75-1: Invited Paper: GaN-based Emissive Microdisplays: A Very Promising Technology for Compact, Ultra-high Brightness Display Systems

High-brightness GaN-based emissive microdisplays can be fabricated with different approaches. Using the hybridization approach, we have developed 2 types of GaN microdisplay prototypes with a pixel pitch of 10 μm: passive-matrix, 300 x 252 pixels and active-matrix, 873 x 500 pixels. Brightness as high as 1 x 106 and 1 x 107 Cd/m2 for blue and green arrays, respectively were reached. This technology is suitable for augmented reality systems or Head-Up Displays
