Considerable effort has been put into the development of display technologies such as liquid crystal displays, vacuum fluorescent displays, CRTs and so on. In the aviation field in particular, much ergonomics effort has been expended on specific aspects of the display technology such as the contrast ratios, effects of glare, font and so on. However, very little is known about the ergonomics aspects of new display technology applications in cars. In a series of experiments reported in this thesis three electronic display designs for a car instrument panel comprising speedometer, tachometer and minor gauges were tested by potential users.
