Definitions

  • Various types of display such as near eye displays, require large aperture to cover the area where the observer’s (i.e., user’s, viewer’s) eye is located (commonly referred to as the eye-motion box - or EMB).
  • the image that is to be projected into the observer’s eye is generated by a small optical image generator (projector) having a small optical aperture.
  • Optical arrangements for displays may employ a light-guide optical element (LOE) to expand an input image in one or more dimensions.
  • LOE light-guide optical element
  • LOE reflective LOE
  • the LOE is implemented as a transparent substrate bounded by two parallel major external surfaces configured to support propagation of light therebetween via (total) internal reflection
  • the image expansion is performed by a set of mutually-parallel partially-reflecting internal surfaces (or “facets”) located between the major external surfaces.
  • facets mutually-parallel partially-reflecting internal surfaces
  • FIG. 1 illustrates a conventional stack 1 of transparent plates, showing parallel cutting planes 15 obliquely inclined to the plate faces.
  • the stack 1 is shown as being topped off (at the top and bottom) with additional transparent plates having a thickness of several times that of the other plates.
  • the layer of adhesive between the plates should be as thin as possible.
  • the compensation members have adjustable height, the height is measured along a dimension perpendicular to the parallel faces of the transparent plates.
  • FIG. 2 is a schematic representation of a staggered stack of parallel-faced transparent plates that can be cut along parallel cutting planes to produce one or more LOEs;
  • FIG. 8 is a schematic representation of an LOE, having a pair of mutually-parallel major external surfaces and a set of mutually-parallel partially-reflecting internal surfaces obliquely inclined relative to the major external surfaces, that may be fabricated from a staggered stack of plates that are bonded together according to embodiments of the present disclosure;

  • a second dimension that is perpendicular to the first dimension and is in a plane that is parallel to the plane of the faces of the plates (i.e., going in to / coming out of the drawing), there may be no offset (i.e., the plates may be aligned in the second dimension).
  • the staggering between adjacent plates may or may not be uniform.
  • each pair of laterally offset plates need not necessarily be offset by the same amount, and the number of plates in each group of aligned plates need not necessarily be the same.
  • the steps 14 may have uniform dimensions (uniform width and/or uniform height) across the steps, or variable dimensions (variable width and/or variable height) that differ from step to step.
  • the uniformity or variability of the step dimensions is a function of various parameters, including the dimensions of the thin plates 12 (and thick plates 12T and 12B), and the amount of lateral offset between pairs of adjacent plates and/or the number of aligned plates in a group.
  • optical coating is provided at one face (but in certain cases both faces) at each of the interfaces 17 between the thin plates 12.
  • the optical coating is an at least partially-reflecting coating that provides partially- reflecting optical properties. It is noted, however, that the methods according to the embodiments described herein may be used to produce other types of optical devices aside from LOEs, including optical elements having fully-reflecting internal surfaces. Therefore, other types of coating, such as fully-reflecting coating, can be provided at the interfaces 17 between the plates 12.
  • the stack 10 is placed (positioned) between oppositely disposed upper and lower pressing members 22 and 24, which are shown as being part of a press apparatus 20. As shown, the stack 10 is positioned in a space 26 between the pressing members 22 and 24. The stack 10 is placed so that the thin plate 12 toward the upper (top) part of the stack 10 is associated with the upper pressing member 22 and the thin plate 12 toward the lower (bottom) part of the stack 10 is associated with the lower pressing member 24.
  • This correspondence between the plate steps 14 and the stepped configuration 44 of the compensation members 42 allows contact surfaces of the compensation members 42 to contact (preferably at a direct abutment) the exposed parts of the parallel faces (and preferably also the edges) of the plates 12, 12T, 12B that form the steps 14, in particular when the press apparatus 20 is actuated (i.e., when the press members 22 and 24 apply pressure to the stack 10).
  • the complementary features between the plate steps 14 and the stepped configuration of the compensation members 42 promotes interlocking or mating between the compensation members 42 and the stack 10, which allows the compensation members 42 to interface smoothly with the offset portions of the plates 12, 12T, 12B, filling the voids created by the lateral offset(s), in particular when the press apparatus 20 is actuated.

  • the height differential (vertical direction in the figure) between adjacent compensation members corresponds to the heights of the steps 14, and the widths (horizontal direction in the figure) of the compensation members correspond to the widths of the steps 14.
  • This stepped configuration 44 allows the contact surfaces 43 of the compensation members 42, which are the exposed vertical and horizontal surfaces shown in FIG.
  • the press arrangement is preferably configured to apply pressure so that the pressure on the adhesive between the plates is in the range between approximately 0.2 MPa and 1 MPa.
  • This preferred pressure range results in squeezing out a substantial amount of adhesive (least 95%) from the interfaces between the plates so that suitably thin adhesive layers are achieved, while at the same not damaging (e.g., cracking or breaking) the plates.
  • pressing forces in the range between approximately 140 kilogramforce and 700 kilogram-force (for plates having interface dimension of approximately 70 mm by 100 mm) will achieve the requisite pressure needed to sufficiently thin the adhesive layers without damaging the plates.

  • some or all of the compensation members 42 may have adjustable height, measured along a dimension perpendicular to the parallel faces of the plates 12 of the stack. Adjustment of the height of a compensation member may provide further control of the pressure applied by the compensation member. Control of the height adjustment may be provided by an actuator 48, which may be a pneumatic actuator, hydraulic actuator, or any other suitable actuation mechanism.
  • each compensation member 42 is height-adjustable and has an associated actuator, implemented as a pneumatic drive piston. This enables pressure applied by each compensation member to be controlled independently.

  • FIG. 7 illustrates another embodiment in which a pair of insulating members 50 and 52 is deployed.
  • the insulating members 50 and 52 increase the uniformity of the pressure applied on each of the block members 34 and 36.
  • the upper insulating member 50 which may be implemented as a cushion, for example an air cushion, is deployed between the upper block member 34 and the upper pressing member 22.

Abstract

L'invention concerne des procédés d'assemblage de plaques transparentes à faces parallèles. Les plaques sont agencées en un empilement avec un décalage latéral entre une ou plusieurs paires de plaques adjacentes pour définir des étages de plaque. Un adhésif est disposé aux interfaces entre des plaques adjacentes de l'empilement, et un revêtement est disposé sur une face au niveau de chacune des interfaces. Dans un premier ensemble de procédés, l'empilement est placé entre une paire d'éléments de pression, et des éléments de compensation sont disposés dans une configuration étagée qui correspond aux étages de plaque. Une pression est ensuite appliquée aux plaques par l'intermédiaire des éléments de pression. Dans un autre ensemble de procédés, l'empilement est placé dans un récipient souple qui a une ouverture, et le gaz est extrait du récipient par l'intermédiaire de l'ouverture pour amener le récipient à se déformer autour de l'empilement, appliquant ainsi une pression sur les côtés de l'empilement et provoquant la redistribution de l'excès d'adhésif à partir des interfaces.
