Title: BACKLIGHT FOR SIGNAGE DISPLAY
Abstract:
Display devices (100) include a solid state-based light guide illumination device (101), one or more tertiary reflectors (170'), and a display panel (180´). The illumination device and tertiary reflectors provide a backlight for a display panel in the display device. Components of some of the disclosed displays are configured such that the one or two tertiary reflectors uniformly illuminate the rear of the display panel, so that all areas of the display panel have a uniform brightness when viewed by an observer, e.g., directly in front, and along an optical axis, of the display device. Moreover, components of some of the disclosed display devices are configured such that the rear of the display panel is uniformly illuminated regardless of whether the display panel receives the illumination from the illumination device directly, or from the one or two tertiary reflectors.
