Abstract

The invention described herein represents a significant advancement in electric display addressing and powering. A first display element comprising a first wireless transponder element is integrated with a first pixel element so as to controllably turn the pixel element on and off according to instructions received wirelessly from an RFID reader and in accordance with an image in a memory. The electronic display comprising a plurality of similar display elements in array each individually controlled wirelessly by an RFID reader dialog in accordance with an image in memory and a processor of the image in communication with the RFID reader.

Claims

1. An electronic display comprising;

a first transponder,

a first display pixel,

a plurality of transponders,

a plurality of pixels,

a wireless communication signal,

and wherein in response to said wireless communication signal, said first transponder causes said first display pixel to transition between a first visible state and a second visible state, and wherein the plurality of similar transponders individually control respective individual pixels in said plurality of pixels to individually transition between either of at least two visible states in response to the wireless communication signal, such that an image comprising a controlled pattern of pixels including some in the first visible state and some in the second visible state is displayed on the electronic display.
