摘要: An optical module includes a point light source device and an lens. The generates light. lens inner curved surface outer surface. has first roughly ellipsoidal shape having major axis minor that is substantially perpendicular to the axis. second generated by enters through exits from Therefore, number of modules used in display may be reduced lower manufacturing cost thereof.
