Description of the invention: » [Technical Field of the Invention] The present invention relates to a driving circuit, particularly a driving circuit of a plasma display panel (PDP). [Prior Art] In recent years, 'Plasma Display Panel (PDP), Liquid-Crystal Display (LCD), and electroluminescent display (EL display) The advantages of its thin and light body make the demand for flat matrix displays increasing, and gradually replaced the trend of cathode ray tube (CRT) displays. A flat panel display of this type generally charges the electrodes by giving their electrode voltages, causing the panel to discharge to produce visible light, and the function of displaying the pupils by the accumulation of visible light. • In the electro-convergence display panel, the amount of charge accumulation on the electrode is determined by the corresponding display > material' and the sustaining discharge pulse is applied to the pair of sustain electrodes. The display is caused to emit light. In the case of a plasma display panel, it is necessary to apply a very high AC pulse voltage to the electrodes' and usually the applied high voltage pulse wave will cause the panel to discharge for a few microseconds, and consume power 'if the number of pulses is higher More, the power consumption is greater. Therefore, the power consumption of the plasma display panel has become a problem that manufacturers must face – and therefore the goal of achieving energy recovery (or energy conservation) has become a must for all manufacturers. There are a number of published designs or patents that disclose 1335012 various methods and apparatus for energy recovery of plasma display panels. For example, Kishi et al., in the "Drive Unit for PZanar - Noisy" patent of U.S. Patent No. 5,828,353, discloses an energy recovery drive circuit for a flat panel display. Please refer to FIG. 1 , which is a circuit diagram of a conventional driving circuit 1 用于 for a plasma display panel. The plasma display panel can be represented by an equivalent capacitor on the circuit. The driving circuit 100 includes four switches S1 S S4 for controlling current transfer, an X-side energy recovery circuit 11A and a γ-side energy recovery circuit 12A for equivalent to the X side and the X side, respectively. Capacitor charging and discharging. S5~S8 are switches for controlling current direction; D5~D8 are diodes; VI and V2 are two voltage sources; C1 and C2 are capacitors for charging and discharging the panel, and L1 and L2 are resonant inductor sides The energy recovery circuit 110 includes a charging path of a plasma display panel composed of a switch S6, a diode D6 and an inductor L1, and an electro-concentration panel formed by the inductor L1, the diode D5 and the switch S5. Discharge path. Similarly, the γ-side Φ energy recovery circuit 120 includes a charging path of a plasma display panel composed of a switch S8, a diode D8, and an inductor L2, and an inductor L2, a diode, and a switch. The discharge path of the plasma display panel formed by S7. Please refer to FIG. 2, which is a flow chart of the conventional driving circuit 1 of FIG. 1 when generating the sustain pulse of the equivalent electric valley, and the flow includes the following steps: Step 200: Start; " 210: Keep the potentials of the X side and the γ side of the equivalent 7 1335012 capacitor as the stack potential by turning on the switches S3 and S4 and turning off the other switches. Step 220: By turning on the switch S6 and aligning and turning off the other switches Capacitor a charges the X side of the equivalent capacitor and maintains the potential on the γ side at the ground potential'. Then the potential on the X side of the equivalent capacitor is boosted to ^. Step 230: Turn on the switch SuS4 and turn off the other switches Then, the plasma display panel generates a discharge. The potential of the 电容 side of the equivalent capacitor is maintained at % and the potential of the Y side of the equivalent capacitor is maintained at the ground potential. Step: By turning on the switches 85 and 84 and other _ , discharge the equivalent capacitor through the χ side and maintain the potential of the 电容 side of the equivalent capacitor as the ground potential, so the potential on the X side of the equivalent capacitor is reduced to the ground potential; Step: by turning on the switch 83 and Branch and turn off other switches to maintain equivalent power The potential of the X side and the Υ side is the ground potential; 260 ·· By switching off S8 and S3 and depending on other traces, the capacitor a charges the Y side of the equivalent capacitor and maintains the potential of the χ side at the ground potential 'The potential on the gamma side of the equivalent capacitor is then increased. · Step 1 by turning off 82 and 83 and turning over the other _, the occupation display panel generates a discharge. Then the potential on the γ side of the equivalent capacitor is maintained at V2. The potential of the X side of the equivalent capacitor will be turned to the ground potential; Step (10): By turning on the switches S7 and S3 and turning off the other switches, the equivalent capacitance is discharged through the γ side, and the potential of the 电容 side of the equivalent capacitor is maintained. Ground potential, so the potential of the γ side of the equivalent electric valley will be reduced to the ground potential; Step I maintains the potential of the X side and the Y side of the equivalent capacitor as the ground potential by means of ·_S3AS4 and other switches;丄j:) 丄厶丄j:) 丄厶End step 295: To control the third picture, the third picture shows the x, γ _ voltage of the equivalent capacitance and the control signal of the S1~S8 with the time gate Timing diagram of M1~M8. The L vertical material of the horizontal axis table shows the potential. It should be noted that when the S1~S8 money is counted, when the two j signals M1~M8 are at a high potential, the bay will open (form a closed circuit) so that the electric power passes through it; and when the corresponding control signal If ~(10) is low, it will turn off _彡) so that current cannot pass through it. Therefore, it can be seen that the energy recovery circuit of the conventional plasma display panel provides two mutually independent charging/discharging paths (charging path and discharging path) to charge/discharge each side of the equivalent capacitance, respectively. Even if the X ship γ_ two positive voltage pins are used to supply the voltage to the equivalent capacitance separately, the prior art still has to be set by the capacitor _ (4) on both sides of the capacitor and two positive voltage sources. The connection required for the energy recovery circuit of the prior art towel is not huge, and the cost of the energy recovery circuit of the plasma display panel is not easily reduced, thereby reducing the market competitiveness of the product. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a drive circuit for a plasma display panel to improve the problems of the prior art described above. Briefly, the present invention provides a drive for a plasma display 9 1335012 panel having an energy recovery function.
