Abstract:
An erasing method and apparatus for a plasma display panel that is capable of minimizing spurious wall charges left after an erasing discharge. In the erasing method, an erasing signal taking a ramp waveform shape is applied to any one of first and second electrodes for alternately causing a sustain discharge. A voltage of said erasing signal is sustained at a voltage upon erasing discharge after the erasing discharge caused by said erasing signal.
Abstract:
A method and apparatus of driving a plasma display panel that is adaptive for making a stable operation at a low temperature. In the method, a first driving waveform is applied to sub-fields at a temperature more than a low temperature. A second driving waveform different from the first driving waveform is supplied to the sub-fields at the low temperature.
Abstract:
A method and apparatus for driving a plasma display panel for preventing and a spot misfire and a miswriting is disclosed. In the method, wall charges are formed at a discharge cell in an initial period. The discharge cell selects discharge cells in an address period. A wall charge control period is arranged between said initialization period and said address period. A wall charge distribution at the discharge cell is controlled in the wall charge control period. A sustain discharge is caused at discharge cells selected in said address period in the sustain period.
Abstract:
A method of driving a plasma display panel that is adaptive for improving a picture quality. In the method, first and second sustain pulses having a different width during the sustain period are alternately applied to the first and second row electrodes.
Abstract:
A method and apparatus for driving a plasma display panel that is adaptive for improving a sustain driving margin. In the method and apparatus, the number of sustaining pulses is set in response to an average picture level. A period of the sustaining pulse is set in proportion to said average picture level.
Abstract:
A method and apparatus of driving a plasma display panel that is adaptive for making a stable operation at both a low temperature and a high temperature. In the apparatus, a scan driver supplies a rising ramp waveform in a set-up interval and a falling ramp waveform in a set-down interval. A temperature sensor senses a driving temperature of the panel to generate a bit control signal. A set-down control signal generator generates a control signal such that an application time of the falling ramp waveform can be controlled in correspondence with said bit control signal and for applying the control signal to the scan driver.
Abstract:
A method of driving a plasma display panel wherein a selective inversion system is used to perform an address operation. In the method, a reset step makes an entire write discharge of the cells to form wall charges. An address step makes an address discharge of specific cells of the cells undergoing said entire write discharge to invert the polarities of the wall charges of said specific cells and to keep the polarities of the wall charges according to said entire write discharge as they are at the remaining cells excluding said specific cells. A sustain step makes a sustain discharge of only the specific cells having the inverted wall charge polarity by a sustain pulse. Accordingly, a data is written by the selective inversion addressing method to permit a high-speed driving and to prevent a contrast deterioration.
