Light directing construction having corrosion resistant feature |
摘要 |
The present invention is a light directing construction for use in a display apparatus. The light directing construction includes a light directing film that has a prismatic structure having two sides, where one side includes saw tooth formations having tilted surfaces, and a metal coating on the side of the prismatic substrate having the saw-tooth formations. A corrosion-resistant feature is provided on the light directing construction to minimize the effects of corrosion experienced in salt atmospheres. In a first embodiment of the invention, the light directing construction includes an intermediate layer positioned between the light directing film and the metal coating. In a second embodiment of the invention, a peripheral polymeric coating is provided on the light directing constriction. This peripheral coating can be formed with a laser.
