Problems solved by technology

[0018] As mentioned above, in order to provide a stable holding voltage, when the electrostatic capacity of the capacitor Cs increases, the gap between the electrostatic capacity of the capacitor Cp increases, which not only causes a decrease in the energy recovery rate, but also makes it difficult to set the optimum Capacitor Cs electrostatic capacity

Embodiment Construction

[0036] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0037] Figure 5 It is the circuit diagram of the energy recovery line part of the present invention, Image 6 It is the voltage waveform diagram of the plasma display connected to the energy recovery circuit part of the present invention.

[0038] In this case, drawing numeral 510 is an energy supply / recovery unit including a capacitor Cs; drawing numeral 520 is a sustain voltage supplying unit including a capacitor Cvs.

[0039] The energy recovery circuit of the present invention adds a closing part 530 to the existing energy recovery circuit to separate the voltage source Vs and the capacitor Cs, so that the capacitor Cs only operates energy recovery and supply functions. That is, the closing part 530 of the present invention is a diode DB, the anode of which is connected to one end of the first switch S1, and the cathode of which is connected t...

Description

【Technical field】 [0001] The present invention is an invention related to a plasma display driving device, more specifically, an invention related to a plasma display driving device including an energy recovery circuit. 【Background technique】 [0002] figure 1 It is a structural diagram of a general AC type surface discharge plasma display. Such as figure 1 As shown, a general AC surface discharge plasma display includes a front substrate 122 and a back substrate 124 made of transparent glass materials that are balanced and opposed to each other at intervals of 100-200 μm. At this time, in order to maintain a distance from the front substrate 122 , the rear substrate 124 forms a balanced partition wall 126 by thick film printing technology. The interval between these partition walls 126 is 400 μm, and the width of each partition wall 126 is 50 μm. [0003] In addition, in order to operate the addressing (Addressing) function, between the adjacent partition walls 126, 127...
