Image forming displays is provided. The display has a first layer having imaging elements positioned thereon; and a power circuit to provide electrical energy for the imaging elements. Wherein each imaging element comprises: an illumination circuit having an illumination element adapted so that the illumination element generates light at an intensity that is based upon a control signal, and a wireless communication circuit adapted to detect a wireless communication signal and to generate the control signal. A body contains the wireless communication circuit and the illumination circuit with the body occupying a space that is less than about five cubic millimeters. Imaging elements can also be adapted to sense radiation and provide wireless signals having data therein said data being based upon the amount of sensed radiation.
