Patent ID: 6853149

Claim:
An apparatus for automatically adjusting a reset ramp waveform of a plasma display panel, comprising: a sensor which senses image information related to a gradient adjustment of the reset ramp waveform of the plasma display panel; a look-up table which stores gradient reference data of the reset ramp waveform corresponding to digital date value of the image information related to the gradient adjustment of the reset ramp waveform; a control circuit which converts the sensed image information into digital data, reads the reset ramp waveform gradient reference data corresponding to the converted digital data value of image information from the look-up table, and converts the read gradient reference data into an analogue signal; and a ramp waveform generating circuit which changes a gradient of the reset ramp waveform according to a level of the reset ramp waveform gradient reference signal which is converted into the analogue signal.
