(54) Title: LIGHT EMITTING DIODE COMMUNICATION DEVICE, METHOD OF FORMING AND OPERATING THE SAME (57) : Various embodiments may relate to a light emitting diode (LED) communication device including a communication interface configured to cou- ple with an electronic device. The LED communication device may also include 0 101 0 an electrical interface electrically coupled to the communication interface. The LED communication device may further include a light emitting diode electri- cally coupled to the electrical interface. The electrical interface may be config- ured to convert data signals received from the electronic device into driving sig- nals transmitted to the light emitting diode during uplink, and to convert sensing signals received from the light emitting diode into data signals transmitted to the electronic device during downlink The light emitting diode may be configured to convert the driving signals received from the electrical interface into a plurali- ty of light pulses during uplink, and to convert a plurality of light pulses received by the light emitting diode into the sensing signals during downlink [Continued on next page] FIG.
