1. A method for wireless power transmission in a television system, comprising the steps of:
- transmitting, by a first set of antennas of at least two RF antennas of a transmitter coupled to the television system, power RF waves that converge to form controlled constructive interference at a location of a receiver coupled to an electronic device, wherein the receiver is configured to capture RF energy from the controlled constructive interference and to power or charge the electronic device, and wherein the transmitter with the at least two RF antennas is an individual component or an integrated layer of the television system;
transmitting, by a second set of antennas of the at least two RF antennas of the transmitter, additional power RF waves that converge to form controlled destructive interference, the second set of antennas being distinct from the first set of antennas;
receiving, by a communication component of the transmitter, communications from the receiver, wherein the communications from the receiver comprise a communication signal indicating a location of the receiver relative to the transmitter, and wherein the transmitter is configured to transmit the power RF waves that converge at the location of the receiver based upon the communications from the receiver; and
rectifying, by a rectifier coupled to the receiver, AC voltage received from the at least two RF antennas into DC voltage for charging the electronic device.

Abstract
Disclosed here is a TV system with an integrated wireless power transmitter. The wireless power transmitter enables the TV system to provide a power source in the form of pockets of energy. A wireless power receiver may be coupled to the electrical devices to receive an electrical power source and transfer it to the electrical device. The receivers in the devices may capture energy from the pockets of energy formed by the wireless transmitter component in the TV system in order to power an electrical device.
