Abstract

A brightness control using modular waveform techniques is disclosed which enables a wide range of brightness control not affected by the order in which functions are executed. 512 cell parallel addressing is used, enabling the border electrodes to be discharged only once during each extended cycle, thus lowering the intensity of light emitted from the borders by at least a factor of 5. 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.
