BACKLIGHT FOR DISPLAY UNIT WITH IMPROVED FILTERING, AND METHOD FOR CONSTRUCTING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a backlight for a display unit with improved filtering.

SOLUTION: A light source for a display unit and a method for constructing the light source are provided. A first member having first and second sides and a run-through opening is provided. A seal having a first thickness is positioned on the first side of the first member and on at least one side of the opening. A second member is positioned on the first side of the first member such that the seal is located 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 fixed 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.
