and sending into and keep on electrode X and the scan electrode Yi, simplify Waveform generating circuit respectively with this.
Fig. 8 represents in the present embodiment during the replacement of son, address electrode Ai, keeps the sequential chart that electrode X and scan electrode Yi go up control signal.As shown in the figure, it is that in addition equivalence is synthetic to keep the first composition pulse 300a (first voltage rises to second voltage rapidly) on the electrode X and the second composition pulse 300b (tertiary voltage slowly drops to the 4th voltage) on the scan electrode Yi that universe originally writes pulse 300, and the discharge effect of its generation is identical with first embodiment.Wherein the first composition pulse 300a equals the big slope waveform component that former universe writes pulse 300, and the second composition pulse 300b equals the less slope waveform component that former universe writes pulse 300.But angle with the circuit real work, the waveform that produces Fig. 8 comes easily than the waveform that produces Fig. 5, not only keep driver 124 and do not need to use voltage-multiplying circuit, only need on scanner driver 122, increase the purpose that several primary elements can reach waveform generation simultaneously, have higher industrial utilization.
Though the present invention discloses as above with preferred embodiment; right its is not in order to qualification the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention should be as the criterion with the scope that claims were defined.
