PACKAGING STRUCTURE OF AN OPTICAL MOTION SENSOR
First Claim
1. A packaging structure of an optical motion sensor, comprising:
- a packaging substrate;
an optical detection module provided on the packaging substrate and electrically connected with the packaging substrate, the optical detection module including at least one transverse line and at least one longitudinal line of complementary metal-oxide-semiconductor (CMOS) linear scanning modules; and
a packaging mask provided on the packaging substrate to package the optical detection module, the packaging mask being provided therein with a transparent body and a hole formed on the packaging mask.

Abstract
A packaging structure of an optical motion sensor includes a packaging substrate, an optical detection module, and a packaging mask. The optical detection module is provided on the packaging substrate and is electrically connected with the packaging substrate. The packaging mask is disposed on the packaging substrate to package the optical detection module. Further, the packaging mask is provided therein with a transparent body and a hole formed on the packaging mask. Via the above structure, light, passes through the transparent body inside the hole, and thus shines the optical detection module. In this way, the optical detection module is isolated from dirt in the air, thereby reducing possible damage or interference and reducing the volume of the packaging structure.
