  • DISPLAYING IMAGES ON TOTAL INTERNAL REFLECTIVE DISPLAYS
    Publication number: 20230359101
    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.
    Type: Application

  • DRIVING METHODS FOR TIR-BASED IMAGE DISPLAYS
    Publication number: 20230185153
    Abstract: Optical states in TIR-based image displays may be modulated by movement of electrophoretically mobile particles into and out of the evanescent wave region at the interface of a high refractive index convex protrusions and a low refractive index medium. The movement of particles into the evanescent wave region may frustrate TIR and form dark states at pixels. Movement of particles out of the evanescent wave region may allow for TIR of incident light to form bright states at pixels. The movement of the particles may be controlled by employing the drive methods of pulse width modulation, voltage modulation or a combination thereof.
