Abstract
The display panel comprises a gas-filled envelope, made up of a hermetically sealed base plate and face plate, which includes electrodes disposed to form a dot matrix array of cell regions. The array of cell regions includes D. C. cells in which the electrodes are in contact with the gas, and A. C. cells which are insulated from the gas. The electrodes are disposed both on the base plate of the panel and the face plate, and each cell region includes both a D. C. cell and an A. C. cell which cooperate to provide the desired operation. In operation of the panel, sustaining pulses are applied to the A. C. portion of a cell region, with the potential of the sustaining pulses being insufficient in amplitude to cause glow. The A. C. cells are caused to produce visible glow by first causing the D. C. cells associated therewith to glow, and then the glow of the A. C. cells is sustained by the sustaining pulses.
