Design and reliability assessment of an avionics TFT-LCD display

In avionics application it's fundamental that each system, sub-system or a component achieves a high level of reliability. To this aim, reliability prediction and an accurate test planning are required in the design phase in order to avoid undesirable fault or failure during the operating life cycle of any aeronautics equipment. In this paper, a research activity concerning the design and reliability assessment of TFT-LCD for avionics application are presented. The results obtained by the development, characterization and reliability analysis of a customize display which will be installed in a military aircraft cockpit are discussed. Being the device under test an innovative display, it's fundamental an evaluation and analysis of the reliability performances. Then some test on the display has been performed to validate the customizing process.
