Abstract
Fluorescent screens and display systems and devices based on such screens using at least one excitation optical beam to excite one or more fluorescent materials on a screen which emit light to form images. The fluorescent materials may include phosphor materials and non-phosphor materials such as quantum dots. A screen may include a multi-layer dichroic layer. Vector scanner systems may be constructed using screens with one or more fluorescent materials.
Claims12
A laser vector scanner system, comprising:
- at least one laser to produce an excitation laser beam;
- a two-dimensional scanner to scan the excitation laser beam to trace out a pattern;
- a display screen comprising a fluorescent layer that absorbs the excitation laser beam to emit visible light at a wavelength shorter than the excitation laser beam to represent the pattern.
A method, comprising:
- providing a screen having at least one fluorescent material which absorbs excitation light and emits visible colored light at a wavelength different from the excitation light;
- and
- scanning a beam of the excitation light on the screen to trace out a pattern and produce visible colored light which also traces out the pattern.
