Description

516013 V. Description of the invention α) The present invention relates to a driving method and device for a plasma display panel (PDP), in particular, it can reduce the reset period of the plasma display panel. The background flicker caused by the discharge operation. PDP is mainly used to display the accumulated charge through electrode discharge. Due to its large screen, high capacity and ability to display full-color images, it is the most promising flat display in the future. The basic principles and operation methods of the PDP are explained below. Fig. 1 is a side sectional view showing the structure of a cell (cel 1) in a conventional PDP. As shown in the figure, the PDP is mainly composed of two glass substrates 1 and 7 and their upper components. The cavity (C a V 丨 t ^) between the glass substrates 1 and 7 is filled with an inert gas such as N e, X e. The glass substrate 1 includes sustain electrodes X and scan electrodes Yi (extending in parallel with each other), an electric layer 3, and a protective film. The glass substrate 7 includes an address electrode (address e). lectrdes) Ai and the fluorescent material 9 _ are separated by a dividing wall (p & μ 丨 七 丨 〇nwa 1 1) 8 around the parent unit. Therefore, 'in each unit 10 Contains three electrodes, namely sustain electrode X and scan electrode Yi in parallel and address electrode Ai across it. Figure 2 shows a white block diagram of a plasma display using the PDP shown in Figure i.

Including control circuit (contr01 cirCUit) 11, γ scan driver (γ s c a n d r i v e r) 1 1 2, maintain driver (χ d r i v e r) 1 1 4 and address driver dynamic (address driver) 1 16. The control circuit i 10 generates timing information required by each driver according to a clock signal CLOCK, a data signal DATA, a vertical synchronization signal VSYNC, and a horizontal synchronization signal HSYNC provided externally. The clock signal CLOCK indicates the data transmission clock, the data signal data indicates the display data, and the vertical synchronization signal VSYNC and the horizontal synchronization signal bHsYNc are used to define the timing of a single day frame (scanning I inj). The control circuit 丨 丨 sends the display data and clock to the address driver 11 6 ′ and sends the relevant day frame control timing to the γ scan driver II 2 and the sustain driver 丨 4. It must be noted that the display-related data is sent from the control circuit 110 to the address driver 116, and when the y scan driver n2 sequentially scans each scan electrode Y1 ~ Yrl, the display data is written through the address electrode ^^ 111 In each unit. The detailed display of the operation and the control signals required for each electrode are described below with reference to Figures 3 and 4. Figure 3 shows that the conventional technology drives the PD to display a frame (frame). As shown in the figure, each picture frame is divided into 8 sub-fields SF1 to SF8. It must be noted that the meaning of the secondary field here is different from the field in the traditional cathode ray tube (CRT). The field in the traditional CRT is to scan and display the odd and even scan lines. The field of the PDP displays different gray scales for all scan lines. Each sub-field is composed of three operation periods, which are reset period R1 ~ R8, write period (address period) Al ~ A8, and sustain time (sustain

Explanation of the invention (3) 7: 2 31 /, 8; The setting period is used to clear the previous-second field _ 'remainder', u, and leave a fixed amount of wall charge in each unit (= / The period of writing people is discharged through the address (3 (1 (11 ^ 33 ^ Fge and the unit to be displayed is in the state of 0n). The wall charges are displayed on a single charge and a single charge (sustam discharge). Among them, the heavy periods R1 to R8 and the sustaining periods S1 to S8 process all the single i on pDp at the same time, and the writing periods A1 to A8 are sequentially performed for each scan. Each of the electrodes Y1 to γη = write operation. In addition, the display brightness is proportional to the sustain period W to S8. In the example in FIG. 3, the sustain periods S1 to S8 in each field SF and SF8. The length can be set to 1 ·· 2 ·· 4 ·· 8: 16 · 32. 64: 1 28 ratio to achieve 2 56 gray levels. · Figure 4 shows the conventional technology in a single field Timing chart of control signals on each electrode, where the signal on the address electrode 4 丨 is generated by the address driver 116, and the signal on the sustain electrode χ is controlled by the sustain driver 11 4 The signals on scan electrodes Υ1 ~ γη are generated by the scan driver 丨 2. As shown in the figure, each sub-field includes a reset period, a write period, and a sustain period. The signal waveforms of each period are described in detail below. And at the time point a during the reset period, the actions caused by the scan electrodes Yi ~ Yfl are set to ν, and the sustain electrodes X send write pulses with a voltage value of vs + vw, 2〇 L 'β where the voltage value VS + VW is greater than the discharge start between the sustain electrodes x and Yi

Discharge start voltage. Therefore, a global write discharge occurs between the sustain electrode X and the scan electrode Yi (total write 516013 V. Description of the invention (4) diSCharge) W. This discharge process will accumulate a positive ionization on the scan electrode y i and a negative charge will accumulate on the mountain, Lei Za, 1 :: Xunzi. The electric field caused by the accumulated negative charges and positive ions will offset the global write discharge W of the sustain electrodes for a short time.

Therefore, in susta.n d1scharge) Sortrit ft M '^^ t (t〇tal, a positive charge will be accumulated on the sustain electrode x) the negative process will accumulate a negative charge. House ions will be accumulated on the scan electrode Yi At time point c, the scan electrode sends a clear voltage δ lower than VS to 0V, and the sustain electrode X can also send / (eraSe Pulse) 203 on the address electrode Ai, which is also used to neutralize (NeUtralize) The address of part of the electricity ^ f. / In addition to the pulse wave 2 0 3 留下 ιι leaves the required wall electric Ho, after taking out the electrode γι ~ can be & 侗 μ t π electric Ho. This wall The charge allows the moon dagger to write at a lower voltage during the subsequent writing period, and then starts the writing period. The first scanning power is pulled to the voltage value X and sent to each scanning electrode Y1 ~ Yn. Starting from the point e between the scanner and the scanner, a voltage value Y skin (SCan pulse) 204 is sequentially sent to the address electrode Ai, and when the cell in the line is set to 0N, then: = address pulse胄 The display data of a scan should be written by the 5 writers in this unit. '&Amp; It will be on 516013 V. Description of the invention (5) All scans at f After scanning of the electrodes Y1 to Yn. ~ Each sustain electrode χ and scan electrode η are set to 0, and the holding period is wrong (¥ interval f and time g), and the same voltage value is input to Yi The sustaining pulse wave is 205. At this time, the unit where the electrode is turned on will display the brightness. It must be noted that the drive during the entry period = No. The shape is only an example '* Actual should = say and This case is different, but the basic principles are the same. The skin shape may be as described earlier. The length of the sustain period and the hypothesis shown include 51 in the day box. The sustain discharge period (by discharge) is shown in the figure below. In the field sn ~ SF8, two are maintained: the configuration is 2, 4, 8, 16, 32, 64, 128, 256. Therefore, the number of discharges for the sustain period during the display period in a two-frame box is 5ΐ〇χ2 = ι 〇2〇 .: Part of the discharge operation is the main part of the display image. On the other hand, actually, 2 to 3 discharge cycles are performed during the reset period, such as global write discharge, global sustain discharge, and clear discharge, so that Gang wall charge: not $, the discharge action during these reset periods will also produce shell, It will be slightly less than the brightness generated by the discharge during the sustain period. Roughly speaking, the brightness generated by three discharges during the reset period is approximately equal to the brightness generated by five discharges during the sustain period. Therefore, the ratio of the maximum brightness to the minimum brightness on pDp Approximately 1 0 20: 5 x 8 = 26: 1, which corresponds to the brightness of black. Therefore, the lower the brightness generated by the discharge during the reset, the better, so that the black day quality can be improved. Black Day quality is one of the important parameters of image display, so reducing the brightness effect caused by the discharge action during resetting is an important issue that must be resolved.

(6) In view of this, in view of this, the driving method and device of the main objective board of the present invention is to provide-the effect of a plasma display discharge operation on the brightness of the image = each field reset period according to the above For the purpose of the present invention, the present invention proposes a moving method, and the plasma display panel includes a tracing electrode and a tracing electrode, and maintains between ::: the flat electrode and the scanning electrode. To maintain the electric charge, all B are, all units in the plasma plasma display panel ... then use a smaller slope waveform from = 电 = 升 工 # and a small slope waveform can be written in a gradually increasing or decreasing field.

Rising 1 = wave can also use a smaller slope waveform, from the first to the second: Electricity 'reuses the larger slope waveform, which is paralleled by the second voltage! The part that boosts the voltage with the larger slope waveform can be tied to a large number. The part that boosts the voltage with the smaller slope waveform can avoid the edge becoming too bright, which affects Display quality. To avoid another problem, the present invention provides a driving device for a plasma display panel, which can be used as a signal source; circuit two is used to receive external display data and its related timing sequence 7 X, drive driving state, and is coupled to the control circuit for The driving address electrode is in the I state, and is coupled to the control circuit to drive the sustain electrode. The thunder κ 4 ^ gate sends a global write pulse to the sustain electrode, which is used to pass through the gate. The discharge action between the drawing electrodes generates the geoelectricity in the plasma display surface. This global write pulse wave has a larger slope waveform from page 9 516013. 5. Description of the invention (7) A voltage rises to the second voltage, and then rises from the second voltage to the third voltage with a smaller slope waveform, or The waveform is increased from the first voltage to the second voltage with a smaller slope waveform, and then increased from the second voltage to the third voltage with a larger slope waveform; and a Y-scan driver is coupled to the control circuit to drive the scan electrode. In addition, the present invention proposes a driving device for a plasma display panel, which differs in an X driver and a Y scanning driver. The X driver sends the first component pulse of the global write pulse to the sustain electrode during the reset period. The first component pulse of the global write pulse rises from the first voltage to the first voltage with a large slope waveform. Two voltages. The Y scan driver sends the second component pulse of the global write pulse to the scan electrode during the reset period, which drops to a second voltage with a smaller slope waveform, thereby maintaining the global write between the electrode and the scan electrode. The discharge action caused by the incoming pulse wave generates wall charges of each unit in the plasma display panel.

Example: The present invention is mainly aimed at the impact caused by the inferior quality of the conventional technology 2. It is proposed that it can be changed to cover this; J: a1 discharge operation for the entire range of the reset period; J1 driving method and: increase its accumulation The ability of the wall charges to cause the brightness produced by the discharge operation. The following is an example of the discharge process. A detailed description of each implementation of the present invention is shown in FIG. 1. First embodiment: FIG. 5 shows that in this embodiment, the address electrode Ai and the sustain electrode Xi are included in the 4: 5 period. Each electrode = timing chart. During the reset period, the control letter on the V field electrode γ 1) is processed at the same time. Second, a certain amount of wall charges are generated. Therefore, the unit on the line I indicates that 隹 refers to all the scan electrodes γ. The so-called scan electrode γ! Is again 5 yh, and the state will be set in the field where the scan electrode Yi is fed into _, and the main field is ended. In the unit of η = Qiao 'is used to clear the previous-: big, the :: he in the reset period of this field. Then, as shown in FIG. 5, a global write pulse 30 0 is written, so that the difference between the input voltage of the sustain electrodes X1 and the sustain electrode X is greater than the discharge start voltage between them, and the voltage between ° # and the scan electrode Yi. Charge. This global write pulse 3 0 0 and plume = are composed of two parts of the wall required for discharge generation. As shown in the figure / different technology, its waveform is increased from the first voltage (0V) by the rate waveform. The pulse wave 300 is gradually increased from the second voltage to the second vertical voltage in a large slope. 'Wave a voltage again with a smaller slope. In this embodiment, the second 516013 V. Description of the invention (10) The voltage can be set to 18〇v, and the third voltage can be set to 36Ov. Then, as described above, the scan pulse Y1 is sequentially fed with the clear pulse wave 301, and the main pulse wave 302 is removed. Then, it enters the subsequent writing period and maintenance period t. It should be noted that the electrode control number in the reset period in FIG. 5 is not used to limit the present invention. For the well-known latent phase two: s, you can According to its display principle, it can be modified to different degrees. The main feature of this embodiment is that the global pulse wave 300 is written, so its waveform will be described in detail below. According to a larger slope waveform, the first part of the global writing pulse 300 is increased from the first voltage (0v) to the second 1 The function is to accumulate a large amount of wall charges, which is also the purpose of this pulse wave. . The second part of the global write pulse 300 is based on a small ramp wave, which is raised from the second voltage to the third voltage. Its role is also to accumulate wall voltage /, but because its slope of voltage rise is small, the discharge effect is relatively Learn. So: "Because" is bright. In summary, using this global write pulse waveform of 300, on the one hand, it can still accumulate a lot of wall charges, and it will not cause too bright background flicker. Figure 6 shows this implementation. The driving block diagram of the plasma display panel in the example 'its basic structure is roughly the same as the conventional technology. The driving device includes a control circuit 11 0, an address driver 11 6 and a maintenance driver 丨 24 with a dagger $ 22. Control circuit 110 receives the display data da: provided by the outside, and transmits timing data such as the day guard pulse CLOCK, and the vertical synchronization signal VSYNC and water HSYNC to send it to each driver. Address driver / driver 1 = Then, drive during writing The address electrode Ai writes the display data into each scan unit. The scan driver 1 22 is responsible for driving the scan electrode η;

516013 V. Description of the invention (11) The driver 1 2 4 is responsible for driving the sustain electrode X. As shown in Fig. 5, the sustaining drive] 24 writes the global pulses sent in between, firstly, the voltage is reset to the second voltage (0V_ > 180V) in the reset period of = ^%, and then The electric voltage rises to a third voltage (180V_ > 360V), and uses a discharge operation between the two electrodes X and the scan electrode γ i to hold wall charges. F wood produces a small slope waveform in each early TL, ㈣W writes the pulse wave 300 in the whole domain shown in Fig. 5; 疋 first continues with a relatively large slope 丨 Habdan slowly rises, and the basin wave Open two ΪΪ: 幵 'and then with a relatively small slope Surname: Shi: Similar to the shape of a quadratic curve (outward convex). The dimensional synthesis approximates this waveform. Formula can use step voltage. According to the above, the PDp driving method of this embodiment is mainly a modified global write pulse, which enables it to accumulate a large amount of wall charges, which causes excessive brightness during discharge and affects day f. * To achieve the above two, the waveform of the incoming pulse 'only needs to modify the part of the original χ driver, which can generate the required waveform, so the additional cost + 20% Example: This example of bismuth is different from the basic driving method and driving device of the first embodiment. The difference is that the waveform of the pulse wave 300 is written in the entire domain. The pulse wave 30 is written in the vertical region of the first embodiment. The first part of 0 rises from the third voltage to the second voltage with a larger slope waveform, and the second part rises with a smaller slope waveform

5. Description of the invention (12) to the third voltage, and the slope of the voltage rise in the second part is gradually decreasing. In this embodiment, several different waveforms are used to illustrate that the variability plants can all achieve the purpose of the present invention.

Fig. 7a shows the first variation waveform of the global write pulse 300 in this embodiment. As shown in Figure 7a, the global write waveform 300 rises from the first voltage to the first voltage with a larger slope waveform in the first part, and rises to the second voltage with a smaller slope waveform in the second part 77. It is different from the first embodiment in that the slope of the voltage rise in the second part is gradually increasing, because the waveform shows a shape where the quadratic curve is concave inward. The global write wave 300 of this waveform can also accumulate a large amount of charge on the one hand, and on the other hand, avoid too much brightness during the pulse process to affect the quality of the day. Fig. 7b shows the second iron-differential waveform of the global write pulse 300 in this embodiment. Different from the first embodiment, the global writing 300 in Fig. 7b still distinguishes the first part from the second part, but first rises with a smaller slope & shape, and then rises with a larger slope waveform (Almost vertical pulse), the shape of the waveform is concave in the quadratic curve. The whole of this waveform, this wave of 300, can also accumulate a large amount of charge on the one hand, and avoid 2 ″, which emits too strong brightness during the pulsed electricity process, which affects the quality of the day. It does not specifically limit the actual writing of the global waveform, but it can meet the spirit of the present invention as long as it is mentioned in at least two stages. Electricity & 'Third embodiment: This embodiment is based on the concept of equivalent waveforms. Implementing the first embodiment

Description of the invention (13) 1 The fifth figure of the embodiment, writing the pulse wave on the sustain electrode X in the whole area is relatively complicated and the cost is relatively high. In this case: two =, the two parts of the global write pulse 300 are generated by the sustain driver 124 and the driver 122 and sent to the sustain electrode χ and the scan electrode Yi, respectively. This simplified waveform generating circuit is hunted. FIG. 8 shows a timing chart of the control signals on the bit sustain electrodes X and the scan electrodes Yi during the reset period of the sub-field in this embodiment. For example: No, the original global write pulse 300 is based on the component pulse 300a (the first electric I is rapid: the first-force of the "three-electricity" slowly drops to the fourth voltage)- Composition: wave; ofi electric effect is the same as the first embodiment. Its waveform component, and the larger slope of the-^ Qiaoyuan global writing pulse 300, and the smaller component of the pulse wave 300b is equal to; f + shirt all & the smaller slope wave forms the writing pulse 300 The waveform of Figure 8 needs to be ^ = From the perspective of the circuit, it is easy to produce the driving waveform of Figure 24.
