Description
本發明是有關於一種顯示裝置，且特別是有關於一種彩色電泳顯示裝置(electrophoretic display apparatus)。 The present invention relates to a display device, and more particularly to an electrophoretic display apparatus.
電子紙(e-paper)以及電子書(e-book)係採用電泳顯示技術來達到顯示的目的。以顯示黑白的電子書為例，其顯示介質主要是由黑色電泳液以及摻於黑色電泳液中的白色帶電粒子所構成，透過施加電壓的方式可以驅動白色帶電粒子移動，以使各個畫素分別顯示黑色、白色或灰階。 Electronic paper (e-paper) and e-book (e-book) use electrophoretic display technology to achieve the purpose of display. Taking an electronic book showing black and white as an example, the display medium is mainly composed of a black electrophoresis liquid and white charged particles doped in a black electrophoresis liquid, and the white charged particles can be driven by applying a voltage so that the respective pixels are respectively separated. Display black, white or grayscale.
在現有技術中，電泳顯示器多半是利用外界光源的反射來達成顯示的目的，而透過電壓驅動摻於電泳液中的白色帶電粒子可以使各個畫素顯示出所需的灰階。再者，為了擴大電泳顯示器的應用，亦可於電泳顯示薄膜上設置彩色濾光薄膜。此時，電泳顯示器的色彩的呈現主要是利用外界光通過彩色濾光薄膜後，電泳液中的白色帶電粒子會將外界光反射後再穿透彩色濾光薄膜而進行顯示。 In the prior art, the electrophoretic display mostly uses the reflection of the external light source to achieve the purpose of display, and the white charged particles doped in the electrophoresis liquid by the voltage driving can cause the respective pixels to display the desired gray scale. Furthermore, in order to expand the application of the electrophoretic display, a color filter film may be disposed on the electrophoretic display film. At this time, the color of the electrophoretic display is mainly represented by the external light passing through the color filter film, and the white charged particles in the electrophoresis liquid reflect the external light and then penetrate the color filter film for display.
一般來說，彩色濾光層主要是由多個不同顏色的濾光圖 案所組成，且每一個不同顏色的濾光圖案會分別對應驅動陣列基板上一個畫素單元。電泳顯示器利用白色帶電粒子與黑色帶電粒子進行吸收與反射光線，再搭配紅色、綠色、藍色的濾光圖案來呈現彩色的顯示畫面。惟現有技術中，特定顏色的表現無法達到預期，因此需要此特定顏色混色來產生的色彩也連帶表現不佳。 In general, the color filter layer is mainly composed of multiple filters of different colors. The composition of the case, and each filter pattern of different colors corresponds to a pixel unit on the driving array substrate. The electrophoretic display uses white charged particles and black charged particles to absorb and reflect light, and then combines red, green, and blue filter patterns to display a color display. However, in the prior art, the performance of a specific color cannot be expected, and thus the color required to be mixed by the specific color is also poorly performed.

In this embodiment, the color filter patterns are not correspondingly arranged on the display media 132_1 and 132_2.
在圖2的實施例中，驅動電晶體114例如驅動顯示單元116顯示白色。在顯示介質132_1(第一顯示介質)中，相較於白色帶電粒子W以及黑色帶電粒子K，彩色帶電粒子C最靠近彩色濾光層120。在顯示介質132_2(第二顯示介質)中，相較於彩色帶電粒子C以及黑色帶電粒子K，白色帶電粒子W最靠近彩色濾光層120。在顯示介質132_3(第三顯示介質)中，相較於彩色帶電粒子C以及黑色帶電粒子K，白色帶電粒子W最靠近彩色濾光層120。在顯示介質132_4(第四顯示介質)中，相較於彩色帶電粒子C以及黑色帶電粒子K，白色帶電粒子W最靠近彩色濾光層120。因此，在顯示單元116當中的畫素單元112由左而右依序顯示綠色、藍色、紅色及白色，從而顯示單元116之整體顯示白色。 In the embodiment of FIG. 2, the drive transistor 114, for example, drives the display unit 116 to display white. In the display medium 132_1 (first display medium), the colored charged particles C are closest to the color filter layer 120 as compared with the white charged particles W and the black charged particles K. In the display medium 132_2 (second display medium), the white charged particles W are closest to the color filter layer 120 as compared with the colored charged particles C and the black charged particles K. In the display medium 132_3 (third display medium), the white charged particles W are closest to the color filter layer 120 as compared with the colored charged particles C and the black charged particles K. In the display medium 132_4 (fourth display medium), the white charged particles W are closest to the color filter layer 120 as compared with the colored charged particles C and the black charged particles K. Therefore, the pixel units 112 among the display units 116 sequentially display green, blue, red, and white from left to right, so that the entirety of the display unit 116 displays white.
