PLASMA DISPLAY PANEL CONTROL

摘要

Complex waveforms used to control a plasma matrix panel are formed as sequences of common elemental waveform modules stored in a ROM. These modules are combined in various orders into strings capable of independently performing various functions on the plasma panel, including a wide range of brightness control. Large scale parallel addressing is accomplished by forming a string of several sustain modules, followed by a write or erase module. The use of 512 cell parallel addressing enables border electrodes to discharge only once during each extended cycle, thus lowering the intensity of light emitted from the borders by at least a factor of five. An erase before write technique is described which allows an erase operation to be inserted into a write function without extending the length of the write function, thus doubling the maximum data rate of the plasma panel display system.
