Description of the invention: C: Technical field of inventions 3 FIELD OF THE INVENTION The present invention relates to a medium filling method for a multilayer cell, an electronic terminal and a multilayer cell 5, and more particularly to a medium such as a liquid crystal A technique of filling each layer of a multi-layer liquid crystal cell. C. The prior art is good; 1 Background of the Invention In recent years, the technical field of electronic paper that can be electrically rewritten 10 is rapidly developing even without a power supply. E-paper is currently being used to realize the ultra-low power consumption of the display even when the power is turned off, the reflective display that is soothing to the eyes without feeling tired, and the flexible display body that is flexible like paper. For the goal. In addition, research institutes such as companies and universities have been actively pursuing the development of electronic paper. The application market for electronic paper is expected to be ranked first in e-books (electronic books), and various application forms such as electronic newspapers or electronic advertisements, sub-displays for further communication terminals, and display portions of IC cards have been proposed. However, in the display mode of the electronic paper, the electric mobility mode in which the charged particles move in the air or in the liquid, the torsion electrode method in which the charged particles divided into two colors are rotated 20, or the double reflection stability by the interference reflection of the liquid crystal layer The development of the selective reflection type cholesteric liquid crystal method and the like continues. Among such various methods, it is advantageous to have an overwhelming color display on a color display. In addition to the cholesteric liquid crystal display method, it is necessary to apply a color filter of 3 colors in each pixel setting. Therefore, even if the brightness is maximum, it becomes equivalent to 1/3 of 3 parts, so it is not practical. In this regard, the cholesteric liquid crystal system uses the interference liquid crystal to reflect the color, so that it is possible to display the color 'with a brightness of 50% by the laminate layer. Thus, the electronic paper is regarded as a favorable cholesterol. The liquid crystal has semi-permanent display retention (memory), bright color display, high contrast and high resolution, and can also be used to present R (red), G (green) and B (blue) by stacking layers. The display layer of the reflective color reaches the full color display of the fresh disk. However, since the cholesteric liquid crystal has a memory liquid crystal, it is possible to carry out an inexpensive and simple rectangular drive, and for example, a large size of A4 or larger is also easy. Cholesterol-like liquid crystal consumes power only when the display content is rewritten (rewrites the image). 'After the rewriting of the image is finished', the power supply is turned off or the original is not sealed. In the present specification, the electronic paper which is multi-layered with R, G, and B cholesteric liquid crystals and can be displayed in full color is exemplified, but the multilayer cell (display image) of the present invention is not The electronic paper is limited to, for example, a multilayer cell which is formed by filling a plurality of layers (that is, two or more layers) of an electrochemistry photovoltaic cell, etc. First, a display to which the present invention is applied will be described. Examples of the driving conditions of the cholesteric liquid crystals of the examples. The alignment of the liquid crystals is shown in Fig. 1A and Fig. 1B for explaining the cholesterol state. Fig. 1A shows a parallel spiral state, and Fig. 1B shows a vertical spiral state. 1343491 Cholesterol-like liquid crystal can obtain two states of parallel spiral state and vertical spiral state without electric field. That is, as shown in Fig. 1A, in the parallel spiral state, the incident light system is reflected by liquid crystal, so the human eye The reflected light can be seen. 5 Further, as shown in Fig. 1B, in the vertical spiral state, the incident light passes through the liquid crystal. Moreover, in addition to the liquid crystal layer, light absorption is also provided. The layer, whereby the black color can be displayed in the vertical spiral state. In the parallel spiral state, the light of the wavelength corresponding to the helical pitch of the liquid crystal molecules is reflected, and the maximum wavelength of the reflection λ is the average yield of the liquid crystal. When η is such that the spiral pitch is ρ, it is expressed as η η ρ. Further, the reflected light band Δ λ becomes larger as the refractive index of the liquid crystal becomes Δη. The second figure and the second figure Fig. 2C shows a state in which the voltage characteristics (time-voltage relationship) of the cholesteric liquid crystal are driven, and the electric field applied to the liquid crystal changes with each of the vertical state, the vertical spiral state, and the parallel spiral state. Wherein, the vertical state is Η, the spiral vertical state is FC, and the parallel spiral state is Ρ. First, when a strong electric field is applied to the cholesteric liquid crystal, the spiral structure of the liquid crystal molecules is completely decomposed, and all the molecules become Follow the vertical state of the electric field direction Η. 20 As shown in Fig. 2, when the electric field jerk is zero from the vertical state, the helix axis of the liquid crystal will be perpendicular to the electrode and will become a parallel spiral state 可 that selectively reflects light in response to the helical pitch.
另一方面，如第2Α圖所示，當液晶分子之螺旋軸好不 容易分解之程度的弱電場形成後除去電場時，或者如第2C 7 圖所示，當施加，強的電場旅且緩慢地除去電場時，液晶的 螺旋軸會與電極平行’成為透過入射光之垂直螺旋狀態F(> 如此，膽固醇狀液晶為雙安定性’可利用該現象進行 情報的顯示。 第3圖係顯示膽固醇狀液晶的反射率特性（電壓與反射 率之間的關係），係將參照第2A圖〜第2C圖所說明之膽固醇 狀液晶的電壓應答性整理而加以顯示者。 如第3圖所不，當初期狀態為平行螺旋狀態p(第3圖之 左端之反射率高的部分）’當脈衝電壓上昇到某個範圍時， 會成為往垂直螺旋狀態FC(第3圖之反射率低的部分）之驅 動帶’進一步當脈衝電壓上昇時’會再次成為往平行螺旋 狀態P(右端之電壓高的部分）之驅動帶。 當初期狀態為垂直螺旋狀態FC(左端之反射率低的部 分）時’會隨著脈衝電壓上昇而慢慢成為往平行螺旋狀熊p 之驅動帶。 又，在平行螺旋狀態P時，僅反射右圓偏光或左圓偏 光，剩餘之圓偏光會透過，因此邏輯上反射率的最大值為 百分之50。 第4圖係概略顯示適用顯示元件之電子終端（顯示裝置） 之一例之區塊圖。第4圖中，參考符號丨係表示顯示元件（多 層晶胞）、3為電源電路、4為㈣電路、21為掃描側之驅動 益1C(掃描驅動$)，且22係表示資料側之驅動IC(資料驅動 器）。 如第4圖所示，電源電路3具有昇壓部31、電壓生成部 32及調整1133。Μ部31係由如電池触+3〜+5左右之輸入 電壓，並升壓成可驅動顯示元件1之電壓後供給到電壓生成 4 32電①生成部32分別對掃瞄驅動器21及資料驅動器22 生成必須之電壓，調整器33係絲自電壓生成部32之電壓 安定化後供給到掃瞄驅動器21及資料驅動器22。 控制電路4具有運算部4卜控制資料生成部42及畫面資 料生成部43。運算部41制以運算由外部供給之畫面資料 及控制信號，畫面資料係、經由畫面資料生成部43作為適合 顯不兀件1之貢料而供給到資料驅動器22，又，控制信號係 經由控制信號生成部42作為適合顯示元件丨之各種控制信 號而供給到知稱驅動器21及資料驅動器22。 其中，由控制信號生成部42供給到掃猫驅動器21及資 料驅動1§ 2 2之控制信號係如用以反轉控制供給到顯示元件 1之脈衝電壓之極性之脈衝極性控制信號CS2、用以表示1 框架之畫面開始之框架開始信號CS2、由資料驅動器22進行 用以儲存資料之資料線及掃瞄驅動器21所選之線之同步控 制之數據鎖存•掃描轉換信號CS4、及用以切斷資料驅動器 22及掃瞄驅動器21之驅動輸出之驅動輸出切斷信號CS5 等。又’由控制信號生成部42往資料驅動器22亦供給用依 序接收1線份之資料之資料接收時脈CS1。 第5圖係概略顯示第4圖所示之顯示元件（液晶顯示元 件：多層晶胞)之一部分的截面圖，且為表示1層（r，G，b之個 別之層）者。第5圖中，參考符號11及15係表示基板（膜基 板）、12及14係透明電極(例如ιτο)、13係液晶組成物(膽固 1343491 醇狀液晶）、16係驅動電路、且17係密封劑。 顯示元件1含有液晶組成物13，透明之基板11及15之内 面（封入液晶組成物13之面）分別形成垂直交叉之複數透明 電極12及14。即，於對向之基板11及15，複數之掃描電極 5 12及複數之資料電極14形成矩陣狀。又，第5圖中，乍看之 下，掃描電極12與資料電極14係呈平行，但實際上就是例 如複數之資料電及14與1支掃描電極12交叉。又，各基板u 及15的厚度例如0.2mm左右，又，液晶組成物13之層的厚 度係如3μιη〜6μπι，但為了說明則忽略該等比例。 10 其中，各電極12及14上，以塗覆絕緣性薄膜或配向安 定化膜者為佳。又，與使最下層（例如R層）之光入射之側相 反之相反側之基板（12)的下部（表面）可視需要而設置可视 光吸收層。又，液晶組成物13係如在室溫下顯示膽固醇狀 液晶相之膽固醇狀液晶.。 15 密封劑17係將液晶組成物13封入基板11及15之間者。 又，驅動電路16係用以對電極12及14施加預定之脈衝狀之 電壓者。 基板11及15可例示如玻璃基板，但除玻璃基板之外， 亦可使用PET或PC等可撓性樹脂膜基板。又，電極12及14 20 係以如ITO(Indium Tin Oxide :氧化銦錫）為代表，但除此之 外可使用如IZO(Indium Zic Oxide:氧化銦鋅）等透明導電 膜、或者鋁及二氧化矽等金屬電極，或者非晶矽、 BSO(Bismuth Silicon Oxide :)等光導電性膜。 第5圖所示之液晶顯示元件中，係如前所述，於透明犋On the other hand, as shown in Fig. 2, when the electric field is removed after the weak electric field of the liquid crystal molecule is not easily decomposed, or as shown in Fig. 2C, when applied, the strong electric field travels slowly. When the electric field is removed, the spiral axis of the liquid crystal is parallel to the electrode, and it becomes a vertical spiral state F through the incident light (> Thus, the cholesteric liquid crystal is double-stable), the information can be displayed by using this phenomenon. Fig. 3 shows the cholesterol The reflectance characteristic (the relationship between the voltage and the reflectance) of the liquid crystal is displayed by referring to the voltage responsiveness of the cholesteric liquid crystal described with reference to FIGS. 2A to 2C. As shown in FIG. 3, When the initial state is the parallel spiral state p (the portion where the reflectance at the left end of the third graph is high) "When the pulse voltage rises to a certain range, it becomes the vertical spiral state FC (the portion where the reflectance of the third graph is low) The driving band 'further when the pulse voltage rises' will become the driving band to the parallel spiral state P (the portion where the voltage at the right end is high). When the initial state is the vertical spiral state FC (the opposite of the left end) When the rate is low, it will gradually become the driving belt to the parallel spiral bear p as the pulse voltage rises. Also, in the parallel spiral state P, only the right circular polarization or the left circular polarization is reflected, and the remaining circularly polarized light The maximum value of the logical reflectance is 50%.

In Fig. 4, the reference symbol indicates Display element (multilayer cell), 3 is power supply circuit, 4 is (four) circuit, 21 is drive side drive benefit 1C (scan drive $), and 22 is data side drive IC (data drive). As shown in the figure, the power supply circuit 3 has a boosting unit 31, a voltage generating unit 32, and an adjustment 1133. The cymbal 31 is driven by an input voltage of about +3 to +5, and is boosted to drive the voltage of the display element 1. The supply voltage generator 4 32 generates a voltage necessary for the scan driver 21 and the data driver 22, and the voltage of the regulator 33 is stabilized from the voltage generating unit 32, and is supplied to the scan driver 21 and the data driver. 22.

The calculation unit 41 calculates a screen data and a control signal supplied from the outside, and the screen data system and the screen data generation unit 43 are suitable for display. The tribute of 1 is supplied to the data driver 22, and the control signal is supplied to the known driver 21 and the data driver 22 via the control signal generating unit 42 as various control signals suitable for the display element 。. The control signal supplied to the scan cat driver 21 and the data drive 1 § 2 2 is a pulse polarity control signal CS2 for inverting the polarity of the pulse voltage supplied to the display element 1, for indicating the start of the frame of the 1 frame.

The drive output of the drive 21 outputs a cutoff signal CS5 or the like. Further, the control signal generating unit 42 supplies the data receiving unit 22 with the data receiving clock CS1 for sequentially receiving the data of one line. Fig. 5 is a cross-sectional view schematically showing a part of a display element (liquid crystal display element: multi-layer cell) shown in Fig. 4, and is a layer showing one layer (a layer of r, G, and b). In Fig. 5, reference numerals 11 and 15 denote a substrate (film substrate), 12 and 14-type transparent electrodes (for example, ιτο), a 13-type liquid crystal composition (cholester 1343492 alcohol liquid crystal), a 16-series driving circuit, and 17 Sealant. The display element 1 contains a liquid crystal composition 13, and the inner surfaces of the transparent substrates 11 and 15 (the surface on which the liquid crystal composition 13 is sealed) form a plurality of transparent electrodes 12 and 14 which are vertically crossed. That is, in the opposite substrates 11 and 15, a plurality of scanning electrodes 5 12 and a plurality of data electrodes 14 are formed in a matrix. Further, in Fig. 5, at a glance, the scanning electrode 12 and the data electrode 14 are parallel, but actually, for example, a plurality of data electrodes and 14 and one scanning electrode 12 intersect. Further, the thickness of each of the substrates u and 15 is, for example, about 0.2 mm, and the thickness of the layer of the liquid crystal composition 13 is, for example, 3 μm to 6 μm, but the ratio is ignored for the sake of explanation. 10 In each of the electrodes 12 and 14, it is preferred to coat the insulating film or the alignment film. Further, a visible light absorbing layer may be provided as needed on the lower portion (surface) of the substrate (12) on the opposite side to the side on which the light of the lowermost layer (e.g., the R layer) is incident. Further, the liquid crystal composition 13 is a cholesteric liquid crystal which exhibits a cholesteric liquid crystal phase at room temperature. The sealant 17 seals the liquid crystal composition 13 between the substrates 11 and 15. Further, the drive circuit 16 is for applying a predetermined pulse-like voltage to the electrodes 12 and 14. The substrate 11 and 15 may be, for example, a glass substrate, but a flexible resin film substrate such as PET or PC may be used in addition to the glass substrate. Further, the electrodes 12 and 14 20 are represented by, for example, ITO (Indium Tin Oxide), but a transparent conductive film such as IZO (Indium Zic Oxide) or aluminum and two may be used.

At this time, the positional relationship between the media injection fields 118; 128; 138 and the barrier 119; 129a' 129b; 139 of each layer is as described with reference to FIG. Here, for example, in order to harden the sealants 117, 127, and 137 and the barrier 119; 5 129a, 129b; 139, it is necessary to heat or irradiate the ultraviolet rays before the medium (liquid crystal) is injected into each layer. Next, as shown in the middle diagram of Fig. 8, the B layer 101, the G layer 1〇2, and the R layer 103 in the empty state are joined by the adhesives 141, 142 without being separately injected into the medium, forming the right side as shown in Fig. 8. The multilayer cell of the figure. At this time, a coloring material such as a G-cut filter film that weakens a specific color (for example, green) is applied between the respective ten layers. Here, for example, in order to harden the adhesive 140 to strengthen the bonding of the respective layers 101, 102, 103, it is necessary to heat or irradiate ultraviolet rays, and the heating or irradiation of ultraviolet rays or the like may be performed before the medium is injected into each layer. Further, when the light absorbing layer is provided on the lower side of the R layer 1 〇 3 as described above, it is bonded and fixed at this stage using an adhesive or the like. Thus, a multilayer cell is formed before the medium is injected (filled) in each layer. Fig. 9 is a plan view of a multilayer cell formed by the preliminary steps of Fig. 8, and Fig. 9B is a view of the A-A line of the multilayer cell shown in Fig. 9A. 20 It is clear from FIGS. 9A and 9B that 'B layer 1 is bonded by the adhesives 141, 142 (H, G layer 102 and R layer 103, the B layer 101 corresponds to the green medium injection field 108 and the red medium is injected. There is a barrier 119 at the field 138. Further, in the G layer 102, there are barriers 129a and 129b' corresponding to the red medium injection field 138 and the blue medium injection field 118, and the R layer 1〇3 21 (§) 1343491 There is a barrier 139 corresponding to the blue medium injection field 118 and the green medium injection field 128. Fig. 10 is a plan view of the through hole of the multi-layer cell-injecting medium shown in Figs. 9A and 9B. Fig. 10B is a cross-sectional view taken along the line BB of the multilayer crystal cell shown in Fig. 10A. Further, Fig. 11A is a plan view showing the state in which the multilayer cell is injected into the medium as shown in Fig. 10A and the 苐jog diagram, section 11B. Figure CCA is a cross-sectional view of the multi-layer cell shown in Fig. 11A. As shown in Fig. 10A and Fig. 10B, the blue in the B layer 101 is filled with the medium 118 into the field 118 to form a through B, G, R Blue through holes 10 151 of layers 101, 102, 103. As shown in Figs. 11A and 11B, blue through holes 151 When the blue medium (blue cholesteric liquid crystal) is injected into the B layer 101 via the blue through hole 151, only the blue medium is injected into the B layer 101, and the other G layers 102 and R are added. In the layer 103, the blue dielectric medium is prevented from being interposed by the barrier 129b and 139. 15 Similarly, the green dielectric infusion hole 152 is formed in the green medium injection region 1 of the G layer 1〇2. The green through hole 152 is used. When the green medium (green cholesteric liquid crystal) is injected into the G layer 102 via the green through hole 152, only the green medium is injected into the G layer 102. For other r layers 103 and B, the barrier is used. 139 and 119 interfere with the injection of the green medium. Further, the red dielectric through-hole 153 is formed in the red medium injection region 138 of the R layer 103. The red through-hole 153 is configured to pass through the red through-hole 153. When the red medium (red cholesteric liquid crystal) is injected into the R layer 103, only the red medium is injected into the R layer 103, and the other B layers 22 1343491 101 and the G layer 102 are blocked by the red 119 by the barrier 119 and 129a. Injection When the blue medium, the green medium, and the red medium are injected (filled) into the B layer 101 'G layer 102 and the R layer 103, all of them can be simultaneously performed. Further, 5 each medium is injected into the corresponding through hole. The processing is disposed under the lower substrate 135 of the lowermost R layer 101 with a shielding member 160 such as silicone. Fig. 12 is a view showing an example of a medium injecting step in the medium filling method of the multilayer unit cell of the present invention. In Fig. 12, reference numeral 200 denotes a vacuum chamber, and further, the upper right multi-layer cell system corresponds to the 10A and 10B, and the lower right layer cell corresponds to the 11A and the 11B figure. As shown in the upper diagram of Fig. 12, the laminated multi-layer cell (empty cell) 1 is placed in the vacuum chamber 200 to make the chamber 200 a vacuum. Further, under the vacuum of the chamber 200, blue cholesterol liquid crystal, green cholesteric liquid crystal, and red cholesteric liquid crystal are injected (dropped) into the blue through hole 15151, the green through hole 152, and the red color. Through hole 153. Further, a shielding member 160 such as silicone rubber is disposed under the lowermost R layer 101. Further, as shown in the upper diagram of Fig. 12, by releasing the vacuum state in the chamber 200, blue cholesteric liquid crystal, green cholesteric liquid crystal, and red cholesteric liquid crystal are filled in the B layer 101, the G layer 102, and the R. Layer 103. Fig. 13 is a view showing another example of the medium injecting step in the medium filling method of the multilayer unit cell of the present invention. As is clear from the comparison between FIG. 13 and FIG. 12, in the medium filling method of the multilayer cell of the present embodiment, the multilayer cell shown in FIG. 12 is one unit (multilayer unit cell), and the two The multi-layer cell unit la and the lb-carrying rubber and the like are laminated, and the two multi-layer unit cells 13 and the crucible are injected into the medium 0. It is clear from Fig. 13 that the close-contact member 17 is corresponding to the through-hole. Holes are provided at the positions of 丨51, 152 and 153. Further, the number of stacked multi-layer unit cells 5 is of course not limited to two. As described above, according to the medium filling method of the multilayer unit cell of the present invention, since the liquid crystal cell is filled before the laminated liquid crystal is filled, the liquid crystal is filled in each of the unit cells, thereby preventing heating or irradiation such as hardening of the adhesive. The liquid crystal caused by ultraviolet rays is deteriorated. Moreover, according to the media filling method of the multi-layer cell of the present invention, since the liquid crystals of each of the cells are not contacted and mixed and can be filled at the same time, the multi-layer cell can be easily fabricated in a short time, and It can reduce the amount of excess liquid crystal during filling. Further, since a plurality of multi-layer cells (multiple multi-layer cell units) can be simultaneously filled with liquid crystal, a multi-layer cell can be easily fabricated in a shorter period of time. 15 The multi-layer unit cell of the present invention and the medium filling method for the multi-layer unit cell are mainly applied to an electronic paper having a plurality of layers (for example, R, G, and B layers) capable of displaying a full-color cholesteric liquid crystal, but is not limited thereto. Here, it can also be widely applied to a multilayer cell in which a plurality of layers of an electrochemistry photovoltaic cell are filled with a medium, respectively. 20 [Simple description of the diagram] Figure 1A is a diagram for explaining the alignment type of cholesteric liquid crystal (1).
