Prior art Commercially, it is highly desirable for electronic display devices to be as thin and light as possible while maintaining a high resistance to vibration and falling forces. In the field of mobile electronics, such as mobile phones and personal digital assistants (PDAs), size < and weight \ key to the success of product marketing, but the display barrier in these devices is the main factor for product repair and recovery . In addition, it has been known here that electronic display devices that can be bent: the so-called "electronic paper" that displays fiber paper of 2 miles and 3 miles will be a competitive product. If folded, wearable electronic products such as computers or multi-function watches will be more comfortable for the wearer if they are more compliant with the user ’s body; chip cards with strict flexible life testing capabilities will The display unit is integrated and still meets these standards. In the field of display devices, there have been many years of in-depth research on the use of plastic films to remove glass. 〃 The electrophoretic display device forms an image through the principle of electrophoresis, and the electrophoretic particles quickly migrate in the gelatinous suspension. The light-scattering particles move in the dyed colloidal suspension due to static electricity. The particles are not moving towards the viewer (in this case, the viewer sees typical white particles), or they are moving away from the viewer (in this case, the white particles are covered by the black dye). Cholesteric display devices are another display technology intended for use on plastic substrates. When it is lost between the conductive electrodes, the cholesteric liquid crystal material can be switched between two stable states ~ the so-called focal cone (f〇cal coonic ιΜϋΙ ΙίΗ 1057-5245-PFl (N) .ptc 583476

The female hemisphere has a unique intrinsic charge, so that when the sphere is not aligned with the electric field, the side of the sphere that generates H ^ = on the sphere depends on the polarity of the voltage applied to the electrode. These three types of ΓίΓ have some good features, such as high contrast, slow response to plastics, and are not compatible with commercially available drive electronics. Also, because of the small driving voltage required for start-up (22), the electronic components are very easy to obtain and the investment in manufacturing technology = obvious advantages, so they are widely welcomed. Take two == ::. After assembling the display element, the polymer solids are separated and solidified. During the polymerization reaction, ^ will drop from the polymerization contact, 8 1 3 U.

Like other flexible display devices, pDLCDs require a high drive voltage S that is generally not compatible with current drive electronics. Conventional technology, such as US Patent No. 4, 688, 90 0, 5, 321, chat, 5, m, 271, country '434, 685'5, 504, 600'5, 53〇, 566, 5, 583,' '94 9'50 8 '5 '3 33'074 and No. 5,473,450' these 5 ί The phase of the LC / polymer mixture will be phase-separated during the polymer polymerization (photopolymerization) period 1 as the curing mechanism.

On the surface of the dream department with friction-aligned surface Ϊ Ϊ Structure 的 Display of nematic or electrically controlled birefringence (ECB) ^ 26, but it is difficult to form typical examples such as torsional nematic (TN) and super twist The structure that needs to align the surface on the two substrates is transferred to the second anti-shore period. The door is 3 * 450 and No. 5,3 33,074. It is described by light 1: i Several parts of the device come: standing polymer method. Although it can reach the pixel level of 毫米 3 mm = structure, it is more difficult to manufacture, because the photomask must show the electrode structure alignment, and usually an expensive calibration UV source must be used. Structures that must be less than 0.3 mm may be difficult to reach due to Lc / aggregation. U.S. Patent No. 5, 4-3, No. 450 teaches that the photo-initiator pattern is not transferred to the photo-initiator I net deposited on the substrate: it may be difficult to properly align the silk screen with the clear IT0 electrode However, the chemical substance ιιΐϋ 1057-5245-PFl (N) .ptc Page 7 583476 Λ_Ά Amended the case number 911228QR V. Description of the invention (4), negative directly on the surface of the polyimide alignment layer may cause Lc The alignment effect with the alignment surface is poor, the appearance of the display device is poor, and the yield is low. There are also other methods for providing adhesion between plastic substrates including adhesive components. In one method, a thermosetting (e.g. epoxy) or thermoplastic (e.g. thermosol) adhesive is used as a solid coating around the spacer element (U.S. Patent Nos. 4,678,284 and 5,130,831). Heat and pressure are applied after the coated spacer elements are located between the substrates. Other methods use solid-state adhesive elements spaced apart by π pieces (U.S. Patent No. 5 '812' 232 'No. 5,581,384 and No. 6,004,423). In addition to the factors that cause failure due to vibration and falling, the glass substrate Γ Γ device is difficult to use in an abnormal temperature environment. When the & cold and heat of the display device alternates, a gap may sometimes be created between the spacer element and the liquid crystal fluid. Although the gap is small, it is typically sufficient for the display device to be repaired. The gap is caused by the difference between LC and typical glass or plastic spacers. When the glass substrate display device is sealed at room temperature of -1 ", its volume will basically solidify at that time. With the display and cooling, the LC and spacer element materials will be closed = number: Γ Structural discontinuities between the spacer elements, the second force, the output, and the gift w :: At the beginning, the gap is a small vacuum pressure: low ', but more and more LC's volatile components change quickly = it will fill in It is full of voids and it is becoming lower and lower in energy balance. At room temperature, the steam that fills up the voids will prevent the voids from shrinking back to the ㈣men title exhibition.

Two important specifications that affect the durability of plastic display devices are their strength and peel strength. In addition, when the spacer element is of a single size and the two substrates in the ^ and 纟 fine cell are in contact, the compression is usually achieved when the spacer density is lower than ^ = degrees.

Liquid adhesives can have significantly better surface tack, elongation before breaking and tensile strength than solid adhesives. These efficacy parameters all determine how long the adhesive will bind. Other features and advantages of the present invention can be learned from the following detailed description and the scope of patent applications, as well as the following applications with the applicant, which are incorporated herein by reference: " "Photoelectric display device" (U.S. Patent Application No. 0 9/8 82 3 1 0 "Constructing an optoelectronic display device with an initial polymerization reaction and a reinforcing element between substrates" (U.S. Patent Application No. 09/882272); and '' An optoelectronic display device with a multilayer structure is achieved by different rates of polymerization and / or phase separation "(U.S. Patent Application No. 09/883 083). Embodiments According to the present invention, the assembly procedure of a liquid crystal display device is as follows: 1. The substrate is a flexible polymer with low birefringence that improves the optical quality of the final product and facilitates various drying and baking operations with a glass transition temperature greater than 50 t. The polymer system that meets these requirements is polyether Maple (PES). A gas barrier layer (vapor cbarrier) is coated on the outer surface of the substrate to improve the reliability and product life of the display.

Find a way to improve the bonding between glass and polymer at the glass / polymer interface through = pre-bonding, and improve the distribution of the polymer in silicon at the silane / polymer interface. 8. The spacer is mixed into the prepolymer at a concentration of about 1: 1 weight / weight. The spacer elements are distributed in the prepolymer using the ultrasonic mixing method. 9 · Use an aerosol spray system to spray a prepolymer / spacer element mixture on an uncoated substrate. The spray time is sufficient to achieve a surface density of at least about 30 spacer elements / square when the device is installed. Cm. The spacer elements are distributed substantially randomly across the substrate surface. As a propellant, finely filtered compressed nitrogen with about 0-30 PS1 was used. Adjust the pressure, the viscosity of the mixture, the relative concentration of the spacer element and the prepolymer, and the shape of the nozzle hole, so that a small amount of liquid containing only the prepolymer is applied to form a spacer element with a single coated prepolymer. The substrate was then placed under 120 t for 15 minutes to remove the solvent of the mixture. 10. A substrate with a pre-polymer / spacer element typically undergoes a pre-curing step to provide polymer-adhesive properties prior to the lamination step. If the prepolymer can be cured by heat and light, a solvent baking step can also be used as a precuring step. 1 1. Then laminate the substrates together, but keep the substrates properly aligned. 1 2. Then shine V light on both sides of the unit cell to break the photoinitiator and release free radicals around the spacer element. Polymerization was then focused on the starting position of each spacer element where the initiator was deposited. Figure 1 shows step 8 583476 Amendment No. 91122896 V.

U.S. Patent No. 192,284 (the content of which is incorporated herein by reference), the flexural force used for deflection is reduced without permanent damage. In all cases, the polymer form does not necessarily surround each spacer element, and the polymer does not necessarily extend completely from one substrate to another—for example, some spacer elements may not be coated with a prepolymer.

Description of the invention (13) The prepolymer covering the spacer element on the surface is pushed into the liquid crystal layer and pressed on the opposite substrate, as described in the previous embodiment. The semi-cured pSE is also pushed into the liquid crystal layer and compressed by the opposite substrate. pSE can be composed of polymers 'wherein the polymer has polymer optical properties similar to coated spacer elements' but can have different mechanical properties, for example PSE can be formulated to shrink upon curing and elongation before breaking parameters value. In this way, the plastic substrate can actually be pulled together to a certain degree of control after the laminated unit cells are completely cured. This significantly improves the flexibility of the display device and its overall financial performance. In yet another embodiment, the spacer elements are wrapped individually or in a stack in a rupturable shell, wherein the rupturable shell also contains a quantity of prepolymer. This can be achieved by a variety of conventional techniques commonly referred to as microencapsulation. Microencapsulation methods are divided into several categories, all of which are applicable to the present invention: interfacial polymerization, in-situ polymerization, physical methods (such as coextrusion), and coacervation. When the substrate is laminated with a liquid crystal material and a polymer-coated spacer (the above-mentioned cladding spacer), the microcapsules are crushed during the lamination to release the prepolymer. As described in other embodiments, the spacer element is pressed onto the two substrates during lamination, but the released prepolymer still surrounds the spacer element and contacts the two substrates. Then, the display device is irradiated with ultraviolet light in the manner described above, and the prepolymerized polymer is polymerized to produce a cured polymer that combines the spacer element and the two substrates. Although other microencapsulation techniques can be used to generate microencapsulations according to the appropriate features of the present invention, the two microencapsulation techniques that are particularly suitable for the present invention are in-situ polymerization and interfacial polymerization.

Description of the invention (14) The oil / water emulsion obtained by dispersing the substance in the water phase. Before emulsifying the prepolymer in the aqueous phase ', the spacer elements are mixed and completely dispersed in the prepolymer at a ratio of 1: 2 weight / weight. The emulsified prepolymer droplets have a diameter of 5-30 microns and the droplets contain less than 5 spacer elements. The purpose is to produce multiple capsules, each capsule having only one spacer element. More rigorous control of processing parameters can reduce the drop size error and minimize the number of capsules with more than one spacer element. By using spacer elements composed of materials having a different density from the prepolymer, such as glass, the number of capsules that do not contain a single spacer element can be minimized by, for example, selecting capsules by floating or centrifugation. The monomer is placed in the water phase and polymerized to form a polymer having an internal affinity greater than that of the water phase, thereby condensing the polymer around the emulsified oily droplets. In cases where it is particularly suitable for in-situ polymerization, urea and formaldehyde can condense in the presence of poly (acrylic acid) (see, for example, US Patent No. 400 1 14 0). The resulting cyst wall is a urea / formaldehyde mound polymer that surrounds the spacer element / prepolymer drip. The capsule is clear and rigid, and transparency is important because the capsule shell is still inside the display device after lamination. Rigidity is an important feature of the encapsulated shell, as a completely conformable shell material results in a shell that does not crush during lamination but properly releases the prepolymer. The shell material, which mainly contains melamine, also has the required transparency and rigidity. The optoelectronic material used for the display device may be any kind of liquid crystal. For example, the present invention is beneficial to nematic 'twisted nematicity, super-twisted nematicity, antiferroelectricity, cholesteric liquid crystal display device and the like.

Insert the spacer elements into the liquid crystal material, such as Merck ^ 7 (the density is sufficient to produce an apparent density of at least about 30 spacer elements / cm 2 when the display device is assembled). The spacer elements are distributed substantially randomly across the substrate surface. 7. Apply a thin layer of the liquid crystal / spacer element mixture to the polyimide surface.

In addition to adjusting aerosol parameters, also adjust the viscosity of the prepolymer formulation and, if necessary, dilute the prepolymer with a solvent so that the PSE particle size is greater than 30% of the spacer element diameter. The substrate was then left at 120 ° C for 15 minutes to remove the solvent of the mixture. 9. Substrates with prepolymer / spacer elements typically undergo a pre-curing step 'to provide polymer tackiness before the lamination step. If the prepolymer can be cured by heat and light, a solvent baking step can also be used as a precuring step. 1 0 · Then laminate the substrates together, but keep the I TO patterns on the substrates properly aligned. 11. The unit cell is then irradiated with uV light, which causes the photoinitiator to cleave and releases free radicals around the spacer element.
