Patent ID: 7674000

Claim:
A method for constructing a light source for a display device comprising: providing a first member having first and second sides and a first plurality of openings and a second plurality of openings therethrough; positioning a plurality of seals on the first side of the first member such that first and second portions of each of the seals are on respective opposing sides of a respective one of the first plurality of openings, the plurality of seals having a first thickness; positioning a second member on the first side of the first member such that the plurality of seals are between the first and second members; positioning a first plurality of light emitting diode (LEDs) operable to emit light at least partially between the first and second members such that each of the first plurality of LEDs is at least partially between the first and second portions of a respective one of the seals and the light emitted therefrom is directed through the respective first opening; positioning a second plurality of LEDs operable to emit light at least partially between the first and second members such that none of the second plurality of LEDs is at least partially between the first and second portions of one of the seals and the light emitted therefrom is directed through a respective one of the second plurality of openings; and securing the first member relative to the second member, said securing causing a force to be applied to the plurality of seals such that the thickness of the seals is reduced to a second thickness and substantially no light can propagate between each of the plurality of seals and the first and second members, wherein each seal circumscribes each of only the first plurality of LEDs and none of the seals circumscribe any of the second plurality of LEDs.
