Methods for making display

A method for forming a display, the method comprising the steps of:

• providing a slurry comprising a plurality of imaging elements in a fluid each imaging element being adapted to cause a radiation sensor to sample radiation and to transmit a wireless signal indicating the amount of radiation in the sample and with each imaging element further being adapted to receive a wireless signal having an illumination value therein and to generate a control signal causing an illumination element to generate light at an intensity that is determined based upon the control signal;
• said plurality being adequate in number for sampling an irradiance pattern with sufficient resolution to allow a discernable image to be assembled based upon the samples;
• using said slurry to provide a plurality of individual imaging elements across an image capture area of a surface;
• and
• associating each imaging element with location information so that signals from each imaging element can be assembled to form an image of the light that is incident upon the imaging element.

A method for forming a surface comprising an array of spaced-apart imaging elements, the method comprising the steps of:

• providing a surface comprising a plurality of cavities;
• providing a slurry comprising a plurality of imaging elements in a dispersing liquid;
• and
• dispensing said slurry over said substrate to deposit, so that imaging elements are distributed into individual ones of said plurality of cavities, individual said imaging elements.

A method for assigning positional coordinates to an imaging element in a grouping of imaging elements comprising the steps of:

• identifying a first reference imaging element at a first coordinate reference point, a second reference imaging element at a second coordinate reference point, and a third reference imaging element at a third coordinate reference point;
• prompting another imaging element to emit at least one locator signal;
• receiving said locator signal and locator signals from at least each of said first, second, and third reference imaging elements;
• and
• applying a triangulation calculation to identify the positional coordinates of the imaging element relative to said first, second, and third coordinate reference points.
