Abstract
A total internal reflection-based display may be driven by an apparatus and method to move electrophoretically mobile particles into and out of an evanescent wave region to create static and video images. The apparatus may comprise one or more of a host microprocessor/controller, display controller, TIR display panel, frame buffer memory 1, frame buffer memory 2, host interface, temperature/environmental sensor, timing controller, look up table, power management integrated circuit or display panel interface.

A method to display an image on a Total Internal Reflective (TIR) display, the method comprising:
- processing native image data to provide processed image data;
- storing a first portion of the processed image data at a first memory location and storing a second portion of the processed image data at a second memory location;
- receiving a first ambient signal, the first ambient signal representing an ambient display condition at a first time frame;
- selecting a first waveform and a first voltage to display the first portion of the processed image data as a function of the first ambient signal;
- receiving a second ambient signal, the second ambient signal representing an ambient display condition at a second time frame;
- selecting a second waveform and a second voltage to display the second portion of the processed image data as a function of the second ambient signal;
- and
- applying the second waveform and the second voltage to at least one of a first and second electrodes to move a plurality of electrophoretically mobile particles from the first electrode to the second electrode to absorb an incoming ray of light at an evanescent wave region formed proximal to the second electrode to thereby provide a dark state of the TIR display at the second electrode.
One or more non-transitory computer-readable media containing instructions that, when executed by one or more processors, causes a system that includes a Total Internal Reflective (TIR) display to perform one or more operations, the operations comprising:
- processing native image data to provide processed image data;
- storing a first portion of the processed image data at a first memory location and storing a second portion of the processed image data at a second memory location;
- receiving a first ambient signal, the first ambient signal representing an ambient display condition at a first time frame;
- selecting a first waveform and a first voltage to display the first portion of the processed image data as a function of the first ambient signal;
- receiving a second ambient signal, the second ambient signal representing an ambient display condition at a second time frame;
- and
- selecting a second waveform and a second voltage to display the second portion of the processed image data as a function of the second ambient signal;
- sending an instruction to apply the second waveform and the second voltage to at least one of a first and second electrodes to move a plurality of electrophoretically mobile particles from the first electrode to the second electrode to absorb an incoming ray of light at an evanescent wave region formed proximal to the second electrode to thereby provide a dark state of the TIR display at the second electrode.
