Background and Challenge
Special transport vehicles operating in logistics environments must function under harsher conditions than standard industrial equipment. Display units, particularly those facing extreme temperature fluctuations from alternating use between cold storage and outdoor environments, faced the following challenges:
Reduced display responsiveness below freezing
Standard LCD displays suffered from slowed liquid crystal molecule movement in low temperatures like cold storage, causing delayed display changes or failure to illuminate.
High visibility outdoors and in dim warehouses
Operators needed to instantly read battery levels and other information without changing posture, both during daytime and in dimly lit warehouses.
Long product lifecycle
Special transport vehicles undergo repeated maintenance over extended periods. Components with supply discontinuation within a few years could not be used, making securing maintenance parts a significant burden.
Reasons for Selection
Unmatched “High-Speed Response” Even at -40°C
Unlike LCDs, VFDs use a vacuum tube structure, maintaining response speed even in extreme cold. This enables clear display immediately after power-up, even inside refrigerated warehouses.
High-Contrast Display Readable from Any Angle
Self-illuminating technology provides high visibility and a wide viewing angle. This ensures easy readability across diverse environments, from outdoors to warehouses, supporting safe operator control.
Long-Term Stable Supply Supporting Industrial Equipment
Unlike consumer products, production discontinuation (discontinuation) does not occur in the short term, ensuring continuous supply of the same specifications over the long term. This supports the long-term maintenance and operation of equipment.
