A PROCESS SAID, to improve the readability of avionics displays and tackles the so-called "white-shirt effect", often encountered by pilots, has been developed by Crystaloid, of Ginsbury, UK.

The firm says that the process relies on a technique called "thin-film index matching" to achieve improved uniformity between indium/tin oxide (ITO) electrodes which carry electrical current in the liquid-crystal display (LCD) and the display's background.

The "white-shirt effect" occurs if the pilot sees ITO electrodes when light is reflected from his white shirt, a potential cause of misinterpretation of display data.

The "index-matching" coating is applied over ITO and non-ITO areas to match the reflections generated in all portions of the display.
