A method for the conversion of a TV analog video signal into binary half tone like data simulating the gray level apearance of conventional television on a plasma display device, is presented in the IBM Technical Disclosure Bulletin 22, 166-167 (June 1979). This technique enables TV imagery to be displayed on an all-points addressable, AC plasma display device. The varying dot patterns simulate the appearance of varied levels of gray on a normally two-state device. If the TV data stream is written in typical raster form, left to right, top to bottom, and the screen then erased prior to writing the next image frame, the result is an uneven flicker over the display surface. The upper portion of the display flickers slightly, while the lower portion flickers substantially more due to the difference in the write and erase speeds.
