Case study
LCD for an Ozone Sterilising Machine
A countdown that must be readable through the machine door, replacing a mechanical timer and digital tubes.
The requirement
The previous generation used a mechanical timer plus digital tubes. The new design needed a single display showing remaining time, cycle stage and safety status, readable through a tinted door.
What we supplied
- Segment layout with a dominant countdown field and a cycle-stage indicator
- High-contrast structure selected for reading through the door window
- Backlight for the cycle stages that run in a dark room
- Decorative printing to hide the inactive segments behind the window
Why it matters
Safety equipment has to be unambiguous: the user must be able to tell from a distance whether the cycle has finished and whether the door can be opened.
