Abstract: A display system includes a display panel and a backlight disposed behind the display panel. The backlight has a light guide and at least one light source that directs light into an edge of the light guide. The light guide comprises a front layer facing the display panel, a back layer facing away from the display panel, and a plurality of connecting members connecting the front and back layers. The spaces formed between the connecting members and the upper and the first and second layers are referred to as flutes. Light from the light source may propagate along the flutes.

Abstract: An optical article has a substrate including a reflective polarizing element preferentially reflecting light having a first polarization state and preferentially transmitting light having a second polarization state and a beaded layer disposed on the substrate. The beaded layer includes transparent binder and a plurality of transparent beads dispersed therein. A normal angle gain of the optical article with the beaded layer is increased when compared to a normal angle gain of the same optical article but without the beaded layer.

Abstract: Photoresists are disclosed that display increased sensitivity, measured as lithographic potential, when compared to known photoresists that contain melamine resin as a crosslinker. The melamine resin in these photoresists contains a higher percent by weight of monomeric hexamethoxymethylmelamine than in known resists.
