55‐3: Invited Paper: From Smallest AR Glasses to Mainstream Display Projection — Latest Advances of Visible LED and Laser Solutions

Solid state light sources for projection displays have shown tremendous progress over the recent years. Their application usage is ranging from low luminance near to eye projection for augmented reality glasses to mainstream projectors. This presentation will share some of the latest progresses for laser and LEDs for Near‐to‐eye (NTE) displays and will describe important design challenges such as package integration and power efficiency. Besides, High Current LEDs are further pushing the limits and bring LED based projection light engines on eye‐to‐eye brightness level with lamp & laser‐based systems ranging up to 5,000 ANSI lumens.
