Abstract

A system for and method of illuminating a contact (or touch) device such as a fingerprint sensor are disclosed. In an exemplary system, a touch sensor system has a surface or contact area and comprises a substantially transparent molding positioned over the contact area and a dynamic illuminator positioned to show through the molding. The dynamic illuminator is for indicating a status of the touch sensor system, such as power on, standby, error, low power, an input mode for receiving user input, or a selected operating mode. The touch sensor system includes any one of a fingerprint sensor, a miniature joystick, a touch-sensitive navigation disc, a touch-sensing navigation pad, an N-way pressure-sensitive directional control, to name a few touch sensor devices. In one embodiment, when the touch sensor comprises a fingerprint sensor, the operating mode is for emulating an input device such as a scroll wheel, a push button, a steering wheel, a joy stick, a pressure button, and a mouse. The operating mode also includes an authentication mode for authenticating an identity of a user. Preferably, the dynamic illuminator includes light sources and multiple light channels, colored or not, that are configured to be illuminated in multiple configurations, where each configuration corresponds to a status of the touch sensor system.
