- connection mechanism Further complicating the search for a viable connection mechanism is the desire for reduced device thickness to improve user comfort when the device is in use or being transported.
- the process of insert molding includes placing a stiff metal insert into an injection molding tool and then molding plastic features around the metal part.
- the plastic should be well integrated in the original metal part.
- mold quality permitting pieces of glass or different transparent material to be used as the “insert” such that complex three-dimensional plastic geometry may be integrated with a sheet of transparent material.
- the transparent cover lens over the display In a portable device, it is desirable for the transparent cover lens over the display to be integrated with overmolded plastic features, but this disadvantageously creates limitations as to the potential geometry for the glass or transparent insert.
- the transparent cover lens Over the viewing area of the display, one desires the transparent cover lens to be substantially thin and flat to result in an undistorted image and a small size for the finished device. Additionally, one desires that this cover lens also be as narrow and short as possible so that the resulting device is a minimal size.
- the glass or transparent insert mold process prefers a large amount of material beyond the display to improve the bond between plastic and glass or different transparent material and ensure that the overmolded plastic does not detach from the transparent insert in the finished product.

- the embodiments described herein can minimize device thickness, since a screw head, when using screws, can increase the device width by the head thickness, and can enhance reliability over snaps, which can loosen over time, have limited directional constraints, and can disengage upon mechanical shock. They can allow excellent serviceability over heat stakes that also require clearance for heat stake heads and avoid the need for special equipment and design efforts. Finally, they also allow excellent serviceability over glue and do not require the special equipment or complex process control that glue requires. These embodiments have great mechanical reliability and allow creation of robust attachment features over 3D formed glass or other transparent material, and have higher mechanical strength and less likelihood of scratching over the viewing area of the display over clear plastic housings.
- plastic details can be integrated directly onto the transparent material. This allows the transparent cover lens to be sized smaller than the display, but use the plastic overmold to keep the display edges protected during manufacturing and in the finished device.
- the process is capable of producing a smaller, more reliable portable device.
- a transparent lens and differing plastic material housing include a transparent lens including a front surface, a rear surface, and a perimeter edge, the perimeter edge including a flange, a plastic housing affixed to the perimeter edge flange having a different material than the transparent lens, a portion that is tangent to the front surface of the transparent lens, and a portion that is tangent to the rear surface of the transparent lens.
- the transparent lens can be made of glass or can be made of a durable transparent plastic material that differs from the material of the side walls to which it is attached. As described herein, when the transparent lens is made of plastic, it is to be understood that this constitutes a different material than the plastic used in the side walls.
- a display housing assembly has a transparent portion and a plastic portion, and includes a transparent lens having a front surface, rear surface, and perimeter edge.
- the perimeter edge includes a flange.
- a plastic side wall of the plastic portion is affixed to the flange.
- the plastic sidewall has a front surface portion that is co-planar with the front surface of the transparent lens; and a rear surface portion that is co-planar with the rear surface of the transparent lens. This configuration forms front and rear planar surfaces, each of which has both transparent material and plastic.
- the assembly further including a display that is affixed to the rear planar surface using a display adhesive.
- a device housing assembly has a display module including a front pane that may be transparent and a rear pane that may be transparent, the rear pane having a section longer than the front pane in at least one direction.
- the housing assembly further has a transparent lens and plastic housing, the transparent lens having a front and rear surface; and an adhesive between the front pane and the rear surface of the transparent lens.
- the housing includes a support structure molded to the rear surface of the transparent lens positioned proximally to the longer section of the rear pane and adjacent to the front pane, the structure providing mechanical support for the rear pane.
- Another embodiment of the disclosure is a thin cosmetic housing having dovetail features that assemble in a linear direction to an internal structural housing.
- the housing has cutouts to accept the dovetail features, thus constraining the cosmetic and structural housings in two axes.
- a pin is inserted through a hole in each dovetail perpendicular to the direction of dovetail assembly and into a hole in the structural housing. These pins constrain the cosmetic and structural housings in the third and final axis. Finally, a second thin cosmetic housing is snapped into snap holes on each dovetail of the first cosmetic housing which engage in the direction of the third axis. This housing fully covers the pins inserted previously which results in a better appearance of the finished device and prevents the pins from backing out far enough to disengage should they loosen over time. The attachment system results in a reduced width and thickness of the finished device
- the housing comprises a first housing component with a plurality of dovetail protrusions, at least one dovetail protrusion of the plurality having a first pin hole through a thickness of the protrusion, and a second housing component with a plurality of matching dovetail cuts, at least one dovetail cut containing a second pin hole.
- the housing further has a plurality of pins.
- the first housing component is mated in a linear direction with the second housing component with each dovetail protrusion aligned to each dovetail cut.
- the first housing component and second housing component are pressed together to align the first pin holes axially with the second pin holes, and the pins are inserted axially through each axially aligned first pinhole and second pin hole.
- a method of making a device housing involves providing a transparent lens with a front surface and a rear surface, and a stepped flange along at least a portion of the lens perimeter.
- the method includes injecting plastic onto the transparent lens perimeter, including the stepped flange, the plastic forming a plastic feature that has a front surface that is tangent to the front surface of the transparent lens, a rear surface that is planar with the rear surface of the transparent lens, and that extends outward from the sides of the transparent material away from a device width center line.
- the plastic feature is molded to the rear surface of the transparent lens at at least one of two ends of the device housing, and the plastic encapsulates a stepped middle surface of the transparent lens flange.

- the screws 404 may be affixed to the chassis 304 , the PCB 306 , or the housing 102 .
- the card access slot 406 is illustrated molded into the lens housing side wall for access to the card tray.
- a transparent lens 500 ( FIG. 5 ) includes a viewing window 104 , which is a transparent region of the lens for alignment with the active pixels of the display.
- the perimeter of the window may be defined by an opaque ink 504 , which is a layer applied to the back of the lens 500 .
- the ink is not applied to the viewing window 104 , circumscribing or extending along a portion of the window 104 .
- a stepped flange 540 extends along the majority of the sides, top and bottom edge perimeter 510 of the lens.
- the flange 540 may be continuous around the entire perimeter 510 of the lens 500 , or excluded in strategic areas to prevent damage to the lens if the device 100 is dropped or otherwise subjected to a shock.
- the example lens 500 does not include a flange 540 at the four corners of the lens, to help avoid breakage at these corners in the event the device is dropped at certain angles of impact.
- FIG. 6 is a bottom end cross section view of the lens 500 along line 6 - 6 shown in FIG. 5 , and showing the perimeter 510 and flange 540 .
- FIGS. 7A and 7B are zoomed regions of the cross-section view of FIG. 6 .
- FIG. 7B is identical to that shown in FIG. 7A , but with the addition of an adhesive layer 1401 and oleophobic coating 523 .
- ink layer 504 can be seen along with detail of the flange 540 .
- the edge portion 510 comprises three chamfers 544 , 546 , and 548 .
- the flange portion 540 itself may be bounded by two chamfers 546 , 548 , with a straight/flat surface 550 between.
- An inside corner radial geometry 542 may separate the bottom chamfer 544 from the first chamfer 546 bounding the flange 540 .
- the transparent lens flange 540 thus has a stepped geometry.
- the machined step in the transparent material provides an increased bond surface area.
- the chamfers 544 , 546 , and 548 are applied to all sharp corners of the transparent material to remove microscopic edge cracks from the cutting process and assist with molding.
- a machined radial geometry at 542 can be advantageously employed on the inside corner to reduce stress concentrations caused by the otherwise abrupt geometry change that would occur if the corner were square.
- the flange surface to be bonded with the plastic during molding can include a joint adhesive 1401 .
- the adhesive is deposited by spraying, printing, or otherwise dispensing, on the flange 540 , chamfers 544 , 546 , 548 , inside corner radial geometry 542 , and flange plane/flat surface 550 of the transparent lens.
- the adhesive improves the bond strength between the plastic and the transparent material.
- ink 504 is optionally included on the back surface of the lens.
- the lens may include an oleophobic coating 523 on the exterior surface. This surface can be a nano coating applied to the front surface of the lens to lower the surface energy of the transparent material and resist deposition of oils on the transparent material surface. Such materials are commonly referred to as anti-smudge or anti-fingerprint coating. This coating will prevent the joint adhesive 1401 from sticking to the front plane of the transparent material.
- the flange 540 is disclosed as having three generally parallel planes.
- the rear plane 522 is the back surface of the transparent material on which the ink 504 decoration is printed and to which a display 1200 is laminated.
- the rear plane 522 has, in the past, had plastic bonded to glass around the entire perimeter of the lens.
- Various embodiments do not bond plastic to this plane of transparent material along the sides of the display, thus permitting a narrowing of the device width necessary to accommodate the display and enhancing the edge-to-edge display experience for the user.
- the intermediate plane 524 of the transparent material which may be located at approximately the center of the lens thickness half way between the front and rear surfaces, serves to improve the mechanical bond between plastic and transparent material on the sides of the part without the need for plastic extending over the rear plane of the transparent material.
- the front plane 526 of transparent material is exposed to the user on the finished product and this surface does not have any plastic molded onto it. The display is viewed through this front surface of the transparent lens.
- the lens housing 800 (illustrated in FIGS. 8-10 ) of lens housing with laminated display 102 , includes the transparent lens 500 integrally molded with the lens housing side wall 902 .
- the lens 500 is insert molded with the lens perimeter plastic to create the desired geometry for the front lens housing, including a plastic rim integrally bonded to the transparent lens.
- the transparent lens 500 is inserted prior to molding the plastic portion 900 that includes the plastic side wall 902 , and is integrally bonded after the plastic resin is added and cured.
- the flange 540 geometry facilitates the plastic 902 forming smoothly tangential to both the front 526 and rear 522 planes of the transparent lens 500 .
- tangential could mean co-planar if both surfaces are flat, it also means “continuous” if the surfaces are curved, such that the surface is smooth at a location at which they meet.
- the plastic housing fills in the chamfer geometry 544 , 546 , 548 , as well as the inner corner radial geometry 542 , to create flush, consistent surfaces across the transitions from the transparent lens 500 to the plastic side walls 902 . No gaps are visible to a user, who will see at most a finely defined single line where transparent material 500 to plastic 902 transition occurs.
- a plastic feature 960 created in the process is described in more detail below.
- FIG. 11 is a flowchart that illustrates the basic procedures in the assembly, according to an embodiment.
- the transparent lens 500 is initially created S 100 , and (optionally) an oleophobic coating is applied to the lens S 110 .
- Adhesive is applied to the edge of the transparent lens 5120 .
- plastic is injected onto the lens perimeter 5130 (illustrated in more detail in FIGS. 12A-12E ).
- Optically clear light-curable resin 1403 is applied to the lens rear surface 522 S 140 , and the display module 1200 is placed on the resin 1403 .
- Front 4000 and rear 4010 optical sources are then used to cure the resin S 160 (see FIGS. 42 and 43 ).
- FIGS. 12A-12E illustrate this assembly process.
- an injection molding tool (injection mold) 1100 comprises a top portion 1102 and a bottom portion 1110 .
- the top portion 1102 has the transparent lens 500 placed in it.
- the bottom portion of the mold 1110 is brought into contact with the top portion 1102 , as shown in FIG. 12B , and then, as shown in FIG. 12C , the plastic portion 900 is injected into the mold 1100 .
- FIG. 12 E is an exploded view of the mold portions 1102 , 1110 and the transparent material/plastic 500 , 900 assembly.
- the holes 108 , 110 may be utilized so that the transparent lens 500 can be accurately located in an injection molding tool 1100 .
- the display module 1200 includes a rear glass (glass for the display, as defined herein, can also include other types of transparent material, such as plastic, etc. of sufficient strength and durability) 1205 , a front glass 1201 , and a polarizer 1203 .
- a display 1200 is laminated to an inside surface of the front lens housing 800 using liquid Optically Clear Resin (OCR) 1403 .
- OCR liquid Optically Clear Resin
- the OCR 1403 is dispensed on the lens 500 or display 1200 , and the lens and display are then bonded together.
- the OCR 1403 flows out from the viewing area and up the sides of this display module 1403 a to form a soft OCR cushion.
- the adhesive cushion 1403 is thus formed using overflow from the lamination process.
- the liquid adhesive 1403 permanently laminates the display module to the front lens.
- the polarizer 1203 and the front glass 1201 contact the optically clear resin (OCR) 1403 .
- OCR optically clear resin
- the display active pixel perimeter is illustrated by line 1202 .
- the molding process employed permits the display 1200 to be located in very close proximity to the side wall 902 , and thus permitting the active pixels to be positioned very close to the outer edge.
- the flanged edge structure 540 is particularly advantageous for accommodating the curved outer surface of the front lens housing with minimal spacing between the side wall 902 and the active pixels of the display.
- FIG. 14 includes two embodiments.
- a first includes no ink 504 on the rear surface 522 of the transparent lens 500 .
- the front surface boundary defining a front housing plastic-transparent material transition 530 ′ may extend further than an embodiment where the ink 504 is present and where the front surface boundary defines a front housing plastic-transparent material transition 530 that is closer to the device edge.
- the ink 504 can be applied to the rear surface 522 of the lens 500 along the side walls, such that the ink will frame the entire window 104 ( FIG. 1 ).
- the housing frames the viewing window 104 , the edge-to-edge appearance is maintained, the cost of applying ink is not incurred, and application of UV light through the front lens has better access to the OCR 1403 for curing during the assembly process (described in more detail below).
- prior art molding includes a side wall 902 and transparent lens 500 .
- a large plastic arm 1506 extends out into the transparent material surface.
- the arm 1506 creates a large surface area that blocks the viewing area of the display, and increases the size of the bezel around the display.
- the size of the housing for a given display must be larger in the prior art than is possible in the flange embodiment described herein.
- FIGS. 16 and 17 illustrate further limitations of the prior art.
- the flat lens 500 and display laminate 1200 uses opaque ink 504 , and the area behind the lens that accommodates the plastic arm 1506 required for molding can be seen to be quite large.
- the active pixels are moved further in, creating a greater gap between the active pixels and the outer perimeter of the device, than can be achieved with the construction described herein.
- the outer edge of the lens in the prior art extends past the edge of the display module, thus increasing the width of the device.
- FIGS. 18-20 illustrate the display and front housing section laminate 102 .
- the back of the display includes display circuitry 2104 ( FIG. 21 ) which is shown in FIG. 18 .
- FIG. 19 shows the side cross-sectional view illustrating an expanded full view of the lens and display laminate 102 .
- the display 1200 extends to the plastic housing 902 along the top wall.
- the bottom of the display shows a gap 2002 which is a tolerance of the display within the housing.
- the OCR may overflow and be cured 1403 a . The gap may or may not get filled when the OCR 1403 overflows.
- FIGS. 21 and 22 expanded cross sectional views of the lens housing and display laminate 102 and mesh and gasket assembly 2105 is illustrated.
- the front housing display assembly includes display driver circuits 2104 .
- a first embodiment is illustrated in FIG. 21 .
- the display 1200 includes rear glass 1205 , front glass 1201 , and polarizer 1203 .
- the rear display glass 1205 in the embodiment of FIG. 21 extends past the front display glass 1201 towards the device edge, and forms a fragile cantilever 1234 over the air gap 1405 .
- the illustrated display includes circuits 2104 which contains a display driver.
- a flex 2102 provides electrical connection between components of circuit 2104 and the PCB 306 .
- the display 1200 can be any conventional display, and may for example be a liquid crystal display, a light emitting diode display, an organic light emitting display, an AMOLED, or any other conventional display.
- the OCR 1403 flows between the lens 500 and the display front glass 1201 or polarizer 1203 , forming a laminate by the permanent bond between the display and the front lens.
- the liquid adhesive 1403 is shown stopping at the edge of the front glass 1201 .
- the OCR 1403 can potentially flow into and through the air gap 1405 or stop short of the edge of the front glass 1201 .
- the air gap 1405 exists between the front lens 500 and the glass display edge including circuit 2104 . Any liquid overflow into the air gap can potentially interfere with the positioning of the speaker mesh and gasket 2105 in this embodiment. Additionally, as can be seen in FIG.
- an alternate embodiment includes a structure 2202 molded into the lens housing 102 .
- the structure 2202 is integrally molded with the wall 902 and also along the back surface 522 of the transparent lens 500 (shown in FIG. 22A ) as part of the molding process when the lens housing is manufactured.
- the integrally molded structure is particularly advantageous. It permits the speaker mesh and gasket 2105 to be placed accurately in the lens housing 102 during assembly of the device 100 .
- Contact between the liquid adhesive 1403 and the mesh and gasket assembly 2015 can be minimized while still allowing some liquid adhesive to fill the small gap because larger gaps may be deliberately introduced in other locations, and thus the flow of the liquid 1403 is less restricted where the larger gaps exist.
- the bulk of the overflow will pool in the larger gap areas while a small amount partially fills the small gap in cross section before meeting resistance.
- the lens housing provides a seat for the mesh and gasket assembly 2105 , such that it can be reliably located in the lens housing without interference from the adhesive.
- the speaker opening 108 mesh and gasket assembly 2105 can thus be accurately positioned prior to display lamination—allowing it to reside underneath the glass cantilever, if desired.
- the lens housing detail 2202 created during the molding process may follow the footprint of the display flex 2102 so that it supports the ledge but never contacts glass of the display 1200 , but only the flex 2102 .
- direct support of the rear glass 1205 is also possible and would offer similar advantages for reducing the cantilever condition found in the unsupported glass ledge of FIG. 21 .
- the housing support may also advantageously include a chamfered edge 2212 (see also FIG. 22B ) shaped such that liquid adhesive that is used to laminate the display and lens will flow into and fill any small gap between the housing and the display ledge.
- the flex lead 2102 is thus well supported and protected if device 100 is exposed to mechanical shock.

- the structure 2202 height can be controlled during molding, to provide the appropriate seat for the display and display flex 2102 bonded to the rear display glass 1200 .
- the assembly may include a cushioning pad 1255 adhered to the rear of the display for protection from other parts of the device.
- the display driver 2104 is an integrated circuit attached to the rear display glass as shown in the FIGS. 21 and 22 .
- Liquid adhesive 1403 may fill the area around the display driver and bond the lens 500 , the housing 902 , and flex 2102 , and/or the rear display glass 1200 .

- the illustrated lens housing with laminated display 102 includes dovetail protrusions 940 along the side walls of lens housing walls 902 .
- the dovetail protrusions each include a snap hole 946 and a pin hole 942 (best seen in FIG. 32 ).
- the dovetail protrusions also contain angled faces 940 a at each end of the protrusion. These angled faces 940 a provide a significant advantage in that they prevent the plastic sidewall 902 from being able to rotate about the plastic-to-transparent lens bond.
- the internal chassis 304 includes mating dovetail cuts 3302 (best viewed in FIG. 33 ) for each of the dovetail protrusions 942 in the lens housing assembly. These dovetail cuts include matching angled faces 3302 a at each end of the cut to interface with the angled faces 940 a of the dovetail protrusions 940 . To assemble, the dovetail protrusions 940 are slid into the dovetail cut 3302 . The dovetail protrusions slide into the dovetail cuts in the internal chassis.
- the matching angled faces 940 a , 3302 a prevent the side walls 902 of the lens housing 800 from being able to move along the axis of the pin hole, thus preventing any torque from being exerted on the glue bond 1401 between the plastic housing flange 960 and transparent lens flange 540 .
- the pin hole 942 in the dovetail protrusion aligns with pinhole 3303 in the dovetail cut 3302 of the internal chassis assembly 304 .

- the pins 311 , 311 ′ are inserted into the pinholes when the pinholes are aligned as noted above.
- the pins 311 including retention features 311 a to snap or press into the pinholes.
- the smooth bore pin 311 ′ is held by friction fit. Friction will be exerted on the pin 311 ′ when inserted into the pin holes due to the layers of glass, the liquid adhesive 1403 , and the optional compressed pad 1255 (best seen in FIGS. 39 and 41 ), causing the chassis to push out against the pin 311 ′ and hold it in place during assembly.
- the vertical stack includes the PCB 306 assembly having shields 3902 positioned against the rear glass 1205 and the battery 312 .
- the rear housing includes a composite insert 200 with integrally molded plastic side walls 220 .
- the side walls include snap fingers 222 ( FIGS. 40 , 41 ) which engage the snap holes 946 in the lens housing dovetail feature 940 to hold the rear housing on the lens housing with laminated display assembly 102 .
- the rear housing side walls 220 cover the pins 311 , 311 ′ and further prevent them from sliding out along the axis of original insertion as illustrated in FIGS. 38 and 39 .
- the rear composite insert 200 is formed to the intended three-dimensional shape for the rear housing.
- the rear housing holds the battery against the PCB assembly and the display module in the stack up. Additionally, adhesive (not shown) could be included between the rear housing and the battery and or the chassis to secure the stack.
- the liquid optically clear resin (OCR) 1403 is dispensed between the lens 500 and the display assembly 1200 to bond the display to the front lens.
- the OCR 1403 flows out from the viewing area and up the side walls 902 between the display and the perimeter wall 902 of the lens assembly. This OCR 1403 forms a soft “cushion”.
- the adhesive cushion 1403 is thus formed using overflow from the lamination process.
- the liquid adhesive 1403 permanently laminates the display module 1200 to the lens 500 .
- the display in the illustrated example includes an integrated touch screen sensor.
- the transparent lens 500 extends past the edge of the display 1200 to provide a landing area for excess adhesive to flow during lamination.
- This extended lens shown in FIGS. 16 and 17 increases device size, whereas the flange 540 construction of the lens assembly housing 800 described herein avoids the extra width in the present flange construction for both transparent material and plastic.
- the transparent lens 500 is actually narrower than the display module 1200 .
- FIG. 14 shows that to achieve this, the plastic side wall 902 forms a planar continuation 922 of the rear surface of the transparent material 522 resulting in a single, planar display lamination surface created partially by transparent material and partially by plastic in the lens housing 800 .
- adhesive overflow 1403 a to coat the sides of the display module as shown in FIGS. 11 and 13 . Since the more traditional display lamination of FIGS. 16 and 17 occurs between two flat glass planes of the lens and display, there are no mechanical features to properly locate the display to the viewing window of the lens. Proper locating requires specialized and costly optical vision systems to align the viewing window of the lens to the active area of the display.
- the walls 902 of the lens housing 800 can provide a guide for positioning the display 1200 without use of specialized equipment.
- the plastic side wall 902 prevents the use of a side ultraviolet light for curing the OCR 1403 .
- FIGS. 42 and 43 show two alternate ultraviolet light techniques that can be used to cure the OCR 1403 and permanently bond the display 1200 and transparent lens 500 .
- the display polarizer 1203 (or possibly some other opaque member of the display 1200 ) blocks light from the back of the device, and the opaque ink 504 blocks ultraviolet light from the front of the device, such that a portion of the OCR 1403 behind the ink 504 will not receive UV light for curing.
- the opaque ink 504 is omitted from the rear surface 522 along the sides of the transparent lens, and the housing defines the viewing window 104 along the side walls.
- a rear ultraviolet light source 4010 may be used to cure the liquid OCR 1403 .
- the UV light can pass through the front 1201 and rear 1205 display glass in areas where electronic circuitry is not present.
- the front ultraviolet light source 4000 is used through the clear transparent lens 500 of the window 104 .
- the OCR 1403 will cure (harden) where direct exposure to ultraviolet light occurs.
- the flange plastic feature 960 to define the viewing along the side walls 902 , the need for opaque ink 504 printed on the rear surface 522 of the transparent lens 500 is avoided on the side walls. UV light is allowed to fully cure the liquid adhesive 1403 from the front, and the overflow 1403 a is cured by UV light from the rear.
- the edges of the display are inherently protected by the molded plastic sidewalls 902 of the transparent lens insert 500 molded plastic throughout the rest of manufacturing unlike traditional fabrication methods which leave the fragile glass display 1200 edges substantially exposed throughout shipping and until further manufacturing steps are completed.
- the disclosed device 100 has several additional advantages over existing structures. Side screws are avoided, the screw diameter increasing device thickness and the head thickness increasing device width. Snaps used alone loosen over time, provide limited directional constraints, and can disengage upon mechanical shock. Heat stakes provide poor serviceability, require clearance for heat steak heads, and use special equipment. Glue alone offers poor serviceability and complex process controls.

Abstract
Description
- The present application claims the benefit of U.S. Provisional Application No. 61/769,135, filed Feb. 25, 2013, U.S. Provisional Application No. 61/769,133, filed Feb. 25, 2013, U.S. Provisional Application No. 61/769,129, filed Feb. 25, 2013, and U.S. Provisional Application No. 61/769,131, filed Feb. 25, 2013, all herein incorporated by reference.
- It is becoming increasingly difficult to manufacture portable electronic devices including a battery and a display that are relatively compact, structurally robust, and take advantage of the largest available viewing area.
- In portable electronic devices, displays are frequently laminated to transparent cover lenses to improve optical performance and create a mechanical bond between the two parts. Since this bond is present over the entire viewing area of the display, it provides enough mechanical retention to eliminate the need for retaining the sides of the display by any other mechanisms. Thus, on either side of the display, one simply needs to have a thin cosmetic housing to cover the side of the display. However, in attempting to use a minimally thin cosmetic housing to cover the edge of the display, one encounters the problem of finding an appropriate connection mechanism between this cosmetic housing and other housings in the portable device that would not itself increase the device's size.
- Further complicating the search for a viable connection mechanism is the desire for reduced device thickness to improve user comfort when the device is in use or being transported.
- With regard to methods of making a transparent lens and plastic housing for a device, traditionally, the process of insert molding includes placing a stiff metal insert into an injection molding tool and then molding plastic features around the metal part. When complete, the plastic should be well integrated in the original metal part. Recently, advancements have been made in mold quality permitting pieces of glass or different transparent material to be used as the “insert” such that complex three-dimensional plastic geometry may be integrated with a sheet of transparent material.
- In a portable device, it is desirable for the transparent cover lens over the display to be integrated with overmolded plastic features, but this disadvantageously creates limitations as to the potential geometry for the glass or transparent insert. Over the viewing area of the display, one desires the transparent cover lens to be substantially thin and flat to result in an undistorted image and a small size for the finished device. Additionally, one desires that this cover lens also be as narrow and short as possible so that the resulting device is a minimal size. Conversely, the glass or transparent insert mold process prefers a large amount of material beyond the display to improve the bond between plastic and glass or different transparent material and ensure that the overmolded plastic does not detach from the transparent insert in the finished product.
- With regard to supporting transparent, and particularly glass, elements in a display device, portable electronic devices are exposed to frequent mechanical shocks over their lifespan, which can lead to display failures. Such displays are often laminated to a thick transparent cover lens, but the displays themselves are typically constructed using multiple sheets of thin glass, leaving them susceptible to breakage—especially at the edges of the glass sheets. Additionally, these thin sheets of glass often do not have matching widths or lengths as compared to other elements or housings, which may create a “ledge” of unsupported glass. The unsupported thin glass ledge acts as a cantilever if the device experiences mechanical shock, and is a potential source of display failures.

For example, the dimensions of some of the elements in the Figures may be exaggerated relative to other elements to help to improve understanding of various embodiments disclosed herein.
- The apparatus and method components have been represented where appropriate by conventional symbols in the drawings, showing the specific details that are pertinent to understanding the various embodiments and not obscuring the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.
- In the following description, for purposes of explanation, numerous specific details are set forth to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent to one skilled in the art that these embodiments can be practiced without these specific details. In some instances, structures and devices are shown in block diagram form for the sake of conciseness.
- The embodiments described herein can minimize device thickness, since a screw head, when using screws, can increase the device width by the head thickness, and can enhance reliability over snaps, which can loosen over time, have limited directional constraints, and can disengage upon mechanical shock. They can allow excellent serviceability over heat stakes that also require clearance for heat stake heads and avoid the need for special equipment and design efforts. Finally, they also allow excellent serviceability over glue and do not require the special equipment or complex process control that glue requires. These embodiments have great mechanical reliability and allow creation of robust attachment features over 3D formed glass or other transparent material, and have higher mechanical strength and less likelihood of scratching over the viewing area of the display over clear plastic housings.
- Using the process of insert-molding plastic over the transparent cover lens, plastic details can be integrated directly onto the transparent material. This allows the transparent cover lens to be sized smaller than the display, but use the plastic overmold to keep the display edges protected during manufacturing and in the finished device. By undersizing the cover lens and eliminating the need for a traditional device housing to display/cover lens assembly bond (replaced by the in-mold bond of plastic to glass or other type of transparent material), the process is capable of producing a smaller, more reliable portable device.
- In an embodiment of the disclosure, a transparent lens and differing plastic material housing include a transparent lens including a front surface, a rear surface, and a perimeter edge, the perimeter edge including a flange, a plastic housing affixed to the perimeter edge flange having a different material than the transparent lens, a portion that is tangent to the front surface of the transparent lens, and a portion that is tangent to the rear surface of the transparent lens.
- The transparent lens can be made of glass or can be made of a durable transparent plastic material that differs from the material of the side walls to which it is attached. As described herein, when the transparent lens is made of plastic, it is to be understood that this constitutes a different material than the plastic used in the side walls.
- In an embodiment, a display housing assembly is provided. The display housing assembly has a transparent portion and a plastic portion, and includes a transparent lens having a front surface, rear surface, and perimeter edge. The perimeter edge includes a flange. A plastic side wall of the plastic portion is affixed to the flange. The plastic sidewall has a front surface portion that is co-planar with the front surface of the transparent lens; and a rear surface portion that is co-planar with the rear surface of the transparent lens. This configuration forms front and rear planar surfaces, each of which has both transparent material and plastic. The assembly further including a display that is affixed to the rear planar surface using a display adhesive.
- In an embodiment of the disclosure, a device housing assembly has a display module including a front pane that may be transparent and a rear pane that may be transparent, the rear pane having a section longer than the front pane in at least one direction. The housing assembly further has a transparent lens and plastic housing, the transparent lens having a front and rear surface; and an adhesive between the front pane and the rear surface of the transparent lens. The housing includes a support structure molded to the rear surface of the transparent lens positioned proximally to the longer section of the rear pane and adjacent to the front pane, the structure providing mechanical support for the rear pane.
- Another embodiment of the disclosure is a thin cosmetic housing having dovetail features that assemble in a linear direction to an internal structural housing. The housing has cutouts to accept the dovetail features, thus constraining the cosmetic and structural housings in two axes.
- In assembling the housing, once the dovetail features are aligned, a pin is inserted through a hole in each dovetail perpendicular to the direction of dovetail assembly and into a hole in the structural housing. These pins constrain the cosmetic and structural housings in the third and final axis. Finally, a second thin cosmetic housing is snapped into snap holes on each dovetail of the first cosmetic housing which engage in the direction of the third axis. This housing fully covers the pins inserted previously which results in a better appearance of the finished device and prevents the pins from backing out far enough to disengage should they loosen over time. The attachment system results in a reduced width and thickness of the finished device
- More specifically, the housing comprises a first housing component with a plurality of dovetail protrusions, at least one dovetail protrusion of the plurality having a first pin hole through a thickness of the protrusion, and a second housing component with a plurality of matching dovetail cuts, at least one dovetail cut containing a second pin hole. The housing further has a plurality of pins. The first housing component is mated in a linear direction with the second housing component with each dovetail protrusion aligned to each dovetail cut. The first housing component and second housing component are pressed together to align the first pin holes axially with the second pin holes, and the pins are inserted axially through each axially aligned first pinhole and second pin hole.
- In an embodiment of the disclosure, a method of making a device housing involves providing a transparent lens with a front surface and a rear surface, and a stepped flange along at least a portion of the lens perimeter. The method includes injecting plastic onto the transparent lens perimeter, including the stepped flange, the plastic forming a plastic feature that has a front surface that is tangent to the front surface of the transparent lens, a rear surface that is planar with the rear surface of the transparent lens, and that extends outward from the sides of the transparent material away from a device width center line. The plastic feature is molded to the rear surface of the transparent lens at at least one of two ends of the device housing, and the plastic encapsulates a stepped middle surface of the transparent lens flange. A device housing that is made by this method is also included in an embodiment.

The card bay stiffener may for example be manufactured from metal, and secured usingscrews 404 affixed through each end of thestiffener 402. Thescrews 404 may be affixed to thechassis 304, thePCB 306, or thehousing 102. Thecard access slot 406 is illustrated molded into the lens housing side wall for access to the card tray. - A transparent lens 500 (
FIG. 5 ) includes aviewing window 104, which is a transparent region of the lens for alignment with the active pixels of the display. The perimeter of the window may be defined by anopaque ink 504, which is a layer applied to the back of thelens 500. The ink is not applied to theviewing window 104, circumscribing or extending along a portion of thewindow 104. - As can be seen in
FIGS. 5-7B , a steppedflange 540 extends along the majority of the sides, top andbottom edge perimeter 510 of the lens. Theflange 540, may be continuous around theentire perimeter 510 of thelens 500, or excluded in strategic areas to prevent damage to the lens if thedevice 100 is dropped or otherwise subjected to a shock. InFIG. 5 , theexample lens 500 does not include aflange 540 at the four corners of the lens, to help avoid breakage at these corners in the event the device is dropped at certain angles of impact. -
FIG. 6 is a bottom end cross section view of thelens 500 along line 6-6 shown inFIG. 5 , and showing theperimeter 510 andflange 540. -
FIGS. 7A and 7B are zoomed regions of the cross-section view ofFIG. 6 .FIG. 7B is identical to that shown inFIG. 7A , but with the addition of anadhesive layer 1401 andoleophobic coating 523. InFIG. 7A ,ink layer 504 can be seen along with detail of theflange 540. In an embodiment, theedge portion 510 comprises threechamfers flange portion 540 itself may be bounded by twochamfers flat surface 550 between. An insidecorner radial geometry 542 may separate thebottom chamfer 544 from thefirst chamfer 546 bounding theflange 540. Thetransparent lens flange 540 thus has a stepped geometry. The machined step in the transparent material provides an increased bond surface area. Thechamfers - With reference to
FIG. 7B , the flange surface to be bonded with the plastic during molding can include ajoint adhesive 1401. The adhesive is deposited by spraying, printing, or otherwise dispensing, on theflange 540,chamfers corner radial geometry 542, and flange plane/flat surface 550 of the transparent lens. The adhesive improves the bond strength between the plastic and the transparent material. Additionally,ink 504, is optionally included on the back surface of the lens. The lens may include anoleophobic coating 523 on the exterior surface. This surface can be a nano coating applied to the front surface of the lens to lower the surface energy of the transparent material and resist deposition of oils on the transparent material surface. Such materials are commonly referred to as anti-smudge or anti-fingerprint coating. This coating will prevent the joint adhesive 1401 from sticking to the front plane of the transparent material. - The
flange 540 is disclosed as having three generally parallel planes. Therear plane 522 is the back surface of the transparent material on which theink 504 decoration is printed and to which adisplay 1200 is laminated. Therear plane 522 has, in the past, had plastic bonded to glass around the entire perimeter of the lens. Various embodiments do not bond plastic to this plane of transparent material along the sides of the display, thus permitting a narrowing of the device width necessary to accommodate the display and enhancing the edge-to-edge display experience for the user. Theintermediate plane 524 of the transparent material, which may be located at approximately the center of the lens thickness half way between the front and rear surfaces, serves to improve the mechanical bond between plastic and transparent material on the sides of the part without the need for plastic extending over the rear plane of the transparent material. Thefront plane 526 of transparent material is exposed to the user on the finished product and this surface does not have any plastic molded onto it. The display is viewed through this front surface of the transparent lens. - The lens housing 800 (illustrated in
FIGS. 8-10 ) of lens housing withlaminated display 102, includes thetransparent lens 500 integrally molded with the lenshousing side wall 902. Thelens 500 is insert molded with the lens perimeter plastic to create the desired geometry for the front lens housing, including a plastic rim integrally bonded to the transparent lens. - With reference to
FIG. 10 , in the molding process, thetransparent lens 500 is inserted prior to molding theplastic portion 900 that includes theplastic side wall 902, and is integrally bonded after the plastic resin is added and cured. When the molding process is completed, theflange 540 geometry facilitates the plastic 902 forming smoothly tangential to both the front 526 and rear 522 planes of thetransparent lens 500. Although tangential could mean co-planar if both surfaces are flat, it also means “continuous” if the surfaces are curved, such that the surface is smooth at a location at which they meet. The plastic housing fills in thechamfer geometry corner radial geometry 542, to create flush, consistent surfaces across the transitions from thetransparent lens 500 to theplastic side walls 902. No gaps are visible to a user, who will see at most a finely defined single line wheretransparent material 500 to plastic 902 transition occurs. Aplastic feature 960 created in the process is described in more detail below. -
FIG. 11 is a flowchart that illustrates the basic procedures in the assembly, according to an embodiment. Thetransparent lens 500 is initially created S100, and (optionally) an oleophobic coating is applied to the lens S110. Adhesive is applied to the edge of the transparent lens 5120. Then, plastic is injected onto the lens perimeter 5130 (illustrated in more detail inFIGS. 12A-12E ). Optically clear light-curable resin 1403 is applied to the lensrear surface 522 S140, and thedisplay module 1200 is placed on theresin 1403.Front 4000 and rear 4010 optical sources are then used to cure the resin S160 (seeFIGS. 42 and 43 ). -
FIGS. 12A-12E illustrate this assembly process. InFIG. 12A an injection molding tool (injection mold) 1100 comprises atop portion 1102 and abottom portion 1110. Thetop portion 1102 has thetransparent lens 500 placed in it. The bottom portion of themold 1110 is brought into contact with thetop portion 1102, as shown inFIG. 12B , and then, as shown inFIG. 12C , theplastic portion 900 is injected into themold 1100. When themold 1100 is separated, the integratedtransparent lens 500 andplastic portion 900 is formed.FIG. 12 E is an exploded view of themold portions plastic holes transparent lens 500 can be accurately located in aninjection molding tool 1100. - With reference to
FIGS. 13-14 , thedisplay module 1200 includes a rear glass (glass for the display, as defined herein, can also include other types of transparent material, such as plastic, etc. of sufficient strength and durability) 1205, afront glass 1201, and apolarizer 1203. Adisplay 1200 is laminated to an inside surface of thefront lens housing 800 using liquid Optically Clear Resin (OCR) 1403. TheOCR 1403 is dispensed on thelens 500 ordisplay 1200, and the lens and display are then bonded together. TheOCR 1403 flows out from the viewing area and up the sides of thisdisplay module 1403 a to form a soft OCR cushion. Theadhesive cushion 1403 is thus formed using overflow from the lamination process. The liquid adhesive 1403 permanently laminates the display module to the front lens. As illustrated, thepolarizer 1203 and thefront glass 1201 contact the optically clear resin (OCR) 1403. The display active pixel perimeter is illustrated byline 1202. The molding process employed permits thedisplay 1200 to be located in very close proximity to theside wall 902, and thus permitting the active pixels to be positioned very close to the outer edge. Additionally, theflanged edge structure 540 is particularly advantageous for accommodating the curved outer surface of the front lens housing with minimal spacing between theside wall 902 and the active pixels of the display. -
FIG. 14 includes two embodiments. A first includes noink 504 on therear surface 522 of thetransparent lens 500. When this is the case, the front surface boundary defining a front housing plastic-transparent material transition 530′ may extend further than an embodiment where theink 504 is present and where the front surface boundary defines a front housing plastic-transparent material transition 530 that is closer to the device edge. Theink 504 can be applied to therear surface 522 of thelens 500 along the side walls, such that the ink will frame the entire window 104 (FIG. 1 ). By not including ink along the side walls, the housing frames theviewing window 104, the edge-to-edge appearance is maintained, the cost of applying ink is not incurred, and application of UV light through the front lens has better access to theOCR 1403 for curing during the assembly process (described in more detail below). - With reference to
FIG. 15 , prior art molding includes aside wall 902 andtransparent lens 500. In order to make the bond surface larger, a largeplastic arm 1506 extends out into the transparent material surface. Thearm 1506 creates a large surface area that blocks the viewing area of the display, and increases the size of the bezel around the display. As a consequence, the size of the housing for a given display must be larger in the prior art than is possible in the flange embodiment described herein. -
FIGS. 16 and 17 illustrate further limitations of the prior art. Theflat lens 500 anddisplay laminate 1200 usesopaque ink 504, and the area behind the lens that accommodates theplastic arm 1506 required for molding can be seen to be quite large. The active pixels are moved further in, creating a greater gap between the active pixels and the outer perimeter of the device, than can be achieved with the construction described herein. Unlike the present disclosure, the outer edge of the lens in the prior art extends past the edge of the display module, thus increasing the width of the device. -
FIGS. 18-20 illustrate the display and fronthousing section laminate 102. The back of the display includes display circuitry 2104 (FIG. 21 ) which is shown inFIG. 18 .FIG. 19 shows the side cross-sectional view illustrating an expanded full view of the lens anddisplay laminate 102. As can be seen fromFIG. 20 , along the top of thedevice 100, thedisplay 1200 extends to theplastic housing 902 along the top wall. The bottom of the display shows agap 2002 which is a tolerance of the display within the housing. Alternatively, the OCR may overflow and be cured 1403 a. The gap may or may not get filled when theOCR 1403 overflows. - With reference to
FIGS. 21 and 22 , expanded cross sectional views of the lens housing anddisplay laminate 102 and mesh andgasket assembly 2105 is illustrated. The front housing display assembly includesdisplay driver circuits 2104. A first embodiment is illustrated inFIG. 21 . Thedisplay 1200 includesrear glass 1205,front glass 1201, andpolarizer 1203. Therear display glass 1205 in the embodiment ofFIG. 21 extends past thefront display glass 1201 towards the device edge, and forms afragile cantilever 1234 over theair gap 1405. - Although a display includes other components and layers not specifically described herein for brevity, the illustrated display includes
circuits 2104 which contains a display driver. Aflex 2102 provides electrical connection between components ofcircuit 2104 and thePCB 306. Thedisplay 1200 can be any conventional display, and may for example be a liquid crystal display, a light emitting diode display, an organic light emitting display, an AMOLED, or any other conventional display. - When manufactured, as illustrated in
FIG. 21 , theOCR 1403 flows between thelens 500 and thedisplay front glass 1201 orpolarizer 1203, forming a laminate by the permanent bond between the display and the front lens. The liquid adhesive 1403 is shown stopping at the edge of thefront glass 1201. However since it is liquid, and the flow may be uncontrolled, theOCR 1403 can potentially flow into and through theair gap 1405 or stop short of the edge of thefront glass 1201. Theair gap 1405 exists between thefront lens 500 and the glass displayedge including circuit 2104. Any liquid overflow into the air gap can potentially interfere with the positioning of the speaker mesh andgasket 2105 in this embodiment. Additionally, as can be seen inFIG. 21 , there is no physical guide to preventmesh 2108 andgasket 2106 from being incorrectly positioned, such as being positioned too low on the transparent lens (e.g., positioned offset fromspeaker opening 108, or too far away from the device edge). Thedisplay cushioning pad 1255 is also shown. - With reference to
FIG. 22A , an alternate embodiment includes astructure 2202 molded into thelens housing 102. Thestructure 2202 is integrally molded with thewall 902 and also along theback surface 522 of the transparent lens 500 (shown inFIG. 22A ) as part of the molding process when the lens housing is manufactured. The integrally molded structure is particularly advantageous. It permits the speaker mesh andgasket 2105 to be placed accurately in thelens housing 102 during assembly of thedevice 100. - It also provides an integral dam, minimizing a flow of liquid adhesive 1403, and thus minimizing the liquid flow onto the area for mesh and
gasket assembly 2105. Contact between the liquid adhesive 1403 and the mesh and gasket assembly 2015 can be minimized while still allowing some liquid adhesive to fill the small gap because larger gaps may be deliberately introduced in other locations, and thus the flow of the liquid 1403 is less restricted where the larger gaps exist. The bulk of the overflow will pool in the larger gap areas while a small amount partially fills the small gap in cross section before meeting resistance. - The lens housing provides a seat for the mesh and
gasket assembly 2105, such that it can be reliably located in the lens housing without interference from the adhesive. Thespeaker opening 108 mesh andgasket assembly 2105 can thus be accurately positioned prior to display lamination—allowing it to reside underneath the glass cantilever, if desired. - It is envisioned that the
lens housing detail 2202 created during the molding process may follow the footprint of thedisplay flex 2102 so that it supports the ledge but never contacts glass of thedisplay 1200, but only theflex 2102. However, direct support of therear glass 1205 is also possible and would offer similar advantages for reducing the cantilever condition found in the unsupported glass ledge ofFIG. 21 . - The housing support may also advantageously include a chamfered edge 2212 (see also
FIG. 22B ) shaped such that liquid adhesive that is used to laminate the display and lens will flow into and fill any small gap between the housing and the display ledge. Theflex lead 2102 is thus well supported and protected ifdevice 100 is exposed to mechanical shock. -
FIG. 23 shows the lens assembly andmesh gasket assembly 2105 for the speaker port according toFIG. 21 , without the support structure.FIG. 24 shows the lens housing including thesupport structure 2202 according toFIG. 22A , but not including themesh gasket assembly 2105 for the speaker port.FIG. 25 shows the lens housing with the mesh andgasket assembly 2105 inserted. The mesh andgasket assembly 2105 may be positioned in the lens housing prior to display lamination, allowing the mesh to be well positioned underneath the display. The addedstructure 2202 prevents liquid adhesive from interfering with the speaker mesh andgasket 2105, preventing it from adhering to the rear of the lens or inadvertently sealing theaudio port 108. InFIG. 23 , nothing prevents misassembly of the mesh gasket assembly towards the bottom of the lens housing. This can lead to cosmetic problems visible through theacoustic port 108 or blockage of the acoustic port. Thestructure 2202 present inFIGS. 24 and 25 prevents misassembly of the mesh gasket assembly by providing a bottom edge against which to place the assembly. - The
structure 2202 provides a precision height support for thedisplay 1200 when the display is positioned into the front lens housing during assembly. Thestructure 2202 height can be controlled during molding, to provide the appropriate seat for the display anddisplay flex 2102 bonded to therear display glass 1200. As described above, the assembly may include acushioning pad 1255 adhered to the rear of the display for protection from other parts of the device. Thedisplay driver 2104 is an integrated circuit attached to the rear display glass as shown in theFIGS. 21 and 22 . Liquid adhesive 1403 may fill the area around the display driver and bond thelens 500, thehousing 902, andflex 2102, and/or therear display glass 1200. The lens housing preferably containssupport structure 2202 to prevent bending of the glass cantilever and contain theliquid adhesive 1403. -
FIGS. 26-28 illustrate the lens housing withlaminated display 102. Thewalls 902 can provide plastic features to accurately align adisplay module 1200 to the viewing window from the side. Additionally, edges 2802 can be provided to align the display on thelens housing 102. - With reference to
FIGS. 29-44 , the housing assembly will now be described. The illustrated lens housing withlaminated display 102 includesdovetail protrusions 940 along the side walls oflens housing walls 902. The dovetail protrusions each include asnap hole 946 and a pin hole 942 (best seen inFIG. 32 ). The dovetail protrusions also contain angled faces 940 a at each end of the protrusion. These angled faces 940 a provide a significant advantage in that they prevent theplastic sidewall 902 from being able to rotate about the plastic-to-transparent lens bond. - The
internal chassis 304 includes mating dovetail cuts 3302 (best viewed inFIG. 33 ) for each of thedovetail protrusions 942 in the lens housing assembly. These dovetail cuts include matchingangled faces 3302 a at each end of the cut to interface with the angled faces 940 a of thedovetail protrusions 940. To assemble, thedovetail protrusions 940 are slid into thedovetail cut 3302. The dovetail protrusions slide into the dovetail cuts in the internal chassis. The matching angled faces 940 a, 3302 a prevent theside walls 902 of thelens housing 800 from being able to move along the axis of the pin hole, thus preventing any torque from being exerted on theglue bond 1401 between theplastic housing flange 960 andtransparent lens flange 540. When assembled, thepin hole 942 in the dovetail protrusion aligns withpinhole 3303 in the dovetail cut 3302 of theinternal chassis assembly 304. Thecylindrical pin 311 is inserted into the axially aligned pin holes. The pins hold the chassis on the front lens housing during assembly. The cylindrical pin may include a retention feature 311 a (FIG. 35 ) or have a smooth bore as shown inFIG. 36 . -
FIGS. 29-41 illustrate the assembly of lens housing withlaminated display 102 to theinternal chassis 304, and the final assembly of the device housing. Thepins pins 311 including retention features 311 a to snap or press into the pinholes. Thesmooth bore pin 311′ is held by friction fit. Friction will be exerted on thepin 311′ when inserted into the pin holes due to the layers of glass, the liquid adhesive 1403, and the optional compressed pad 1255 (best seen inFIGS. 39 and 41 ), causing the chassis to push out against thepin 311′ and hold it in place during assembly. The vertical stack includes thePCB 306assembly having shields 3902 positioned against therear glass 1205 and thebattery 312. - The rear housing includes a
composite insert 200 with integrally moldedplastic side walls 220. The side walls include snap fingers 222 (FIGS. 40 , 41) which engage the snap holes 946 in the lens housing dovetail feature 940 to hold the rear housing on the lens housing withlaminated display assembly 102. Once assembled, the rearhousing side walls 220 cover thepins FIGS. 38 and 39 . The rearcomposite insert 200 is formed to the intended three-dimensional shape for the rear housing. The rear housing holds the battery against the PCB assembly and the display module in the stack up. Additionally, adhesive (not shown) could be included between the rear housing and the battery and or the chassis to secure the stack. - Display Lamination onto a Transparent Insert Molded Lens
- The liquid optically clear resin (OCR) 1403 is dispensed between the
lens 500 and thedisplay assembly 1200 to bond the display to the front lens. TheOCR 1403 flows out from the viewing area and up theside walls 902 between the display and theperimeter wall 902 of the lens assembly. ThisOCR 1403 forms a soft “cushion”. Theadhesive cushion 1403 is thus formed using overflow from the lamination process. The liquid adhesive 1403 permanently laminates thedisplay module 1200 to thelens 500. The display in the illustrated example includes an integrated touch screen sensor. - In a traditional display lamination (
FIGS. 16 and 17 ) to flat transparent lens, lamination takes place to stand-alone glass without any plastic feature. As a result, the edge of the display module is exposed and may be damaged throughout additional manufacturing steps. Liquid adhesive may overflow past the edges of the display, but will not be positioned to protect the side of the display consistently as various embodiments described herein do. - In the prior art, the
transparent lens 500 extends past the edge of thedisplay 1200 to provide a landing area for excess adhesive to flow during lamination. This extended lens shown inFIGS. 16 and 17 increases device size, whereas theflange 540 construction of thelens assembly housing 800 described herein avoids the extra width in the present flange construction for both transparent material and plastic. In the preferred embodiment, thetransparent lens 500 is actually narrower than thedisplay module 1200.FIG. 14 shows that to achieve this, theplastic side wall 902 forms aplanar continuation 922 of the rear surface of thetransparent material 522 resulting in a single, planar display lamination surface created partially by transparent material and partially by plastic in thelens housing 800. - An additional benefit may be realized by
adhesive overflow 1403 a to coat the sides of the display module as shown inFIGS. 11 and 13 . Since the more traditional display lamination ofFIGS. 16 and 17 occurs between two flat glass planes of the lens and display, there are no mechanical features to properly locate the display to the viewing window of the lens. Proper locating requires specialized and costly optical vision systems to align the viewing window of the lens to the active area of the display. Thewalls 902 of thelens housing 800 can provide a guide for positioning thedisplay 1200 without use of specialized equipment. - Traditional display lamination to a flat transparent lens uses liquid adhesive which is cured using ultraviolet light shined through the viewing window of the lens. A side ultraviolet light is then employed to cure the liquid adhesive that the front UV light cannot reach, specifically the areas where the front light sources are blocked by the
opaque ink 504 on thelens 500. - In the present embodiment, the
plastic side wall 902 prevents the use of a side ultraviolet light for curing theOCR 1403.FIGS. 42 and 43 show two alternate ultraviolet light techniques that can be used to cure theOCR 1403 and permanently bond thedisplay 1200 andtransparent lens 500. - As shown in
FIG. 42 , the display polarizer 1203 (or possibly some other opaque member of the display 1200) blocks light from the back of the device, and theopaque ink 504 blocks ultraviolet light from the front of the device, such that a portion of theOCR 1403 behind theink 504 will not receive UV light for curing. According to the embodiment ofFIG. 43 , theopaque ink 504 is omitted from therear surface 522 along the sides of the transparent lens, and the housing defines theviewing window 104 along the side walls. - A rear
ultraviolet light source 4010 may be used to cure theliquid OCR 1403. The UV light can pass through the front 1201 and rear 1205 display glass in areas where electronic circuitry is not present. The frontultraviolet light source 4000 is used through the cleartransparent lens 500 of thewindow 104. TheOCR 1403 will cure (harden) where direct exposure to ultraviolet light occurs. By using the flangeplastic feature 960 to define the viewing along theside walls 902, the need foropaque ink 504 printed on therear surface 522 of thetransparent lens 500 is avoided on the side walls. UV light is allowed to fully cure the liquid adhesive 1403 from the front, and theoverflow 1403 a is cured by UV light from the rear. - Finally, once the display lamination is complete, the edges of the display are inherently protected by the molded
plastic sidewalls 902 of thetransparent lens insert 500 molded plastic throughout the rest of manufacturing unlike traditional fabrication methods which leave thefragile glass display 1200 edges substantially exposed throughout shipping and until further manufacturing steps are completed. - The disclosed
device 100 has several additional advantages over existing structures. Side screws are avoided, the screw diameter increasing device thickness and the head thickness increasing device width. Snaps used alone loosen over time, provide limited directional constraints, and can disengage upon mechanical shock. Heat stakes provide poor serviceability, require clearance for heat steak heads, and use special equipment. Glue alone offers poor serviceability and complex process controls. - The benefits, advantages, solutions to problems, and any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as critical, required, or essential features or elements of any or all the claims.
