Light angle detection device, method for fabrication thereof and electronic device employing same

摘要

A light angle detection device according to an embodiment of the present invention includes a first light receiving lens, a first light sensing element, a second light receiving lens, and a second light sensing element. The first and second light receiving lenses and the first and second light sensing elements are disposed such that a first straight line passing through the center of the light receiving surface of the first light sensing element and the vertex of the first light receiving lens, a second straight line passing through the center of the light receiving surface of the second light sensing element and the vertex of the second light receiving lens, and a third straight line passing through the center of the light receiving surface of the first light sensing element and the center of the light receiving surface of the second light sensing element form an isosceles triangle.
