Abstract

Claims (40)

1. An electronic display device, comprising:

a light module;

a rollable screen that includes a plurality of pixels, each pixel comprising one or more fluorescent materials configured to emit visible light when excited by pulsed excitation radiation generated by the light module, wherein the excitation radiation originates from outside the screen;

reference marks disposed on an excitation side of the rollable screen and configured to reflect a servo beam away from the rollable screen as servo feedback light;

wherein the electronic display device includes one or more radiation servo beam detectors, which detect the reflected servo beam and direct servo detection signals to a display processor for processing;

wherein the one or more radiation servo beam detectors are proximate to the light module; and

wherein the rollable screen also has a viewer side with a viewing surface for viewing by a viewer opposite the excitation side, and wherein the viewer side and the excitation side are separated by the plurality of pixels.

2. The electronic display device of claim 1 , further comprising a roller mechanism mechanically coupled to an edge of the rollable screen and configured as a stowing mechanism for the rollable screen.
