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.
