Wouldn't the display link be high latency though?

This patent is crazy. It is an attempt to own a generic concept with no particular hardware design or methods. I could just as well patent a rocket that can fly to the stars.

If you want to transmit enough power to "light" the screen as in drive either a backlight or OLED, your wireless power station would need to pump out some rather serious power... if you want 100mW to reach the device, you will likely need to transmit over 10W due to spatial dispersion. Imagine what people who are worried about WiFi's ~100mW would say about that.

Wireless power is extremely inefficient without use of tightly collimated beams... and tightly collimated beams would be much less convenient than cables due to the need for lined-up directional antennas.

In addition to people's fear of that much power being pumped wirelessly, the whole thing seems rather impractical.
