Abstract
Description
本發明是有關於一種紅色染料化合物及紅色染料組成物,且特別是有關於一種用於電濕潤顯示裝置之紅色染料化合物及紅色染料組成物。 The present invention relates to a red dye compound and a red dye composition, and more particularly to a red dye compound and a red dye composition for use in an electrowetting display device.
近年來,電子紙(E-paper)與電子書(E-book)正蓬勃發展,具有更輕薄與可撓曲特性的顯示器將成為未來主要發展的趨勢。電濕潤顯示器(Electrowetting Display Device,EWD)則是一種可應用在電子書以及電子紙的顯示面板。 In recent years, electronic paper (E-paper) and e-book (E-book) are booming, and displays with thinner and more flexible characteristics will become the main development trend in the future. Electrowetting Display Device (EWD) is a display panel that can be applied to e-books and electronic paper.
一般而言,電濕潤顯示器包括上電極、下電極以及夾於兩電極之間的極性流體以及非極性流體。電濕潤顯示器的操作方法是,當未施加電壓時,油墨層(非極性流體)佈滿畫素單元。如此可使入射光被反射層反射而呈現亮態。另外,當欲使畫素單元呈現亮態時,則對其上下兩電極施加電壓,以使油墨層收縮在所述畫素區域的邊緣,進而露出位於油墨層下方的反射層。如此可使 入射光被反射層反射而呈現亮態。 In general, an electrowetting display includes an upper electrode, a lower electrode, and a polar fluid sandwiched between the electrodes and a non-polar fluid. The electrowetting display is operated by the ink layer (non-polar fluid) being filled with the pixel unit when no voltage is applied. This allows the incident light to be reflected by the reflective layer to assume a bright state. In addition, when the pixel unit is to be in a bright state, a voltage is applied to the upper and lower electrodes to shrink the ink layer at the edge of the pixel region, thereby exposing the reflective layer under the ink layer. So that The incident light is reflected by the reflective layer to present a bright state.
另一方面,若欲使電濕潤顯示器顯示彩色影像,一般會在電濕潤顯示器的油墨層中混入彩色染料。當未施加電壓於上下電極時,混有彩色染料的油墨層佈滿畫素單元,可使入射光穿透過混有彩色染料的油墨層而使所述畫素單元呈現彩色影像。反之,當欲使畫素單元呈現暗態時,則對其上下兩電極施加電壓,以使油墨層收縮到所述畫素區域的邊緣。然而,傳統彩色染料的耐日光牢度(light fastness)不佳,且必需經過繁複的純化過程才可使用,使得彩色電濕潤顯示器之發展仍有許多可改善之處。 On the other hand, if the electrowetting display is to display a color image, a color dye is generally mixed in the ink layer of the electrowetting display. When no voltage is applied to the upper and lower electrodes, the ink layer mixed with the color dye is covered with the pixel unit, and the incident light is allowed to penetrate the ink layer mixed with the color dye to cause the pixel unit to present a color image. On the other hand, when the pixel unit is to be in a dark state, a voltage is applied to the upper and lower electrodes to shrink the ink layer to the edge of the pixel region. However, conventional color dyes have poor light fastness and must be subjected to complicated purification processes, so that there are still many improvements in the development of color electrowetting displays.
