MULTILAYERED SCREENS FOR SCANNING BEAM DISPLAY SYSTEMS

摘要

A display screen includes a filter layer, a fluorescent layer having parallel fluorescent stripes, and an attachment layer between an excitation side of the fluorescent layer and a first side of the filter layer to attach the excitation side of fluorescent layer to the filter layer while providing vertical separation therebetween. The attachment layer includes attachment regions that are separated from each other by lateral spacings such that excitation-side air gaps are formed between areas of the fluorescent layer and the filter layer that correspond to the lateral spacings. During display operation, excitation light received on a second side of the filter layer propagates through to the first side of the filter layer, and at least a portion of the excitation light that propagates from the second side of the filter layer travels through the excitation-side air gaps to excite the fluorescent stripes.

主权项

1. A display screen comprising:
a filter layer having a first side and an opposing second side; a fluorescent layer including a plurality of parallel fluorescent stripes; and an attachment layer positioned between an excitation side of the fluorescent layer and the first side of the filter layer that attaches the excitation side of fluorescent layer to the filter layer while providing vertical separation between the fluorescent layer and the filter layer, the attachment layer including a plurality of attachment regions that are separated from each other by one or more lateral spacings such that one or more excitation-side air gaps are formed between areas of the fluorescent layer and the filter layer with the one or more excitation-side air gaps extending to excitation side surfaces of the fluorescent stripes, wherein, during display operation, excitation light received on the second side of the filter layer propagates through to the first side of the filter layer, and at least a portion of the excitation light that propagates from the second side of the filter layer travels through the one or more excitation-side air gaps to excite the fluorescent stripes.
