Abstract:
A light source and a method for constructing a light source for a display device are provided. A first member having first and second sides and an opening therethrough is provided. A seal is positioned on the first side of the first member and on at least one side of the opening, the seal having a first thickness. A second member is positioned on the first side of the first member such that the seal is between the first and second members. A light emitting diode (LED) operable to emit light is positioned at least one of partially between the first and second members and partially within the opening. The first member is secured relative to the second member causing a force to be applied to the seal such that the thickness of the seal is reduced to a second thickness and substantially no light can propagate between the seal and the first and second members.
