An alternating current generator for controlling a plasma display screen (PLATMA DISPLAY SCREEN)

摘要

In a plasma display screen, there is a circuit that alternately applies positive and negative voltages to the screen or panel's common capacitance for resetting. In the current path, there is an inductance to guarantee energy recovery for the total capacitance. The purpose is to improve the driving and eliminating process of pixels in the circuit. The capacitor Cp is periodically connected to the third operating voltage whose voltage UCp at the capacitance Cp through the third switch T3 has a zero voltage of one period between the positive and negative voltages. Particularly in control circuits for plasma display screens for television receivers.
