Abstract
PURPOSE: To perform distal display and bar-graph display having different resolutions, by setting a plurality of counting times for a microcomputer in an automobile meter panel.
CONSTITUTION: The signals from car-speed sensor 1 and distributer contact 2 are subjected to waveform shaping by 4 and 5 respectively and are input to microcomputer 6; and its output is latched by 7 and is fed to liquid crystal display element 9 via drive circuit 8. Element 9 consists of car-speed digital display unit 901, unit 902 to display the number of revolutions of the engine, and unit 903, which displays the car speed in bar-graph and also the number of revolutions in switching operation. Counting in different counting times is operated in time-division by computer 6.
