ELECTROLUMINESCENT FERROELECTRIC (ELF) SOLID STATE DISPLAY
Abstract
Research continued in the fabrication of electroluminescent ferroelectric (ELF) cells. The cells are prepared on aluminum substrates using BaTiO3 in polyvinyl chloride with a solids ratio of 24:1 as a barrier layer and VB206P in ME-34 with a solids ratio of 3:2 as the emitting layer. The secret of fabrication of good cells is the proper application of the barrier layer which must be smooth for good leakage characteristics and light output. A number of life tests on cells indicate that an increase in life will result if the screen is operated in a desicated atmosphere. A number of groups of switches were made and a final design was selected. With respect to sandwich structure, the first sandwich laminates were started. An analysis was made of the matrix configuration and requirements for the electrostrictive switch in the ELF application.
