First Claim
Patent Images
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 edge bar, wherein the frontlight film is configured to direct light through 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 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)

25. A method of assembling a display module, comprising:
-
providing a substrate having a first and second surface, the substrate comprising a display array formed over said first surface and a light-guiding layer located over said second surface, wherein the light-guiding layer is located opposite the display array; positioning an edgebar relative to the substrate such that a first surface of the edgebar is positioned adjacent a side surface of the light-guiding layer; and providing a reflector over said first surface of the substrate such that the reflector retains the edgebar in place, the reflector comprising a first substantially planar portion overlying the edgebar and a second substantially planar portion displaced from the edgebar and adhered to an underlying layer. - View Dependent Claims (26, 27, 28)
