Abstract

A spacer (8a, 8b, 8c, 8d) for holding a first printed circuit board (PCB) (7a) in registration with a second PCB (7b) is disclosed along with a housing (10a, 10b, 10c, 10d) for a display assembly made up from a plurality of PCBs held in registration with each other using the clips, and a cover (30a, 30b, 30c, 30d) for LEDs mounted on the PCBS for improving the contrast ratio of the display assembly.
