  • Patent number: 7580008
    Abstract: A method of driving a plasma display panel (PDP) and an apparatus for carrying out the method. The PDP includes address electrodes with first electrodes and second electrodes intersecting the address electrodes. Gray-scale levels being represented by combinations of sub-fields, each sub-field having a reset period, an address period, and a sustain-discharge period. The different gray scales are achieved not only by modifying the voltage waveforms in the sustain-discharge period but also by modifying the voltage waveforms in the reset period, allowing for better control over gray scales and better contrast. Different sub-fields can have different voltages applied during the reset period which affects the luminance of the image displayed. A circuit for making the above voltage waveforms is also presented.

  • Publication number: 20090146925
    Abstract: A PDP address data processor, a method thereof, and a recording medium for storing a program used to perform the method. The address data processor generates subfield data corresponding to RGB input video data, divides them into two sets of subfield data, and stores them in a frame memory using rising and falling edges of a reference clock signal of a frame memory. The address data processor reads and arranges the stored subfield data using the rising and falling edges to generate address data for representing gray on the PDP. The address data processor uses an RGB mixing algorithm for selecting two different video data from among the RGB input video data to select video data, and generates the subfield data corresponding to the selected video data.
