No. 6,674,562), which is a continuation-in-part of:
(1) U.S. patent application Ser. No. 08/769,947, filed Dec. 19, 1996 (now abandoned), (2) U.S. patent application Ser. No. 08/554,630, filed Nov. 6, 1995 (now abandoned), and (3) U.S. patent application Ser. No. 08/238,750, filed May 5, 1994 (now U.S. Pat. No. 5,835,255). The disclosures of all the above-referenced prior applications, publications, and patents are considered part of the disclosure of this application, and are incorporated by reference herein.
FIG. 8 is a timing diagram for driving a binary IMod.
FIGS. 27A, 27B, 27C, 27D, 27E, 27F and 27G are views of an IMod display used in applications for information and decorative display, a remote control, and components diagrams. FIGS. 27A,27B, and 27D show several examples, FIG. 27C shows a components diagram, FIG. 27E shows a remote control, and FIG. 27F shows another components diagram.
FIGS. 29A, 29B, and 29C are views of an IMod array used as a billboard display. FIG. 29A shows a full billboard, FIG. 29B shows a display segment, and FIG. 29C shows a segment pixel.
Each IMod 114, 116 is rectangular and connected at its four corners to four posts 118 via support arms such as 120 and 122. In some cases (see discussion below), the IMod array will be operated at a stated constant bias voltage. In those cases, the secondary mirror 102 will always maintain a quiescent position which is closer to corresponding primary mirror 128 than without any bias voltage applied. The fabrication of IMods with differently sized support arms allows for the mechanical restoration force of each IMod to be determined by its geometry. Thus, with the same bias voltage applied to multiple IMods, each IMod may maintain a different biased position (distance from the primary mirror) via control of the dimensions of the support arm and its resulting spring constant. The thicker the support arm is, the greater its spring constant. Thus different colors (e.g., red, green, and blue) can be displayed by different IMods without requiring deposition of different thickness spacers. Instead, a single spacer, deposited and subsequently removed during fabrication, may be used while color is determined by modifying the support arm dimensions during the single photolithographic step used to define the arms. For example, in FIG. 2, IMods 114, 116 are both shown in quiescent states with the same bias voltage applied. However, the gap spacing 126 for IMod 114 is larger than gap spacing 128 for IMod 116 by virtue of the larger dimensions of its respective support arms.
As shown in FIGS. 5A through 5C, to minimize color shift as the angle of incidence changes (a characteristic of interferometric structures) IMod structures 502, 506 are fabricated to have a very high aspect ratio, i.e., they are much taller than they are wide. Consequently, they only exhibit interferometric behavior within a narrow cone 501 of incidence angles. Incident light 500 which is within cone 501, as in FIG. 5A, interacts with the multiple layers (shown by striped sections in the figure) the composition and configuration of which are dictated by the design of the IMod. In general, as indicated in the previous patent applications, these can consist of combinations of thin films of metals, metallic oxides, or other compounds. The important fact being that the geometry of the stack dictates that interference occurs only within a narrow cone of incidence angles. On the other hand, as seen in FIG. 5B, incident light 504 (outside of the cone) is relatively unaffected by the IMod because it interacts with only a very few layers. Such an IMod would appear, say blue, to a viewer who looks at it from a narrow range of angles.
In a digital driving scheme, as shown in FIGS. 8, 9, and 10, FIG. 8 is a timing diagram showing one set of voltages required to actuate a matrix addressed array of IMods. Column select pulses 800 and 802 are representative of what would be applied to a particular column. Further detail is revealed in pulse 800 which is shown to switch from voltage level Cbias to voltage Cselect. Row select pulses 804 and 806 are also shown, with 804 revealing that the required voltage levels are Rselect, Rbias, and Roff (O volts). When a column select pulse is present, and a row select pulse is applied, the pixel which resides at the intersection of the two is actuated as shown in the case of pixel 808 which resides on the row driven by select pulse 804, and subsequently in pixel 810, which resides on the row driven by pulse 806. When select pulse 804 is driven to the Roff level, pixel 808 is turned off. Pixel 812 illustrates the behavior of a pixel in an arbitrary state when a Roff value is placed on the row line, i.e., if it is on it turns off, or if it is off it remains off.
Referring to FIGS. 28A and 28B, even larger IMod arrays are shown incorporated into the exterior of an automobile. In this case body panels 2800, 2802 as well as windows 2804, could use reflective and transmissive IMod designs respectively. Dynamic control of the exterior appearance of a car would be a very appealing option for the owner, providing the ability for the owner to customize the appearance himself, or to “download” exteriors in a digital fashion. Such a control 2806 could take the form of a small panel integrated into the dashboard which displayed various exteriors under button control. The same techniques could be applied to other highly style oriented goods in the class and functional category, including motorcycles, sailboats, airplanes and more. FIG. 28B shows a components diagram illustrating one way in which this product could be implemented using off-the-shelf components. In general, they comprise a central controller 2808 (including processor 2810, memory 2812, and low level I/O 2814), high level I/O components (user interface 2816, and logic 2818), display 2828 (logic 2826, drivers 2824, IMod array 2822) and power supply 2820. The central controller handles general purpose operational functions, while high level I/O components dictate how information gets in and out of the product.
Referring to FIGS. 29A through 29C, billboard-sized arrays 2900 of IMod display segments could be assembled and replace current static displays used for advertising and public service announcements. Display 2900 would include reflective devices to be illuminated by ambient light or a supplemental light source 2902. A large display could be assembled from individual segments 2904 (FIG. 29B) which would support segment pixels 2906. Each segment pixel would include three sets of sub-pixel arrays 2910, 2912, and 2914, which would reside on pixel substrate 2908 (FIG. 29C). The resulting large displays could range from placards on the sides of buses and inside of subways, to billboards, to entire architectural structures such as homes or skyscrapers. In FIG. 30A, skyscraper 3000 is an example of a large building which exploits the aesthetic and cheap manufacture of the IMod array. All of the glass used in the manufacture of such structures is coated with thin films up to 4 or more layers thick to provide energy efficient coatings. Similar coating techniques could be applied to the manufacture of the IMod arrays. FIG. 30B shows a components diagram illustrating one way in which both of these products could be implemented using off-the-shelf components. In this case, they comprise a central controller 3002 (including processor 3004, memory 3006, and low level I/O 3006), high level I/O components (PC based user interface 3008), display 3020 (logic 3018, drivers 3016, IMod array 3014), lighting control 3012, and power supply 3010. The central controller handles general purpose operational functions, high level I/O components dictate how information gets in and out of the product, and the controller components manipulate supplementary lighting and peripheral components.
