US Patent:

20180348621, Dec 6, 2018

Filed:

Aug 3, 2018

Appl. No.:

16/053903

Inventors:

- San Jose CA, US
Michael P. McMahon - Holden MA, US
Philip J. Ralli - Sudbury MA, US

International Classification:

G03B 21/56
H04N 9/31
G02B 5/20

Abstract:

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.
