Microprocessor Control for Liquid Crystal Instrument Panel 820101

An LCD instrument panel, which displays a vehicle’s speed, an engine revolution, a fuel level and a coolant temperature, in digital or bargraph form on a single, large area LCD, has been developed. In adapting electronic items to the instrument panel, a single chip 8-bit microcomputer which manages most of the signal processing with excellent software techniques, a specially designed LCD driver IC and some hybrid-ICs have been employed. In this way, a minimised electronic assembly and a very suitable display were designed so that mass-production became possible.
