Abstract
Description
本發明是有關於一種面板，且特別是有關於一種電致變色面板。 This invention relates to a panel and, more particularly, to an electrochromic panel.
電致變色技術是藉由電場的作用，使具有電活性(Electroactive)的電致變色材料因發生電化學的氧化還原反應，而得失電子，從而造成可逆的顏色變化。近年來，電致變色技術被廣泛地應用在後視鏡、建築物的窗戶、汽車天窗以及顯示器等。以後視鏡為例，夜間行車時，來自後方車輛的光束投射至後視鏡所造成的鏡面反射往往造成駕駛人視覺的不適，甚至造成短暫的視覺喪失。即使強光消失，也會因視覺殘留而在駕駛人的視網膜上留有盲點，成為肇生事故的潛在危機。電致變色技術可藉由改變後視鏡所呈現的顏色來降低後視鏡的反射率，從而達到防眩光的效果。 The electrochromic technology is an electric field that causes an electroactive material to undergo an electrochemical redox reaction to generate and lose electrons, thereby causing a reversible color change. In recent years, electrochromic technology has been widely used in rearview mirrors, windows of buildings, sunroofs of automobiles, displays, and the like. In the case of a rear view mirror, when driving at night, the specular reflection caused by the light beam from the rear vehicle being projected to the rear view mirror often causes the driver's visual discomfort and even causes a short visual loss. Even if the glare disappears, there will be blind spots on the driver's retina due to visual residual, which is a potential crisis for twin accidents. Electrochromic technology can reduce the reflectivity of the mirror by changing the color of the mirror to achieve anti-glare effect.
目前電致變色面板主要的製作方式包括於兩片導電玻璃之間形成用以容納電致變色材料的間隙(cell gap)，然後將間隙抽真空，再將液態的電致變色材料灌注於間隙中。在將間隙抽真空 時，位於間隙上方的導電玻璃可能因內外壓力差而塌陷，造成間隙的厚度不均勻。如此，容易導致電致變色面板在顯示時產生彩虹紋(Mura)甚至牛頓環(Newton’s rings)的現象，從而嚴重影響電致變色面板的顯示品質。 At present, the main manufacturing method of the electrochromic panel comprises forming a cell gap between the two conductive glasses for accommodating the electrochromic material, and then vacuuming the gap, and then pouring the liquid electrochromic material into the gap. . Vacuuming the gap When the conductive glass located above the gap may collapse due to the pressure difference between the inside and the outside, the thickness of the gap is not uniform. Thus, it is easy to cause the phenomenon that the electrochromic panel generates rainbow lines (Mura) or even Newton's rings during display, thereby seriously affecting the display quality of the electrochromic panel.

圖1至圖7分別是依照本發明的第一至第七實施例的電致變色面板的示意圖。 1 to 7 are schematic views of electrochromic panels according to first to seventh embodiments of the present invention, respectively.
圖1是依照本發明的第一實施例的一種電致變色面板的示意圖。請參照圖1，電致變色面板100包括透光蓋板110、第一黏著層120以及電致變色薄膜130，其中電致變色薄膜130透過第一黏著層120貼附於透光蓋板110上。 1 is a schematic view of an electrochromic panel in accordance with a first embodiment of the present invention. Referring to FIG. 1 , the electrochromic panel 100 includes a transparent cover 110 , a first adhesive layer 120 , and an electrochromic film 130 . The electrochromic film 130 is attached to the transparent cover 110 through the first adhesive layer 120 . .
透光蓋板110的材質可選擇高機械強度以及具有抗刮能力的材質，以保護設置於其後方的元件(如電致變色薄膜130)。此外，透光蓋板110的材質可選擇具備高穿透率的材質，以利外界的光束L(例如照射至後照鏡的強光)自透光蓋板110入射進電致變色面板100，使入射進電致變色面板100的光束L可經由電致變色薄膜130的作用，而達到諸如降低鏡面反射或抗眩光的效果。舉例而言，透光蓋板110的材質可包括玻璃，但不限於此。 The material of the transparent cover plate 110 can be selected from a material having high mechanical strength and scratch resistance to protect components disposed behind it (such as the electrochromic film 130). In addition, the material of the transparent cover 110 can be selected to have a high transmittance material, so that the external light beam L (for example, the strong light that is irradiated to the backlight) is incident on the electrochromic panel 100 from the transparent cover 110. The light beam L incident on the electrochromic panel 100 can be made to function, such as to reduce specular reflection or anti-glare, via the action of the electrochromic film 130. For example, the material of the transparent cover plate 110 may include glass, but is not limited thereto.
透光蓋板110具有外表面S1以及內表面S2。內表面S2與外表面S1彼此相對，其中內表面S2位於外表面S1與第一黏著層120之間，且電致變色薄膜130透過第一黏著層120貼附於內表面S2上。如圖1所示，外表面S1以及內表面S2可皆為平面，但本發明不限於此。在一實施例中，外表面S1以及內表面S2可分別為平面、曲面或上述兩者的組合。 The light transmissive cover 110 has an outer surface S1 and an inner surface S2. The inner surface S2 and the outer surface S1 are opposed to each other, wherein the inner surface S2 is located between the outer surface S1 and the first adhesive layer 120, and the electrochromic film 130 is attached to the inner surface S2 through the first adhesive layer 120. As shown in FIG. 1, the outer surface S1 and the inner surface S2 may both be flat, but the invention is not limited thereto. In an embodiment, the outer surface S1 and the inner surface S2 may each be a plane, a curved surface, or a combination of the two.
電致變色薄膜130可順應內表面S2的彎曲程度(圖1繪示內表面S2為平面)而貼附於透光蓋板110的內表面S2上。在本實施例中，電致變色薄膜130包括第一導電膜132、第二導電膜134、第二黏著層136以及電致變色層138，其中第二導電膜134透過第二黏著層136貼附於第一導電膜132上，且電致變色層138配置於第一導電膜132以及第二導電膜134的其中一者上且位於第一導電膜132以及第二導電膜134之間。如圖1所示，電致變色層138例如配置於第一導電膜132上且透過第二黏著層136與第二導電膜134接合。此外，第一導電膜132可透過第一黏著層120與透光蓋板110的內表面S2接合。換句話說，電致變色層138位於第二黏著層136與第一導電膜132之間，且第一黏著層120位於第一導電膜132與透光蓋板110之間。 The electrochromic film 130 is attached to the inner surface S2 of the transparent cover 110 in conformity with the degree of bending of the inner surface S2 (the inner surface S2 is shown in FIG. 1). In the present embodiment, the electrochromic film 130 includes a first conductive film 132, a second conductive film 134, a second adhesive layer 136, and an electrochromic layer 138, wherein the second conductive film 134 is attached through the second adhesive layer 136. On the first conductive film 132, the electrochromic layer 138 is disposed on one of the first conductive film 132 and the second conductive film 134 and between the first conductive film 132 and the second conductive film 134. As shown in FIG. 1 , the electrochromic layer 138 is disposed, for example, on the first conductive film 132 and bonded to the second conductive film 134 through the second adhesive layer 136 .

在本實施例中，電致變色層138為固態的電致變色層。舉例而言，固態的電致變色層138的製作方法可以包括將液態的電致變色材料形成於第一導電層132A上，再經由乾燥步驟使液態的電致變色材料固化。如此，則可接續電致變色層138與第二導電膜134的貼合製程。電致變色材料可為無機材料或有機材料。無機材料可包括金屬氧化物或共價鍵金屬錯合物。金屬氧化物例 如是過渡金屬氧化物，如WO3、MoO3、V2O5、Nb2O5、NiO、SnO、Fe2O3、CoO、Ir2O3、Rh2O3或MnO2。共價鍵金屬錯合物例如是普魯士藍(Prussian Blue)。有機材料例如是苯胺單體、二氧乙基噻吩(EDOT)單體或威樂晶(Viologen)單體聚合而成的高分子聚合物。 In this embodiment, electrochromic layer 138 is a solid electrochromic layer.

習知以灌注的方式將液態的電致變色材料形成於兩導電玻璃之間的間隙中，須先藉由封裝材料形成用以容納電致變色材料的間隙，再將間隙抽真空，以灌注液態的電致變色材料。在將間隙抽真空的過程中，導電玻璃容易因內外壓力差而塌陷，使得後續衍生出許多問題(如彩虹紋以及牛頓環等)。本實施例以黏貼的方式將電致變色薄膜130貼附於透光蓋板110的內表面S2上，除了可省略習知形成間隙以及抽真空的步驟之外，還可控制電致變色薄膜130貼附於透光蓋板110上的平整性。如此，有助於改善彩虹紋以及牛頓環等現象，使電致變色面板100具有良好的顯示品質。此外，液態的電致變色材料中具有高腐蝕特性的乳化物，本實施例藉由形成固態的電致變色層138可降低電致變色層138的腐蝕性，從而可降低第一導電層132A以及第二導電層134A對於耐腐蝕性的要求。 Conventionally, a liquid electrochromic material is formed in a gap between two conductive glasses by infusion, and a gap for accommodating the electrochromic material is first formed by the encapsulating material, and then the gap is evacuated to infuse the liquid. Electrochromic material. During the vacuuming of the gap, the conductive glass is liable to collapse due to the pressure difference between the inside and the outside, which causes subsequent problems (such as rainbow stripes and Newton rings). In this embodiment, the electrochromic film 130 is attached to the inner surface S2 of the transparent cover plate 110 in an adhesive manner, and the electrochromic film 130 can be controlled in addition to the steps of forming a gap and vacuuming. The flatness attached to the transparent cover plate 110. In this way, it helps to improve the phenomenon of rainbow lines and Newton's rings, and the electrochromic panel 100 has good display quality. In addition, in the liquid electrochromic material, an emulsion having high corrosion characteristics, in this embodiment, the corrosion of the electrochromic layer 138 can be reduced by forming the solid electrochromic layer 138, thereby reducing the first conductive layer 132A and The second conductive layer 134A has requirements for corrosion resistance.
電致變色面板100可進一步包括控制器140以及感光元件150，其中控制器140電性連接於第一導電膜132以及第二導電膜134，用以調變第一導電膜132與第二導電膜134之間的電壓差。舉例而言，控制器140可為直流電源，其中第一導電膜132以及第二導電膜134的其中一者連接於控制器140的正極，且第 一導電膜132以及第二導電膜134的其中另一者連接於控制器140的負極。 The electrochromic panel 100 may further include a controller 140 and a photosensitive element 150, wherein the controller 140 is electrically connected to the first conductive film 132 and the second conductive film 134 for modulating the first conductive film 132 and the second conductive film The voltage difference between 134. For example, the controller 140 may be a DC power source, wherein one of the first conductive film 132 and the second conductive film 134 is connected to the anode of the controller 140, and the first The other of one of the conductive film 132 and the second conductive film 134 is connected to the negative electrode of the controller 140.
感光元件150電性連接於控制器140。感光元件150適於根據外在環境的光強度輸出感測值，且控制器140根據感測值調變第一導電膜132與第二導電膜134之間的電壓差，使電致變色層138呈現不同的顏色變化，如色彩變化或深淺(灰階)變化等。舉例而言，當感光元件150感測到有強光(如光束L)投射至透光蓋板110時，感光元件150會輸出感測值至控制器140。控制器140依據感測值的大小提供電壓至第一導電層132A以及第二導電層134A，使第一導電層132A以及第二導電層134A之間形成電場。在電場的作用下，電致變色層138會發生電化學的氧化還原反應而得失電子，從而改變其原本的狀態，例如從透明狀態轉換至不透明狀態，使得大部分的光束L被電致變色層138吸收，從而降低電致變色面板100的反射率並達到防眩光的效果。 The photosensitive element 150 is electrically connected to the controller 140. The photosensitive element 150 is adapted to output a sensing value according to the light intensity of the external environment, and the controller 140 modulates the voltage difference between the first conductive film 132 and the second conductive film 134 according to the sensing value, so that the electrochromic layer 138 is caused. Present different color changes, such as color changes or shades (grayscale) changes. For example, when the photosensitive element 150 senses that strong light (such as the light beam L) is projected to the transparent cover plate 110, the photosensitive element 150 outputs a sensed value to the controller 140. The controller 140 provides a voltage to the first conductive layer 132A and the second conductive layer 134A according to the magnitude of the sensed value to form an electric field between the first conductive layer 132A and the second conductive layer 134A. Under the action of the electric field, the electrochromic layer 138 undergoes an electrochemical redox reaction to lose electrons, thereby changing its original state, for example, from a transparent state to an opaque state, so that most of the light beam L is electrochromic layer. 138 absorbs, thereby reducing the reflectivity of the electrochromic panel 100 and achieving an anti-glare effect.
