Scientists have created pixels that can both emit and receive light simultaneously, eliminating the traditional tradeoff between display and sensor functions on a single surface. This advancement enables practical applications in AR devices, spatial computing, and interactive displays where real-time environmental sensing and image projection must occur in the same physical space without mechanical switching or dual-layer stacking. Today's AR glasses and autonomous systems require separate emitters and sensors, making them bulkier and more power-hungry. Combining these functions reduces component count and power consumption.
