Connector of connecting light sensor and substrate and method of fabricating light sensor

摘要

A connector of connecting a light sensor and a substrate is utilized for rotating the light sensor so that the light-receiving direction of the light sensor is parallel with the substrate. When the connector is utilized in an optical touch system, the light sensor can be disposed on the substrate of the optical touch system by means of general manufacturing facilities of flat display panels. Meanwhile, the light-receiving direction of the light sensor is parallel with the substrate of the optical touch system.
