OPTICAL NAVIGATION SENSOR DEVICE AND OPTICAL MODULE, A PORTABLE MOUSE USING THE SAME

摘要

Provided is an optical navigation sensor device. A semiconductor light source is integrated along with a plurality of unit light detection arrays. When light emitted from the semiconductor light source is reflected by an external surface, the light detection arrays sense motion by detecting the reflected light. When a module is manufactured using the optical navigation sensor device, its entire size is significantly reduced, such that a lightweight, thin, and compact module can be manufactured. An inexpensive module can be manufactured by process simplification.
