Abstract
Backlighting devices and methods for supporting and illuminating a display panel are disclosed. A display retainer and backlight device in accordance with an illustrative embodiment of the present invention may comprise one or more light pipes operatively coupled to a retainer housing that supports and illuminates an attached display panel. The retainer housing includes an optical waveguide that receives light collected by the one or more light pipes. A light scattering element and reflector may be employed to disperse and reflect the light rays to illuminate the backside of the display panel. A slot extending through a portion of the retainer housing may be configured to tightly receive an elastomeric zebra-strip, which electrically connects the circuit board to the display panel. A clip, tab or other fastening mechanism may be used to secure the retainer housing and display panel to the circuit board.
