Description

Multi image display unit

Technical field

The present invention relates to advertisement and show, particularly, relate to and be used for the compact display device that the order demonstration is formed on a plurality of images on the single transparent body.

Background technology

Arrival along with the modern display ads epoch, for highdensity consumer, the restriction of advertising budget and limited display position, make to showing that at each lively display position place the demand of a plurality of advertisements significantly increases, a plurality of advertisers can be benefited from single position, same gray a plurality of different products can be shown.Having proposed a variety of distinct methods and equipment makes and shows this series advertisements.Many such equipment comprise heavy relatively mechanical organ, and these mechanical organs drive with the complicated driving mechanism that need have mechanical precision to a certain degree.Thereby except that the expense of original manufacturing, the user goes back the maintenance cost of demand side to costliness.

In addition, the operation of these driving mechanisms is easy to produce the noise content that does not expect to have at present.Usually, these equipment are used in public retail channel or other common point.The noise level of driving mechanism often surpasses the background music of playing in this type of position.Therefore, noise has destroyed the integrated environment that the retailer sees at ad display screen placement location place.

A kind of such device that uses at advertisement field has transparent picture screen, this transparent picture screen comprises the mosaic texture (mosaic) of four discrete pictures that formed by plurality of pixels, these pixels are shot through with predetermined arrangement, so that pass through four different positions with respect to the accurate positioning screen of cell mask (grid mask), can select each in these images, cell mask is covered all pixels except that the pixel of selected image.Pressing plate with hold-down plate surface is installed on the picture screen, and it can move through accurate patterns and select pixel, thus projects images.A pair of arm is coupling on the pressing plate, applies eccentric drive power and drives pressing plate, thereby make pressing plate pass pattern definitely and advance.Yet this device does not provide any means to be used for not regulating mask effectively with respect to clear sheet under mask and screen have the situation of registration fully mutually.

The U.S. Pat 4 of authorizing people such as Atkinson, 897, a kind of another equipment that contains the translucent image screen is disclosed in 802 (the transferring the application's assignee), this translucent image screen comprises the mosaic texture of the discrete picture that is formed by less relatively translucent pixel, these translucent pixels are interlaced and be arranged to each group uniformly, with the hole pattern that on permanent mask, forms (aperture pattern) sequence alignment.This equipment demonstrates good job specification.Yet this equipment comprises the drive motor that is installed on each each angle of device, is used for being presented at the discrete picture that forms on the mosaic texture with respect to cell mask skew mosaic texture with order.In addition, this equipment does not provide any means to regulate effectively relative to each other or mask or mosaic texture, with alignment mask and mosaic texture easily under the situation of not aiming at fully in mask and mosaic texture.

Disclose another kind of prior art equipment in the U.S. Pat 5,440,214 (transferring assignee of the present invention) of authorizing Peeters, it is designed to order and shows a plurality of images that are formed on the sheet material.Disclosed this equipment is a kind of low cost, high efficiency device in this patent, and it can show a plurality of high-resolution images in proper order in mode fast and accurately.Although this equipment can generally be accepted commercial, this device fabrication is got up relatively expensive, and also exists a difficult problem in the adjusting of aiming at aspect keeping.

In order to obtain the high-quality display of each image, hole in the mask and the compatible portion in the mosaic texture must keep very little.In most of situations, these holes are approximately 1mm ², but this can change.Have under the very undersized situation in the hole, it is important when setting whole unit and when whole unit is worked, bore portion to be positioned on the corresponding image section definitely and accurately.Exist any misalignment and all can cause the observer to see the part of another image that intersperses with first image, perhaps see " ghost image " alleged on the term.The tolerance that obtains high quality graphic can be low to moderate 1/100 millimeter.

Another important problem is that image and mask should keep each other in intimate contact, so that when certain angle is watched image, sees that the possibility of another mosaic image is minimized.

These may influence in the problem of picture quality some can enlarge because of the wearing and tearing of temperature, bump, vibration and whole unit.

As above indication, be appreciated that, press for the display device that a kind of compactness is provided, it can be made at an easy rate and allow and regulate effectively, so that mosaic texture and mask are held in appropriate spatial relationship, thereby allow when one in image on the mosaic texture and the hole pattern on the mask is offset with respect to another, image and hole pattern be registration accurately.

It should be clearly understood that if herein with reference to the publication of prior art in Australia or what his country in office, this is with reference to not constituting this approval that this publication becomes the part of this area common sense.

Summary of the invention

The present invention relates to multi image display unit, it can overcome at least one of above-mentioned defective at least in part, perhaps can offer a kind of useful or commercial selection of consumer.

In one form, there is a kind of display device in the present invention, this display device shows sequentially and the corresponding some groups of image parts of discrete picture staggered on transparent mosaic texture that by being formed on the hole pattern in the opaque substantially mask this display device comprises:

I. shell comprises:

A. pressing plate spare;

B. at least one pressing plate base;

C. the mask holder assembly is used for installing releasedly described mask thereon;

D. at least one adjusting part is used for regulating the position of described mosaic texture with respect to described opaque mask when it is regulated; And

E. driven unit comprises installation component, is used for correspondingly thereto installing described mosaic texture, and can operate and be used in corresponding to the predefined paths of described hole pattern driving described mosaic texture;

Described regulating device is adapted to pass through along predefined paths and regulates the location of described mosaic texture with respect to described opaque mask, so that selectively the corresponding constituent element and the corresponding described hole of described image aligned.

A kind of characteristic that does not typically expect to have is, mosaic texture is appropriately being aimed at and operating this device after a period of time with mask, some misalignment a little that becomes of mask and mosaic texture.This will cause that the hole of mask aims at the several portions image pixel corresponding to a plurality of images, rather than with the alignment of pixels of an image only, thereby cause this equipment to show fuzzy double image.In relatively compact display device because the image pixel that is positioned on the mask has relative less size with the hole, and closely near the observer who shows, even therefore the misalignment of trickle degree also can cause the demonstration of the distortion double image do not expected.

Adjusting part can be optical alignment system usually, can comprise at least one sensor, be generally and be used for 2 or 3 image display devices (only level or vertical moving, perhaps one dimension moves) infrared sensor, and more preferably be used for 3 the sensor that 4 images show (level and vertical moving or two dimension move).This at least one infrared sensor is installed on the fixed position with respect to mosaic texture and/or mask usually.

This predefined paths is suitable for being controlled by programmable logic controller (PLC).PLC can be suitable for controlling mosaic texture or pressing plate with respect to the moving of mask, and at the mobile round-robin starting point place that is suitable for display device image is correctly aimed at respect to the hole pattern in the mask, PLC also can preferably control it.Adjusting part can suitably link with driven unit.

Pressing plate spare can suitably be the shape of basic rectangle.When the cross section is seen, pressing plate spare can have crooked front surface.This front surface can be semisphere or torispherical with smooth rear surface.Pressing plate can be suitably made by the plastics such as acrylic acid or polycarbonate or other transparent material such as glass.

The image mosaic structure suitably is installed into pressing plate and has stacked relation, and suitably be installed on the pressing plate, the image mosaic structure can be shifted with respect to stacked shadowing mask with pressing plate, so that shelter from some part of mosaic texture selectively, and be provided for carrying out projection by its other parts.Though preferably, pressing plate is carrying the image mosaic structure and is moving the image mosaic structure with respect to mask, and pressing plate also can carry mask and move mask with respect to mosaic texture.

Similarly, mosaic texture is generally rectangle, comprises a plurality of image pixels from a plurality of discrete pictures, and these discrete pictures are dispersed in the even figure on the mosaic texture, and corresponding to the hole pattern that forms on the mask.Thereby, mask can be placed on the mosaic texture, and in the two one with respect to another skew, with on hole on the mask and the mosaic texture, corresponding to the image pixel registration of one of discrete picture that forms on the mosaic texture, thereby show this image.This relativity shift can carry out continuously, with the hole on the mask with respectively organize the pixel order registration corresponding to the various discrete pictures that scatter on the mosaic texture.

According to generating by mosaic texture and showing any method in a lot of methods of a plurality of independent images, to make mosaic texture suitably, the pixel of mosaic texture is staggered with predetermined layout, so that pass through in different positions with respect to the accurate positioning screen of cell mask, can select each in these images, cell mask is covered all pixels except that the pixel of selected image, and these all are known, particularly in advertisement field.

Mosaic texture can be for being printed with the plastic sheet spare of mosaic image on it.Mosaic texture can be very thin, is complementary with the preferred crooked shape that can make sheet material and pressing plate spare front surface.Mosaic texture is mounted to the relation with pressing plate and mask tight spacing usually.

Inlaid sheet materials preferably comprises at least one mating holes within it.Suitable is, the hyalomere that mating holes limits in can the zone of opacity by mosaic texture assigns to provide.For example, zone of opacity can be arranged on the bottom of inlaid sheet materials, is positioned at outside the image mosaic structure.Transparent apertures can be arranged in the zone of opacity then.A more than mating holes can be set in mosaic texture, and the quantity of these mating holes and position depend on the degree that mosaic texture moves usually.

Mask is a rectangle on the whole, has opaque grid (grid work) that forms thereon, and this opaque grid limits the predetermined pattern of the hole formation that evenly separates substantially, carries out projection with blocking light by the zone of mask about 75%.The shape in this blocking-up character and hole depends on the number of the image in the demonstration and the content of mosaic texture usually.These holes are generally side edge length and are approximately the square of 1mm, but the yardstick in hole and shape can change according to the size of mosaic texture and configuration.

This opaque mask is preferably blocked back lighting and pass the image mosaic structure light-emitting except that being passed display aperture.Mask can be arranged to sheet material spare.

This mask sheet material also can preferably include at least one mating holes that is positioned at it.Suitable is that mating holes can be assigned to provide by the hyalomere that limits in the mask zone of opacity.For example, zone of opacity can be arranged on the bottom of mask sheet material, is positioned at outside the grid of establishing for blocking-up image mosaic structure.Transparent apertures can be arranged in the zone of opacity then.A more than mating holes can be set in mask, and the number of these mating holes and position depend on moving of mosaic texture usually.

Mutually correctly on time, the mating holes of mask and mosaic texture suitably is offset mutually in mask and mosaic texture.These mating holes can suitably be rectangular shape.This skew is suitable for carrying out along the vertical scale in hole.Most preferably, each mating holes only is displaced to this degree, in case promptly these holes stop vertically to aim at mutually, just not having light penetrates the corresponding opaque portion that is located on mosaic texture and the mask, and does not have light by these parts.Thereby this can allow no longer can sense this position to punctual sensor when mating holes, establishes correct alignment position thus.

Drive unit can comprise at least one linear actuators.Preferably, linear actuators has the step function part, and it has the output shaft that operationally is coupling on mosaic texture or the mask sheet material.This stepping linear actuators preferably is coupling on the PLC, with mobile in opposite direction output shaft, thereby realizes moving back and forth of mask or embedded film.

PLC can be provided and be used for making selectively the drive unit can mobile preset distance, with mosaic texture with respect to one section preset distance of mask dislocation, thereby with the image pixel of one of them discrete picture on the mosaic texture and the hole registration on the mask.In case realize this registration, PLC can work drive unit is failure to actuate, so that image can show the time quantum of preliminary election.After the time quantum of this preliminary election disappeared, PLC automatically made drive unit dislocation mosaic texture once more, with will be corresponding at the image section of the next discrete picture that forms on the mosaic texture and the hole registration on the mask.Continue this order, thereby with the discrete picture on the mosaic texture sequentially with mask on the hole pattern registration.

The predefined paths that is used for mobile mosaic texture can suitably comprise alignment stage and mobile phase, guarantee that at this alignment stage mask aims at the correct of mosaic texture, carry out the predetermined mobile step of mosaic texture at this mobile phase, to show each image of mosaic texture with respect to mask.Alignment stage can form the part of mobile phase, perhaps can side by side carry out with mobile phase to small part.

The alignment stage that should move can be included as the establishment correct alignment position, and mosaic texture moves with respect to mask.The mobile phase of mosaic texture is determined by the number and the orientation of various images in the mosaic texture usually.For example, if in the mosaic texture three images are arranged, and the biasing mutually in the band of several vertical orientations of these three images, then should move is that the reciprocal linearity of along continuous straight runs (one dimension) moves.Utilize four picture systems (wherein image is at square figure bias internal), need two dimension to move (level is with vertical) usually.More than one group of mating holes can be set, so that aim at mosaic texture and mask at both direction.

According to a particularly preferred embodiment, the alignment procedures that PLC carries out in 3 image configurations shown can be as follows.When starter gear or when the aligning that detects mosaic texture and mask goes wrong, infrared sensor will sense a kind of in the two states, that is:

A) sensor passes detection the light in each hole of aiming in mask and the mosaic texture.PLC is suitably programmed to when detecting this situation, and the PLC accessory drive moves the image mosaic structure along first direction.Along with image moves along first direction, the size of these mating holes will diminish usually gradually, up to sensor detect do not have light till, this is because these holes will be suitably no longer corresponding.It is the correct aligned position of mask and mosaic texture that PLC is suitably programmed to this is considered as, PLC is then by moving one section distance of programming in advance with image towards first direction, with second image is placed as with mask in the hole align, thereby allow its demonstration, PLC will move mosaic texture at predefined paths thus.Subsequently, PLC suitably calculates and turns back to center image to allow its programming number that shows required step, and after this, PLC will calculate and turn back to left image again to allow the programming number of the required step of its demonstration.Then, PLC advances mosaic texture, turns back to correct alignment position, and sensor is being monitored the light that passes each hole of aiming on mask and the mosaic texture simultaneously.When sensor stops to survey the light time of passing these mating holes, PLC is suitable for this once more as correct alignment position, and resets.Therefore, can check aiming at of the single part of the position of mosaic texture and each image or pixel and mask, thereby guarantee that the image mosaic structure aims at the correct of mask in each circulation.

B) the hole place that detects on mask and mosaic texture of sensor does not have light, PLC will move image along second direction, detect up to it and to pass mating holes and from thereon light, PLC suitably accessory drive carries out alignment procedures of describing in above-mentioned (a).

In the example of 2 image display systems or 4 image display systems, routine or circulation can change a little, but ultimate principle is identical.

Shell generally includes rear wall and housing.Shell integral body is rectangle, comprises a plurality of peripheral side wall that extend substantially vertically from rear wall, and it is dull and stereotyped that rear wall is generally.Rear wall normally is installed on the housing removedly, so that enter the inside of housing.Alternatively or additionally, one or more sidewalls of shell are removable.Portion is equipped with illuminace component in the enclosure, and illuminace component generally includes one or more light pipes spaced apart from each other.Also can adopt one or more reverberators, to strengthen the illumination of display device.

On second kind of form, the present invention is present in a kind of display device, is used for by being formed on the hole pattern in the opaque substantially mask, shows sequentially and the corresponding array image pixel of discrete picture staggered on transparent mosaic texture that this display device comprises:

I. shell comprises:

A. pressing plate spare has a plurality of hold-down arms mounted thereto; With

B. at least one pressing plate support member, each of this at least one pressing plate support member has the opening of a plurality of keyhole, be used for pressing plate spare being installed with respect at least one pressing plate support member, each opening has the bigger cross-sectional area part and the slotted portion of small cross section, the number of opening is corresponding to the number of the hold-down arm on the pressing plate spare

Wherein at least some hold-down arms are provided with at least one annular element, being dimensioned to of this at least one annular element can partly be inserted by the comparatively large cross-sectional area by respective openings in the installation process of pressing plate spare, and the pressing plate spare of installing can be remained contiguous this at least one pressing plate support member when the annular element adjacent slots.

The small cross sections part quilt of slit is sizing suitably, makes to allow to carry out moving fully on all directions.The larger cross-section part of slit suitably only is used for assembling; The opening that it allows annular element to pass keyhole before the position that pressing plate is slided in the small cross sections slit assembles.Suitable is that annular element can be tygon packing ring or analog.Suitable is, pressing plate is fix in position by this way, yet pressing plate still can be suitable for because thermal expansion etc. are former thereby expand and shrink.Alternatively, pressing plate can be suitable for driven device and move, and moves the mosaic texture that links whereby.

Pressing plate support member or guide rail can be substantially extend around shell, thereby allow pressing plate supported at periphery.The opening that is shaped can all be positioned on the identical direction then.

Can there be a more than annular element and each opening to link, a bigger annular element and a less annular element are preferably arranged, this bigger annular element is located between pressing plate spare and the pressing plate support member, this less annular element is located at after the pressing plate support member, when assembling with respect to the pressing plate support member with convenient pressing plate, the wall of pressing plate support member is contained between these two annular elements.In these two annular elements one or two can be made by low-friction material, and for example various types of plastics have this character.

Hold-down arm can comprise machine screw or like, and pressing plate can have several corresponding openings within it and hold screw.Annular element can be installed on the pressing plate spare removedly.When pressing plate spare being assembled on the pressing plate support member, screw can be removed before will assembling with respect to screw than big annular element, and pressing plate spare can fit in the opening of keyhole then, and afterwards, less annular element can be installed on the screw.Alternatively, hold-down arm and annular element can be designed to that pressing plate spare just can be assembled on the supporting guide when annular element has been installed on the screw.

In the past, keeping the crooked pressing plate of mask and image mosaic structure to be installed on the shell on it at the place, fixed position.Yet in this embodiment of the present invention, by using the opening of keyhole, pressing plate can remove at an easy rate, perhaps if desired, can change at an easy rate.This another advantage on the one hand of the present invention is that the pressing plate that is made of acrylic compounds, polycarbonate or glass does not need framework or further reinforces usually, because supporting guide can keep it to put in place.

In the third form, the present invention is present in a kind of display device, is used for by being formed on the hole pattern in the opaque substantially mask, shows sequentially and the corresponding array image of discrete picture staggered on transparent mosaic texture that this display device comprises:

I. the pressing plate spare that has a plurality of openings within it;

Ii. many long and narrow keepers;

Iii. mosaic texture, have an opposite side, apical margin and root edge and corresponding to a plurality of slotted openings of these a plurality of keepers, at least one opening is positioned contiguous each side, an opening is positioned the apical margin or the root edge of contiguous mosaic texture, the opening of contiguous each side is orientated apical margin or the root edge that is basically parallel to mosaic texture, and the opening of contiguous apical margin or root edge is orientated the side that is basically parallel to mosaic texture.

According to this aspect of the invention, can keep the image mosaic structure with respect to pressing plate spare with reaching 3 keepers.This can suitably allow pressing plate spare and mosaic texture to expand independently of one another and shrink.The replacing that this another advantage on the one hand is a mosaic texture is very simple.Because need change mosaic texture when each hope changes the advertisement that will show, so this replacing should as far as possible simply and as quickly as possible be finished.

Each of these a plurality of long and narrow keepers can suitably be to fasten nail or pin, and each fastens nail or pin can be removable maybe can fixing.Pin can suitably be cylindrical, has radial dimension.Opening in the pressing plate can preferably closely hold these register pins, is positioned at it to guarantee them.These elements can be suitably longer, are enough to be contained in the opening of pressing plate spare, and the protruding mosaic texture of being close to pressing plate spare that supporting.These elements can be assembled in the opening, then, the opening of the mosaic texture of assembling subsequently or the opening in the mosaic texture and pressing plate and the keeper that passes these openings are aimed at.

Mosaic texture has an opposite side, apical margin and root edge and corresponding to a plurality of slotted openings of these a plurality of keepers, at least one opening is positioned contiguous each side, an opening is positioned the apical margin or the root edge of contiguous mosaic texture, the opening primary orientation of contiguous each side is to be parallel to the apical margin of mosaic texture or root edge, and the opening primary orientation of contiguous apical margin or root edge is the side that is parallel to mosaic texture.Three openings are arranged usually, the root edge of a contiguous mosaic texture, the arbitrary side of vicinity.Opening in the mosaic texture suitably is a slotted opening, has vertical scale and breadth wise dimension.Suitable is that these openings carry out orientation according to their vertical scale.The vertical scale of these openings is preferably greater than the radial dimension of pin, is generally at least 2 times.The breadth wise dimension of opening can be reduced to minimum with auxiliary with the misalignment of mosaic texture only less times greater than the radial dimension of pin.

In order to change image, can remove this three register pins, image is skidded off from the mask back, make new images slip back to the position, and change register pin, start unit then.Optical alignment system as previously described can be responsible for mosaic texture is correctly aimed at mask subsequently.

The 4th kind of form, the present invention is present in a kind of display device, is used for by being formed on the hole pattern in the opaque substantially mask, shows sequentially and the corresponding array image pixel of discrete picture staggered on transparent mosaic texture that this display device comprises:

I. shell;

Ii. mask has the hole that an opposite side, apical margin and root edge and at least two row separate, and row are positioned arbitrary side of contiguous mosaic texture; And

Iii. the mask installing component of installing with respect to shell, this mask installing component comprises a plurality of elasticity toothed elements, these elasticity toothed elements are from wherein stretching out to engage with hole on the mask, and mask remained under the tension force, at least some toothed elements are positioned towards the middle body of installing component, it is designed and sized to and closely is contained in the corresponding hole, thereby the middle body of location mask definitely, at least some toothed elements are positioned towards the Outboard Sections of installing component, its size is designed to be contained in loosely in the corresponding hole, thereby allows the expansion and the contraction of mosaic texture or installing component.

According to this aspect of the invention, mask also is provided with two borings (bore) that separate of row, and these borings are adjacent to the relatively vertically end of mask and form, and these borings limit and are used for installing releasedly with respect to shell the installation boring of mask.

As previously mentioned, embedded film contacts each other closely with mask, and this point may be very important.In the past, by stainless steel band being assemblied in the end of mask,, obtain this close contact with this with respect to pressing plate and image mosaic structure mask kept smooth and to put in place by means of bonding agent.Yet because mask is limited parts of life-span, this is a way of a high price.According to this aspect of the invention, mask can keep putting in place by means of the spring comb (profile cutspring comb) of a pair of setting cutting.Suitable is, each side of mask all is provided with comb, and wherein the comb that is provided with on mask one side can deflection, and the comb that opposite side is provided with is preferably fixing.This will help to keep the position and the orientation of mask.

Mask installing component of the present invention preferably includes a plurality of elasticity toothed elements, and these elasticity toothed elements are stretched out engaging with the hole of mask from the mask installing component, and mask is remained under the tension force.These toothed elements can be provided with the mask installing component is whole, and perhaps these toothed elements can remove from installing component, or all remove independently from the mask installing component.Should be understood that, can produce the display device of different size.A kind of straightforward procedure of easily making these different size devices is that the installing component of the elongation band shape of manufacturing indefinite length cuts into installing component the required length of concrete device then.By tooth is separated but can insert installing component, can change the length of installing component, and the tooth of centrally-located and the quantity of external teeth and configuration can change also.

In practice, for demonstration, be difficult to the folding accurate comb shape spring also longer than about 600mm than large scale.Therefore, will be suitable for use in the central authorities of mask than short mask installing component.Then, with being positioned at a plurality of independent fabricated section that separates on the device residual altitude, can assist this mask installing component, so that the mask on the pressing plate is tightened to its limit.At the opposite side of mask, can assist this mask installing component once more with the separation fabricated section of equal number.Thereby such setting can allow mask film to expand with the need owing to the influence of temperature and moisture and shrink, but importantly, will not allow mask film in its position deflection to take place.

At least some toothed elements are positioned towards the middle body of installing component, its size is designed to closely be contained in the corresponding hole, thereby the middle body of location mask definitely, and at least some toothed elements are positioned towards the Outboard Sections of installing component, it is dimensioned to and is contained in loosely in the corresponding hole, thereby allow the expansion and the contraction of mosaic texture or installing component, and provide described some such toothed elements to be designed to allow image and/or pressing plate to expand or shrink, and middle part that can mobile image.

The length of these teeth also is applied to the amount of the tension force on the mask applicable to adjusting.The shape of these teeth can comprise a part towards mask central authorities " bending ", to assist with mask alignment in the enclosure.

The 5th kind of form, the present invention is present in a kind of display device, is used for by being formed on the hole pattern in the opaque substantially mask, shows sequentially and the corresponding array image of discrete picture staggered on transparent mosaic texture that this display device comprises:

I. shell comprises:

A. the pressing plate spare that has two sides, an apical margin and a root edge;

B. pressing plate installing component comprises:

I. the L shaped member of installing with respect to each side of pressing plate spare;

Ii. the support bracket of installing with respect to shell;

Iii. from the upwardly extending support extension of support bracket, coaxial substantially with L shaped member;

Iv. at the reduction friction component that supports between extension and the L shaped member, in order to strengthen the slippage of supporting between extension and the L shaped member.

When image-display units was built as 2 images or 3 elementary areas, importantly, when drive unit driving pressing plate passed predefined paths, the image mosaic structure kept along continuous straight runs to aim at mask.In the past, use the complex mechanism that has mechanical arm to realize this aligning.The problem of bringing is to carry out initial adjustment next horizontal centrally aligned mask and image mosaic structure along image and mask.Yet, according to an aspect of the present invention, use a simple spring clamp just can realize this aligning.

The pressing plate installing component can be to be similar to above-described parts or to be included in wherein.Usually, a pressing plate support component is arranged on the either side of pressing plate, it approximately is positioned at half place that outer cover height makes progress, but other position also can be adopted.

According to this aspect of the invention, the pressing plate installing component can comprise the L shaped member of installing with respect to each side of pressing plate spare.L shaped member is installed on the edge of each side of pressing plate spare usually, and can use any installing component.L shaped member has two arm members oriented perpendicular to each other basically usually, and one of these two arm members is being adjoined pressing plate spare, and another arm member substantially vertically stretches out from pressing plate.L shaped member is suitably made with for example plastics or metal.

The pressing plate installing component typically also comprises the support bracket of installing with respect to shell.This support bracket compatibly is mounted to towards the back of shell and is extended out towards the front portion of shell, stops at a free end.Support bracket can separate with the protruded arm of L shaped member.This bracket also can comprise a near part from extending the bracket free end.This part can be perpendicular to bracket, and can be well-suited for a guide member that is used for moving press plate spare.

The pressing plate installing component can also comprise that from the upwardly extending support extension of support bracket this support extension and L shaped member are coaxial substantially.This extension is normally near the part of the regulating part that extends up to installing component the outer casing bottom.This regulating part can suitably be a rod that extends through the respective threaded opening in the support bracket.This rod typically has at least one threaded portion, so that the rotation of rod can increase or reduce from the height of the upwardly extending rod of support bracket.Thereby this can be so that pressing plate spare can carry out perpendicular positioning.

Supporting between extension and the L shaped member, suitably comprising the reduction friction member that an arm with L shaped member links in order to the reduction friction component that strengthens the slippage between support extension and the L shaped member.An elastic component that links with support bracket also can be arranged, and it extends between support extension and L shaped member.This elastic component be suitable for when when side view is seen, be arc, and can laterally extend internally.The curved shape of this elastic component can make elastic component be suitable for strengthening the slippage of pressing plate spare.

Therefore, under the guiding of drive motor along continuous straight runs, the amount of friction that pressing plate spare can be minimum freely moves, and mask and mosaic texture when being conditioned with keeping parallelism.When the height of pressing plate increased with the size of unit and pressing plate, support component can be provided with ball bearing.

Be appreciated that for 4 elementary areas the pressing plate installing component can alternatively comprise a plurality of linear actuators, these linear actuators also are responsible for moving press plate.Linear actuators can be positioned near the top of this unit, and it axially extends down.This axle can deflection, to hold being displaced sideways of pressing plate.

For 4 bigger image-display units, be not that pressing plate is fixed along horizontal level, can be suitable for making pressing plate and move in vertical plane owing to be installed on 2 other drive units but make, preferably each all is a linear actuators to these 2 other drive units.Each linear actuators suitably is installed in pressing plate with a long and pliable and tough axle and installs on the bracket, and this pressing plate is installed bracket and preferably is installed on the pressing plate again.In when operation, the linear actuators of level can be in surface level moving press plate suitably, the combination of the vertical linearity actuator of left hand and the vertical linearity actuator of the right hand can be in vertical plane moving press plate.Flexible shaft can allow pressing plate to move independently in two planes.Most of weight of pressing plate is being carried by elastic component, and this elastic component is a spring typically, and the one end is installed in pressing plate and installs on the bracket, and the other end is installed on the point of fixity of display unit, is installed on the shell usually.Therefore, this can allow to use the quite low linear actuators of power to obtain required pressing plate displacement.

The 6th kind of form, the present invention is present in a kind of display device, is used for by being formed on the hole pattern in the opaque substantially mask, shows sequentially and the corresponding array image pixel of discrete picture staggered on transparent mosaic texture that this display device comprises:

Shell comprises:

A. pressing plate spare; With

B. be used to throw light on several illuminace components of mosaic texture, these illuminace components are installed with respect to member slidably, this slidably member can remove from shell and can disturbance pressing plate spare, mosaic texture or mask.

In the art, the maintenance of this unit must be carried out with cost effective and efficient manner.Remove outside the unit failure, lighting device is topmost loss parts in the unit normally.Because the installation of mask, image mosaic structure and pressing plate combination, the maintenance or the replacing of device feature are carried out in the front portion that therefore is difficult to pass according to routine device.In the past, use several loose-leaf systems that shell is separated into two parts or a plurality of part, so that touch lamp and lighting controller.

Yet in the present invention, the illuminace component by will device is installed in one slidably on the member, can overcome this difficulty, this slidably member can from shell remove and can disturbance pressing plate spare, mosaic texture or mask.According to this most preferred embodiment, slidably member can be one and skids off pallet.Preferably, along with pallet skids off shell, a plug and socket formula power-supply system can disconnect the electric power that offers lighting device, and the plug portion of this plug and socket formula power-supply system can be installed on the shell, and its socket part can be installed on the pallet.So, change the blowing bulb be installed on the pallet or fluorescent tube or any illuminace component and just become very fast now.

Detailed description of the present invention

According to an aspect of the present invention, provide a kind of many image display devices.

Referring to Fig. 1 to 3, the preferred embodiment of first aspect that the present invention may be better understood.

The display device of this embodiment by being formed on the hole pattern in the opaque substantially mask 11, shows sequentially and the staggered corresponding some groups of image parts of discrete picture that this display device comprises on transparent mosaic texture 10:

Shell comprises:

A. pressing plate spare;

B. at least one pressing plate base;

E. the driven unit that comprises installation component is used for correspondingly thereto installing described mosaic texture, and can operate and be used in corresponding to the predefined paths of described hole pattern driving described mosaic texture;

Described regulating device is adapted to pass through along predefined paths and regulates the location of described mosaic texture with respect to described opaque mask, so that selectively the counterpart and the corresponding described hole of described image aligned.

Usually, mosaic texture 10 is correctly being aimed at and is operating this device after a period of time with mask 11, the misalignment a little that may become of mask and mosaic texture.This will cause that the hole of mask aims at the image section corresponding to a plurality of images, rather than with aim at corresponding to the image section of an image only, therefore can cause device to demonstrate as shown in Figure 2 fuzzy double image.

The adjusting part of the preferred embodiment is an optical alignment system, comprise that is used for 2 or 3 image display device (only levels or only vertical moving, perhaps one dimension moves) the infrared sensor (not shown), with three sensors that are used for 4 image display devices (level and vertical moving, perhaps two dimension moves).This infrared sensor is installed on the fixed position with respect to mosaic texture 10 and/or mask 11.

This predefined paths is controlled by programmable logic controller (PLC).PLC control mosaic texture 10 or pressing plate move with respect to mask 11, at the mobile round-robin starting point place that is suitable for display device image is correctly aimed at respect to the hole pattern in the mask.PLC also controls mobile graphics itself.Therefore, adjusting part is associated with driven unit.

Pressing plate spare of the present invention is the shape of rectangle substantially, and has when curved forward surface when the cross section is seen and flat rear surface.Pressing plate is made by plastics such as acrylic acid, polycarbonate or glass usually.

Image mosaic structure 10 is installed on the pressing plate, and image mosaic structure 10 is shifted with respect to stacked shadowing mask 11 with pressing plate, so that shelter from some part of mosaic texture 10 selectively, to be provided for the projection by its other parts.The element that pressing plate normally is moved, mosaic texture 10 moves jointly with pressing plate.

Mosaic texture 10 is a rectangle also usually, comprises a plurality of image pixels (as shown in Figure 1) from a plurality of discrete pictures, and these discrete pictures are dispersed in the even figure on the mosaic texture 10, and corresponding to the hole pattern that forms on the mask 11.Thereby mask 11 is placed on the mosaic texture 10, and among both one with respect to another displacement, with hole on the mask 11 and image section registration corresponding to one of them discrete picture that forms on the mosaic texture 10, thus display image.This relatively moving carried out continuously, with the hole on the mask 11 and each group part order registration corresponding to each discrete picture that scatters on the mosaic texture 10.

Mosaic texture 10 is the plastic sheet members that are printed with several mosaic images on it.Mosaic texture 10 is very thin, is complementary with the curved shape that can make sheet material and pressing plate spare front.

As shown in Figure 1, inlaid sheet materials 10 comprises a mating holes 12 within it.Mating holes 12 is set as transparent part, and this transparent part is limited at mosaic texture 10 in the zone of opacity of mosaic image.Zone of opacity is arranged on the bottom of inlaid sheet materials 10, is positioned at outside the image mosaic structure self.

Mask 11 is a rectangle also usually, has thereon opaque grid that forms, and this opaque grid limits the predetermined pattern that the several holes that approximately evenly separates constitutes, and carries out projection with blocking light by about 75% zone of mask 11.The blocking-up character in these holes and shape depend on the number of image in the demonstration and the content of mosaic texture 10.These holes of Fig. 1 are that side edge length is approximately the square of 1mm, although the yardstick in hole and shape can change according to the size of mosaic texture 10 and configuration.

The luminous back lighting of image mosaic structure 10 is passed in mask 11 blocking-up except that passing display aperture.Mask 11 is configured to sheet material spare.

Mask sheet material 11 also comprises at least one mating holes that is positioned at it.And mating holes 13 is arranged to be limited to an interior transparent part of zone of opacity of mask 11.

As shown in Figure 2 each other correctly on time, the mating holes 12,13 of mask 11 and mosaic texture 10 is offset mutually in mask 11 and mosaic texture 10.Mating holes 12,13 is the shape of rectangle.Skew is 12,13 vertical scale in the hole.Each mating holes 12,13 only is displaced to this degree and gets final product, in case promptly hole 12,13 stops mutually vertically to aim at, just not having any light does not penetrate each opaque section that is located on mosaic texture 10 and the mask 11, and does not have light and pass these parts.Thereby this will allow sensor when the position that mating holes 12,13 is no longer aimed at, and establish correct alignment position thus.

Drive unit comprises at least one linear actuators.This linear actuators comprises the step function part, and it has an output shaft, and by means of a sliding component that is suitable for sleeve pipe or railway guidance, this output shaft operationally is coupling on mosaic texture or the mask sheet material.This stepping linear actuators is coupling on the PLC, with mobile in opposite direction output shaft, thereby realizes moving back and forth of sliding component, and this sliding component operationally is coupled to mask 11 or mosaic texture 10 sheet materials.

PLC makes actuator mosaic texture 10 is offset preset distances with respect to mask 11 selectively, thereby with several image sections of one of them discrete picture on the mosaic texture 10 and the several holes registration on the mask 11.In case realize this registration, PLC works drive unit is failure to actuate, so that image can show the time quantum of one section preliminary election.After the time quantum of this preliminary election disappeared, PLC automatically made drive unit can be offset mosaic texture 10 once more, with will be corresponding at the image section of the next discrete picture that forms on the mosaic texture 10 and the hole registration on the mask 11.Continue this order, thereby with the discrete picture on the mosaic texture 10 sequentially with mask 10 on the hole pattern registration.

The predefined paths that is used for mobile mosaic texture 10 comprises alignment stage and mobile phase, guarantee that in this alignment stage mask 11 aims at the correct of mosaic texture 10, in this mobile phase, carry out the predetermined mobile step of mosaic texture 10, to show each image of mosaic texture 10 with respect to mask 11.Alignment stage forms the part of this mobile phase usually.

The alignment stage that should move comprises that mosaic texture 10 is with respect to the moving of mask 11, to establish correct alignment position.The mobile phase of mosaic texture 10 is determined according to the number and the orientation of various images in the mosaic texture 10.For example, if in the mosaic texture 10 three images are arranged, and the skew mutually in the band of vertical orientation of these three images, then should move is that along continuous straight runs linearity (one dimension) back and forth moves.Utilize four picture systems (wherein image can at square figure bias internal), need two dimension to move (level is with vertical).More than one group of mating holes can be set, so that aim at mosaic texture 10 and mask 11 at both direction.

According to a preferred embodiment, the alignment procedures of being undertaken by PLC in 3 image configurations shown is as follows.When starting this device or when the aligning that detects mosaic texture 10 and mask 11 goes wrong, infrared sensor will sense a kind of in the two states, that is:

A) sensor is surveyed the light that passes each hole 12,13 of aiming in mask 11 and the mosaic texture 10.PLC is programmed to when detecting this situation, and the PLC accessory drive moves image mosaic structure 10 along first direction.Along with image moves along first direction, the size of mating holes 12,13 will diminish gradually, up to sensor detect do not have light till, will be suitably no longer corresponding as these holes.It is the correct aligned position of mask 11 and mosaic texture 10 that PLC will suitably be programmed to this is considered as, PLC is then by moving the distance of programming in advance with image towards first direction, with second image is placed as with mask 11 in the hole align, thereby allow it to show, PLC will carry out moving of mosaic texture 10 along predefined paths thus.Subsequently, PLC suitably calculates and turns back to the programming number of center image with the step that allows its demonstration, and in view of the above, it will calculate and turn back to the programming number of left image with the step that allows its demonstration again.Then, PLC advances mosaic texture 10, turns back to correct alignment position, and sensor is being monitored the light that passes each hole of aiming in mask 11 and the mosaic texture 10 simultaneously.When sensor stops to survey the light time of passing these mating holes, PLC suitably with this once more as correct alignment position, and reset.Therefore, in each circulation, can check position and the single part of each image and aiming at of mask 11 of mosaic texture 10, thereby guarantee that image mosaic structure 10 aims at the correct of mask 11.

B) the hole place that detects in mask 11 and mosaic texture 10 of sensor does not have light, PLC will move image along second direction, detect up to it and to pass mating holes and from thereon light, PLC is following accessory drive alignment procedures of describing in above-mentioned (a).

In the example of 2 image display systems or 4 image display systems, routine or circulation can be done variation slightly, but ultimate principle is identical.
