SYSTEMS AND METHODS FOR IMPROVING A BUTTON ASSEMBLY

摘要

A button assembly is described. The button assembly includes a light emitting device that emits light. The button assembly further includes a lens cap that protects the light emitting device from being damaged. The lens cap has a top surface, a first cap side, a second cap side, a third cap side, and a fourth cap side. The second cap side connected to the first cap side, the third cap side connected to the second cap side, and the fourth cap side connected to the first cap side and the third cap side to form a plane. A first perpendicular distance between the plane and a first point on the top surface is different than a second perpendicular distance between the plane and a second point on the top surface. Additionally, a system for increasing life of a pixel is described.
