A LCD illuminator (20), when energized, emits light which impinges upon an input surface of a light pipe included in a LCD module (54). The LCD illuminator (20) includes a thermally-conductive housing (22) to which a thin, thermally conductive printed circuit board (“PCB”) (32) is mechanically and thermally bonded. The PCB (32) has an array of LED die (34) mounted thereon that face away from the thermally conductive housing (22). A layer of thermal interface material (56) interposed between an outer surface of the thermally conductive housing (22) and the LCD module (54) facilitates conducting heat generated by the LED die (34) out of the LCD module (54). Also disclosed is an improved LCD module (54) that includes the disclosed LCD illuminator (22).
