Document Type and Number:
Japanese Patent JP3193523
Kind Code:
B2
Abstract:
PURPOSE: To prevent an LCD display unit mounted on a moving terminal device, which is used for the warehousing and delivery control system of the refrigerated warehouse and carried in and out of the warehouse in a short time, from becoming hard to see.
CONSTITUTION: The display unit 11 which constitutes part of the moving terminal device is provided with a transparent heater 32 between a display part 31 (LCD display panel) inside a transparent plate 35, provided at an opening part 11b for viewing the LCD display panel and the transparent plate 35, and this transparent heater prevents dew condensation on the transparent plate 35 and variation in display characteristics with the temperature of the LCD display part. Further, the LCD display panel is provided with a temperature sensor 34 and a voltage applied to the LCD display panel is adjusted on the basis of the detected value of the temperature sensor 34 to cancel characteristic variation due to temperature variation by an electrode voltage.
