Patent attributes
Systems and methods for transmitting information in interactive display systems are provided. In one example, an interactive display system comprises an interactive display including an electrode matrix having row and column electrodes, the row electrodes being sequentially driven, a display-side radio transceiver, and an input device including an electrode tip and an input device-side radio transceiver. The interactive display is configured to transmit a channel identifier in an electrostatic link formed between the electrode matrix of the display and the electrode tip of the input device, and the input device is configured to detect a position signal indicating a nearest row electrode in the electrode matrix adjacent which the electrode tip is positioned, and to transmit data indicating the nearest row electrode to the interactive display via a radio link between the input device side transceiver and the display side transceiver on a channel identified by the channel identifier.
