Abstract
A solid-state display apparatus for visually indicating the status of vehicle speed, engine speed, fuel remaining, coolant temperature and other parameters which altogether represent the condition of the vehicle includes solid-state display gauges constituted by either electro-luminescent elements or liquid crystal display cells. Some of the parameters are constantly displayed through their own display gauges at all times during the use of the vehicle while other parameters are adapted to be displayed upon demand through their own display gauges. The other parameters can also be automatically and forcibly displayed in the event of the occurrence of an out-of-limits value thereof.
