Diffrative waveguides for AR developer WaveOptics (owned by Snap) announced a strategic supply partnership with Jade Bird Display (JBD) for MicroLED microdisplays. JBD will supply its 0.13-inch VGA microdisplays to WaveOptics, to be incorporated into the company's Leopard development kit.

The Leopard AR reference kit has a form-factor similar to traditional consumer eyewear available, with a single projector (right-side only), providing a monochrome (green) image. The Leopard uses WaveOptics’ ‘Katana’ waveguide platform, its thinnest and lightest waveguide at 1.15 mm thick and 7 grams. The light engine, called Loki, is designed by WaveOptics with the JBD microLEDs and weighs 6 grams and has a volume of 760 mm³.

VueReal announced that it has has received volume orders for its transparent displays from automotive and aerospace customers. The company is producing custom displays at its pilot production line in Canada.

Back in June VueReal demonstrated its first transparent microLED display. The display is between 3 and 4 inches in size, with high brightness (over 3,000 nits) and very high transparency (85%). Vuereal says that its microLED cartridge- and printing- based production process enables the production of custom displays with high yield and high throughput.
