    • 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 according to a hysteresis of ±0.7 kilometer per hour as shown in FIG. 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 in FIG. 6(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 in FIG. 6(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.
    • 提供了即使在低温环境下也能够确保高可视性而不增加或扩大功耗的车用液晶显示装置。 根据如图7所示的±0.7千米/小时的滞后,显示车辆速度Ddis被切换。 如图6(b)所示,在不低于45℃的正常或高温环境下,相对于图11所示的车速变化。 6(a)。 也就是说,即使车速D在51.4公里和52.6公里之间变化,显示车速Ddis保持在52公里。 根据图1所示的±1.0千米/小时的滞后,显示车速Ddis被切换。 如图6(c)所示,在低于45℃的低温环境下,即使车速D在51.1公里和52.9公里之间变化,显示车速Ddis保持在52公里。
