Abstract
A display has a matrix array of cells formed in a silicon plate and each containing a tungsten strip filament. The cells are filled with a halogen gas and are sealed by a double-glazed window with an infra-red reflecting filter to reflect heat back into the cell while allowing the transmission of visible radiation. The rear of the plate is treated to make it microporous and reduce its thermal conductivity.
