Abstract
Disclosed embodiments provide an LED package and electronic display. An LED package can include an LED that emits red, green, blue and IR (infrared), where the IR portion is configured as either an emitter or (reversed biased) as a receiver. An electronic display includes multiple LED packages with the IR portions configured in a combination of transmitters and receivers. Thus, disclosed embodiments enable electronic displays that can serve as interactive video walls and floors that present a high-definition image along with interactive capabilities. Thus, disclosed embodiments serve to reduce cost and complexity in manufacture and deployment of such displays.
