An ITO/BaTi03 /ZnS:Mn/black insulator/Al ac thin film electroluminescent display device with high display viewability has been developed for the application in the automotive dashboard display.The device consists of back and front insulating layers and a ZnS:Mn luminescent layer. The back insulating layer consists of the GaAs light absorption layer and the Hf O2 insulating layer. This device exhibits high contrast ratio (greater than 2:1) in an ambient illumination of 10,000 ft-candle at 125 ft-L brightness.This high contrast device also shows low power consumption due to placement of the black GaAs absorption layer between Hf O2 insulating layers in the back side. This is a significant improvement over previously published results. Detailed experimental results will be presented.
