An apparatus and method for driving a plasma display panel wherein an initializing discharge can be weakened to lower a dark room brightness and an initialization time can be shortened to permit a single scanning. In the apparatus, a sensing device senses an electrical signal with an initialization waveform applied from a voltage source to a display panel. A controlling device controls said electrical signal with an initialization waveform applied from the voltage source to the display panel by the sensed electrical signal.

Apparatus and method for driving plasma display panel

An energy recovery apparatus including a sustaining voltage source for applying a sustaining voltage to a first electrode and a second electrode formed on an upper substrate; a equivalent capacitive load formed between the first electrode and the second electrode; and a power source capacitor disposed between the sustaining voltage source and a ground voltage source, for being charged with a voltage charged in the equivalent capacitive load and preventing a voltage drop phenomenon when a voltage of the sustaining voltage source is applied to the equivalent capacitive load.

Apparatus and method for energy recovery

A plasma display panel driving method that is adaptive for improving contrast. In the method, at least one of the first and second electrodes keeps a floating state in an initialization period of at least one sub-field of a plurality of sub-fields.

Plasma display panel and driving method thereof

A plasma display panel driving method and apparatus that is capable of driving a PDP at a high speed as well as improving the contrast. In the method, at least one selective writing sub-field is used to turn on discharge cells selected in an address interval. At least one selective erasing sub-field is used to turn off the discharge cells selected in the address interval. The selective writing sub-field and the selective erasing sub-field are arranged within one frame.

Method and apparatus for driving plasma display panel using selective writing and selective erasure

A plasma display panel driving apparatus that is capable of reducing the number of optical conductive devices. In the plasma display panel driving apparatus, a first controller generates control data for controlling the driving integrated circuits. A second controller drives the first controller. An optical conductive device for transmitting a light signal from the second control to the first control.

Plasma display panel driving apparatus

A separate voltage driving apparatus for a plasma display panel that is capable of restraining an abnormal brightness caused by a characteristic deviation of the panel as well as preventing a damage of switching devices caused by an overcurrent. Any one of sustaining drivers of the apparatus can include a writing voltage generator, a sustaining voltage generator that generates pulses, each of which has a voltage level and a pulse width required for sustaining the writing discharge of the entire cells between the first and second electrodes, having a phase contrary to and being synchronized with each other, and an erasure scanning voltage generator. A voltage driving apparatus can further include a voltage recovering stage and a voltage input/output stage.
