1. A display module, comprising:
- a light-transmissive substrate comprising a first surface and a second surface;
an edgebar in optical communication with a light source, wherein the edgebar is located over the first surface of the substrate;
a frontlight film adjacent the edgebar and in optical communication with the edgebar, wherein the frontlight film is located over the first surface of the light-transmissive substrate, and wherein the frontlight film is configured to direct light through the first surface of the light-transmissive substrate; and
a reflector, the reflector comprising a first substantially planar portion overlying the edgebar and a second substantially planar portion located over the first surface of the substrate and laterally displaced from the edgebar.

Abstract
In order to minimize the footprint of a display module, a frontlight system positioned over a first surface of a substrate may be used. The frontlight system may include an edgebar positioned over the first surface of a display substrate, and a Z-shaped reflector having a first planar portion overlying the edgebar and a second planar portion adhered to the first surface of the substrate or layers overlying the first surface of the substrate. Such a reflector may be located wholly within the footprint of the display substrate, minimizing the footprint of the display module.

21. An edgebar subassembly configured for use in a display module, the edgebar subassembly comprising:
-
an edgebar configured to receive light through a first surface and reflect light through a second surface orthogonal to said first surface; and a reflector configured to retain the edgebar, the reflector comprising; a first substantially planar portion configured to overlie the edgebar; and a second substantially planar portion configured to be adhered to an underlying layer, wherein the first substantially planar portion extends generally parallel to the second substantially planar portion; wherein a lower surface of the second substantially planar portion is substantially coplanar with a lower surface of the edgebar, and the edgebar is retained by the reflector. - View Dependent Claims (22, 23, 24)
