Rotary Knob Displays
A knob with the display built in — used where the control and the readout have to be the same object the user turns.
Cost-optimised displays with decorative printing, custom backlight colours and high volumes at stable quality.
A knob with the display built in — used where the control and the readout have to be the same object the user turns.
We design the board, the driver and the interface, so the display arrives as a working subsystem instead of a part you still have to integrate.
Full-colour TFT modules with controller and backlight, for instruments that need graphics rather than digits.
Temperature, fan speed and filter status on a wall-mounted controller that is read from across the room.
A countdown that must be readable through the machine door, replacing a mechanical timer and digital tubes.
Volume, temperature and filter life on an appliance panel that gets splashed and cleaned regularly.
A rotary control with a segment display inside it: temperature, mode and status on a part the user turns every day.
PM2.5 value, fan speed and filter life on a module delivered ready for the appliance assembly line.
A rotary knob with an integrated segment display: speed, incline and heart-rate icons driven from a single compact module.
Battery percentage, input and output wattage on a display that has to survive outdoor temperature swings and constant sun exposure.
Case studies
A complete backlight unit — light guide, diffuser, reflector and LEDs — delivered as one part for the assembly line.
A lit icon interface behind a semi-transparent mirror surface: the display design and the mirror coating have to be agreed together.
A wide-viewing-angle blue STN display for a baby-care appliance, where the reading is checked from above while holding a bottle.
Temperature, mode and schedule on a wall controller that must look right in a living room and read from across it.
A light guide with the optical pattern designed for uniform brightness — no visible LED hot spots at any edge.
Room temperature, setpoint and schedule state on a wall thermostat expected to run for years.
