REFLECTIVE ELECTRO-OPTIC FIBER-BASED DISPLAYS

Abstract: A reflective display is formed using two orthogonal fiber arrays and an electro-optic material. The bottom fibers contain plasma channels, used to address the electro-optic material. Wire electrodes built into the fibers address both the plasma and the electro-optic material. The fibers are composed of glass, plastic or a combination of glass and plastic. Color is imparted into the display using colored fibers, adding a color coating to the surface of the fibers, or adding the color to the electro-optic material. The electro-optic material consists of a liquid crystal material, electrophoretic material, bichromal sphere material, electrochromic material, or any electro-optic material that can serve to create a reflective display. Another possible reflective display is formed using an array of hollow tubes filled with an electrophoretic material sandwiched between two plates.

Description: REFLECTIVE ELECTRO-OPTIC FIBER-BASED DISPLAYS REFERENCE TO RELATED APPLICATIONS This is a continuation-in-part of co-pending U.S. Patent Application serial number 09/621,193, filed July 21, 2000, entitled REFLECTIVE ELECTRO-OPTIC FIBER- BASED DISPLAYS WITH BARRIERS which is a continuation-in-part of co-pending U.S. Patent Application serial number 09/517,759, filed March 2, 2000, entitled REFLECTIVE ELECTRO-OPTIC FIBER-BASED DISPLAYS, which is a continuation- in-part of co-pending U.S. Patent Application serial number 09/299,372, filed April 26, 1999, entitled FIBER-BASED PLASMA ADDRESSED LIQUID CRYSTAL DISPLAY. The aforementioned applications are hereby incorporated herein by reference. FIELD OF THE INVENTION The invention pertains to the field of reflective displays and methods of manufacture. More particularly, the invention pertains to addressing electrophoretic, electrochromic, .and bi-chromal sphere displays and fabricating such displays using fibers. The invention also pertains to electrophoretic displays containing barrier walls and barrier electrodes, and fabricating such displays using fibers and/or hollow tubes. BACKGROUND OF THE INVENTION There are several different methods of producing a reflective display. The most well known and widely used method is to use liquid crystal molecules as the electro-optic material. In the liquid crystal family, a vast range of molecules could potentially be used to create reflective displays. Some of these liquid crystal molecules include, twisted nematic, cholesteric-nematic, dichroic dye (or guest-host), dynamic scattering mode, and polymer dispersed to name a few. Most of these liquid crystal molecules require other films, such as, alignment layers, polarizers, and reflective films. Another type of reflective display composing an electro-optic material is an electrophoretic display. Early work such as that described in U.S. Patent No. 3,767,392, "Electrophoretic Light Image Reproduction Process", used a suspension of small charged particles in a liquid solution. The suspension is sandwiched between to glass plates with electrodes on the glass plates. If the particle have the same density as the liquid solution then they will not be effected by gravity, therefore the only way move the particles is using an electric field. By applying a potential to the electrodes, the charged particles are forced to move in the suspension ' to one of the contacts. The opposite charge moves the p.articles to the other contact. Once the particles are moved to one of the contact they reside at that point until they are moved by another electric field, therefore the particles are bistable. The electrophoretic suspension is designed such that the particles are a different color than the liquid solution. Therefore, moving the particles from one surface to the other will change the color of the display. One potential problem of this display is the agglomeration of the small charged particles when the display is erased, i.e., as the pixel is erased the particles are removed from the contact in groups rather than individually. The invention of microencapsulating the electrophoretic suspension in small spheres solves this problem, U.S. Patent No. 5,961,804, "Microencapsulated Electrophoretic Display." Figure 1 shows the typical operation of a microencapsulated electrophoretic display, hi this display the particles are positively charge and are attracted to the negative terminal of the display. The charged particles are white and the liquid solution they are suspended in is dark, therefore contrast in the display is optionally achieved by selectively moving some of the particles form one contact to the other. In this type of display, the electro-optic material is the electrophoretic material and any casing used to contain the electrophoretic material. A similar type of electro-optic display, a twisting ball display or Gyricon display, was invented by N. Sheridon at Xerox, U.S. Patent No. 4,126,854, "Twisting Ball Display." It was initially called a twisting ball display because it is composed of small spheres, one side coated black, the other white, sandwiched between to electroded glass plates, as shown in Figure 2. Upon applying an electric field the spheres with a positive charged white half and relative negative charged black half are optionally addressed (rotated). Once the particles are rotated they stay in that position until an opposite field is applied. This bistable operation requires no electrical power to maintain an image. A follow on patent, U.S. No. 5,739,801, disclosed a multithreshold addressable twisting ball display. In this type of display, the electro-optic material is the bichromal spheres and any medium they may reside in to lower their friction in order to rotate. Another major electro-optic display is that produced using an electrochromic material. An electrochromic display, similar to that in U.S. Patent No. 3,521,941, "Electro-optical Device Having Variable Optical Density", is a battery which has one of the electrodes serving a display function. An electrochemical display stores electrical energy by changing it into chemical energy via an electrochemical reaction at both electrodes. In this reaction, electrochemically active material is plated-out on one of the contacts changing it from transparent to absorbing. Figure 3 shows the typical reaction of an electrochromic display, where an electrochemical reaction from the applied voltage causes material to plate out on the negative terminal of the display. In this type of display, the electro-optic material is the electrochromic material, which is sandwiched between the electroded plates. Most of the electro-optic displays have problems with addressing the display. Since most of the electro-optic materials do not have a voltage threshold, displays fabricated with the materials have to be individually addressed. Some of the liquid crystal materials use an active transistor back plane to address the displays, but these type of displays are presently limited in size due to the complicated manufacturing process. Transmissive displays using liquid crystal materials and a plasma addressed back plane have been demonstrated, US Patent 4,896,149, as shown in Figure 4, however, a reflective display using such a technique has not be disclosed. In addition, displays fabricated using the plasma addressed back plane shown in Figure 4 are also limited in size due to availability of the thin microsheet 33. One potential solution for producing large size displays is to use fibers to create the plasma cells as shown in Figure 5. Using fibers to create a plasma cell was first disclosed in U.S. Patent No. 3,964,050, and using fibers to create the plasma cell in a transmissive plasma addressed liquid crystal display was disclosed in U.S. Patent No. 5,984,747. Another method of producing a reflective display uses an electrophoretic switching material. Early work such as that described in U.S. Patent No. 3,767,392, "Electrophoretic Light Image Reproduction Process", used a suspension of small charged particles in a liquid solution (electrophoretic suspension) for displaying a light image. The suspension is sandwiched between two glass plates with electrodes on the glass plates. If the particles have the same density as the liquid solution then they will not be effected by gravity, therefore the only way to move the particles is by using an electric field. By applying a potential to the electrodes, the charged particles are forced to move in the suspension to one of the contacts. The opposite charge moves the particles to the other contact. Once the particles are moved to one of the contacts, they reside at that point until they are moved by another electric field, therefore the particles are bistable. The electrophoretic suspension is designed such that the particles are a different color than the liquid solution. Therefore, moving the particles from one surface to the other will change the color of the display. As mentioned above it is very difficult to address most electrophoretic displays because electrophoretic materials do not have a voltage threshold. Therefore, displays fabricated with the electrophoretic materials have to be individually addressed at each pixel by using active devices such as a transistor array or a plasma. Active devices are complicated and expensive to fabricate and are usually limited in size. Therefore, an addressing scheme where the display can be passively addressed is desired. One such addressing scheme was introduced by Philips in U.S. Patent 4,203,106 where they added a third control electrode to create a voltage threshold to manage the migration of particles. This third electrode is patterned with holes and is placed over and orthogonal to the attraction electrode. Controlling the voltage on the control electrode causes the particles to migrate into the holes in the control electrode, in turn, changing the color of the display. Another passively addressed display was invented at Copytele, U.S. Patent 5,345,251. This display is constructed using interleaved electrodes and an orthogonal electrode. The movement of the particles is in the plane between the interleaved electrode and is controlled by the orthogonal electrode. The addressing electrode controls the movement of the particles in all of these passively addressed displays. Since the particles do not have a voltage threshold, it makes it very difficult to matrix address the display. In order to achieve passive matrix addressing, a barrier must be added to the cell between the two driving electrodes. A display that uses a barrier between drive electrodes was disclosed by E. Kishi, et al., "Development of In-Plane EPD", SID 00 Digest, pp. 24-27. Two types of barriers were disclosed: a physical barrier 48, shown in Figure 6, and an electrical barrier 44, shown in Figure 7. Both displays are constructed by building up the structure on a top 30T and a bottom 3 OB substrate. A separator 45 is used to create the cell that houses the electrophoretic material 37. The drive electrodes 43 and 42 are electrically isolated from the cell and each other using dielectric layers 46 and 47. The operation of these displays is achieved by placing voltages on both driving electrodes 43 .and 42 .and controlling the flow of particles over the barriers using the control electrode 41. Assuming the particles 37 are positively charged, then the display is in a holding state when a large positive voltage is applied to the control electrode 41, a small positive voltage is applied to the 1 st driving electrode 43, and a negative voltage is applied to the 2 nd driving electrode 42. In the case where the barrier is created by an electric field (Figure 6), a positive voltage is applied to the barrier electrode 44. To move the particles 37 from the 1 st driving electrode 43 to the 2 nd driving electrode 42, the positive voltage on the control electrode 41 is reduced. In this case, the particles 37, which are repelled from the 1st driving electrode 43, are allowed to flow over the barrier to the 2 nd driving electrode 42. This passive method of addressing by adding barriers helps in addressing the pixel, but has problems addressing more than one row in a display. In addition, the display will have a high manufacturing cost because of the multiple steps needed to create the structure and pattern the electrodes in the display. The display will also be limited in size since the structure is built-up on a substrate. The following invention solves the manufacturing and addressing issues and is cost effective in a large panel display. SUMMARY OF THE INVENTION The invention includes the use of fibers with wire electrodes to construct reflective fiber-based displays, where reflectivity is formed by modulating an electro-optic material within the display. A plasma channel is optionally built into the display to address the electro-optic material. The plasma channel is optionally totally contained within the fibers and addressed using wire electrodes. The wire electrodes are contained within the fiber or on the surface of the fiber. The fibers are optionally colored to impart color to the display, or are optionally black to serve as an absorbing layer to enhance the contrast of the display, or white to enhance the reflectivity of the display. The electro-optic material consists of a liquid crystal material, electrophoretic material, bichromal sphere material, electrochromic material, or any electro-optic material that can serve to create a reflective display. In addition, colored pigment is optionally added to the electro-optic material to impart color to the display. The fibers are optionally composed of glass, glass ceramic, plastic/polymer, metal, or a combination of the above. The invention also includes the use of hollow tubes filled with an electrophoretic material sandwiched between two plates to form a reflective display. The hollow tubes have either barrier walls or an electrostatic barrier, which restricts the flow of electrophoretic particles within the hollow tubes. The flow of electrophoretic particles over these barriers is controlled using electric fields, which makes it possible to matrix address the electrophoretic displays. Wire electrodes built into the hollow tubes and electrodes on the two plates are used to create the electric field and address the display. The electrodes on the plates can be replaced with wire electrodes or wire electrodes contained within a fiber. The plates are preferably composed of glass, glass-ceramic, polymer/plastic or metal, while the hollow tubes are preferably composed of glass, polymer/plastic or a combination of glass and polymer/plastic. In addition, color is optionally imparted into the display using colored tubes, adding a color coating to the surface of the tubes, or adding the color to the electrophoretic material. Reflectivity within the display is accomplished by using a reflective material to fabricate the tubes, coating the tubes with a reflective material or coating one of the two plates with a reflective material. The display can also function in a transmissive mode by applying an illuminating back to the display.

DESCRIPTION OF THE PREFERRED EMBODIMENT The invention includes the use of fibers with wire electrodes to construct reflective fiber-based displays, where reflectivity is formed by modulating an electro-optic material within the display. The wire electrodes are contained within the fiber or on the surface of the fiber. The fibers are optionally colored to impart color to the display, or are optionally black to serve as an absorbing layer to enhance the contrast of the display, or white to enhance the reflectivity of the display. The electro-optic material consists of a liquid crystal material, electrophoretic material, bichromal sphere material, electrochromic material, or any electro-optic material that can serve to create a reflective display. Most of these electro-optic materials are bistable in their operation. In addition, colored pigment is optionally added to the electro-optic material to impart color to the display. The fibers are optionally composed of glass, glass ceramic, plastic/polymer, metal, or a combination of the above. The term fiber is used to explain any long linear structure either in a solid or tubular foim usually supporting a complex, non-circular cross-section. Figure 5 shows a schematic of a plasma addressed liquid crystal (PALC) display using both top 17 and bottom 27 fibers to create the structure in the display, as disclosed in US Patent Application No. 09/299,372. Modifying the top fiber 17 in this fiber-based PALC display, such as shown in Figure 8, would create a reflective display. To create a reflective display, the traditional liquid crystal, alignment layers and polarizers are replaced with an electro-optic material 37. Legs or ribs 90 are optionally formed on the ends of the top fiber 17 to create a channel to support the electro-optic material 37. Upon operation, a plasma is ignited in the plasma channel 35 using the plasma address electrodes 36. The plasma creates many electrons and ions in the plasma channel 35. During or shortly after the plasma glow period, a voltage is applied to the address electrodes 31 in the top fiber 17. This voltage, if positive relative to the plasma address electrodes 36, will plate a negative charge out on the upper inside surface of the plasma channels 35, directly below the electro-optic material 37. After the plasma is extinguished, the free carriers diminish from the plasma gas, leaving the negative charge or electrons on the upper surface of the channel 35. Upon removing the applied voltage from the address electrodes 31, an electric field is set up between the deposited charge and the address electrodes 31. This electric field will slowly modulate the electro-optic material. Note that the plasma addressing time is much faster than the response time of the electro-optic material. Because the charge on the inner surface of the plasma cell 35 is not stable, the plasma may have to be addressed more than once per image frame in order to fully address the electro-optic material. Gray scale images are optionally created in the display by controlling the address voltage or by dividing the addressing time into sections or bits, similar to the addressing scheme of a plasma display. The time the charge is plated-out in the plasma channel 35 is optionally broken down into 8-bit increasing time domains, or 256 levels of gray scale. Another method of creating a gray scale image is to divide the address voltage between the address electrodes 31. Applying the full on address voltage to one of the address electrodes will cause the electro-optic material to switch below that wire electrode and not the other. Thus, two bits of gray scale are optionally created if there are two electrodes and the voltage is full on or full off. If the voltage is divided between the two electrodes and its magnitude is also controlled, then the total number of gray scale levels equals the voltage bits of gray scale times the number of electrodes, hi addition, using separate wires to address a bichromal sphere twisting ball display would allow the ball to be rotated to specific angles. Rotating the ball to a specific angle not only controls the gray scale, but also controls the direction of the reflected light. Controlling the direction of reflected light is extremely useful to maximize the usage of a point light source, such as, for example, the sun. Figure 9 is a schematic cross-section of a top fiber 17 similar to that shown in Figure 8, except the sides of the fiber 52 are black or absorbing to create a black matrix function. The absorbing sides 52 are optionally included in the top fiber 17, or are optionally coated on the surface of the fiber 17. The fibers are optionally composed of either an inorganic material, such as, for example, glass, or an organic material, such as, for example, an organic polymer. The black matrix 52 helps to define the pixels and create a sharper image. Figures 10A and 10B show a method of controlling the electric field around the address electrodes 31. Contouring the surface 39T of the top fiber 17 allows for tight control of the shape of the electric field lines through the electro-optic material 37. The voltage drop (electric field) from the address electrodes 31 to the electrons in the plasma channel is divided between the glass or plastic in the top fiber 17, between the address electrodes 31 and the surface of the fiber 39T, the electro-optic material 37, and the thin glass membrane at the top of the plasma channel 35. In order to obtain close to vertical electric field lines in the electro-optic material 37, the surface 39T of the top fiber is modified, depending on the dielectric constant of the top fiber 17 material and the electro- optic material 37. Figure 10A depicts a concave surface contour 39T, which is needed to produce vertical electric field lines if the electro-optic material has the higher dielectric constant. Figure 10B depicts a convex surface contour 39T, which is needed to produce vertical electric field lines if the top fiber 17 material has the higher dielectric constant. Note that although the figures depict two address electrodes 31, any number of address electrodes can be used per pixel. Figure 11 shows a method of exposing the electrodes to the surface, using a lost glass process similar to that disclosed in patent application 09/299,394, "Lost Glass Process Used in Making Fiber-Based Displays", the disclosure of which is hereby incorporated herein by reference. A dissolvable glass 95 is optionally co-extruded with the base glass 27, to form a preform for fiber draw. The wire electrodes 31 .are optionally drawn into the fiber, shown in Figure 11 A, and the dissolvable glass 95 is optionally subsequently removed with a liquid solution, as shown in Figure 1 IB. Typical liquid solutions to dissolve the glass include, for example, vinegar and lemon juice. A dissolvable glass 95 is optionally used to hold the wire electrode in a particular location during the draw process. When the dissolvable glass 95 is removed, the wires become exposed to the environment outside the fiber. If the fiber is formed using a polymer, then two different polymers are needed, where one polymer is optionally removed without effecting the other. This removal process is optionally by wet etching, dry etching or thermal treatment. Creating a conductive path between the electrodes and the electro-optic material is necessary for the electrochromic displays and most electrophoretic displays. Figure 12 shows a method of creating a conductive surface by applying a conductive material 3 IT to the surface of the fiber and in contact to the conductive wire electrodes 31. This conductive material 3 IT must be tr.ansparent. The conductive layer is optionally added to the preform during the draw or extrusion process, or added to the fiber after it has been drawn. Figure 13 illustrates a cross-section of a hollow tube 27 with a conductive region 38 extending through the wall of the hollow tube 27. This conductive region 38 electrically connects the inside of the tube to the outside of the tube. Therefore, if the hollow tube 27 was backfilled with a plasma gas and a plasma was ignited between the plasma electrodes 36 then charge form the plasma could flow through the wall 38 to the outside surface. In the case of the plasma-addressed electro-optic display, shown in Figure 14, current would flow from the plasma 35 through the wall 38 of the hollow tube and through the electro-optic material 37 to the top address electrode 3 IT. Assuming the electro-optic material 37 is an electrophoretic material composed of TiO particles, then the charge flowing through the system will charge the TiO 2 particles and allow them to move within the electrophoretic cell. Conductive regions could also be formed in the structure 39P used to house the plasma electrodes 36 during the draw process. Creating a conductive region 39P around the plasma electrodes 36 will electrically connect the plasma electrodes 36 to the plasma region. This will change the plasma firing from AC to DC and help drain the charge from the plasma cell after plasma ignition. A conductive region can be formed using several different methods. One method is to place small conductive particles into the preform before fiber draw. The small conductive particles can be mixed into the base glass and added to the preform. Therefore, during the fiber draw process the small conductive particles will flow with the glass and form a fiber/hollow tube with a conductive wall. The glass composition mixed into the small particles may need to be modified to be expansion matched to the base glass that forms the preform/fiber. The small particles can be composed of metal or an alloy, such as W, Ti, Ta, Mo, Nb, Cr, Fe, Co, Ni, Cu, Pt, Au, Zr, etc., and can contain a multitude of shapes, such as, spherical, elliptical, or even whiskers. The particles would also be composed of a semiconductor material such as SiC, TiO 2 , CuS, etc. and can also take on any shape, such as, spherical, elliptical, whiskers, etc. These small particles can be mixed and sintered into a glass powder to be added to a preform, which is drawn to the final fiber size. Another method of creating a conductive region 38 is to simply use conductive glass. Conductive glass is somewhat of an oxymoron, however, there are some high Cu and Pb containing glasses that have reasonable conductivity. Precipitating small conductive spheres out in the glass produces a conductive phase separated glass where conductivity is created by electron hopping from one conductive particle to the next. A glass can also be ceramed to produce small crystals that are conductive. The glass regions that are to be ceramed can be composed of a glass-ceramic. Another method is to use a ceramable glass for the entire preform and then only cera the areas of interest. A laser can be used to induce a ceramable region, where crystals grow in the laser written areas during the post heat treating process step. Therefore, selective areas along the fiber can be ceramed to create conductive regions. Figure 15 shows two different methods of adding color to the displays. First, the fibers 17R, 17G, and 17B are optionally colored. The fibers 17 are optionally colored by adding a color agent to the base fiber material before foiming the fibers 17. The fibers 17 .are optionally colored by applying a thin colored film to the surface of the fiber. Adding a color film to the surface is similar to what is done in the liquid crystal display industry to create a color filter. Another method of adding color to the display is to add color to the electro-optic material 37R, 37G, and 37B. In the bichromal sphere display, one half of the sphere can simply be made from a colored material. In the electrophoretic material the color is optionally added to either the small charged particles or the liquid suspension solution. Figure 16 shows a reflective display with an array of bottom fibers 17B that form one half of the display, and a top plate 30T forming the other half. The bottom fibers 17B have channels that support an electro-optic material 37, and wire electrodes 31 to address the electro-optic material. The top plate 30T has transparent electrodes 3 IT to address the electro-optic material 37. To complete the display, a substrate may be required below the bottom fibers 17B, such that the fiber array 17B is sandwiched between the two plates. The plates are optionally made of glass or plastic. The top plate is optionally replaced with an array of fibers 17T to make a total-fiber display, as shown in Figure 17. This total-fiber display may have to be sandwiched between two plates to add rigidity to the display. Additional structure is optionally added to the top fiber 17T to form a channel to support an electro-optic material 37, as shown in Figure 18. Identical fibers are optionally used for the top 17T and 10 bottom 17B fiber arrays. Note that the fibers are not rigid and are optionally bent around a curved surface, therefore fabricating a curved display. One problem with using an array of fibers to create the structure of the reflective display is presented by the additional surfaces created between the top plate 30T and the fiber array 17. These additional surfaces create a reflection, which lowers the contrast ratio of the display. To reduce or eliminate these reflections, a flowable polymer material is optionally included into the structure between the top plate 30T and the fiber array 17. A polymer material, such as, for example, ethylvinyl acetate, EVA, is optionally used to remove these reflections. Another method of removing the reflections at the fiber/substrate interface is to use an index matching oil. Using an oil medium with the same or similar index of reflection to the fibers and substrate(s) will drastically reduce or eliminate the amount of light reflected at the interfaces. This method of adding oil to reduce the reflection would be very advantageous if a bichromal sphere twisting ball material is used as the electro-optic material. The bichromal sphere twisting ball material is traditionally made by mixing small bichromal ball (black on one side and white on the other) in a polymer to form a film. The film is then treated to create an open cell structure around the bichromal balls. Silicone oil is then added to the film to float the bichromal balls and add lubrication around them so they can rotate. To keep the bichromal balls rotating over the life of the display it would be advantageous to have the film housing the bichromal spheres continually soaking in oil. Structure could also be added to the fibers to assist in getting the oil to flow into the interface between the fibers and/or fibers and substrate(s). The fibers 17 could be bowed inward with respect to its cross-section to create a gap 74 between the fiber 17 and the top substrate, as shown in Figure 19. Legs 72 could be added to the surface of the fibers 17, as shown in Figure 20, to create small cell gaps 74 for fluid flow. An oil reservoir could also be added to the display to house a volume of oil to control the amount of oil need during the temperature cycles of the display. Figure 21 shows a reflective electro-optic display similar to that shown in Figure 5 except the spacers 90 that create a channel for the electro-optic material 37 are contained in the bottom fibers 27. This type of display is operated very similarly to the one in Figure 5. A plasma is ignited in the plasma cell region 35 using the plasma address electrodes 36, and a voltage is applied to the transparent electrodes 3 IT in the top plate 30T. This applied voltage is used to store the charge on the upper inside surface of the plasma channel 35. The stored charge creates an electric field between the charge and the transparent electrodes 3 IT. The electric field modulates the electro-optic material 37. Replacing the top plate 30T with fibers containing wire electrodes 31, as shown in Figure 22, creates a total-fiber plasma display. Creating a total-fiber display not only allows for the fabrication of very large displays, but also allows for fabrication of curved, 3-D, and multiple view displays, if a lens function is built into the top fiber 17, as discussed in patent application entitled "FIBER-BASED DISPLAYS CONTAINING LENSES AND METHOD OF MAKING SAME," filed on March 2, 2000, the complete disclosure of which is hereby incorporated herein by reference. A lens built into the top fiber 17 alters the refection of the light going through the fiber. The lens is used to create a three- dimensional (3-D) image by changing the focus of light passing through the fiber. The lens is also be used to direct the light that passes through the fiber. Directing the light yields a brighter image in a given location, and can optionally create multiple images. Note that 3-D and multiple- view reflective displays may require more than one fiber with a given lens function to create such images. One problem in the art is addressing the plasma in the bottom fibers over a long distance and creating a vertical electric field through the elecfro-optic material. The display shown in Figure 23 solves both of these problems. The bottom fibers 27 .are used to address the plasma, as explained above. The top fibers 17 are designed to both support the elecfro-optic material 37 and address the plasma, using the wire address electrodes 31 A. The top glass plate 30T has a transparent conductive layer 3 IT that is used as the ground plane for the plated-out charge in the plasma cells 35, hence creating an electric field through the electro-optic material 37. The extra set of electrodes 31 A and ground plane electrode 3 IT make the display extremely easy to fully write or fully erase the electro-optic material 37. The ground plane electrode 3 IT is optionally included in the top fiber to create a total-fiber display, as shown in Figure 24. In this case, the ground plane electrodes 31S are optionally individually addressed per each top fiber 17. Figure 25 illustrate a method of adding a charging electrode 77 to the hollow plasma tubes 27 to assist in addressing the display. The charging electrode 77 should be discontinuous along the length of the plasma tube 27. The charging electrode 77 could be composed of randomly distributed conductive particles. If a high density is required the conductive particles could be composed of a metal with an oxidized surface to create isolation between the metal particles. The conductive particles could also be mixed with a glass to isolate them. The charging elecfrode 77 could be added to the inside surface of the hollow tube 27, as shown in Figure 25A, or inside the wall of the hollow tube 27, as shown in Figure 25B, or on the outside surface of the hollow tube 27, as shown in Figure 25C. The charging electrode 77 would serve a similar purpose as the traditional inside surface of the plasma tube 27 in storing charge to address the electro-optic material. But, the charging electrode 77 could be designed to not loose its charge during the firing of the plasma within the plasma tube 27. Therefore, allowing for a sequential addressing scheme of the address electrodes for each plasma tube. This sequential addressing scheme would allow for a reduction in electronics cost by using an electronics driver similar to that shown in Figure 37. Figure 26 illustrates a reflective display where the electro-optic material 37 is totally contained within the fiber 27. The electro-optic material 37 is addressed using a plasma similar to that explained above, but the plasma channel is formed by making a vacuum-tight seal between the fibers 27 .and the bottom plate 3 OB, or between the two plates 30T and 3 OB. The plasma electrodes 36 are used to ignite the plasma in the plasma channel 35, and the transparent electrodes 3 IT on the top plate 30T, are used to pull the electrons out of the plasma and plate them out on the upper top surface of the plasma channel 35. h this display, like the above display, the plasma is addressed one line at a time along the plasma channels. Figure 27 illustrates a different method of addressing the plasma part of the display. The addressing technique is similar to that of a surface discharge plasma display. In this example, sets of parallel sustain electrodes 11 extend the length of the "top" fibers 17. An AC voltage is applied to the sustain electrodes 11, which is large enough to sustain a plasma, but not large enough to ignite the plasma. A short voltage pulse is then added to the plasma address electrodes 21 at the pixel location where addressing is desired. This short voltage pulse adds to the electric field of the sustain electrodes and locally ignites the plasma. After all the plasma cells are written, a voltage is applied to the top tr.aήsparent conductive elecfrode 3 IT to pull the electrons out to the plasma and plate them out on the upper inside surface of the written plasma channels 35. After the electrons are plated out, the voltage on the transparent electrode 3 IT is removed, and an electric field is produced across the electro-optic material 37 as a result of the stored charge. A total-fiber display is optionally constructed by including the transparent elecfrode 3 IT into the "bottom" fiber 27, as shown in Figure 28. In this case, wire electrode 31 serves as the address elecfrode for the electro-optic material. One potential problem with the reflective display discussed in Figures 26-28 is that the entire display will have to be glass frit sealed around the perimeter of the display to contain the plasma gas. This glass frit-sealing step usually requires a process temperature of about 400 °C, which could cause harm to the electro-optic material, especially if it is composed of an organic material. One method of addressing the plasma at each pixel in the display and containing the plasma in individual tubes is shown in Figure 29. In this figure, sustain electrodes lla and 1 lb along with the electro-optic material 37 are contained in one fiber 17. This fiber array 17 is placed over and orthogonal to a second fiber array 27 that contains the address electrode 21 and the plasma cell region 35. There are two traditional methods used to address a capacitively coupled plasma. The first is to essentially tie electrodes lla and 1 lb together and use them as one electrode and electrode 21 as the other. Applying a voltage between the electrodes (l la, 1 lb) and 21 will ignite the plasma in the plasma cell region 35 at the crossing of the two electrodes. The plasma is sustained by applying an AC voltage between the electrodes. During the AC voltage electrons are swept back and forth between the address electrodes. These electrons plate out on the dielectric material around the electrode and are used to assist the igniting of the plasma in the next cycle of the AC voltage. Therefore, these electrons can be used to address the electro-optic material by choosing the proper phase of the AC voltage to stop the plasma addressing. If the pixel is to be ON, i.e. the electro-optic material is to be modulated, then the last plasma addressing of the pixel should be with a positive voltage on electrodes l la and 1 lb. Likewise, if the pixel is to OFF then the positive voltage should be applied to electrode 21 during the last plasma addressing cycle. Choosing the phase to stop the plasma addressing will determine whether or not there are electrons plated out at the top of the plasma channel 35 to address the electro-optic material 37. These plated-out electrons serve to create a field between the elecfro-optic material by communicating with the electrode 3 IT above the electro-optic material 37. In addition, the electrode 3 IT on the top plate 30T can be replaced with wire electrodes 3 IS at the top of the fiber 17, as shown in Figure 24. The second traditional method of addressing the plasma at each individual pixel is to apply an AC voltage between electrodes lla and 1 lb that is high enough to sustain a plasma, but not high enough to ignite a plasma in the plasma cell region 35. Then by applying an address voltage to elecfrode 21 the plasma can be locally ignited. Each phase of the AC will result in electrons, which are plated out on the dielectric layer around one of the sustain electrode, leaving the sustain elecfrode (lla), creating a plasma glow, and plating out around the other sustain electrode (1 lb). The only way electrons will be plated out around any elecfrode is if a high enough electric field exists to ignite the plasma and create ionization/electrons. Therefore, if the pixel is written then electrons are plated out on the top of the plasma channel 35 and can be used to address the electro-optic material. One potential problem with this second addressing scheme is that the electrons are plated out locally around one of the two sustain electrodes, 1 la or 1 lb, depending on which phase of the AC was last used. This local collection of electrons may result in incomplete addressing of the electro-optic material 37 because of the non-uniform electric field through the electro-optic material 37. One method of combating this problem is to use adjacent pairs of sustain electrodes as single sets of sustain electrodes. Combining the sustain electrodes can be done by simply tying each pair of sustain electrodes lla and 1 lb together and use them as a single sustain electrode (lla). The second sustain electrode (1 lb) will result by tying an adjacent sustain electrode pair together. Using an interlaced addressing technique will be the best method of addressing the entire display, since each fiber 17 only contains one of the sustain electrodes. However, tying the two sustain electrodes l la and 1 lb together will allow for the plasma to spread over the top of the plasma channel 35 in the bottom fiber 27 below and between the sustain electrodes lla and 1 lb. These electrons can them be used to address the elecfro-optic material 37. One potential difficulty in fabricating these complex-shaped fibers is maintaining the tight tolerances and holding the exact shapes. A lost glass or lost plastic process is optionally used to create the exact desired shape, as shown in Figure 30A and 3 OB. In this example, an etchable or dissolvable material 95 is added to the preform before the fiber draw, to maintain the thin narrow vertical ribs 90 and hold the top of the plasma channel 35 as flat as possible. Figures 30A and 30B also show a contoured glass membrane 39P around the plasma address electrodes 36. This contoured membrane 39P creates a more uniform field upon addressing, and creates a larger surface area for free carrier annihilation after plasma discharge. Figure 31 A shows that the plasma within the tubes could be ignited using electrodes 36el .and 36e2 at the ends of the tubes 27. In this case, the drawn-in wire elecfrodes are replaced with two electrodes at each end of the plasma tube. Elecfrodes 36el and 36e2 at the ends of the plasma tubes will only be useful in larger tubes since the firing voltage will be too high in small tubes as a result of wall quenching of the ionized gas. The tubes can be sealed at the ends by using a glass sealing frit or by locally heating the tube while the inside is at a lower pressure, hence collapsing the tube 88 onto itself and sealing it off. The ribs 90 to support the electro-optic material could also be designed into the tubes and electrodes 36 sealed into the ends, as shown in Figure 3 IB. Figure 32 represents a fiber-based display that can be operated in both a transmissive and reflective mode, referred to as a transflective mode. The display has an array of bottom fibers 27 that have plasma tubes 35 to address the electro-optic material by plating out charge like stated above, however since the display has to work in a transmissive mode the fibers 27 have to be clear or translucent. The top fibers 17 have at least three sets of electrodes and a channel for the electro-optic material 37. The two set of side electrodes 33a and 33b are used to address the elecfro-optic material in the plane of the display and electrode 31 is used to modulate the elecfro-optic material 37 using the charge from the plasma 35 similar to that discussed above. It will be beneficial to design a black matrix 52 into the top fiber 17 as shown in Figure 33 A. This black matrix will create a sharper image and block the light not going through the electro-optic material. In addition, a reflective layer 51 could be added to the bottom of the top fiber 17. This reflective layer 51 could be included in the top fiber 17 or could be coated on the surface of the fiber. If the top fiber 17 is composed of glass the bottom of the fiber could be composed of an opal glass, which will reflect the light, but also let some of the light pass through. It would be preferred to fabricate the top fiber 17 out of plastic because of weight and ease of formation. If a polymer material is used to fabricate the top fiber 17 a reflective material could be used that would allow light to pass through if coming from underneath but reflect light coming through the electro-optic material. A coating could also be applied to the fiber preferably on the outer surface. This coating could act similar to a one-way mirror, where light coming through the fiber is reflected, however light coming from underneath is passed through. The two preferred electro-optic materials 37 for the transflective display are the bichromal sphere (Gyricon) and electrophoretic material. One potential operation of the display using an electrophoretic material is to fill the electro-optic channel with a dilute solution of absorbing particles 37p in a colored or clear liquid. Then by applying a voltage between electrodes 33a and 33b the absorbing particles 37p will move through the liquid to one of the two contact, as shown in Figure 33B. Moving the absorbing particles to one of the two electrodes, 33a or 33b, will open-up the center region of the top fiber 17 for light to pass through. Assuming the display is being back-lit then the light can pass directly through the display. If the display is being operated in a reflective mode and there is a reflective material 51 on the bottom side of the top fiber 17 or the bottom fiber 27 is reflective then light traveling through the display will be reflected back out of the display. If color is desired then either the top fiber can be coated with a color die, or be composed of a colored material, or the electrophoretic liquid solution could be colored. To change the gray scale of the display or make it dark the absorbing particles 37p can be moved to the bottom of the elecfro-optic cell region, as shown in Figure 33C. The absorbing particles can be attracted to this surface by addressing the display using the plasma channel 35 and the addressing electrode 31 as discussed above. Voltages could also be applied to the side electrodes 33a and 33b to create the proper electric field to assist in moving the absorbing particles to the bottom of the electro-optic cell region 37. Gray scale can be achieved by only moving part of the absorbing particles 37p to the bottom of the electro-optic cell region 37. Creating a transflective display using bichromal spheres is similar in operation to that using electrophoretic materials except that bichromal spheres are only rotated and not translated. Figure 33D shows one potential position of the bichromal spheres when a voltage is applied in the plane of the display or between elecfrodes 33 a and 33b. In this example the bichromal spheres 37b are clear or colored with an absorbing material in a slice through the center of the sphere. When light passes through the display it is effected little by the spheres 37b since the light is travelling in the same direction as the plane of the absorbing layer. Color could be added to the fiber 17 as discussed above or it could be added to the spheres 37b. The color could also be added to the liquid solution or polymer material that suspends or holds the spheres 37b in the elecfro-optic region 37. Changing the gray scale is achieved by addressing the pixel using the plasma channel 35 and the electro-optic address electrode 31 as discussed above. Different levels of gray scale can be achieved by only rotating some of the spheres or by rotating them to a given angle. Figures 34 and 35 represent two types of bichromal spheres that can be used as an elecfro-optic material. Figure 34A shows a bichromal sphere 37b where one half of the ball is black and the other half white. The bichromal sphere is composed of two dissimilar materials that have two different zeta potentials, which generate positive and negative surface charges when placed in contact with a liquid. These different surface charges are what makes the bichromal spheres rotate when placed in an electric field. Figure 35A shows a bipolar sphere 37b with a center light absorbing or reflecting medium 52b sandwiched between two dissimilar materials with different dielectric constants kl and k2. If one of the two dielectric constant materials kl or k2 changes with respect to an applied electric field then the bipolar sphere 37b can be rotated with respect to the direction of the electric field and the frequency of the electric field as described in US Patent 4,261,653. In order to rotate either of the bichromal spheres in Figures 34A or 34b they need to be floating in a fluid. Figures 34B and 35B show that a sac 73 can be created around the spheres 37b and a fluid 74 can be filled between the sphere 37b and the sac 73. The sac 73 around the sphere 37b can be formed using the traditional method of coating the spheres 37b with a polymer film 73 and then swelling the film with a plasticizer to form a void around that sphere 37b that can be subsequently filled with an oil 74. Another method of creating the sac 73 around the sphere 37b is to coat the sphere 37b with a sacrificial film and overcoat the sacrificial film with the sac 73. Then by using a thermal or chemical process the sacrificial film can be removed leaving a void to be filled with a lubricating fluid 74. These fluid 74 filled sacs 73 of spheres 37b can then be placed in a clear polymer film 75 to form a sheet of twisting ball material, as shown in Figure 36. One advantage of starting with fluid 74 filled sacs 73 of spheres 37b is that a non- permeable polymer film 75 can be used to house the twisting ball material 37 such that no fluid can penetrate to the surface of the film, thus allowing for the fabrication of electronic paper. Figure 37 illustrates a method of designing electronics to address the display using a rotating wiper blade 92 to sequentially add the high voltages to the electrodes (el through e(n-l)) of the display. The high voltages can be applied to each line (el through e(n-l)) of the display using a single transistor 96 attached to the rotating wiper blade 92. Using one high voltage transistor 96 to address each line of the display will result in a very large cost reduction over using a high voltage transistor 96 for each line of the display. Since the plasma electrodes are sequentially addressed in the above mentioned elecfro- optic displays this type of addressing electronics would very suitable to address those displays. Another sequentially addressing drive mechanism would be a linear drive where the wiper blade 92 is translated along a line of elecfrodes (el through e(n-l)) sequentially making contact and addressing each electrode using a high voltage transistor 96 attached to the wiper blade 92. A further embodiment of the invention includes the use of fibers mainly in the form of hollow tubes with wire electrodes .and barriers to construct reflective fiber-based displays. Modulating an elecfro-optic material within the display forms the reflectivity. The wire electrodes are contained within the fiber or on the surface of the fiber. The barriers are either structural barrier walls or created by an electric field from a wire electrode and assist in matrix addressing the display. The fibers or tubes are optionally colored to impart color to the display and can also be partially black to serve a black matrix function which enhances the contrast and sharpness of the display. Alternatively, the fibers or tubes can be white to enhance the reflectivity of the display. The elecfrophoretic material may also be colored to add color to the display. The fibers or tubes are preferably composed of glass, glass ceramic, plastic/polymer, metal, or a combination of the above. Figure 38 shows a schematic of a structural barrier type in plane switching electrophoretic display using hollow tubes 127 containing barrier walls 168 and wire drive electrodes 163. The height of the physical barrier wall 168 extends less than 100% of the height of the inside of the hollow tube 127, leaving a gap between the barrier wall 168 and the top of the hollow tube 127. The array of tubes 127 are sandwiched between two plates 160T and 160B. The top plate 160T has parallel address electrodes 161 to modulate the flow of electrophoretic particles 137 in the hollow tubes 127. The bottom plate 160B is blanket coated with a second planar drive electrode 162, which is used to attract the particles to the bottom of the hollow tubes 127. Addressing the display is accomplished by applying voltages on the wire drive electrodes 163 and the address electrodes 161 to create an electric field to force the elecfrophoretic particles 137 to flow over the barrier walls 168, if the pixel is to be dark (a written state). Figure 39 shows typical voltage waveforms to address a pixel in the display. The three periods of addressing, the refresh period, the write period and the hold period, are pictorially represented in Figures 40A, 40B, .and 40C, respectively. The voltage pulses and representative figures assume that the electrophoretic particles are positively charged. During the refresh period a negative holding voltage, -V , is applied to the wire drive electrode 163 to attract the particles 137 and a positive refresh voltage, +V f , is applied to the planar drive electrode 162 to repel the particles 137. Under these voltage conditions, the particles 137 collect around the wire drive electrode 163, as shown in Figure 40A. To place the pixel in a written state, particles must flow over the barrier wall and be collected on the surface of the hollow tube. This flow of particles is accomplished by applying a positive repulsive voltage, +V r , to the wire drive electrode 163 to repel the particles 137 from the wire drive electrode 163. A second positive write voltage, +V W , is applied to the orthogonal address electrode(s) 161 to control the flow of particles 137 over the barrier wall 168, as shown in Figure 40B. The magnitude of the write voltage, +V W , determines if the particles 137 flow over the barrier wall 168 or not. If a large write voltage, ++V W , is applied to the address electrode 161, then the particles 137 are forced to stay below the barrier wall 168 and the cell is in an unwritten state. Whereas, if a small write voltage, +V W , is applied, then the positive voltage from the wire drive electrode 163, +V r , creates a large enough repulsive field to force the particles 137 to flow over the barrier wall 168. A negative voltage, -V h , is also applied to the planar drive electrode 162 to attract the particles 137 that flow over the barrier wall 168 to the bottom of the hollow tube(s) 127, as shown in Figure 40C. Once the cell has been written (or not), the voltage on the wire drive electrode 163 is reduced to a negative holding voltage, -V h , to attract any remaining particles 137 that have not made it over the barrier wall 168 and allow the next hollow tube 127 row of the display to be addressed. The address voltages, +V W , are then modulated to address the subsequent rows (hollow tubes) in the displays. Note that the planar drive elecfrode 162 stays at a negative hold voltage, -V h , until the remainder of the display is written .and the display is ready to be refreshed. Gray scale images are optionally created in the display by controlling the write voltage, +V W , on the address elecfrode 161. Controlling the magnitude of this voltage controls the strength of the repulsive electric field, hence controlling the amount of particles 137 that flow over the barrier wall(s) 168. Reducing the magnitude of the write voltage, +V W , on the address electrode 161 in turn leads to an increased number of particles that surmount the barrier wall(s) 168. Another method of creating a gray scale image divides the addressing time into sections or bits, similar to the addressing scheme of a plasma display. The amount of time that the write voltage, +V W , on the address electrode 161 is reduced to near zero voltage during the addressing period of a single frame determines the amount of particles 137 that flow over the barrier wall(s) 618. In a preferred embodiment, this time modulating addressing scheme is combined with a JPEG image and the image on the display is written similar to the flow of information from a JPEG image (i.e. the image is written in an intensity map sequence). A third method of creating gray scale breaks the address electrode 161 into several electrodes, similar to that shown in Figure 48D. The multiple address electrodes can have different widths to control the flow of particles from a larger area. The barrier wall 168 in the hollow tube(s) 127 may be replaced with a barrier electrode 169, similar to that shown in Figure 41. This barrier elecfrode 169 serves the same purpose as the barrier wall 168 discussed above. The barrier is created by applying a positive voltage to the barrier electrode 169 in turn creating a repulsive barrier for the particles to cross over. The size or height of the barrier is determined by the magnitude of the voltage applied to the barrier electrode 169. The barrier wall 168 and barrier elecfrode 69 can both be combined into one hollow tube 127 to create a compound barrier, as shown in Figure 42. This compound barrier yields a much tighter control on the movement of particles 137 across the barrier region. The barrier electrode 169 can be combined with the barrier wall 168 at any location within the barrier wall 168. Figure 43 shows a cross-section of a hollow tube 127 where the barrier is a gate created by a barrier electrode 169 and a control electrode 171. There are two different methods of operating this type of barrier. The first method creates a gate using the barrier electrode 169 and the control electrode 171. This gate is large enough to keep any particles 137 from passing through it. Then, by applying a negative voltage on the orthogonal address electrode(s) 161 (not shown, see Figure 38), the gate is locally reduced and particles 137 can pass through it. The other method uses the barrier elecfrode 169 and control elecfrode 171 to create a gate weak enough for particles 137 to penetrate through it. Then, by applying a positive voltage on the orthogonal address elecfrode(s) 161 the gate can be selectively closed to particle.137 flow. The wire drive electrode 163 can be attached to the sides of the hollow tube between the barrier elecfrode 169 and the control electrode 171 so the particles have a more direct line of sight to the center of the electrostatic gate. Figure 44 shows a gate that is created using the barrier wall 168 and a control electrode 171. Figure 44 A shows the control electrode 171 located directly above the barrier wall 168 and Figure 44B shows the control elecfrode 171 in the corner of the hollow tube 127. Adding a control electrode 171 allows for many different addressing schemes. But, the largest advantage of adding a control electrode 171 is to even out the particles 137 along the length of the hollow tube 127. During the operation of the display, particles start to aggregate to one location in the hollow tube as the image in that area of the display is continuously written dark. Applying an alternating voltage between the control electrode 171 and the wire drive electrode 163 evenly redistributes the particles. This reconditioning of the distribution of particles is imperative for a display with an even gray scale and color distribution across the display. In addition, the control electrode 171 greatly assists in returning the particles to the wire drive electrode 163. Due to the blocking of the barrier wall, applying a negative voltage to the control electrode 171 pulls the particles 137 from the large volume of the hollow tube 127 much easier than applying the voltage to the wire drive electrode 163. In order to increase the contrast of the display, light absorbing regions 175 must be added to the sides of the hollow tubes 127, as shown in Figure 45. These light absorbing regions 175 function as a black matrix and keep light from penetrating through the unmodulated regions of the display. Figure 45 A shows that the black absorbing region 175 is contained within the hollow tube 127. Alternatively, the black absorbing region 175 is coated on the ends of the hollow tube 127, as shown in Figure 45B. Both Figures 45A and 45B block the unwanted light within the hollow tube, but light still can be transmitted between the hollow tubes 127 if they are not in intimate contact. However, by designing the hollow tubes 127 in .an interlocking mechanism or simply slanting the side of the hollow tubes 127, similar to that shown in Figure 45C, the light transmission between the hollow tubes 127 is blocked. Figure 46 shows several ways to add color to the display. Color is added to the display by fabricating the hollow tubes (127R, 127G, 127B) from a color material, as shown in Figure 46A, or by coating the hollow tubes with a colored die. The color die is coated on either the inside or outside of the hollow tubes. The colored die and/or black matrix can be coated on the tubes (127R, 127G, 127B) during the draw process. This can be done using several different methods, the most promising method being spraying or drawing the tubes (127R, 127G, 127B) over or past a coating system. Coating the tubes (127R, 127G, 127B) with both the black matrix material 175 and color filter material requires two different coating systems. The first system coats the sides with an absorbing black matrix material 175, while the second system coats the top, bottom or both top and bottom with a particular color film (red, green, or blue) to create the color in the display. Color can also be added to the display by either making the particles (137R, 137G, 137B) different colors in the hollow tubes, as shown in Figure 46B, or by making the liquid medium the particles 137 reside in colored. To achieve the best color quality in the display, both the hollow tubes (127R, 127G, 127B) and electrophoretic particles (137R, 137B, 137G) have to be colored, as shown in Figure 46C. Reflectivity in the display is achieved by using a reflective conductive planar drive elecfrode 162, shown in Figure 38. Using a highly reflective metal film for this electrode 162 yields a high reflectivity, however the display only functions in a reflective mode. To fabricate a transflective display that can be operated in both a reflective and transmissive mode, the reflecting material must be both fransmissive and reflective. An example of one such material is a conductive coating that is used in a one-way mirror, where the mirror side faces the viewer. Therefore, when there is a high level of incident light on the display, it functions in a reflective mode, but when the background illumination level is low, the display is back illuminated and functions in a transmissive mode. The reflectivity of the display can also be included in the hollow tubes 127, as shown in Figure 47. Figure 47A shows the reflective layer 177 as part of the hollow tube 127. If the hollow tube 127 is composed of glass, this reflective layer 177 is preferably an opal glass. Alternatively, if the hollow tube is composed of plastic, then white pigment or colorant could be added to the polymer blend to form the hollow tube(s) 127. The reflective layer 177 could also be added to the surface of the hollow tube 127, as shown in Figure 47B. This reflective coating 177 could be a simple white paint and/or could be conductive and serve as the planar drive electrode 162. In order to create very large displays, it is advantageous to replace the patterned address elecfrodes 161 on the top plate 160T with wire address electrodes 161 W, as shown in Figure 48. Figure 48 A shows a cross-section of a typical patterned top plate 160T with the transparent address electrodes 161, similar to that shown in Figure 38. These address elecfrodes 161 are replaced with an array of wires 161W, as shown in Figure 48B. One potential problem with using individual wires as the address electrodes 161 W is holding the wires on a given pitch or separation. To alleviate this problem, the wires are held in the exact location by adding a transparent flowable film between the top plate 160T and the hollow tubes 127. This flowable film not only holds the wire address electrodes 161 W in place but also removes the light reflection at that interface. Another method to maintain the correct pitch is to include the wire address electrodes 161W in a fiber similar to that shown in Figure 48C. In this case, arraying the fibers 117 into a compact sheet places the wire address electrodes 161 W on a specified pitch. Since the wire is made as thin as possible to allow for the maximum amount of light to be transmitted through the display, the electric field created by the wire is narrow. One potential solution to this problem is to add more than one wire address elecfrode 161W per fiber 117, as shown in Figure 48D. Multiple wire electrodes 161 W spread out the electric field and the thin or small diameter of the wire minimizes the obstruction of light passing through the display. Another potential problem with fabricating a high quality reflective display is the reflection at the interfaces between the plates 160 and the hollow tubes 127 or fibers 117. These additional surfaces create reflections, which lowers the contrast ratio of the display. To reduce or eliminate these reflections, a flowable polymer material is optionally included into the structure between the plates 160 and the hollow tubes 127 or fibers 117. A polymer material, such as, for example, ethylvinyl acetate (EVA), is optionally used to remove these reflections. In addition, it is advantageous to match the index of refraction of the plates, fibers/tubes, and electrophoretic solution to reduce reflections. To fabricate the hollow tubes 127 and fibers 117, larger size preforms 227 are drawn into smaller sizes 127, as shown in Figure 49 A. The art of including the wire electrodes and forming the arrays of hollow tubes 127 or fibers 117 is explained in copending U.S. Application Serial Number 09/299,350, filed April 26, 1999, entitled "PROCESS FOR MAKING ARRAY OF FIBERS USED IN FIBER-BASED PLASMA", which is hereby incorporated herein by reference. During the "fiber draw" process, the shape of the hollow tubes and barrier wall 168 is altered. This shape change is a result of forces exerted on the tube .and wall in reducing the size from a preform 227 to a hollow tube 127. The section of the "fiber draw" where the "fiber" is reduced in size is called the root of the draw. In the root of the draw, there are two normal forces that act on the "fiber". At the top of the root the force (FI) acts to pull all points to the centerline of the preform/fiber. This force (FI) is present until the root goes through the point of inflection (POI), the point at which the curvature of the root goes from concave outward to concave inward. The resulting change in shape of the hollow tube and barrier wall 168 is shown in Figure 49B, a cross-sectional view of Figure 49A. Note that the force (FI) pulls the top of the barrier wall 168 and the sides of the hollow tube to the centerline of the cross-sectional shape. After the point of inflection, a force (F2) tends to "push" all parts of the preform/fiber away from the centerline. This force (F2) creates a final hollow tube and barrier wall 168 shape as shown in Figure 49C, a cross-sectional view of Figure 49 A. Note that the force (F2) pushes the top of the barrier wall 168 and the sides of the hollow tube outward from the centerline of the cross-sectional shape. By applying a small negative pressure or vacuum in the centerline of the hollow tube preform 227 during the draw process, the hollow tube 127 is kept from bowing outw.ard, however the barrier wall 168 is still tilted outward, similar to that shown in Figure 50A. Tilting of the barrier wall 168 during the draw process is advantageous in that it creates a better barrier for the electrophoretic particle 137 flow. Connecting the barrier wall 168 to the small square tube 164, housing the wire drive electrode 163, causes the barrier wall 168 to be bent over top of the wire drive electrode 163 during the draw process, as shown in Figure 50B. Figure 51 represents a method of placing the wire drive elecfrode 163 and barrier wall 168 in the top corner of the hollow tube 127 and the control electrode 171 in the bottom corner of the hollow tube 127. Addressing this type of display could be similar to that discussed above or the top plate 160T with address electrodes 161 (shown in Figure 38) could be placed below the hollow tubes 127 to replace the bottom plate 160B and planar drive electrode 162. The lines in the display are addressed along the length of the hollow tubes 127 by applying a voltage on the address electrode 161 and modulating the particle flow using the control electrode 171. In addition, the barrier wall 168 is optionally replaced with a barrier electrode, similar to that shown in Figure 43. Figure 52 shows the addition of a second wire drive electrode 173. Adding a second wire drive electrode 173 to the structure of the hollow tube 127 eliminates the need for the planar drive elecfrode 162 (shown in Figure 38). Using a second wire drive electrode 173 enhances the addressability of each row of hollow tubes 127 in the display by locally controlling the voltage in each hollow tube 127. Unfortunately, using a second wire drive electrode 173 instead of a planar drive electrode 162 localizes the field and tends to attract the electrophoretic particles 137 toward the second wire drive elecfrode 162. One method to spread out the electrophoretic particles once the cell has been written is to apply a high frequency AC voltage between the two wire drive electrodes 163 and 173. If this high frequency AC voltage is faster than the time it takes the electrophoretic particles 137 to traverse the hollow tubes 127 then it acts as an electronic shaker to spread out the particles. Another method which uses a second wire drive electrode 173 included in the structure of the hollow tubes 127 is to use multiple second wire drive electrodes 173, as shown in Figure 53. Placing multiple second wire drive electrodes 173 below the center of the hollow tube 127 spreads out the electric field and creates a more uniform attraction potential for the elecfrophoretic particles 137. As is obvious from the above examples there are several different methods of using fibers with wire elecfrodes to form a reflective display. The above figures are only used as an example and are not intended to limit the scope of using wire in fiber for reflective displays. Accordingly, it is to be understood that the embodiments of the invention herein described are merely illustrative of the application of the principles of the invention. Reference herein to details of the illustrated embodiments is not intended to limit the scope of the claims, which themselves recite those features regarded as essential to the invention.
