Abstract
Systems, methods, and computer-readable media for transmitting data using invisible light via a display assembly of an electronic device are provided. This may enable more data to be transmitted simultaneously via a single display assembly of a limited size. For example, a single display assembly may simultaneously transmit a first type of data using visible light that may be comprehensible to a user (e.g., textual information that may be legible to a human) as well as a second type of data using invisible light that may be machine-readable (e.g., a barcode that may be detected by a scanner device but that may not be seen by a human).
