## Background
CLAIM OF PRIORITY
This application claims prior of a U.S. Provisional Application No. 61/910,122, filed on Nov. 29, 2013, the contents of which are fully incorporated herein by reference.
FIELD OF THE INVENTION
The present invention relates to a micro-display device, in particular small tokens capable of displaying self-contained imagery data.
BACKGROUND OF THE INVENTION
Coined money has always served as an item of barter. Coins and tokens have been traditionally utilize to bestow some honor or accolade on their receiver or possessor. Coins still continue to fascinate collectors, and frequently are the main, or the only, actual physical item that still survives and testifies about bygone epochs.
Presently, coins or tokens have been primarily minted or forged to satisfy some single specific purpose. Changing this purpose requires minting a new or different coin. Furthermore, display space on the surface of a coin is extremely limited, causing the face to contain only the bare essentials. Fine details are often crude or left out altogether due to artificial curbs placed on production costs, and due to technological limitations of standard minting practices.
In some instances, tokens fulfill an educational or testimonial purpose by paying tribute to some object, place or event. In the latter capacity, a token has limited utility due to extremely limited space of the coin faces or top surfaces. The minters of such coins are faced with reducing the face image to some arbitrary symbol that represents the purpose of the coin. Frequently the symbol is meaningless to all except the select few that designed or approved the symbolic coin. The present invention aims to correct this existing shortcoming, by introducing descriptive pictures, graphics and short video clips that will be a lot more informative to wide audiences, and thus increase awareness or popularity of an object, place or event being depicted on such a coin.
Overwhelming majority of coins today that are used as money, albeit possessing little if any intrinsic value. Coins represent one of the earliest form of what used to be commodity money. Since it is generally easier to counterfeit coins than paper money, coins of higher value, like the Euro or the Dollar coins are frequently forged, prompting governments to take extensive measures to guard against counterfeiters. One of the main anti-counterfeiting measures has been the use of dual metal forging. The significant cost of this technique has been the main deterrent against forgeries. However, proliferation of sophisticated dyes has undermined the effectiveness of the dual forging technique.
The present invention can easily replace traditional coins as money, while at the same time tremendously shoring up the anti-counterfeiting measures. The minting authorities will now be able to implement efforts such as authentication ships, and the use of remote uploaded imagery that is synchronized with a central source. The ability the change images will serve to add tremendous flexibility to the appearance of a coin at any given moment, as well as counterfeit manufacturing much too expensive to justify the effort and the risks.
The present invention features a display screen that shows images of data that is stored within the display screen, or with the coin itself. The image displayed may indicate the source of the coin, the purpose of minting or monetary denomination. The display screen may be adapted to many purposes. Therefore, changing the stated value of a coin may be as easy as loading a new image or installing a new display screen.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
The preferred embodiments of the present invention will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals.
Reference will now be made in detail to embodiment of the present invention. Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto.
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, the figures illustrate several embodiments of the present invention. Seen in FIG. 1 a coin device 10, a module 20, a top area 120 also known as the coin face, and a protective casing 80. The radius 100, measured from the center 102 of the coin 10 to the edge 104, is preferably between five millimeters and ten centimeters. Of this radius 100, approximately between three millimeters and three centimeters is taken by the width of the border 106 formed by the protective casing 80 around the circumference of the coin 10. The border 106 may be uniform in width throughout the top area 120, or may be variable in embodiments where the display screen 30 is off center, is not a perfect circle, or is assembled as a square, a triangle or an alternative geometric shape. The top area may range between four square centimeters and twenty five centimeters, but other sizes are possible.
FIG. 2 is a high level cross sectional embodiment of the present invention. Shown in FIG. 2 are a module 20, a display screen 30, an integrated power source 50, on a system board 60, a storage module 264 (FIG. 9), a protective casing 80, a thickness 110, a top area 120, a bottom area 130, and a solar cell 170.
The module 20 is comprised of the display screen 30 and all protective and connective attributes of the display screen 30, as will be discussed shortly, including the integrated power source 50, and the system board 60. The system board 60 contains electronic circuitry required to enable the present invention and is preferably made from silicon, or other semi-conductive, non-conductive, high or low thermal materials. In some embodiments, the power source 50 may be present only during manufacturing phase, and used to imprint or “engrave” the image onto the display screen 30 for embodiment where the display screen 30 uses bistable or electronic ink technologies. Since in bistable displays electric current needs to be supplied only to make changes, display coins with a single stored image need only be “recorded” once and are then able to maintain the imprinted image without additional supply of electric power. Alternatively, such a coin 10 may provide means for exterior connection to a source of electric current, to enhance, change or recharge the image on the display screen 30.
FIG. 2 demonstrates a solar cell battery 170 as the power source 50. Furthermore, the solar cell is shown surrounding the display screen 30. The actual configuration of the solar cell 170 and the display screen 30 with respect to each other may vary. In some embodiments, the display screen 30 may be concentrated in one section of the top area 120, while the solar cell battery 270 in another section. The power source 50 may also be disposed within the side 210.
The preferred total thickness 110 of the present invention is between three millimeters and one centimeter, which includes the thickness of the module 20 combined with the bottom side 220. The actual thickness of the module 20 and the bottom side 220 may vary depending on an embodiment. The thickness 110 may be uniform throughout the cross-section of the coin 10, or may vary between areas closest to the sides 210 and the center 102. For example in convex or concave embodiments of the coin 10 the thickness 110 will vary depending on how close or far apart from the center 102 is the point where the thickness measurement is taken (FIGS. 6A and 6B).
The protective casing 80 may be manufactured out of a single section of materials or may be comprised of several components, which may be of the same or different material as the other sections of the protective casing 80. The materials for the protective casing 80 should preferably possess surface and structural hardness with exceptional durability.
