Abstract
A segmented transparent LCD is disclosed that includes a LC module that is substantially transparent to visible light. The segmented transparent LCD includes an array of spaced apart display segments supported by the LCD module. Each display segment is configured to display a segment of the display image. Each display segment includes a non-specular light-redirecting segment configured to provide localized backlight to the display segment when the ambient light is incident thereon. The segmented transparent LCD allows for a display image to be displayed and viewed while also allowing a viewer to see through one or more transparent regions that separate the display segments. Methods of displaying a display image using the segmented transparent LCD are also disclosed.

A method of manufacturing a segmented liquid crystal display (LCD) that employs ambient light for displaying a display image, comprising:
- obtaining an LCD display including a liquid crystal (LC) module and front and rear polarizers, the LCD display having a front side and a rear side;
- attaching a light-redirecting layer to a rear surface of the rear polarizer;
- attaching a protective film to a front surface of the front polarizer and a protective film to a rear surface of the light-redirecting layer;
- scoring the front and rear sides of the LCD display to form front and rear segments, the scoring on the front side extending though the front polarizer to a front side of the LC module and the scoring on the back side extending through the light-redirecting layer and the rear polarizer to a rear side of the LC module;
- and
- removing select ones of the front and rear segments to thereby form transparent spaces extending between remaining ones of the front and rear segments.
