By fan out electric conductor 31, connect liner 33 and can construct enough greatly so that easy connection to them is provided.For example, if the array 15 of the luminescent device 12 of luminescent device display chip 28 comprises 40, the array 15 of the luminescent device 12 of 000 device (for example 200 * 200) and each luminescent device display chip 30 comprises 10,000 device (for example, 50 * 200), each device comprises area of section with one 10 microns and one 20 microns interval P, so the area of the core 13 of optical clear substrate 10 will be less than approximate 0.3 inch in long limit one side.In this specific embodiments, substrate 25 is installed is constructed to have in long limit one side and is approximately 0.3 inch core 27 and is 0.5 inch neighboring in a side.
With reference to figure 4, this figure depict have a separated part be marked by 25 ' the top view of amplification of another embodiment of installation substrate.Be noted that all compositions similar with the composition described among Fig. 1 and 3 are marked by the identical numeral that has added " ' " so that differentiate different embodiment.At least located an optical clear core 27 ', to remove to accept a plurality of luminescent device display chips in the above of describing together with Fig. 3, and, a plurality of electric conductors 31 ' be positioned in install substrate 25 ' first type surface 29 ' go up and from be positioned in core 27 ' the edge a plurality of connection liner 32 ' fannings and be connected liner 33 ' connection.Connect liner 33 ' around core 27 ' first type surface 29 ' on be oriented to the matrix of row and column.Usually, can expect to connect liner 33 ' can be positioned in the matrix so that allow enough space to be used to make conductor 31 ' extend therein as depicted to the spacing in the 50 mil scopes with about 25 mils.For example, have the connection liner 33 of 40 mils ' matrix allow have have in 0.2 inch * 0.4 inch 1 inch * 1 inch the substrate of core more than 500 connect liners 33 '.
In this embodiment, substrate 25 is installed constitutes by glass, at least for electric conductor 31 be connected liner 32 and 33 and can use the scumbling of standard to cover metal, wherein, metal level deposits with for example splash method.In representational metal disposal system, provide the 1st layer of chromium so that play the effect of adhesive linkage on glass by splash.On whole of chromium, provide the 2nd layer of copper so that desirable electric conductor is provided, on the face of whole copper, provide a metal level so that the adhesive linkage that a potential barrier is provided and is used for further connecting.Certainly, the metal processing can be to have the pattern method of any method formation of various methodologies known in the past technology and the interpolation or the minimizing method of etching method, so that desirable final structure is provided.
In many application, perhaps electric conductor width and pad size and gap especially will meet difficulty for substrate in assembling.In a word, glass is an example of optical clear base material, can assemble 10 to 15 microns wide electric conductors with 40 micron pitch in the above.
With reference to figure 5-7, these figure provide briefly is preferential embodiment for the structure of the luminescent device display chip 28 in light of the present invention-electric parts and 30.As Fig. 5-7 describes, have multiple structure for luminescent device display chip 28 in described light-electric parts here and 30 layout.Generally, have a basic luminescent device display chip, be labeled as 28 here, can launch a high-resolution picture or complete image, also has an additional luminescent device display chip 30, can launch with the low or different resolution of resolution than main light emission device display chip 28, the configuration structure of the pool images that produced by luminescent device display chip 28 and 30 according to hope carries out layout.Especially, be positioned at by the high-resolution main demonstration of luminescent device display chip 28 generations or a side of complete image if wish menu or target bar, then luminescent device display chip 30 is positioned in two relative sides as shown in Figure 5.If wish to be created in a high-resolution main side that shows to one such as the many menus of multiple color or the image of target bar, then luminescent device display chip 28 and 30 will be positioned in light of the present invention-electric parts as shown in Figure 6.For example surround high-resolution main menu or the such image of target bar that shows that is generated by luminescent device display chip 28 fully in order to produce, then luminescent device display chip 30 should be shaped as shown in Figure 7.Obviously, depend on the size, position, color, resolution and the quantity that are shown image,, have unlimited many possibilities for the luminescent device display chip 28 and 30 in structure light of the present invention-electric parts.
Described among Fig. 8,9 and 10 according to scenography drawing light- electric parts 50,50 ', 50 " the exploded view of each several part relative position.Described among Figure 11 the general separated part identical with the each several part of Fig. 9 be assembled to a complete light-electric parts 50 ' in enlarged drawing.Described among Figure 12 the general separated part identical with each several part among Figure 10 is assembled to a complete light-electric parts 50 " in enlarged drawing.Cause concern once more, all same sections of the disclosed embodiments have " ' " or " " of interpolation with identical numerical reference " be to be used to distinguish different embodiment.Therefore,, be applied on the identical component of preferential embodiment for the description of the composition of an embodiment about Fig. 8-12, that is, the description that substrate 25 is installed also be applied to install substrate 25 ' and 25 ", unless in addition by note.
Particularly with reference to figure 8,9 and 11, remove outside optical clear substrate 10 and the installation substrate 25, also comprise a driver substrate 55, this drives association's device substrate 55 has the interarea of one the 1st interarea and one the 2nd opposition and is installed in a plurality of drivers and control circuit 57 on the 1st interarea, and this driver substrate 55 has determined that also a reality is with the central area of being expanded by the complete image of the 1st luminescent device display chip 28 and luminescent device display chip 30 generations that at least one is additional.A plurality of drivers and controller circuitry 57 generally constitute as Small Scale Integration; their lines connect or multimodal connects (bump bonded) so that be electrically connected on the 1st interarea of driver substrate 55, and the 1st interarea of driver substrate 55 has the spherical top structure that is used to protect driver and control circuit 57 that forms in the above.Driver substrate 55 for example is a suitable printed circuit board (PCB), such as FR
4Deng, and have as C
5Scolding tin is such can plated metal etc. the peak (bump) 58 of connection material, perhaps be positioned at the connection pin (pin) 59 on the interarea of the 2nd subtend.Because the spacing that the connection liner 33 in the substrate 25 is installed relatively (or can relatively) is bigger, therefore, can use bigger peak 58 or pin 59 on these aspects.
The material that constitutes peak 58 is an electric conductor and can partly dissolve and be re-set as at least and constitute good physical connection preferably.The material that can be used in this purpose comprises gold, copper, scolding tin particularly high temperature scolding tin, conductive epoxy etc.Height greater than 80 microns peak energy enough be formed on one pros or have on the connection/installation liner of the circle of 20 micron diameters.For less spacing, the copper lining with 5 micron diameters of 10 micron pitch is configured as 20 microns liner height.In addition, the peak of 15 micron diameter gold on 30 micron pitch is configured as 30 to 45 microns height.Some compatible metal can improve assembling process, and for example, the deposit on the connection liner 33 of optical clear substrate 10 is handled or be gold-plated.
In assembling process, as Fig. 8 and 9 described, correctly overlap on time when substrate 25 is installed, install substrate 25 be oriented to interarea 29 upwards and also connection liner 33 be oriented to each and all be connected independent peak 58 or connection pin 59 in the driver substrate 55.In a kind of mounting technology, installation substrate 25 comprises the connection liner 33 of gold and is received in the driver substrate 55 by thermocompression bonded.
Driver substrate (general identical) during with reference to Figure 10 and 12, what describe is light-electric parts 50 ", these parts have directly to be installed to installs substrate 25 " on driver and control circuit 57 ", and no longer needs to be included in light-electric parts 50 " with driver substrate 55.In this particular example; driver and control circuit 57 " connected or peak link substrate 25 is installed " interarea 29 by line " on electric connector (not shown); on the other hand; disclose among the figure in that substrate 25 " surface on driver and control circuit 57 " is installed and be installed in to subtend the both sides of luminescent device display chip 28 and 30; use guiding frame (leadframe) that is embedded into and/or the via path (not shown) that plates in this embodiment luminescent device display chip 28 " with 30 " and driver and control circuit 57 " electric connection; also disclose among the figure on driver and the control circuit 57 " be directly mounted to install substrate 25 ", this is in order to use dome establishing protective driver and the control circuit 57 " and luminescent device display chip 28 " and 30 as the standard of having known in the prior art "
Install under the situation of substrate 25 described having finished practically of Fig. 8-10, installation substrate 25 can easily be tested before the additional assembling of parts and/or be aging.This ability of a semipilot point that provides can be saved a large amount of costs and time in encapsulation process.
Light- electric parts 50,50 ' and 50 " in final additional composition be lens 60, as shown in Figure 8, these lens 60 are installed into and cover the top and relative with luminescent device display chip 28 and 30 of the core 13 installed in the substrate 25.In another embodiment and as Fig. 9 and 10 described, lens 60 are with compression molding forming (transfermolding) or injection molded the time, be integrally formed in the core 27 that substrate 25 is installed, and practically with enlarging by luminescent device display chip 28 and the 30 complete images of combination that generate.Lens 60 are designed to amplify the complete image that is produced by at least 2 arrays 15 that are formed on luminescent device display chip 28 in the optical clear substrate 10 and 30 luminescent device 12.As shown in Figure 8, lens 60 are attached to the downside that substrate 25 is installed by some suitable optical clear epoxy resin, the projection that easily cooperates and the space of matching etc., and are assembled on the core 27 that easily is pressed in installation substrate 25.
With the space (as shown in figure 10) between a kind of optically transparent material 63 filling driver substrates 55 and the installation substrate 25 mounted thereto, this material 63 can provide supporting and light-electric parts 50 and 50 ' make any suitable material of firmer parts.Depend on the material that uses in the structure of luminescent device display chip 28 and 30, can in driver substrate 55, form a hohlraum (as shown in figure 11) with hold chip 28 and 30 and the edge of chip 28 and 30 can be oriented to fully near driver substrate 55 to make that the upper surface of chip 28 and 30 and the gap between the driver substrate 55 are opened wide or not filling so that play the effect of a similar barrier.Thereby luminescent device display chip 28 is not physically to be attached to together and to have very little different expansion coefficient or a not influence with 30 with driver substrate 55.
Self-evident, for the installation substrate 25 of optimum efficiency, optically transparent material 63 and lens 60 use various refractive indexes and construct, and they are close mutually in actual applications.If the refractive index that substrate 25, optically transparent material 63 and lens 60 for example are installed is in fact inequality, then exist the tendency that the efficient at the light that reflexes to luminescent device display chip 28 and 30 at the interface and light-electric parts 50 is reduced.Generally, for substrate 25, optically transparent material 63 and lens 60 are installed, find that approximate 1.5 refractive index is acceptable.
Self-evident, too small by the complete image that the array of the luminescent device 12 that the luminescent device display device in the substrate 25 is installed produces, thus the eyes of personnel selection can not carefully watch (understanding fully) and be typically light and complete watch need at least 10 multiplying powers amplification.Lens 60 can be that single lens or the lens 60 with the auxiliary optical magnification that is provided by external system can comprise a complete amplification system.And then, lens 60 can with glass, plastics or arbitrarily other material and in optical technology known skilled method manufacture.In addition, in some applications, lens 60 can be outside completely amplification systems and can not physically connect as the part of light-electric parts 50, perhaps are formed on and install in the substrate 25.Described to merge in the lens 60 or supply to the optical amplification system of lens 60 from the outside or some examples of lens combination among Figure 13 to 15, described below.With reference to Figure 13, this figure has described the virtual image display 65 of an embryo with the sketch map of simplifying.Embryo virtual image display 65 comprises visual generation equipment 66, with light described above- electric parts 50,50 ' and 50 " identical, be used on a surface 67, providing the image.Optical system describing with lens 70 and 67 location spaced apart, surface of embryo virtual image display 65 and produce the virtual image of available eyes 71 from watching from a distance by lens combination 70 definite apertures.
As reducing light-electric parts and/or being included in the technology of the size of luminescent device wherein, need bigger magnification and less lens combination.
Optical amplification system or the lens combination 70 described with 1 lens simply are installed in respect to surperficial 67 a distance so that receive from the image on surface 67 and additional predetermined amount of this zooming.Certainly, lens combination 70 can be adjusted for the poly-and additional magnification of Jiao, if desired, and perhaps in order simply to be fixed on the shell.Because the images that received from surface 67 by lens combination 70 are much larger than the image that is taken place by image generation equipment 66, so lens combination 70 do not provide whole magnifications, and is configured to big and has less magnification.Because this bigger size, lens combination has a bigger viewing areas and a bigger operating distance.
What carry out the eyes adjusting is such segment distance, and eyes 71 can be with watching 72 location, aperture and still can intactly watching image, and this distance is described with " d " in Figure 11.Because the size of lens combination 70, eyes are regulated or be fully apart from d for comfortable watching is provided, and this distance is enough big so that under the situation of hope in the present embodiment, and the permission beholder wears the glasses of standard.Owing to improved the eyes adjusting, so the operator can wear the correcting lens (individual glasses) of standard, and can reduce focus on and other adjustable can complicacy, therefore, simplified the structure of embryo virtual image display 65.
With reference to Figure 14, this figure has described another kind of blank virtual image display with simple form.In Wavequide virtual image display 80, with light described above- electric parts 50,50 ' and 50 " input end that identical image generation equipment 81 is installed in optical waveguide 82 is used for a complete image is provided to optical waveguide 82.Optical waveguide generally constitutes to have and equates and the shape shape (side-looking) of the parallelogram of limit 83,84 that parallel group of adjacent edge off plumb is relative and 85,86.Input end has been determined on limit 83, and usually along the light-path of being determined by whole 4 limits the light ray from the complete image of image generation equipment 81 is directed into a presumptive area on the adjacent side 86.84,85 and 86 have located 3 diffraction lenss 87,88 and 89 respectively 3 presumptive areas along adjacent limit, and 85 output terminal can be watched the virtual image that has amplified on the limit.This specific embodiments has been described a display, has reduced some overall dimensions in this display and has reduced the quantity of material in the waveguide so that weight and employed material are reduced to minimum.
With reference to Figure 15, this figure has described another special blank virtual image display with simple form.In Wavequide virtual image display 90, used one to have with the general leg-of-mutton optical waveguide 91 that is shaped of edge height.Be used to produce a complete image, with above-mentioned light- electric parts 50,50 ' and 50 " identical image generation equipment 92 is installed on the 1st limit 93 of optical waveguide 91 and radiation directly propagates into light ray on the diffraction lens 94 that is installed on the 2nd limit 95 along light path.Light ray is reflected on the diffraction lens 96 that is installed on the 3rd limit 97 from diffraction lens 94.Transmission 96 is the reflected light ray successively, makes light ray by being installed in limit 93 and being fixed to the final diffraction lens 98 of the output terminal of optical waveguide 91, and this diffraction lens 98 has determined that for Wavequide virtual image display 90 is watched an aperture.In this specific embodiments, the limit of Wavequide virtual image display 90 is location, an angle ground mutually, thereby input end and output terminal are at right angles imported and leave to light ray respectively.
With reference now to Figure 16,17 and 18,, these figure are respectively with front view (FV), and side front elevation and top view illustrate corresponding to another embryo virtual image display 100 of the present invention.Figure 16,17 and 18 has been provided by the expression of embryo virtual image display 100 to provide one to reduce limit as the size aspect that is reached by the present invention near physical size.Embryo virtual image display 100 comprise one generally with light of the present invention- electric parts 50,50 ' and 50 " identical integrated light-electric parts 102.In preferential embodiment, integrated light-electric parts 102 produce an approximate brightness less than 15fL, because embryo virtual image display 100 produces a virtual image, so this low-down brightness is possible.Integrated light-electric parts 102 are installed in the lens combination 104, this system zooming nearly 20 times so that produce the virtual image of approximate 8.5 " * 11 " scraps of paper.
Be noted that here because integrated light-electric parts 102 are very little and in fact use virtual image, rather than a direct viewing shows, thereby whole physical sizes of embryo virtual image display 100 be approximately 1.5 inches (3.8cm) wide * 0.75 inch (1.8cm) high * 1.75 inches (4.6cm) dark, perhaps cumulative volume is approximately 2 cubic inches of (32cm
3).
With reference to Figure 19, for the sake of clarity, this figure has described to amplify the side front elevation of embryo virtual image display 100 of Figure 14 of 4 times.Can see on the upper surface that the 1st optical lens 106 directly is installed in installs substrate 107 (usually identical with installation substrate 25) from this view.An optical prism 108 is installed so that reflect from the image on a surface 110 and therefrom by a plane of refraction 112.So image is directed into the optical lens 114 with a refraction input face 115 and a refraction output face 116.From optical lens 114, image is directed into the optical lens 118 with an input plane of refraction 119 and an output plane of refraction 120.Also have, in the present embodiment,, for example provide at least 1 diffraction optical device on face 110 and/or the refraction input face 115, to remove to correct aberration etc. at a face.The operator sees into and will see a big virtual image that is easy to distinguish that this image is as the back at embryo virtual image display 100 from the output plane of refraction 120 of lens 118.
Figure 20 shows a portable electron device with data outlet terminal (not shown), just has a portable communication receiver 130 of embryo virtual image display 132 being installed handheld microphone 131 within it.Self-evident, this portable communication receiver 130 can be any known portable communication device, for example honeycomb or wireless phone, twoway radio, pager, database or the like.In the present embodiment, only be used for illustrative purposes, portable communication receiver 130 is that a portable two-way police uses radio set, normally police officer's type of carrying when on duty or security guard.Portable communication receiver 130 comprises that is used for the control panel 134 of active call and if desired, also has a visual displays 136 that is used to show the standard of called numeral or digital call.On the other hand, 136 comprise one except visual displays or the loudspeaker of alternative visual displays.Handheld microphone 131 has a press to talk switch 138 and an acoustic pickup 140.
With reference to Figure 21, this figure has described the simplification sectional view of looking to handheld microphone 131 from line 21-21.Embryo virtual image display 132 comprise one with above-mentioned light- electric parts 50,50 ' and 50 " identical light-electric parts; have the image generation equipment 141 that is used for a complete image is offered the optical system 142 that is fixed, this optical system 142 produces the virtual image that an operator can watch by aperture 144 successively.The optical system 142 that is fixed is configured to amplify the whole complete image from image generation equipment 141, and do not use movable part, thereby be complete frame or photo by the virtual image that aperture 144 can be watched, they seem very big (the normally size of a printer paper) and are easy to be distinguished out by the operator.Overall optical-electric parts are less and require no added space (no additional space requirements) to be added in the handheld microphone 131 practically.Optical system 142 is configured to have non-moving part, is different from such as assembling opticses such as Jiao, amplifying lens.And then handheld microphone 131 needs very little electric power to remove to produce complete image, thereby very little power is added on the power requirement of portable communication receiver 130.
With reference to Figure 22 and 23, this figure has described the 2nd embodiment, and wherein, the part identical with the part of describing in Figure 20 and 21 is with identical numeral and add numercal " ' " mark to so that distinguish different embodiment.In the present embodiment, one of portable communication receiver 130 ' have be included in blank virtual image display 132 in the main body ', thereby replace among handheld microphone.Handheld microphone be selectable and also this specific embodiments for do not use or inapplicable handheld microphone and the equipment do not launched for pager etc. in situation about using be satisfied.Identical and the communication control processor 130 of embryo virtual image display 132 in embryo virtual image display 132 ' basically and Figure 20 and 21 ' size, weight or power consumption increase are seldom.
