In one implementation, the package body and the optical lens collectively include at least one protrusion and concave, where the protrusion is aligned with the concave so that the optical lens mates with the package body, thereby causing the optical lens to self align with the package body. In another implementation, a protruding inner portion of the upper surface of the package body mates with the hollow dome structure, achieving a similar purpose. Consequently, generation of an eccentric fault between the optical lens and the package body is prevented.Type: GrantFiled: December 16, 2013Date of Patent: February 24, 2015Assignee: LG Display Co., Ltd.Inventors: Myung Soo Han, Seung Ho Jang, Won Seok Choi
