Applications

Simple meter visibility and low power consumption supporting battery operation

Applications: Electric Wheelchair

Background and Challenge

For electric wheelchairs supporting users' independent mobility, the control panel is crucial for checking driving modes and battery levels. However, outdoor use presented unique challenges.

Reduced visibility due to direct sunlight

In bright outdoor sunlight, critical information on the screen became difficult to read, leading to user anxiety and increased accident risk.

Simple display requiring instant readability

To grasp the situation instantly while moving, unnecessary information must be eliminated, requiring high contrast where only text and icons stand out clearly.

Efficient use of limited power

Being battery-powered, it was essential to minimize display power consumption while maintaining a bright, clear display outdoors.

Reasons for Selection

OLED's overwhelming contrast, unbeatable by direct sunlight

OLED (organic EL) is self-illuminating, ensuring text and icons stand out clearly even under strong outdoor light. Compared to LCD, it produces deeper blacks, excelling in instant readability.

High reliability and a clean aesthetic suitable for medical and welfare equipment

VFDs deliver the reliability cultivated over years of industrial standards, combined with an eye-friendly, premium-looking blue-green display that conveys the reassurance expected in welfare equipment.
