Description
本發明係有關於一種控制電路與方法，尤其是指一種用以維持電致變色元件之透光度的控制電路與方法。The present invention relates to a control circuit and method, and more particularly to a control circuit and method for maintaining the transmittance of an electrochromic element.
當給予物質一個外加電位，而該物質呈現可逆性顏色變化時，該物質稱為電致變色材料（ｅｌｅｃｔｒｏｃｈｒｏｍｉｃ ｍａｔｅｒｉａｌｓ）。即，電致變色材料藉由外加電場所引起的顏色變化現象，而產生氧化還原狀態之可逆變化以呈現不同之吸收光譜變化；因此，電致變色也可以稱為電變色，且電致變色材料因氧化還原的狀態不同，呈現顏色的差異。於是，由電致變色所組成的元件，可以藉由操作電壓調控其顏色或穿透度變化，亦即只要以極小的電壓驅動後，便能使電致變色元件進行著色動作，當停止外加電位時，離子將緩慢地以擴散方式離開變色層而去色，因此藉由對兩極反覆切換正負電壓，使電致變色元件內部發生電化學反應，產生著色（ｃｏｌｏｕｒｅｄ）及去色（ｂｌｅａｃｈｅｄ）之視覺色彩上的改變。而電致變色元件之著色及去色效率決定於離子在變色層中移動的速率。When an applied potential is applied to a substance that exhibits a reversible color change, the substance is referred to as electrochromic materials. That is, the electrochromic material produces a reversible change in the redox state to exhibit different absorption spectrum changes by a color change phenomenon caused by an externally applied electric field; therefore, electrochromism may also be referred to as electrochromic, and the electrochromic material may be The difference in color is exhibited due to the state of redox. Therefore, the element composed of electrochromic can be controlled by the operating voltage to change its color or transmittance, that is, the electrochromic element can be colored after being driven with a very small voltage, and the external potential is stopped. When the ions are slowly diffused away from the color changing layer to remove the color, the electrochemical reaction occurs inside the electrochromic element by switching the positive and negative voltages on the two electrodes to produce a colored and bleached vision. The change in color. The coloring and color removal efficiency of the electrochromic element is determined by the rate at which ions move in the color changing layer.
由於電致變色材料能經由外加電位的控制，產生穿透率的變化，並具有可逆性與記憶效應，同時可調節與控制不同波長電磁輻射之入射輛，達到濾光、明暗及節能控制之目的，因此近年來逐漸受到重視。常見的電致變色材料可區分為以下四大類：Since the electrochromic material can control the change of the transmittance through the application of the applied potential, and has reversibility and memory effect, and can adjust and control the incident beam of electromagnetic radiation of different wavelengths, to achieve the purpose of filtering, shading and energy saving control. Therefore, it has gradually received attention in recent years. Common electrochromic materials can be divided into the following four categories:
（１）過渡金屬氧化物（ｔｒａｎｓｉｔｉｏｎ ｍｅｔａｌ ｏｘｉｄｅｓ）：節能窗戶中常用的三氧化鎢（ｔｕｎｇｓｔｅｎ ｏｘｉｄｅ）為典型的代表，其氧化狀態為無色、還原態則呈現藍色；(1) Transition metal oxides: Tungsten oxide commonly used in energy-saving windows is a typical representative, and its oxidation state is colorless, and the reduced state is blue;
（２）金屬氰化鐵錯合物（ｍｅｔａｌｈｅｘａｃｙａｎｏｆｅｒｒａｔｅｓ）：由金屬離子和赤血鹽（ｆｅｒｒｉｃ ｃｙａｎｉｄｅ）沈積而得，電化學可逆性極佳，如普魯士藍（ｐｒｕｓｓｉａｎ ｂｌｕｅ），還原態下無色透明，但氧化後可顯現藍色或綠色；(2) Metallic hexacyanoferrates: deposited by metal ions and ferric cyanide, with excellent electrochemical reversibility, such as prussian blue, colorless and transparent in the reduced state. But after oxidation, it can appear blue or green;
（３）雜環導電高分子（ｈｅｔｅｒｏｃｙｃｌｉｃｃｏｎｄｕｃｔｉｎｇ ｐｏｌｙｍｅｒｓ ）：種類繁多，色彩豐富，例如聚苯胺（ｐｏｌｙａｎｉｌｉｎｅ），可隨著氧化電位的施加依序呈現淺黃色、綠色、藍色及紫色的變化；(3) Heterocyclic conducting polymers: a wide variety of colors, such as polyaniline, which can be changed in light yellow, green, blue and purple with the application of oxidation potential;
（４）機聯啶分子（ｏｒｇａｎｉｃ ｂｉｐｙｒｉｄｉｌｉｕｍｓ）：例如與農藥巴拉刈（ｐａｒａｑｕａｔ）結構相似的紫精分子（ｈｅｐｔｙｌ ｖｉｏｌｏｇｅｎ）已廣泛地被用在高級房車的變色後視鏡中，其氧化態為無色、還原態呈現紫色。(4) Organic bipyridiliums: For example, a heptriet molecule (heptyl viologen) similar in structure to the paraquat has been widely used in the color-changing rearview mirror of a premium motorhome, and its oxidation state is The colorless, reduced state appears purple.
然而，當對電致變色材料施加電壓之時間越長，其顏色深度越深，而透光度也會越來越低，因此，並不適合使用於須具有良好透光度如交通工具之特殊玻璃上。However, the longer the voltage is applied to the electrochromic material, the deeper the color depth and the lower the transmittance, and therefore it is not suitable for use in special glass which has good transparency such as transportation. on.
