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, a flat-panel display such as a plasma display panel (PDP), a liquid crystal display (LCD), and an electroluminescent display (EL display) has a thin machine. With the convenience of display, consumers are increasingly demanding flat matrix displays, and there is a tendency to gradually replace cathode ray tube (CRT) displays. A flat panel display of this type generally charges the electrode by first giving its electrode voltage, causing the panel to reach a discharge state to generate visible light, and the cumulative light intensity of visible light is used to achieve the gray scale of the display screen. In the plasma display panel, the amount of charge accumulation on the electrodes is determined by the corresponding display negative material, and the sustaining discharge pulse is applied to the pair of sustain electrodes. In the case of a plasma display panel, it is required to apply a very high AC arc voltage to the electrodes, and the high voltage pulse width normally applied can cause the panel to discharge normally and emit light for several microseconds. Since the panel illumination intensity is determined by the number of pulse waves, the more the pulse wave, the stronger the light intensity, but the greater the energy loss. Therefore, the power consumption of the plasma display panel becomes one of the problems that manufacturers must face. Therefore, how to recover the energy supplied when the panel is charged to change 6 1345754 - the problem of power consumption of good panels has become a must-have for all sides. At present, there have been many disclosed designs or methods for exposing various types of energy sources for electric panels. For example, Kishi et al. disclose the energy recovery drive circuit for a flat panel display in the "Drive Unit for Deceased Coffee Meal" in Patent Publication No. 5,828,353. Please refer to Figure 1 for the first figure. The circuit diagram of the driving circuit Lu (1) 0 of the plasma display panel. The plasma display panel can be represented by an equivalent electric capacitance Cpanel on the circuit. The driving circuit 100 includes four switches S1 S S4 for controlling current. The transmission, the X-side energy recovery circuit 11 () and the γ-side energy recovery circuit 12A are used to charge and discharge the equivalent capacitance Cpanel via the X side and the Y side, respectively. S5 to S8 are switches for controlling the current direction; D5~D8 are diodes; V1 and V2 are two voltage sources; C1 and C2 are capacitors used to charge and discharge the panel, and L1 and L2 are resonant inductors. X-side energy recovery circuit 11〇 contains one A charging path formed by the switch S6, the two-pole φ body D6 and the inductor L1, and a discharge path formed by the inductor L1, the diode D5 and the switch S5. Similarly, the γ-side energy recovery circuit 120 includes a Switch S8, diode 〇8 and inductor L2 A charging path is formed, and a discharge path composed of an inductor L2, a diode D7, and a switch S7. Please refer to FIG. 2, and FIG. 2 is a diagram showing the equivalent capacitance Cpanel of the conventional driving circuit 100 of FIG. A flowchart for maintaining a pulse wave, the flow of which includes the following steps: Step 200: Start; 7 1 ^45754 - Step 210: Step 220: Step 230: Step 240: Lu Step 250: Step 260: Step 270: By turning on the switch S3 and S4 turn off other switches to keep the potential of the X and Y sides of the equivalent capacitor Cpanel at ground potential. By turning on switches S6 and s4 and turning off other switches, the capacitor C1 is on the X side of the equivalent capacitor Cpand. Charging, and maintaining the potential of the 丫 side at the ground potential, so the potential of the 电容 side of the equivalent capacitor Cpand will be raised to VI; by turning off S1 and S4 and paying other off, the display panel will generate a discharge. The potential of the side of the SCpanel is maintained at VI and the potential of the gamma side of the equivalent capacitor Cpanel is maintained at the ground potential; by turning on the switches S5 and S4 and closing the other turns, the equivalent capacitance Cpand is discharged via the helium side, and Keep the γ side of the equivalent capacitor Cpand The potential of the potential, so the equivalent of electricity, Cpand's charge will be stored on C1 'so the potential on the χ side will be reduced to the ground potential; by turning on Μ S3 and S4 and closing the other off, to maintain the equivalent. Capacitance Cpanel The potential of the X side and the γ side is the ground potential; by turning on the switches S8 and S3 and turning off the other switches, the capacitor C2 charges the γ side of the equivalent capacitor Cpanel, and the potential of the ❹ side is maintained at the ground f position ' The gamma meter potential of the granule Cpane 会 will be raised to V2; by turning on the S2 and S3 and paying other switches, the galvanic display panel will discharge, so the potential of the capacitor Cpan, Y side will be maintained at V2 and the particle capacitance Cpand The _ _ potential will be maintained: 8 U45754 ' Ground potential; • V 280. By turning on the switch 87 and phantom and turning off other switches via the γ side

等效電容放電，並保持等效電容Cpanel的X 側之電位為接地電位，於是等效電容Cpanel的電荷會 儲存到C2上，因此γ側的電位會被降至接地電位； 步驟290 :藉由開啟開關S3及S4並關閉其他開關，來保持等效 電容的x側與Y側之電位為接地電位；以及 步驟295··結束。 凊參考第3圖，第3圖為等效電容Cpanel的X、Y兩側電壓 以及用來控制開關S1〜s·8之控制訊號Ml〜Μ8的Β寺序圖。其中 橫^表示時間，縱軸表示電位。需注意的是，開關S1〜S8係設計 成當對2的控制訊號M1〜M8為高電位時，則會開啟(形成卿 以使電流得以從其上通過；而當對應的控制訊號Ml〜M8為低電 •位時’則會關閉(形成開路)以使得電流無法從其上通過。 由此可知，習知電漿顯示面板的能源回收電路提供兩個相互 •獨立的充電/放電通路，來分別對等效電容Cpanel的每-面進行充 ^放電的動作。此外，該面板等效電容的每-側的充電/放電通路 白/員採用f谷來完成充放電的m先前技術中的能源 回=電路所需的疋件會非常巨大。如此一來，習知電聚顯示面板 的此源回收電路的成本並不容易降低，轉低了產品的市場競爭 1345754The equivalent capacitor discharges and maintains the potential of the X-side of the equivalent capacitor Cpanel as the ground potential, so the charge of the equivalent capacitor Cpanel is stored on C2, so the potential on the γ side is reduced to the ground potential; Step 290: The switches S3 and S4 are turned on and the other switches are turned off to maintain the potentials of the x-side and the Y-side of the equivalent capacitor at the ground potential; and the step 295·· ends. Referring to Fig. 3, Fig. 3 is a diagram showing the voltages on the X and Y sides of the equivalent capacitor Cpanel and the control signals M1 to Μ8 for controlling the switches S1 to s·8. Where horizontal ^ represents time and vertical axis represents potential. It should be noted that the switches S1 S S8 are designed such that when the control signals M1 M M8 of the pair 2 are at a high potential, they are turned on (formed to enable current to pass therethrough; and when the corresponding control signals M1 to M8) When it is low, it will turn off (form an open circuit) so that the current cannot pass through it. It can be seen that the energy recovery circuit of the conventional plasma display panel provides two mutually independent charging/discharging paths. The operation of charging and discharging the surface of each of the equivalent capacitors Cpanel is performed separately. In addition, the charge/discharge path of each panel of the equivalent capacitance of the panel is used to complete the charging and discharging of the energy of the prior art. Back = the required components of the circuit can be very large. As a result, the cost of this source recovery circuit of the conventional electro-convex display panel is not easy to reduce, which reduces the market competition of the product 1345754
