Patent number: 10401721Abstract: Implementations described herein generally relate to the use of display screens. More specifically, implementations generally relate to a large format transmissive and self-emissive display screen where the display screen includes multiple screens coupled together using transparent adhesive tape. Implementations described herein minimize internal reflections visible to screen viewers when an edge of the adhesive layer is scanned by a beam spot produced by a scanning beam in a scanning beam system having multiple screens held together by the adhesive layer to form a seamless viewing screen. In some implementations, the internal reflections are minimized by applying the adhesive layer between horizontal and vertical seams between each screen of the multiple screens wherein the adhesive layer has non-straight edges so as to minimize the total surface area of the edge of the adhesive layer that falls within the beam spot produced by the scanning beam.Type: GrantFiled: February 19, 2015Date of Patent: September 3, 2019Assignee: PRYSM, INC.Inventors: David M. McAndrew, John L. Ritter

Patent number: 10303416Abstract: In one embodiment, the modular display includes aggregates of individual panel tiles arranged between two large plastic sheets. The footprint of the large plastic sheet sandwich becomes the dimension of the display screen. The tilettes are phosphor emission panels with a full complement of emittable pixels. By separating the tilettes from the final full dimension sheet, the tilettes can be manufactured in transportable sizes and the outer full dimension sheets can be rolled for easy transport to the final install location.Type: GrantFiled: October 4, 2016Date of Patent: May 28, 2019Assignee: PRYSM, INC.Inventors: Roger A. Hajjar, John L. Ritter, David Kindler, Jahja I. Trisnadi

Patent number: 10296041Abstract: The disclosure described herein generally relates to an image panel and a method of compressing the image panel. A breather assembly is coupled to at least one edge of the image panel and a vacuum is drawn through the breather assembly to pull the image panel portion and the front panel into intimate contact with phosphors sandwiched therebetween. The breather assembly draws the vacuum from the air pockets between adjacent phosphors to pull the image panel flat and thus prevent image artifacts from forming while also permitting the image panel portion and the front plane panel to move independently.Type: GrantFiled: May 23, 2017Date of Patent: May 21, 2019Assignee: PRYSM, INC.Inventor: John L. Ritter

Patent number: 9995997Abstract: A multi-layer display screen capable of being tiled without a visible gap between tiled screens and methods of using said device are described herein. In one embodiment, a system includes a light generator configured to produce light and a multi-layer screen with a plurality of layers. The multi-layer screen can be configured to permit the light from the light generator to propagate therethrough. The plurality of layers can include an opaque region layer having a plurality of opaque regions and a first layer comprising one or more abutted layers disposed within a common plane, the abutted layers spaced apart by a gap, wherein the gap is coincident with the opaque region.Type: GrantFiled: October 2, 2013Date of Patent: June 12, 2018Assignee: PRYSM, Inc.Inventors: Roger A. Hajjar, Philip J. Ralli, John L. Ritter

Publication number: 20110305000Abstract: A display screen having phosphor regions maximizes light leaving the phosphor regions using a gaseous, liquid or solid matter that is disposed between the light-producing phosphor regions and a divider member configured to separate the light-producing phosphor regions. The gaseous, liquid or solid matter may be air, a polymer, a gel, or other material that optically separates and has an index of refraction substantially less than the indices of refraction of the divider member and the light-producing phosphor regions.Type: ApplicationFiled: June 7, 2011Publication date: December 15, 2011Inventors: Sergey A. Bukesov, David Kindler, John L. Ritter
