Abstract
A backlight includes a waveguide with a plurality of light emitting diodes positioned in cavities in the back surface in a center region of the waveguide. The back surface of the waveguide can be tapered from the center region to the edges so that the edges are thinner than the center region. Additionally, with the light emitting diodes in the center region of the waveguide, as opposed to along the edges, the bezel may be eliminated or at least minimized in height, e.g., 1 mm or less. Additionally, multiple waveguides may be used and configured in a 'V' shape to minimize the bezel.
