VEHICLE-USE LIQUID CRYSTAL DISPLAY DEVICE

摘要

A VEHICLE-USE LIQUID CRYSTAL DISPLAY DEVICE WHICH IS CAPABLE OF SECURING HIGH VISIBILITY EVEN UNDER A LOW TEMPERATURE ENVIRONMENT WITHOUT INCREASING OR ENLARGING POWER CONSUMPTION IS PROVIDED.@A DISPLAY VEHICLE SPEED DDIS IS SWITCHED ACCORING TO A HYSTERESIS OF ±0.7 KILOMETER PER HOUR AS SHOWN IN 6(B) UNDER A NORMAL OR HIGH TEMPERATURE ENVIRONMENT OF NOT LESS THAN 45°C WITH RESPECT TO A CHANGE IN A VEHICLE SPEED SHOWN IN6(A). NAMELY, EVEN IF THE VEHICLE SPEED D CHANGES BETWEEN 51.4 KILOMETERS AND 52.6 KILOMETERS, THE DISPLAY VEHICLE SPEED DDIS IS HELD AT 52 KILOMETERS. THE DISPLAY VEHICLE SPEED DDIS IS SWITCHED ACCORDING TO A HYSTERESIS OF ± 1.0 KILOMETER PER HOUR AS SHOWN IN6 (C) UNDER A LOW TEMPERATURE ENVIRONMENT OF LESS THAN 45°C. NAMELY, EVEN IF THE VEHICLE SPEED D CHANGES BETWEEN 51.1 KILOMETERS AND 52.9 KILOMETERS, THE DISPLAY VEHICLE SPEED DDIS IS HELD AT 52 KILOMETERS.
