Abstract
An enhanced light pen capability for plasma display panels is provided by applying specially timed scan write and scan erase pulses to the cells of the panel, the pulses being shaped and positioned relative to the normal sustain pulse sequence such that a light pulse is emitted, while avoiding any but transient modification of the cell wall voltage. The light pulse is detected by a light pen of standard design. Dynamic keep-alive circuitry for applying location-dependent priming enhances the operating margins.
