Wirelessly powered display and system

A wirelessly coupled display system, comprising:

• a device comprising a wireless power transmitter that provides wireless power within a specified range;
• and
• one or more wirelessly powered displays located within the specified range and responsive to the wireless power provided by the device to display an image, wherein each wirelessly powered display comprises:
• a substrate;
• an antenna with multiple turns disposed on the substrate;
• an electronic circuit disposed on the substrate;
• and
• one or more pixels each having one or more inorganic light-emitting diodes disposed on the substrate;
• wherein:
• the electronic circuit is electrically connected to the one or more inorganic LEDs and the antenna;
• the antenna is responsive to electromagnetic energy from the device to provide electrical power;
• and
• the electronic circuit comprises a power converter that converts a signal with a relatively high current and low voltage to a signal with a relatively high voltage and low current.

A wirelessly powered display, comprising:

• a substrate;
• and
• a plurality of light-emitting modules disposed on the substrate, each light-emitting module having an antenna with multiple turns disposed on the substrate, an electronic circuit disposed on the substrate, and one or more pixels each having one or more inorganic light-emitting diodes disposed on the substrate;
• wherein, for each light-emitting module, the electronic circuit is electrically connected to the one or more inorganic LEDs and the antenna, the antenna is responsive to electromagnetic energy from a device comprising a wireless power transmitter within a specified range to provide electrical power to the wirelessly powered display, and the electronic circuit comprises a power converter that converts a signal with a relatively high current and low voltage to a signal with a relatively high voltage and low current.
