In recent years there has been increasing use of solid state displays for car instrumentation starting from small car clocks and trip computers to the latest large dashboard with a relatively higher density of information ans colour, sometimes in combination with voice synthesis. Originally, light emitting ('active') display technologies have been employed such as electroluminescence (EL), gas discharge (GD) or vacuum fluorescence (VF). By comparison, liquid crystal displays (LCD's) are passive panels usually visible by reflection of ambient light and so appeal to designers wishing to avoid sunlight washout of the active displays. Unfortunately, they are less easily lit at night and balancing day and night parameters compatible with operational performance over a wide range of environmental stresses is something of a compromise. The interaction between requirements for good optical appearance and practical limitations of fabrication will be examined for a range of dashboards.
