Problems solved by technology

[0027] In addition, the long-term increase / fall time of the display voltage in the traditional energy recovery circuit may cause the discharge of the display during the energy recovery interval (ie, the increase / decrease interval of the display voltage)
This may drop the display voltage causing the hold switch S c hard switching and thus cause large switching losses when the switch is turned on

Abstract

A PDP driving apparatus includes a sustain discharge unit including a first switch and a second switch connected between a first voltage and second voltage and having a contact connected to one terminal of a panel capacitor, and a third switch and a fourth switch connected between the voltages and having a contact connected to other terminal of the panel capacitor, for maintaining either terminal voltage at the first voltage or the second voltage; and a charge / discharge unit including a first inductor and a second inductor connected to the terminals of the panel capacitor, for boosting a current to a level to store energy in the first inductor and the second inductor while either terminal voltage of the panel capacitor is maintained at the sustain discharge voltage, and inverting the polarity of either terminal voltage using the stored energy.

Description

technical field [0001] The present invention relates to a plasma display panel (PDP) and a device and method for driving the plasma display panel. In particular, the invention relates to an energy recovery circuit directly acting on plasma display discharge and a driving method thereof. Background technique [0002] In recent years, flat displays such as liquid crystal displays (LEDs), field emission displays (FEDs), PDPs, and the like have been actively developed. The PDP is superior to other flat panel displays due to its high brightness, high luminous efficiency, and wide viewing angle. Therefore, PDP is a preferred large screen larger than 40 inches, which can replace traditional monitors. [0003] A PDP is a flat panel display that displays characters or images using plasma generated by gas discharge. Depending on its size, a PDP includes several scores to millions of pixels arranged in a matrix pattern. Such a PDP may be classified as a dire...
