An illumination source is coupled to a partially transparent circuit board and is configured to emit light onto a compound mirror. The compound mirror is farther from an exit pupil of the HMD than the display and reflects light from the illumination source back towards the exit pupil of the HMD. Light reflected by the compound mirror is transmitted through the partially transparent circuit board onto the display, illuminating the display."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transparent and reflective illumination source","description":"A head-mounted display (HMD) includes a display illuminated by one or more illumination sources.
