LIQUID CRYSTAL DISPLAY DEVICE, MOTORCYCLE INCLUDING SAME, AND METHOD OF USING SAME

摘要

A liquid crystal display device of a motorcycle is configured and arranged to rapidly warm up a liquid crystal panel at cool temperatures, without requiring an additional heating member. The liquid crystal display device includes a control unit, for controlling a liquid crystal panel, and a backlight. When the temperature of liquid crystal is lower than a predetermined value, or when it is within a fixed time period after turning on an ignition switch, as a warm-up period, the control unit increases power supplied to the backlight to a larger amount than that in a normal display state, to increase the amount of back light, and temporarily changes the entire display surface to a darker color, in order to increase the amount of light absorbed by the liquid crystal panel, simultaneously reducing the amount of light penetrating the display surface, and thereby speeding up warming of the liquid crystal panel.

主权项

1. A liquid crystal display device comprising:
a liquid crystal panel; a backlight source arranged on the rear side of a display surface of the liquid crystal panel, a display device control unit for controlling a display state of said liquid crystal panel; wherein said liquid crystal panel has
a warm-up configuration for increasing the temperature of the liquid crystal panel when a temperature of said liquid crystal panel is lower than a predetermined value, or when a time period after starting operation of said liquid crystal panel is less than or equal to predetermined time period, anda normal configuration for performing normal operation after completion of a warm-up period; and wherein said display device control unit is operable to switch between said warm-up configuration and said normal configuration, and during said warm-up configuration, said display device control unit adjusts display contents on said display surface such that an amount of light penetrating said liquid crystal panel becomes smaller than that in said normal configuration, as well as increasing output of said backlight source to a larger amount than that in said normal configuration.
