Universal power timing controller for a plasma display panel

摘要

A universal Power Timing Controller (PTC) unit intended for controlling the image memory and the line power boards of a Plasma Display Panel (PDP) is discribed. The PTC is responsible for generating control signals for the power boards of the PDP in order that they produce the correct waveforms (e.g. priming, erasing, addressing, sustaining . . . ) to be applied on the lines of cells of the PDP and control signals for the image memory of the PDP. According to the invention, the PTC has a fully programmable structure. The PTC comprises programmable memories or LUTs (look-up tables) in which the data defining the display mode of the panel and data defining elementary control signals required by the line power boards for processing operations associated to each phase period of the frame are stored.
