A housing having a generally rectangular cross section includes apertured front and lower portions which are respectively adapted to receive a liquid crystal display (LCD) and a plurality of light emitting diodes (LEDs) and which are oriented so as to face generally transversely relative to one another. Disposed within the housing between its front and lower portions are facing convex and concave inner walls which form a light channel between the LEDs and LCDs. With the LCDs and LEDs respectively positioned within the apertured front and lower portions of the housing and mounted thereto, the facing inner walls of the housing direct light from the LEDs onto the aft, inner surface of the LCDs in a diffuse, uniform manner which provides backlighting for the LCDs and prevents direct viewing of the LEDs from in front of the LCDs thus eliminating LED hot spots. The housing is comprised of two plastic sections adapted for secure snap-acting engagement and is provided with a semi-rough interior surface for diffuse reflection of the LED-emitted light.

A video display arrangement comprising: a generally planar LCD display having an aft surface, a forward viewed surface, and a plurality of peripheral edges; at least one LED; and a hollow housing having an empty aperture extending therethrough and including an open forward section whereon is positioned said LCD display, an aft section for receiving said at least one LED, and a curvilinear intermediate section coupling said forward section to said aft section, wherein said at least one LED is positioned aft of and beyond a peripheral edge of said LDC display in an off-set manner and in non-alignment therewith such that light emitted by said at least one LED is transmitted through said empty aperture and is reflected by the curvilinear intermediate section of said housing onto the aft surface of said LCD display in providing backlighting therefor, wherein said housing includes first and second facing lateral panels and facing concave and convex panels coupled at respective adjacent ends to said first and second facing lateral panels so as to define said empty aperture.
