SMK Develops the Industry’s Smallest* Device
Allowing Rotary Input Operation on Touch Panel

   SMK has developed the “Jog Dial on Touch Panel”, an input device that can be placed and operated on a touch panel, in response to the recent trend toward larger in-vehicle displays and increasingly multifunctional home appliances.
   This is a new concept input device that allows users to physically turn the dial switch on the touch panel in addition to the usual operation of touching the screen, which was achieved by combining SMK’s touch sensor technology with mechanical design technology. It covers a wide range of applications, including volume, air conditioning, timers, and menu selections.
   Placing the dial switch on the touch panel saves space and improves the design flexibility of the final product, contributing to the creation of new designs.
   The minimum size is φ30 mm. It is the smallest in the industry as a capacitive-type jog dial.
   SMK will continue to develop high-value-added products to meet the demands of an increasingly diverse and sophisticated display market.

* According to SMK's research.

Infotainment systems (in-vehicle infotainment, display audio, car navigation equipment, etc.), automotive center consoles,
and home appliances with input devices (washing machines, refrigerators, microwave oven, etc.)
