Abstract

A display device including an illumination source disposed behind an at least partially translucent display area, with a diffuser baffle disposed therebetween. The diffuser baffle includes at least one diffuser lens with a gap on at least one side thereof. Light emitted by one or more light devices on the illumination source is dispersed and scattered by the diffuser lens and gap in the diffuser baffle before being projected on the back of the at least partially translucent display area. The dispersed and scattered light from behind more evenly illuminates the at least partially translucent display area.
