Description

200946956 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a method of manufacturing an electrowetting device, an apparatus for carrying out the method, and an electrowetting device manufactured according to the method. [Prior Art] A display device typically includes two substrates sealed together to form a hole. & The hole includes a display-display effect member. In the liquid crystal (LC) display φ * device towel, the member is a liquid crystal material. There are two common manufacturing methods for LC display devices. A first method is to arrange a pattern of a sealing material on a substrate, and attach a second substrate to the sealing material, thereby forming a hole between the two substrates. The aperture has an opening through which the aperture is filled with the LC material, typically under vacuum. A second method is known as the so-called titration injection method (〇ne-dr〇p fiIHng) in U.S. Patent Application Serial No. 2/5/94. It is provided with a closed sealing material pattern on a substrate to form a series of open containers. The 〇LC material was dispensed into each container. Attaching a second substrate to the sealing material encloses the granulator and forms a series of sealed holes filled with material. The y-page is precisely selected to avoid spillage or unfilling of the crater. The application of the 2nd display technology to the electrowetting device is a laborious method for operating devices that are low in yield and cannot be satisfied by seven people. In particular, when the device is a device that is filled with such holes, the filling of the holes generally results in an inability to achieve an acceptable level of performance. Accordingly, one of the aims is to provide an improved method of making a wet electrode assembly I36i24.doc 200946956, an apparatus for carrying out the method, and an improved electrowetting apparatus. [Summary of the Invention]

The object of the present invention is achieved by a method of manufacturing an electrowetting device comprising a first substrate, a second substrate and a sealing member, the method comprising a first step of applying a first fluid and a first a second fluid is applied to the first substrate, the first fluid and the second fluid are immiscible; a second subsequent step of attaching the sealing member to the first substrate; attaching the sealing member to the first substrate a step of forming the sealing member to form a hole surrounded by the first substrate, the second substrate and the sealing member, the hole containing the first fluid and the second fluid; curing the sealing member One step. In the final device, the sealing member is attached to both the first substrate and the second substrate. Among other things, the present invention relates to the order in which the sealing member is attached to the substrates and the other steps of producing the device. The method applies the first fluid and the second fluid to the first substrate prior to attaching the sealing member to the first substrate. The sealing member connects the first substrate and the second substrate in a prepared device. The holes containing the fluids are enclosed by the first substrate, the second substrate, and the sealing member. During the application of the first fluid and the second fluid to the first substrate, the [substrate is substantially free of obstacles such as protrusion of the sealing member. The obstacle affects the fluid dose of the substrate. When the surface of the first substrate is substantially flat, the fluid dose will only depend on the surface wettability and the characteristics of the two fluids, resulting in an accurate and reliable dose. 136124.doc 200946956: The method according to the invention makes it possible to better control the fluid dose by means of a substrate having a sealing member compared to the method of the prior art. The method according to the invention does not require the exact dose required for the titration injection method as in the prior art. The method is highly suitable for the manufacture of a hydro-wetting device, for example the second fluid is water and the first fluid can be one of the oil devices. The step of attaching the sealing member to the second substrate may be performed before or after applying the fluids to the first substrate. The curing Φ of the sealing member can be carried out after the two substrates are combined by the sealing member. Alternatively, by the delay of the curing action, an initiator such as radiation curing can be carried out prior to combining the substrates, the curing being carried out after the combination. This method is particularly suitable for the manufacture of electrowetting devices, such as lenses, optical filters, labs on wafers, and in particular electrowetting display devices. The two substrates enclosing a hole can form a display device comprising an image element or a plurality of pixel elements. ❹ In one particular embodiment of the electrowetting device, the first fluid can be applied to both substrates. In this case, it is preferred to apply the fluid to the two substrates before attaching the sealing member to the substrate. The method can also be used to manufacture an electrowetting device comprising three or more substrates, each of which is connected by a sealing member. After being filled and connected to the first two substrates by the method according to the present invention, the method can be used again. This pair of substrates is attached to the third substrate using this method. The first fluid can be applied to one or both of each pair of substrates. The sealing member can be attached to the second substrate before combining the first substrate and the second substrate, and the application has the following advantages: the sealing member can be in the absence of fluid Attached to the second substrate. The sealing member may be attached to the first substrate after the fluids are applied to the first substrate and before the two substrates are combined. The two substrates and the sealing member can also be combined in one operation.

The sealing member can be applied to the substrate in a specific pattern. This can be achieved by applying the self-injection material directly to the substrate from the injection II or by using screen printing. Alternatively, the sealing member can be a patterned sealing member, also known as a - sealing frame, fabricated prior to the attachment and having a predetermined pattern. The use of such a sealing frame simplifies the manufacture of the device, for example by using a patterned layer from one of the rollers. A particular embodiment of the patterned sealing member comprises, in the following order, a first layer of the sealing material, a carrier of the solid material, and a second layer of the sealing material. The layers of the sealing material and the carrier preferably have the form of the predetermined pattern. The carrier provides dimensional stability to the patterned sealing member to facilitate processing of the sealing material prior to application of the sealing material to the substrate. Since the carrier will "part of the final device, it will also help The two substrates are held at a prescribed distance. The sealing member between the substrates dissipates the W bait member by arranging the one patterned sealing member to the other, and the sealing member is constructed according to the lower jaw. The following sequence in g - 韶I* includes: a sealing material, a first loading, a sealing material, a second carrier, and a sealing material. The sealing member comprises a part of the process. The peeling layer may also contribute to the sealing structure having the pre-twist pattern. Preferably, the exfoliation layer is removed 136I24.doc -9- 200946956 shortly before combining the two substrates. The sealing material is not contaminated during the time between application of the patterned sealing member to the substrate and combination of the two substrates. The sealing member may also have a peeling layer on both sides. A peeling layer is removed prior to applying the sealing member to a substrate. Another peeling layer is removed before combining the two substrates. The method can include the step of forming a pattern in the sealing member. The pattern can be formed by any suitable means, preferably by laser cutting or die cutting. A pattern may be formed in the sealing material, the carrier, and/or the exfoliation layer. In the electrowetting device, the second fluid is preferably electrically conductive or polar, and the first substrate has a first surface area that is less wettable relative to the second fluid and is relatively permeable to the second fluid. Wetting one of the second surface regions 'The method includes the step of applying the sealing member to the second surface region. Applying the first fluid and the second fluid to the substrate

After the 'the first fluid will form a thin layer on the area that is less wettable with respect to the second fluid' and the second fluid will cover the thin and the substrate is adjacent to the second surface area, 埤, 埤A surface area is relatively wettable relative to the first fluid. When the sealing member is provided in the second surface region, the sealing material is in contact with the body and can be optimized to internalize the second fluid. Conversely, if the sealing member is applied to the := field: the sealing material will be in contact with the first fluid and the second fluid. It is difficult to form a sealing material that retains both the first fluid and the second fluid Z36124.doc 200946956 inside the cavity. In the case where the first fluid and the second streamer are oil and water, respectively, the sealing material is provided on the second surface region, the second surface region being relatively hydrophilic compared to the first surface region. " The rifle seal member is preferably bonded to the first substrate by bonding it to the first substrate via the first-second flow stratification layer.

胄 The sealing material can be bonded to the substrates by applying pressure to the sealing member ±. This pressure application system is particularly suitable for use in a reliable method of sealing electrical (4) devices. The sealing material can be cured by means of υν, applying an elevated temperature or using a chamber time as a separate curing step or combination (4). The method according to the present invention is particularly suitable for fabricating a plurality of electrowetting devices, wherein the first substrate is a co-inspection device, and the method includes the step of cutting the first substrate after forming the holes. The cutting of a broken glass substrate can be carried out by scribing and breaking. This (4) is usually carried out after curing the sealing material. The method can be used to fabricate a plurality of devices having a common first substrate and a separate plate. The method includes the steps of: - sealing member ' and each of the second substrate and the common first substrate group S for each device. The first substrate is cut after sealing. The process allows the shape of the second substrate to be different from the shape of the first substrate for scribing and breaking. The shape does not need to be passed through this method to create a plurality of devices having the same substrate and a total of 136124.doc -11 - 200946956 and the second substrate. The method comprises the steps of: providing a sealing member and a second substrate common to the devices; combining the common first substrate and the common second substrate; and cutting the first substrate and the second substrate. At least one of the steps of the methods is preferably carried out in a continuous process. For example, the first substrate, the second substrate, and/or the sealing member can be supplied from a roller. If the finished electrowetting device is wound on a wheel, the method can be further automated, thereby forming a roll-to-roll process.

Another aspect of the invention pertains to an apparatus for making an electrowetting device using the method of the present invention. The invention also relates to an electrowetting device comprising a first substrate and a second substrate, the first substrate and the second substrate being kneaded by a sealing member and forming a hole, the hole comprising a first fluid And a second conductive or polar fluid, the first fluid and the second fluid are immiscible, the first substrate has a first surface area that is less wettable relative to the second fluid, and is opposite to the second fluid One of the second surface regions may be wetted wherein the sealing member is disposed on the second surface region. The invention further relates to an electrowetting device comprising a first substrate and a second substrate, wherein the first substrate and the second substrate are combined by a sealing member and form a hole, the hole comprising a first fluid and a _ conductive or polar fluid, the first fluid and the second fluid being immiscible, the first substrate having a relatively non-wettable relative to the second fluid - a first surface region and relative to the second fluid One of the more wettable _Le-1 surface areas 'where the sealing member comprises a pressure sensitive adhesive. When the sealing material is a pressure sensitive adhesive, the sealing material is bonded by applying pressure, and γ 136124.doc -12- 200946956 is simply integrated into the method of manufacturing the electrowetting device. The sealing member may comprise a carrier of a solid material between two layers of sealing material forming a member having a suitably defined thickness. The first substrate of the 3H and the second substrate may have different shapes. Further features and advantages of the present invention will become apparent from the following description of the preferred embodiments. [Embodiment] ® 1 shows that two substrates are assembled according to the method of the present invention to form an electrowetting device. An embodiment of the electrowetting device is an electrowetting display device having four images of 7L. The electrowetting device includes a first fluid and a first fluid. The first fluid and the second fluid are immiscible. The first fluid is non-conductive and may, for example, be a hydrocarbon such as hexadecane or (polyoxy) oil. The first fluid is preferably opaque, but may be colored or white. The second fluid is electrically conductive or polar and may be water or a salt solution, such as a potassium hydride solution in a mixture of beta hydrazine and ethanol. The second fluid is preferably transparent, but may be colored, white, absorbing or reflective. Figure la shows a top view of the first substrate. The first substrate includes four first surface regions 2 that are less wettable relative to the second fluid and a second surface region 3 that is relatively wettable with the first fluid. The second surface area encloses the first surface areas. The four first surface areas correspond to the four image elements of the display device and are disposed in the - display area 4. When the first fluid is oil and the second fluid is water, the first surface area is hydrophobic and the second surface area is hydrophilic. 136124.doc •13· 200946956 The W, Bq 湿润 wettability characteristics of these surface areas can be obtained by appropriately selecting the base material, treating the surface of the substrate or applying a layer to the surface of the substrate. : For clarity, the surface areas are shown in the drawings as the substrate material provides the properties of the second surface region 3, the second surface region extending to the edge of the substrate i in FIG. For example, the first surface and the F & surface region can be formed by an amorphous fluoropolymer layer such as AF1600 or another low surface energy polymer. The hydrophobic hydrazine property preferentially bonds the first fluid to the first surface region because the wettability of the hydrophobic layer relative to the first fluid is higher than its wettability relative to the first fluid. The second surface region can be formed by a photoresist layer (Example: U8). Although the sealing member is attached to the substrate or the surface or surface region of the substrate or a fluid is applied to the substrate or a surface or surface region of the substrate, the substrate is considered to be disposed on the substrate. Any of the solid layers, such as the above-described layer 0 wettability which controls the wettability, refers to the relative affinity of a fluid to a solid surface. Wettability increases with increasing affinity, and it can be measured by the angle of contact formed between the fluid and the solid' and is advantageously measured within the fluid of interest. It is at a greater than 90. The relative non-wetability of the angle is increased when the contact angle is 〇. The complete wettability at this point is 0 at this contact angle. In this case, the fluid tends to form a film on the solid surface. Figure 1 b shows a top view of the second substrate 5. A sealing material is disposed on the substrate in a pre-twisted pattern, in this embodiment a square 6 having a shape enclosing one of the regions 136124.doc -14·200946956. A syringe is utilized to dispense the sealing material in accordance with the predetermined pattern. In order to avoid a situation in which the thickness of the material is uneven in the pattern due to the start of the injection, the injection preferably starts outside the display area, and then continues the injection toward the predetermined pattern. Alternatively, the sealing material can have a form that can be disposed on one of the sealing frames on the substrate. The figure shows a cross section of one of the two φ substrates before assembling the first substrate 丨 and the second substrate 5. The cross section shows the strips of the sealing material 6 in cross section along the line Α-Α» Figie in the circle la. The first substrate already has a first fluid 7, which is only adjacent to the first surface region 2. A method of applying the first fluid to the first substrate is to immerse the substrate in a bath of the second fluid, such as water. The first fluid, such as oil, is dispensed onto the surface of the substrate by a dispenser having an elongated opening adjacent the surface and submerged in the second fluid. The dispenser moves over the surface in a direction 垂直 perpendicular to the length of the opening. The first flow system is dispensed as a first fluid film over the length of the dispenser. Since the surface includes a first surface region that is more wettable relative to the wettability of the first fluid relative to the second fluid and a second wettable surface region that is higher in wettable relative to the second fluid The first fluid will preferentially abut the first surface regions without covering the second surface regions. When the above method for applying the first fluid is used, the step of combining the two substrates is preferably carried out in the second fluid bath. The second substrate 5 is placed in the bath, taking care to avoid trapping air under the substrate 136124.doc -15·200946956. The two substrates 1 and 5 are aligned and pressed together such that the two substrates achieve a desired mutual distance as shown in Figure Id. (4) The sealing material forms a sealing member 8 between the two substrates. The sealing member is between the two substrates. It is closed into a hole 9. The aperture includes the first fluid 7 adjacent the first surface regions 2 and the second fluid 1 捕 trapped in the aperture. The figures " are schematic 'expanded' for size. φ The seal 8 is formed on the second surface region 3, in this embodiment on the hydrophilic region. Since no first fluid is adjacent to this region, the sealed cavity side is only adjacent to the second fluid. Optimized selection of sealing materials for a fluid. If the seal is formed on one of the first regions, the first fluid will abut the lower portion of the seal and the second fluid will abut the upper portion of the seal. A relatively difficult system finds that it can withstand two distinct fluids, such as the first fluid and the second fluid. The sealing material 6 is preferably a pressure sensitive adhesive (PSA) such as commercially available from ❹3M. The material is bonded to the substrates under pressure application. The sealing member can be cured by applying UV light. The sealing member may have a thickness between 10 microns and 1 inch. It should be noted that contact with oil can degrade the adhesion of most pressure sensitive adhesives. The substrates may be made of, for example, glass or a polymer and may be rigid or flexible. The display device shown in FIG. 1D has a viewing side 12 and a rear side 13, and the viewing side 12 can view an image or display formed by the display device. The first substrate 1 faces the rear side, and the second substrate 5 faces the viewing side 12°. In an alternative embodiment, the display can be viewed from the rear side 13. The 136124.doc • 16 - 200946956 display unit can be reflective, transmissive or transflective. The position of the first fluid 7 on the first surface region 2 can be controlled by an electric field applied to an electrode not shown in the figure. Details of the operation of the electrodes and the sigma apparatus are described in International Patent Application No. W003/071346.

Figure 2 shows two different embodiments of a sealing member in the form of a sealing frame. The sealing frame can be applied to a substrate in a different manner than the above method using a syringe. Figure 2 & shows a cross section of a sealing member 15. The sealing frame comprises a layer 16 of sealing material having a predetermined shape that seals the sub-hole S of the device. The sealing frame may have a peeling layer 17 on one side, as shown in the figure, but may also be provided on both sides. The spalling layer provides strength to the sealing frame, aids in processing the sealing frame and enables the sealing frame to be stored on a roller. The peeling layer must be removed from the sealing material prior to bonding the two substrates. The spalling layer can be removed while the sealing frame is submerged in the second fluid bath shortly before the two substrates are to be bonded. The peeling layer may have the predetermined shape, but it may also be a sheet or strip without the predetermined shape. The '3 q-stranded bamboo, for example, one of the polymers 21 such as PET, has two layers of sealing materials 19 and 20 on both sides. The seal (four) and the (four) have the shape of the crucible. The sealing frame can have a peeling layer 22, indicated by a dashed line. The thickness of each layer of the sealing material can be 25 microns and the thickness of the carrier can be 25 microns. In the procedure for manufacturing the electrowetting device, this can be used. The second substrate 5 is bonded to 136124.doc -17- 200946956 before the first substrate 1 is attached, the sealing member 15 or the sealing frame 18 is attached to the second substrate. The cross-section of the substrate 丨 and 5 before bonding is similar to that shown in Figure lc. Alternatively, the sealing frame may be attached to the first substrate after the fluid is applied to the first substrate. The cross section of the substrate before bonding is shown in Figure 3a. It is also possible to align the sealing member between the two substrates and press the two substrates together with the sealing frame, as shown in FIG. The sealing frames can be used in a device for carrying out the method according to the invention

Pre-made into the predetermined pattern. The sealing frames may be separate sealing frames to be picked up by the storage area, or they may be joined by the peeling layers to form a roll of tape. Alternatively, the sealing frames can be cut as part of the manufacturing process. In order to achieve this, the device requires H, and the sealing frame is cut by a laser or a die. The patterned seal frame is transported from the table to a table where the substrates are joined. The method of making the electrowetting device in accordance with the present invention is highly suitable for fabricating a plurality of electrowetting devices on a military substrate. Figure 4 shows a cross-sectional and top view of a plurality of devices on a single substrate. The number of devices shown in this embodiment is twelve, constituting three columns, four devices per column. For each of the twelve devices 26, the first substrate 25 has a first surface area and a second surface area. Figure #' is similar to Figure u. The surface area 27 between the devices has the same wettability as the second surface area. The first substrate is used in common for each device, and each device (four) has its own second substrate 28. 136124.doc -18· 200946956 During the manufacturing process, the first fluid and the second fluid are applied to the first substrate 25. After aligning to the appropriate position of the first substrate, each of the equal soil plates 8 is then bonded to the first substrate. The sealing material 29 can be applied by any of the methods described above. When applied to the first substrate, each of the second substrates individually has the sealing material. When applied to the first substrate, the sealing material can be applied in a single round for all twelve devices. Preferably, the combination is in the H body bath. After the sealing member is cured, the first substrate is cut to separate the devices. When the first substrate is made of glass, the cutting will include a scribing and breaking procedure. Figure 5 shows a top view of one of a series of devices prior to cutting. The devices have a common first substrate 30 and a separate second substrate 31. The second substrate has a special form that is offset from the rectangle and can be relatively simple to manufacture: However, if the devices have a common second substrate, it is relatively difficult to fabricate such shapes, particularly when the cutting is required When scribing and breaking. The first substrate 31 may be curved, for example, to form the cavity into a dome shape. Figure 6 shows a cross-face and a top view of one of a plurality of devices having two substrates in common. The first substrate 35 has a pattern similar to one of the first surface area and the second surface area of the first substrate in FIG. After filling the fluids, a second substrate 36 is bonded to the first substrate. When the second substrate 36 is patterned by a color filter disposed on one of its surfaces, the two substrates must be aligned prior to bonding. The sealing material 37 can be applied to, for example, the first substrate or the second substrate in a single pattern. After the sealing member is cured, the first substrate and the second substrate 136124.doc • 19·200946956 are cut. The figure shows that the line 38' on the second substrate cuts the devices shown by the hatching from the substrate along the line 38. The process of making the earth-electric humidifier can be completely mechanized. Prior to performing the method according to the present invention, the first substrate is preferably applied to the surface of the substrate by electrodes, electronic devices, and any optical layer such as for reflection, absorption or transmission, and the like. The wettability characteristics required for the surface area. Similarly, the second substrate should have any desired layer 'e. When the components to be disconnected (e.g., the substrate and the sealing member) are operated, the components can be picked up and assembled by a pick-and-place machine according to the method.

During the filling step, the two tapes are made The distance between 49 and 54 is sufficiently large for a dispenser to pass over the first substrate to dispense a first fluid onto the first substrate. For clarity, the dispenser is not shown in the figure. After the filling step, the second substrate and the first substrate are aligned and in close contact. In the bonding step, the two substrates are pressed together and the seal between the two substrates is cured to form an assembled device.
