DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 1A illustrates a three-dimensional (3D) display assembly according to an embodiment of the present invention. The display assembly comprises a plurality of illumination devices (e.g., see FIGS. 4A and 4B) arranged in a three-dimensional (3D) array 100. The 3D array structure 100 may, for example, be conceptually organized into a plurality of planes 102, such as planes x₁ z ₁ 104, x₂z₂ 106, x₃z₃ 108, and x_nz_n 110, which have been stacked along a Y-dimension 112.
FIG. 1B schematically depicts plane 104 (i.e., x₁z₁) within the 3D array of illumination devices 100 (FIG. 1A) according to an embodiment of the present invention. A plurality of illumination devices, such as a 3×3 configuration of illumination devices, are positioned in plane 104, as shown in FIG. 1B. Each illumination device 118 includes a first conductor 120 and a second conductor 122. Each first conductor 120 comprises a first contact 119 (e.g., +ve contact), and each second conductor 122 includes a second contact 123 (e.g., −ve or ground contact). The first conductor 120 associated with the illumination devices are interconnected and coupled to an address line conductor 121 a. The second contact 123 associated with the illumination devices in the plane are, however, not interconnected, and are separately controlled.
For example, by applying a first electrical signal (e.g., +ve voltage signal) to address line conductor 121 a of plane 104, the first conductor 120 and first contact 119 associated with all other illumination devices within plane 104 (i.e., x₁z₁) will also receive the electrical signal. Once the first electrical signal is applied to the devices in plane x₁z₁, which in a sense enable each device in the x₁z₁plane, application of a second electrical signal (e.g., −ve voltage or grounding) to any individual illumination device will activate that illumination device.
An illumination device 118 may comprise, for example, a light emitting diode (LED), a liquid crystal display (LCD), and/or any other material capable of generating a visual characteristic (red, green, or blue light, or combinations thereof) upon receiving one or more electrical signals. For example, once the first conductors 120 of devices 124 in plane 104 receive the first electrical signal, they become enabled, and upon application of the second electrical signal (e.g., negative voltage or ground) to the second conductors 122, a respective device or devices are activated and provide a visual characteristic, e.g., light.
FIG. 1C schematically depicts planes 104 (x₁z₁), 106 (x₂z₂), and 108 (x₃z₃) within the 3D array of illumination devices 100 (FIG. 1A) according to an embodiment of the present invention. FIG. 1B illustrates the interconnectivity between the illumination devices within each plane, while FIG. 1C illustrates the common connectivity configuration between illumination devices of adjacent planes, e.g., orthogonally positioned. For illustrative purposes and to avoid overcomplicating FIG. 1C, only the connectivity between the first three planes 104, 106, 108 of array 100 (FIG. 1) is shown. For example, as illustrated in FIG. 1C, the second conductor 122 a associated with illumination device 124 is connected to corresponding second conductor 122 b associated with illumination device 126, which is also connected to second conductor 122 c associated with illumination device 128. Thus, illumination devices 124,126, and 128, which are orthogonally positioned with respect to the planes 104, 106, 108, comprise interconnected second conductors 122 a, 122 b, and 122 c.
For example, applying an electrical signal to address line conductor 130 a provides the electrical signal to the second conductors 122 a, 122 b, 122 c associated with illumination devices 124, 126, and 128. Similarly, applying an electrical signal to address line conductor 130 b provides the electrical signal to the second conductors associated with illumination devices 132,134, and 136, and applying an electrical signal to address line conductor 130 c provides the electrical signal to the second conductors associated with illumination devices 138, 140, and 142. For example, in order to activate devices 126 and 134, which are located at plane 106, a first electrical signal (e.g., +ve voltage) is applied to address line conductor 120 b and a second electrical signal (−ve voltage or, ground) is applied to column address line conductors 130 a and 130 b. As previously described, application of the first electrical signal to address line 120 b provides the first electrical signal to all first conductors 125 of the illumination devices in plane 106. However, in order to activate an illumination device in plane 106, a second electrical signal is provided to the column address line (e.g., 130 a, 130 b, 130 c) for that illumination device in plane 106.
Although the plurality of planes illustrated in FIG. 1A are shown to be substantially horizontal, the planes may be conceptually organized according to how a user of the 3D display assembly intends to operate or activate the array of illumination device 100. For example, a plane may be configured to run along the yz-plane, where each of the designated yz-planes may be stacked along the x-dimension. Also, the concept of planes described according to various aspects of the present invention is for purposes of illustrating the physical positioning and operation of the illumination sources within the 3D display, and may not be limited to any particular physical plane or surface.
FIGS. 2A and 2B are perspective views of the first conductor 120 and the second conductor 122 as depicted in FIG. 1B, according to an embodiment of the present invention. First conductor 120 comprises a first tab or arm 206 and a second tab or arm 208 separated by a portion of an intermediate section 210 extending from point A to point B. First conductor 122 also comprises a third tab 212 and a forth tab 214, which is also separated by a portion of intermediate section 210 extending between points C and D. The portion of intermediate section 210, which is common to both the first and second tabs 206, 208 and the third and fourth tabs 212, 214 is designated by region F. Region F includes first contact region 119 for receiving one or more conductive pins associated with a device such as light emitting diode (see FIG. 3B). In addition to an electrical device such as a light emitting diode (LED), other devices that visually react to electrical signals may also be coupled to contact 119. For example, a material that reacts to electrical current, voltage, and/or any electromagnetic signal (e.g., light) may be incorporated within the 3D display system by being coupled to contact 119. Contact 119 may be located along any portion of intermediate section 210. For example, contact 119 may be position anywhere between points A and B, or between points C and D. Conductors 120 and 122 are shown as being substantially horizontal and vertical, respectively. Conductors 120 and 122 may, for example, have various other orientations with respect to one another, provided, each of the conductors 120, 122 are electrically isolated from each other.
Second component 122 comprises first tab or arm 218 and second tab or arm 220, where both tabs are separated by intermediate section 222. Intermediate section 222 includes a second contact 123 for receiving one or more of the other conductive pins associated with the LED or other optical device, where the LED or device may be attached between contacts 119 of conductor 120 and contact 123 of conductor 122. Thus, the optical device (e.g., LED) may be activated by receiving electrical signals on contacts 119 and 123. Contact 119 may receive an electrical signal via any one of tabs 206, 208, 212, or 214. Similarly, contact 123 may receive an electrical signal via any one of tabs 218 or 220.
Tabs 206, 208, 212, and 214 each comprises an end portion 213, which may be connected to the tabs of other first conductors. Similarly, each of tabs 218 and 220 also comprises an end portion 215 for connecting the tabs to other tabs associated with other second conductors. For producing a three-dimensional display, different connectivity methods may be employed for connecting the end portions of the tabs associated with the first and second conductors. For example, the end portions of the tabs may have complementary connectors that couple together according to known methods, or alternatively, they may be soldered. The connectivity means should however provide an electrically conductive connection between the interconnected tabs.
The intermediate section 210 illustrated in FIG. 2A may be any suitable shape and is not limited to the exemplary embodiment illustrated. For example, section 210 may comprise a substantially square, rectangular, triangular, and/or multisided shape. It may also be possible for conductor 120 to not have intermediate section 210. In such an embodiment, tabs 206 and 208 extend toward each other to form a single arm or tab. Similarly, tabs 212 and 214 may extent toward each other to also form a single tab. Thus, component 120 may form a cross like shape based on the intersection of tabs 212, 214, 206 and 208. If first component 120 is formed in such a manner, intermediate section 222 (FIG. 2B) of second conductor 122 may be required to comprise some form of shaping in order to avoid any contact with conductor 120, since these conductors may be required to be electrically isolated when forming an illumination device assembly (see FIG. 3A). Current illustrations provide a symmetrical device assembly, where an illumination source (e.g., light emitting diode) may be connected in the center of the assembly. However, components 120 and 122 may also be adapted to form a less symmetrical assembly, or one without symmetry.
For example, in an alternative embodiment, in addition to the intersection of tabs 212, 214, 206 and 208 (FIG. 2A) of first conductor 120 forming cross shape arms 250 (FIG. 2C), tabs 218 and 220 of conductor 122 (FIG. 2B) may also extent toward each other to form a single arm or tab 252 (FIG. 2C). As illustrated in FIG. 2C, the cross shaped first conductor 250 comprises a first contact 254 for receiving a one or more conductive pins or terminals of an illumination source or optical device (not shown). Conductor 252 also comprises a second contact 256 for receiving one or more other conductive pins or terminals associated with the illumination source or optical device.
FIGS. 3A and 3B are perspective views of an illumination device assembly comprising the first and second conductors 120, 122 depicted in FIGS. 2A and 2B according to an embodiment of the present invention. As illustrated in FIGS. 3A and 3B, opening 226 (FIG. 2A), which is located between tabs 206 and 214 of first conductor 120 (FIG. 2A), provides a means for positioning second conductor 122 (FIG. 2B) with respect to conductor 120, such that contacts 119 and 123 are aligned in manner that enables them to receive an illumination source or optical device such as an LED 302.
As illustrated in FIG. 3B, first conductor 120 comprises intermediate section 210. The intermediate section 210 includes first contact 119 for connecting to one or more contacts associated with the illumination source or optical device. From the intermediate section 210, the first pair 206, 208 and second pair 212, 214 of tabs extend outwardly with respect to intermediate section 210, where the first and second pair of tabs 206, 208, 212, 214 are spaced about the periphery of intermediate section 210. Second conductor 122 comprises second intermediate section 222, where intermediate section 222 includes second contact 123 for connection to one or more other contacts associated with the illumination source (e.g., LED 302). Intermediate section 222 also comprises a third pair of tabs 218, 220 extending outwardly in opposite directions. Conductors 120 and 122 are positioned relative to each other such that contact 119 and 123 are aligned with the pin or terminal connections of LED 302. As illustrated, conductors 120 and 122 are also positioned in substantially orthogonal planes with respect to each other. The intermediate sections 210, 222 of the conductors 120, 122, and their respective positioning, provides electrical isolation between the conductors 120, 122 based on their physical separation.
First and second conductors 120 and 122 convey signals to their respective contacts 119, 123 for activating devices (e.g., optical device) that are coupled between these contacts 119, 123. Therefore, the conductors 120, 122 may comprise any material capable of guiding one or more signals to the device that is attached to the conductors. For example, the conductors 120, 122 may comprise any varying degree of conductivity, such as a conductive, semi-conductive, or insulator type material. For example, based on the use of glass or plastic insular material in the construction of the conductors 120, 122, optical sources (e.g., LED or Laser) may be used to transmit the signal to an optical device (e.g., a light reactive surface) coupled to the contacts of these conductors 120 and 122.
FIGS. 4A and 4B each illustrate a perspective view of the illumination devices depicted in FIGS. 3A and 3B according to an embodiment of the present invention. The illumination devices comprise a casing 306,308 for providing a visual effect (e.g., diffusing light) based on light that is generated by the LED 310, or any other suitable illumination source. As illustrated in FIG. 3A, casing 306 may comprise a semi-spherical shaped casing for diffusing light that is generated by LED 310. The semi-spherical shaped casing 306 may be coupled to tab 220. Alternatively, casing 306 may also be coupled to tabs 218, 206, 208, 212, or 214. Similarly, as shown in FIG. 3B, casing 308 comprises a spherical shaped casing, which may also diffuse light that is generated by LED 310. Spherical shaped casing 308 may be comprised of two semi-spherical shaped casings 312, 314 that are coupled to tabs 218 and 220, respectively. Alternatively, the two semi-spherical shaped casings 312, 314 may also be coupled to tab pair 206 and 208, or tab pair 212 and 214.
FIG. 5 is a perspective view of a plurality of illumination devices arranged in a 3×3 plane 500 according to an embodiment of the present invention. As previously described, and illustrated in FIG. 5, the tabs or arms 206, 208, 212, 214 associated with each illumination device that is located in plane 500 are interconnected. For example, section 214 of device 502 is coupled to section 212 of device 504; and section 206 of device 504 is coupled to section 208 of device 506. Since the tabs associated with the illumination devices are electrically conductive, applying an electrical signal to any of the tabs (e.g., tabs 208 or 212), will provide the applied electrical signal to all the other tabs associated with the plurality devices in the plane 500.
FIG. 6 is a perspective view of a three-dimensional display 600 comprising a plurality of planes of illumination devices 602, 604, 606 according to an embodiment of the present invention. As illustrated, each plane (e.g., plane 602) is orthogonal with respect to its adjacent plane (e.g., plane 604). FIG. 6, among other things, illustrates the interconnectivity of multiple planes of illumination devices. For example, within vertical column 605, tabs 218 and 220 associated with illumination devices 608, 610, and 612 are interconnected. Similarly, all illumination devices within other vertical columns are also interconnected by the tabs associated with their second conductor 122 (FIG. 2B). As previously described, the second conductor and its respective tabs are electrically conductive. Therefore, for example, applying an electrical signal to tab 220 of device 608, also provides the electrical signal to sections 218 and 220 of devices 610 and 612 within vertical column 605.
FIG. 7A illustrates a block diagram of a display system 700 according to an embodiment of the present invention. Display system 700 may comprise a computer 702, a controller device 704, and a three-dimensional (3D) display 706, such as, but not limited to, the 3D display assembly 600 illustrated in FIG. 6. Computer device 702 receives image files from, for example, local memory 708 associated with computer 702, a local database 710, and/or one or more remotely located databases 712 that may be accessed via a website 714 over the internet. Image data may also be received by computer 708 from one or more cameras 716, where the cameras may generate still image data (e.g., JPEG, TIFF, GIF, BMP etc.) of motion picture image data (e.g., MPEG). A suitable user-interface or application program (not shown) residing on computer 708 enables a user to select any desired image from one or more of the image sources (e.g., local memory, remote database, etc.) in communication with the computer 702. The program may then facilitate the transfer of the selected image to controller device 704, where the controller 704 processes the image data in order to map this data to corresponding locations (i.e., addresses) associated with the illumination devices within the 3D display 706.
The block diagram shown in FIG. 7B is similar to FIG. 7A, except that the controller device 704 may retrieve and receive image data directly from the image sources such as, for example, the local database 710, the one or more remotely located databases 712, and the one or more cameras 716. The retrieved and received data may then be processed and displayed on 3D display 706 according to various aspects of the present invention.
FIG. 8 illustrates a block diagram of the controller device 704 incorporated within the display system of FIGS. 7A and 7B according to an embodiment of the present invention. Controller 704 may comprise memory 802, an input unit 806 for receiving image data, a microprocessor 804 for processing image data that is received from input unit 806 and/or memory 802, a shift register unit 808 for providing electrical signals to the illumination devices within the 3D display, and a connector 810 for coupling the electrical signals to the 3D display. Connector 810 may comprise a plurality of conductors 812 that are coupled to each plane (e.g., FIG. 6, plane 606) and vertical column (FIG. 6, plane 605) within the 3D configuration of illumination devices (e.g., FIG. 6, display 600).
FIG. 9 is a perspective view illustrating an example of the connectivity between the plurality of address line conductors 902 associated connector 810 of the controller (FIG. 8) and a single plane of illumination devices 904 within a display according to an embodiment of the present invention. The plurality of conducts 902 may be coupled to the plane of illumination devices via a connector 906 associated with the 3D display. As illustrated, a single address line conductor 910 may, for example, be used to provide an electrical signal (R₀) to all the illumination devices in plane 904, since the first conductors 120 (FIG. 2A) of each of the illumination devices are interconnected. The second conductors 122 associated with the illumination devices each individually receive an electrical signal and may not be interconnected within the same plane. Each second conductor 122 and single interconnected first conductor 120 within plane 904 is controlled by an independent address line conductor that is electrically driven by a single output element (e.g., D-type flip-flop) of the shift register unit 808 (FIG. 8, elements D₀-D_n). For example, address line 910 drives conductor 120, and, address lines 916 and 918 electrically drive conductors 122, which are designated by C₀and C₁respectively. In order to avoid overcomplicating FIG. 9, the remaining second conductors 122 and their respective address line conductors have not been labeled with reference numerals. Each conductor from connector 906 is, however, illustrated as connecting to its respective second conductor 122.
For example, a 3D display having a plurality of planes of illumination devices, such as plane 904, will each have a single conductor for providing an electrical signal to their interconnected first conductors 120. However, the second conductors 122 within plane 904 each individually receive an electrical signal from an individual address line conductor (e.g., C₀).
FIG. 10 illustrates a flowchart associated with addressing the illumination devices in the 3D display assembly according to an embodiment of the present invention. The flowchart will be described with the aid of FIGS. 6, 7, and 8. At step 1002, the location of each illumination device is provided with a designated address, which identifies its physical location within the 3D display 600 (FIG. 6). Based on the addresses, the processor 804 (FIG. 8) may provide a series of control signals to the shift registers 808. The shift registers 808 may then electrically drive a corresponding set of conductors that are coupled to the addressed illumination devices via connector 810 (FIG. 8). For example, a corresponding set of conductors may carry electrical signals to column 605 (FIG. 6) and planes 602 and 604 (FIG. 6) of the display 600 (FIG. 6) in order to activate the optical devices or illumination sources within illumination devices 608 and 610, respectively. As previously described, multiple illumination devices may be activated within each single plane in order generate a multitude of three-dimensional visual effects known in the art of animation, visual image construction, and graphics. Referring to FIG. 6, for example, by activating the illumination devices within rows 616 and 618 of plane 606 three-dimensional depth information may be provided for generating a desired 3D visual image.
At step 1004, the controller 704 (FIG. 8) receives image data from either input module 806 or memory 802. The image data may be in any graphics-based still or moving image data format. The processor may be programmed to receive and process these variable data formats according to whether the image data is a two-dimensional still image or picture, a series of animated graphics, video images from one or more camera feeds, and/or based on customized programming loaded into the processor 804 for generating a custom designed image in two or three-dimensional form on the 3D display 600 (FIG. 6). At step 1006, the image data is mapped to the plane/column address locations associated with the illumination devices. This mapping may be carried out by processor 804 (FIG. 8) based on the received image data. For example, the mapping may be carried out by assigning data corresponding to each pixel or group of pixels within an image of a corresponding address location associated with any illumination device within the 3D display 600 (FIG. 6). At step 1008, based on this mapping, corresponding illumination devices are activated in the display 600 (FIG. 6) by applying the appropriate signals to the plane/column locations via the shift register unit 808 (FIG. 8) and connector 810 (FIG. 8).
3D depth information may be added as an additional visual effect by the processor 804 (FIG. 8) based on, for example, a received 2D image. Alternatively, the image data may already comprise 3D data, where the mapped data is applied to the appropriate address location within the display 600 (FIG. 6). Also, for example, images generated from two cameras may generate 3D image data for generating a 3D visual display. A first camera may, for example, generate images in an XY coordinate system, while a second camera generates ZY coordinate information for providing depth information to the XY coordinate images. Corresponding XYZ data information from these cameras may then been mapped by the controller 704 (FIG. 8) for generating a 3D display.
FIG. 11 illustrates a circuit diagram of a controller device 1102 associated with the display system according to an embodiment of the present invention. The controller device 1102 comprises a plurality of shift registers 1104 and a microprocessor device 1106 (i.e., PIC 16F874P chip), whereby microprocessor 1106 controls the shift registers 1104.
FIG. 12 is a schematic diagram of a 3D display for creating visual display information based on receiving electrical signals in a scanned manner according to an embodiment of the present invention. FIG. 12 illustrates three planes P1, P2, P3, from a plan view perspective, each comprising four illumination devices. For example, plane P1 includes illumination devices A, B, C, and D; plane P2 includes illumination devices A′, B′, C′, and D′; and plane P3 includes illumination devices A″, B″, C″, and D″. FIG. 12 illustrates the electrical connectivity between the device within each of the planes, the connectivity between the planes themselves, and the electrical connectivity associated with the address line conductors that are coupled to the illumination devices. In order to avid over complicating the figure, three planes of a 2×2 array of illumination devices are shown. Based on the application and resolution requirements of the display, P planes of an N×M array may be created, where N=M or N ≠M, and N, M, and P are a positive integer (i.e., ≠0).
Within each plane the first conductors 120 of all the illumination devices are interconnected and coupled to an address conductor that provides an electrical signal to all the illumination devices within the plane. For example, within plane P1, the first conductors 120 of devices A, B, C, and D are interconnected and coupled to address line conductor AD1. Also, within plane P2, the first conductors 120 of devices A′, B′, C′, and D′ are interconnected and coupled to address conductor AD2. Similarly, within plane P3, the first conductors 120 of devices A″, B″, C″, and D″ are interconnected and coupled to address conductor AD3.
Also, the second conductors 122 of all individual illumination devices within each plane are interconnected to all other second conductors 122 of illumination devices within other planes that are within a vertical column. For example, the second conductors 122 of illumination device A of plane P1 is interconnected to the second conductors 122 of illumination devices A′ and A″ of planes P2 and P3, respectively. The interconnected second conductors 122 of illumination devices A, A′ and A″ are coupled to address conductor C1. This interconnection between the devices A, A′, A″ and address line C1 is illustrated by dashed line 1202.
Also, the second conductors 122 of illumination device B of plane P1 is interconnected to the second conductors 122 of illumination devices B′ and B″ of planes P2 and P3, respectively. The interconnected second conductors 122 of illumination devices B, B′ and B″ are coupled to address conductor C2. This interconnection between the devices B, B′, B″ and address line C2 is illustrated by dashed line 1204.
The second conductors 122 of illumination device C of plane P1 is interconnected to the second conductors 122 of illumination devices C′ and C″ of planes P2 and P3, respectively. The interconnected second conductors 122 of illumination devices C, C′ and C″ are coupled to address line conductor C3, where the interconnection between the devices C, C′, C″ and address line C3 is illustrated by dashed line 1206.
Moreover, the second conductors 122 of illumination device D of plane P 1 is interconnected to the second conductors 122 of illumination devices D′ and D″ of planes P2 and P3, respectively. The interconnected second conductors 122 of illumination devices D, D′ and D″ are coupled to address line conductor C4. This interconnection between the devices D, D′, D″ and address line C4 is illustrated by dashed line 1208.
According to an aspect of the present invention, the described method of interconnecting the illumination devices reduces the number of required address lines needed to activate the illumination devices. In conventional 3D systems, each illumination device would require an independent series of address lines for facilitating the activation of each illumination device. For example an N×N×N array of devices would require N×N×N address conductors. However, an N×N×N array according to the present invention may only require (N×N)+N address conductors, which heavily reduces the burden, among other things, on wiring, address signaling and complexity, and potential faultfinding capabilities. This reduced conductor configuration may be derived from the scanned method used for accessing the illumination devices within each plane.
The method of addressing specific illumination devices based on, for example, an image data file comprises a scanned method, whereby the specific illumination devices within each plane are addressed, and thus activated, sequentially, plane-by-plane. This sequence may start from the top plane towards the bottom plane, and then repeat the same scanning pattern (i.e., top to bottom) for subsequent image frames in the data file. The scan rate may be controlled to generate a simultaneous image to the human eye. The scan may also be controlled in order to generate any other desired visual effect.
For example, specific illumination devices for generating a visual image are activated (i.e., addressed) by applying an electrical signal to both conductor AD1 and the appropriate address conductors (C 1-C4) coupled to the specific illumination devices (A, B, C, and/or D) within plane P1. Once the illumination devices in plane P1 are de-activated, an electrical signal is applied to both conductor AD2 and the appropriate address conductors (C1-C4) associated with the specific illumination devices (A′, B′, C′, and/or D′) within plane P2. Following the de-activation of the illumination devices in plane P2, electrical signals are applied to both conductors AD3 and the appropriate address conductors (C1-C4) associated with the specific illumination devices (A″, B″, C″, and/or D″) within plane P3. Because conductors C1-C4 are commonly connected to all planes, when these conductors C1-C4 are activated, the plane address lines AD1-AD3 of the active plane is active (e.g., positive voltage), while the address lines associated with the other planes are maintained in an inactive state (e.g., electrically grounded). Once all the planes are activated in the above-described manner, the process repeats, where the illumination devices in planes P1-P3 are activated sequentially based on the image data associated with each frame.
While the invention has been described and illustrated in connection with preferred embodiments, many variations and modifications as will be evident to those skilled in this art may be made without departing from the spirit and scope of the invention, and the invention is thus not to be limited to the precise details of methodology or construction set forth above as such variations and modifications are intended to be included within the scope of the invention. Except to the extent necessary or inherent in the processes themselves, no particular order to steps or stages of methods or processes described in this disclosure, including the Figures, is implied. In many cases the order of process steps may be varied without changing the purpose, effect or import of the methods described.
