-one spacer member, is inserted in described gap, to set up structure connection between described optic panel and described support frame by bridging the width in described gap.
Another aspect of the present utility model provides a kind of method for manufacturing auto-stereoscopic display, and described auto-stereoscopic display includes a display floater, and to use a pel array to show video data, described method includes:
-optic panel is provided, described optic panel is oriented parallel to described display floater, described optic panel includes an array of optical elements, to boot up the light sent by respective pixel array group in mutually different side, enables to three-dimensionally watch described video data；
-provide a support frame, described support frame limit a frame openings, described optic panel is held in place along the periphery of described optic panel, described frame openings at least one greater in size than described optic panel；
-described optic panel is inserted in described frame openings, thus between described support frame and described optic panel, form at least one gap；And
-spacer member is inserted in described gap, to set up structure connection between described optic panel and described support frame by bridging the width in described gap.
Above-mentioned measure provides a kind of optic panel, and this optic panel is used for guiding the light sent by display floater in a different direction, is enable to three-dimensionally watch display video data on a display panel.Such optic panel itself is from known to auto-stereoscopic display field, and includes lenticular lens array and parallax barrier.Width, height and the aspect ratio that optic panel is generally of is similar to the width of display floater, height and aspect ratio, and wherein the deviation in width and/or height is typically the least and purpose and is in order at the reason of manufacturability.Optic panel will be installed in auto-stereoscopic display.For this purpose, auto-stereoscopic display is equipped with one for the framework (that is, support frame) keeping optic panel.Support frame provides a frame openings, is used for from the sidepiece (i.e., circumferentially) of optic panel around optic panel.Support frame itself can be from known to auto-stereoscopic display field, such as, and the frame of auto-stereoscopic display.Noticing, support frame can be the integral part of auto-stereoscopic display, and specifically bearing load structure division.
Frame openings at least one size (such as, flatly or vertically) more than optic panel.Therefore, when around this optic panel, along described size, between this support frame and this optic panel, there is at least one gap.Due to this gap, on the direction along the width in this gap, this optic panel is not held in place by this support frame.Therefore, when optic panel suffers sufficiently large power, it moves up in the side in this gap.In order to prevent such movement, a spacer member is inserted in this gap, and this spacer member bridges the width in this gap, thus sets up structure between this optic panel and this support frame and connect.Therefore this spacer member is dimensioned, and maybe can present the size of the essentially equal to width in this gap.Here, the width in this gap refers to when head on watching this auto-stereoscopic display, the size of the elongate length (that is, the shorter one in two visible sizes in this gap) being essentially perpendicular to this gap in this gap.
If inventors have realised that optic panel is relatively heavy compared with display floater, then optic panel is installed to display floater and to be more specifically installed to the back light unit of display floater be disadvantageous, this is because this applies sizable pressure on a display panel.Such as, 42 " in auto-stereoscopic display, display floater (including its back light unit) may weight 3.4kg, but optic panel may weight 10kg.Even if weight difference is less, display floater retains the relatively brittle part of auto-stereoscopic display.By being provided about the support frame of optic panel, set up a structure can being held in place by optic panel from the sidepiece of optic panel.By providing the spacer member of a width for bridging the gap between support frame and optic panel, and by this spacer member is inserted in this gap, between support frame and optic panel, set up structure connect.Therefore, optic panel is held in place by support frame by spacer member.Advantageously, when optic panel by power (such as, gravity) time, optic panel the pressure applied is passed to support frame, thus avoids or reduce the pressure on more frangible display floater.Another advantage is, this spacer member freely can position along the length in this gap, thus the most fixing component greater flexibility than WO2007/096818 is provided when mounted, this is laterally fixed component and is limited in the back light unit of display floater be provided with the position of screw hole.
Alternatively, this spacer member can be formed by a pair chock, and this is bonded with each other after being arranged for chock in being inserted into this gap, to set up the structure connection of the width bridging this gap.Chock is the conical by its shape with triangular cross section.Chock becomes known for the gap between filler body or interval.Another term for such chock is chock pad (shim).Of the present utility model using a pair chock being bonded with each other in this respect, reason is that chock is mechanically interacted to form connected structure by this.This connected structure is sized so that it bridges the width in this gap, thus provides the structure between optic panel and support frame to connect.Inventors have realised that a pair chock is highly suitable as spacer member.Its reason is, a pair chock may be used for being formed the most adjustable connected structure, never allows this to chock for bridging the gap of multiple different in width.Specifically, a pair chock may be used for being formed the stacked structure with two parallel side portions, and the distance between wherein said two parallel side portions is variable to the mode of chock according to stacking this.Advantageously, a pair given chock may be used for bridging the gap of varying dimensions.Inventor has realized that further, compared with the most fixing component of WO2007/096818, chock is provided more preferable structure to connect by this, because the most fixing described component is attached to back light part by screw, thus provides the dots structure that pressure is unevenly assigned to back light part to connect.But, chock is provided an elongated structure to connect between optic panel and support frame by this, optic panel the pressure applied more balancedly is assigned to support frame by this elongated structure connection.
Alternatively, this includes an angled sides with texturizing surfaces to each in chock, engaging the angled sides of another in chock for this, and chock is inserted in this gap by this, wherein said angled sides face each other connects to set up this structure.Here, term texturizing surfaces refer to its surface at least part of on include the surface of vertical deviation (vertical deviation).There is provided texturizing surfaces, so that chock can the most preferably be engaged by this, namely by means of the friction occurred between corresponding surface or interlocking.Advantageously, it is to avoid this to chock owing to being applied to this to causing individual chock to slide away from mutually departing from easily caused by power each other on chock.Advantageously, by angled sides face each other, forming a connected structure, this connected structure provides two parallel side portions, and described parallel side portions can be depressed against optic panel and support frame.Noticing, depending on the precise shapes of chock, angled sides is also known as the hypotenuse of right angled triangle.Advantageously, chock can be firmly wedged in this gap by this, so that it is guaranteed that the stable stable installation coordinating and similarly guaranteeing optic panel.
Alternatively, this is to be formed by corresponding hackly surface the texturizing surfaces of chock, and the hackly surface of described correspondence is by interlocked with one another and be bonded with each other.Hackly surface improves this joint to chock further, this is because hackly surface makes this can be by interlocked with one another and be bonded with each other to chock.Advantageously, it is provided that the more stable installation of optic panel.

-the second chock, is inserted in this wedge gap, to engage with this first chock.
First passing through and this first chock is attached to this support frame and/or this optic panel, this second chock can be easily inserted in formed wedge gap, to set up the connected structure that this optic panel is structurally attached to this support frame.Therefore, auto-stereoscopic display is obtained by a usual manner optic panel being installed to support frame.
Alternatively, chock is made up by this of plastics or rubber.For multiple different reasons, plastics and rubber are fit closely, and reason includes their flexibility.Such as, each chock can be made up of acrylonitrile-butadiene-styrene (ABS) (ABS) or other kinds of thermoplastic.Specifically, flexible so that chock can be more securely wedged in this gap by this, namely by slightly deforming with the local shape in the gap between matching optics panel and support frame.
Alternatively, this has cleat size to each width along gap in chock, between 0.5 times and 0.75 times of this cleat size generally width in this gap.By making angled sides face each other stack this to chock, it is thus achieved that having the connected structure of a height, this most at least bridges the width in this gap.Therefore, chock can be firmly wedged in this gap by this.
Alternatively, at least one size described is the longitudinal size of the width along auto-stereoscopic display, or the lateral dimension of the height along auto-stereoscopic display.
Alternatively, this spacer member is made up of machinery inflatable (mechanically expandable) structure, and this machinery expandable structure is arranged for when being inserted in this gap expanding with the width bridging this gap.Therefore this spacer member is made up of the mechanism allowing this spacer member to expand at least one direction.Advantageously, this spacer member can primitively present the external dimensions easily coordinating this gap, so that this spacer member can be easily inserted in this gap.After the insertion, then this spacer member can be made to expand, to be firmly wedged in this gap.
Alternatively, this spacer member is screw anchor type (screw anchor-type) structure.Screw anchor is known structure, and when screws are inserted, screw anchor expands.This spacer member can construct in a similar fashion, because it expands when inserting screw or similar structures.
Alternatively, this spacer member can be formed by a pair chock, and this structure that chock is mutually engageable to set up the width bridging this gap connects, and in the method manufacturing auto-stereoscopic display, inserts this spacer member and include:
-the first chock in chock is inserted in this gap by this, to provide a wedge gap between this support frame and this optic panel；And
-the second chock in chock is inserted in this wedge gap by this, to engage with this first chock.
The said method manufacturing auto-stereoscopic display is easily, because each can be easily inserted separately in this gap in chock, the most only forms connected structure after described being inserted in gap, in order to be firmly wedged in this gap.
Alternatively, before the method for manufacture auto-stereoscopic display is additionally included in this second chock of insertion, this first chock is attached to this support frame and/or this optic panel.By this first chock is attached to this support frame and/or this optic panel, it is possible to obtain this more stable cooperation to chock, and similarly can obtain the more stable installation of this optic panel.
Alternatively, except referring initially to gap, at the opposite side portion of optic panel, between support panel and optic panel, form a relative gap, and this auto-stereoscopic display include another spacer member of being inserted in this relative gap.Therefore optic panel is held in place by support frame by the spacer member of two opposite side portions.It can be advantageous to easily this optic panel is centered relative to this support frame frame.
In the auto-stereoscopic display of the present invention, by providing a pair chock, provide an elongated structure to connect between optic panel and support frame, optic panel the pressure applied more balancedly is assigned to support frame by this elongated structure connection.
