Description

反射式電子顯示裝置 Reflective electronic display device

本發明一種反射式電子顯示裝置，有關於可顯示多灰階的反射式電子裝置。 The invention relates to a reflective electronic display device, which relates to a reflective electronic device capable of displaying multiple gray levels.

近年來顯示科技上具有飛躍式的進步，電子顯示裝置已被廣泛研究及應用，且可作為低電力消耗之顯示裝置之一，例如：電子紙、電子閱讀器等已經吸引大眾的注意，此類顯示器的最大優點為顯示資訊時不需耗費電力，只有在切換顯示資訊時才需耗費電力，且此電子紙、電子閱讀器所需的光源以環境光為主，並沒有內建背光源，可免除背光源所造成之主要能源消耗，故可大幅延長電池使用時間。上述的電子商品在色彩的顯示上可採用所謂的「膽固醇液晶顯示器」(英語：cholesteric liquid crystal display，縮寫「ChLCD」)(Reflective liquid crystal display,S.-T.Wu,D.-K.Yang,Wiley 2001)作為電子閱讀器，其優點為顯示彩色資訊時不需持續耗費電力，且此閱讀器的光源以外在環境光源為主，可大幅減省電池電力消耗。但其缺點為膽固醇液晶螺距結構(如螺距長度)的排列方式會隨著溫度而變化，因此反射光波長隨溫度改變，使顯示器所顯示的顏色、色彩會隨溫度變化；另膽固醇液晶主要必須透過電壓才得以驅動，相對於一般常見的液晶顯示器，其所需的電壓較高、且反應速度較慢，此部分敘述可參考下列書籍「Reflective liquid crystal display,S.-T.Wu,D.-K.Yang,Wiley 2001」；其他的電子閱讀器顯示技術，如電泳式顯示器，可參考「Recent Pat.Nanotechnol. 2010；4(3)：137-49」，以及採用光學干涉原理的電子閱讀器，如美國專利「INTERFEROMETRIC MODULATOR,US 7,847,999 B2,2010」等，也被廣泛的研究和開發。 In recent years, display technology has made rapid progress. Electronic display devices have been widely studied and applied, and can be used as one of the display devices with low power consumption. For example, electronic paper, e-readers, etc. have attracted public attention. The biggest advantage of the display is that it does not consume electricity when displaying information. It only consumes electricity when switching to display information. The light source required by this e-paper and e-reader is mainly ambient light, and there is no built-in backlight. Eliminate the main energy consumption caused by the backlight, so it can greatly extend the battery life. The above-mentioned electronic products can use the so-called "cholesteric liquid crystal display" (English: cholesterol liquid crystal display, abbreviation "ChLCD") (Reflective liquid crystal display, S.-T.Wu, D.-K.Yang) for color display. Wiley 2001) as an e-reader, its advantage is that it does not need to continuously consume power when displaying color information, and the light source of this reader is mainly external ambient light sources, which can greatly reduce battery power consumption. But its disadvantage is that the arrangement of the cholesteric liquid crystal pitch structure (such as the pitch length) will change with temperature, so the reflected light wavelength changes with temperature, so that the color and color displayed on the display will change with temperature; in addition, cholesteric liquid crystal must mainly pass through The voltage can be driven. Compared with the common liquid crystal display, the required voltage is higher and the response speed is slower. For this part of the description, please refer to the following book "Reflective liquid crystal display, S.-T.Wu,D.- K. Yang, Wiley 2001"; for other e-reader display technologies, such as electrophoretic displays, please refer to "Recent Pat. Nanotechnol. 2010;4(3):137-49", and electronic readers using the principle of optical interference, such as the US patent "INTERFEROMETRIC MODULATOR, US 7,847,999 B2, 2010", etc., have also been extensively researched and developed.

目前市面上最常見的電子閱讀器所使用的技術為電子墨水(E-INK)技術，其原理可參考美國專利「E-INK DISPLAY PANEL,US 2008/0043317 A1,2008」，在進行顯示畫面更新時，畫面容易產生短暫的黑屏或影像殘留等問題，而台灣專利號I605292「電場驅動顯示裝置」也提出了降低像素影像殘留的方法。綜合以上，相關業者對於上述所具有的問題必須思考該如何解決，才能夠呈現出更佳的畫面，並讓使用者有更好的閱讀體驗。 The most common e-reader on the market currently uses electronic ink (E-INK) technology. For its principle, please refer to the US patent "E-INK DISPLAY PANEL, US 2008/0043317 A1, 2008". The display screen is updated. At times, the screen is prone to short-term black screen or image sticking. Taiwan Patent No. I605292 "Electric Field Driven Display Device" also proposes a method to reduce pixel image sticking. Based on the above, the relevant industry must think about how to solve the above-mentioned problems in order to present a better picture and allow users to have a better reading experience.

After the light passes through the first polarizer, it is reflected by the reflector and passes through the first polarizer again. , And towards the second polarization The film transmission is defined as the bright state mode; and the electromagnetic micro-electromechanical assembly drives the main substrate, drives the reflector to rotate the first polarizer, and makes the first penetration axis relative to the second penetration axis When they are perpendicular to each other, the light cannot reach the reflector after being transmitted by the second polarizer because the light absorbed by the first polarizer is defined as a dark state mode; and the electromagnetic micro-electromechanical group drives the main substrate to drive the reflector, and then move The first polarizer rotates to form an included angle between the first transmission axis and the second transmission axis. By controlling the size of the included angle, the display of gray scale can be controlled, which is defined as a gray scale mode.

為了清楚說明本發明所能達成上述之目的及功效，茲搭配圖示就本發明的實施例加以更詳細說明其特徵與功效，以下說明不考慮在不同介面處所產生的反射。請參閱第一圖至第八圖所示，本發明為一種反射式電子顯示裝置，係為畫素或子畫素，其包括：一主基板1；一電磁微機電組2，其裝設於該主基板1的一側，另設有一軸桿(圖未示)連接於該電磁微機電組2及該主基板1；一反射件3，其疊設於該主基板1的另一側，又該電磁微機電組2係透過該軸桿帶動主基板1，進而帶動連接於其上的反射件3進行水平方向的旋轉；一第一偏振片4，其疊設於該反射件3並相反於該主基板1之反射面，而該第一偏振片4 進一步定義一第一穿透軸41；及一第二偏振片5，其設置於入光測並且與第一偏振片4間呈間距設置，而該第二偏振片5進一步定義一第二穿透軸51；又該電磁微機電組2驅動該主基板1而帶動反射件3，進而連動該第一偏振片4旋轉，且使該第一穿透軸41相對該第二穿透軸51相互為平行時，光線由該第二偏振片5透射並朝向該第一偏振片4照射，光線完全通過第一偏振片4後，光線經由該反射件3被反射後，由於偏振方向不變，故光線可再次通過第一偏振片，並朝向該第二偏振片5透出係定義為亮態模式，上述第一偏振片4和第二偏振片5之間的間距設置是為了使第一偏振片4在旋轉時不會和第二偏振片5產生摩擦；而該電磁微機電組2驅動該主基板1而帶動該反射件3，其進而連動該第一偏振片4旋轉，且使該第一穿透軸41相對該第二穿透軸51呈相互垂直時，光線由該第二偏振片5透射後無法抵達反射件3因光線受該第一偏振片4吸收係定義為暗態模式；又該電磁微機電組2驅動該主基板1而帶動反射件3，進而連動該第一偏振片4旋轉，且使該第一穿透軸41與該第二穿透軸51之間形成一夾角6，控制夾角6的大小即可調整灰階即定義為灰階模式，本案的顯示裝置在切換畫面顯示時，並不會產生黑屏或是影像殘留等問題，並於顯示畫面時，不需持續耗費電力。 In order to clearly illustrate that the present invention can achieve the above-mentioned objects and effects, the features and effects of the embodiments of the present invention are described in more detail in conjunction with the figures. The following description does not consider reflections generated at different interfaces. Please refer to Figures 1 to 8. As shown in Figures 1 to 8, the present invention is a reflective electronic display device, which is a pixel or sub-pixel, and includes: a main substrate 1; an electromagnetic microelectromechanical assembly 2 mounted on One side of the main substrate 1 is additionally provided with a shaft (not shown) connected to the electromagnetic micro-electromechanical assembly 2 and the main substrate 1; a reflector 3 which is stacked on the other side of the main substrate 1, In addition, the electromagnetic micro-electromechanical assembly 2 drives the main substrate 1 through the shaft, and then drives the reflector 3 connected to it to rotate in the horizontal direction; a first polarizer 4 is stacked on the reflector 3 and opposite On the reflective surface of the main substrate 1, and the first polarizer 4 Further define a first transmission axis 41; and a second polarizer 5, which is arranged on the incident light and is spaced apart from the first polarizer 4, and the second polarizer 5 further defines a second transmission Axis 51; and the electromagnetic micro-electromechanical group 2 drives the main substrate 1 to drive the reflector 3, and then rotate the first polarizer 4, and make the first penetration axis 41 relative to the second penetration axis 51 mutually When parallel, the light is transmitted by the second polarizer 5 and irradiated toward the first polarizer 4. After the light passes through the first polarizer 4, the light is reflected by the reflector 3, and the polarization direction remains unchanged. It can pass through the first polarizer again and pass through the second polarizer 5 as the bright state mode. The above-mentioned spacing between the first polarizer 4 and the second polarizer 5 is to make the first polarizer 4 When rotating, there is no friction with the second polarizer 5; and the electromagnetic micro-electromechanical assembly 2 drives the main substrate 1 to drive the reflector 3, which in turn drives the first polarizer 4 to rotate and causes the first wear When the transmission axis 41 is perpendicular to the second transmission axis 51, the light cannot reach the reflector 3 after being transmitted by the second polarizer 5 because the light is absorbed by the first polarizer 4, which is defined as a dark state mode; The electromagnetic micro-electromechanical assembly 2 drives the main substrate 1 to drive the reflector 3, which in turn rotates the first polarizer 4, and forms an angle 6 between the first penetration axis 41 and the second penetration axis 51, The gray scale can be adjusted by controlling the size of the angle 6, which is defined as the gray scale mode. The display device in this case will not produce black screen or image retention when switching the screen display, and it does not need to continue to consume power when displaying the screen. .

根據上述說明，本發明主要可以分成亮態模式、暗態模式及灰階模式三部分進行討論及說明，首先請參閱第一至三圖所示，當要切換為亮態模式時，透過該電磁微機電組2的運作，使得該反射件3、該第一偏振片4受到控制而旋轉，最後使該第一偏振片4的該第一穿透軸41與該第二偏振片5的第二穿透軸51呈相互平行，故光線(所指為無偏振光)垂直由該第二偏振片5的一側射入，光線射入的強度為T，當光線通過該第二偏振片5時會有百分之五十的光線會被吸收，其光線強度僅會剩下T/2，剩下的光線繼續射入第一穿透軸41與第二穿透軸 51呈相互平行的第一偏振片4後其可穿過第一偏振片4，當光線到達底部的反射件3後予以反射，其光線的偏振方向不變，使得光線經由反射件3後可再次通過第一偏振片4，朝第二偏振片5透射而出，此時的光線強度依然可以維持在初始經過第二偏振片5的強度亦即T/2，如此即可具有一定的亮度進行顯示，由於使用外在環境光源，故不會耗費過多的電力；接著再請參閱第四、五圖所示，切換為暗態模式時，當光線(所指為無偏振光)垂直的由第二偏振片5的一側射入，光線射入的強度為T，當光線通過該第二偏振片5的時候會有百分之五十的光線受到吸收，其光線強度僅會剩下T/2，剩下的光線會繼續朝向第一偏振片4射入，而此時該電磁微機電組2的運作驅動該主基板1而帶動反射件3及第一偏振片4進行旋轉，使得該第一穿透軸41與該第二穿透軸51呈相互垂直，因此由第二偏振片5射入後朝向第一偏振片4的光線，經由第一偏振片4後則全數受到吸收，不會有任何的光線被設置位於第一偏振片4一側的反射件3予以反射，使得無光線再射出該第二偏振片5而使光線強度為0，如此一來讓畫面不具有亮度；最後一種模式請參閱第六、七、八圖所示，本發明除了亮態及暗態之間的切換外，更具有另一種模式，也就是灰階模式，當該電磁微機電組2驅動該主基板1的運作將反射件3及第二偏振片5進行帶動旋轉，讓該第一穿透軸41與該第二穿透軸51之間形成有夾角6狀態(夾角6的形成係將第一軸線41投影至第二偏振片5上，使得第一穿透軸41與第二穿透軸51之間形成有夾角6的角度位置)，假若當光線(所指為無偏振光)垂直的由第二偏振片5的一側射入，且入射光的強度為T，經過第二偏振片5後會有百分之五十的光線會被該第二偏振片5吸收，使得光線強度僅剩下T/2，假設第一穿透軸41與第二穿透軸51之間的夾角為θ，因此由於馬呂斯定律(Malus' law)可知，通過第一偏振片4的光線強度剩下Tcos2θ/2，此定律可參考書籍「E. Hecht,Optics(Addison Wesley,2002)」；又光線經過第一偏振片4後朝向反射件3行進，經由反射件3的反射後，光線再次往第一偏振片4行進，因光線經過反射後其偏振方向不變，因此光線可以完全的通過第一偏振片4，且光線強度不會有任何的改變，光線透射出第一偏振片4後往第二偏振片5繼續行進，因第一穿透軸41與第二穿透軸51之間是具有夾角6(θ)，再透過馬呂斯定律(Malus' law)可知，穿透第二偏振片5的光線強度為Tcos4θ/2，由此可知利用該電磁微機電組2進行反射件3、第一偏振片4的旋轉控制下，在不同的夾角6角度下可以有效的控制灰階的變化，第八圖可為夾角6對反射率的作圖，水平軸為角度(此角度係為夾角6(θ))、垂直軸為光線的反射率，從關係圖可知當第一穿透軸41與第二穿透軸51之間的夾角為0度時，其光線強度可以為0.5，而當第一穿透軸41與第二穿透軸51之間的夾角逐漸變大，其反射率逐漸降至0，由關係圖可知，角度越小其反射率越高，角度越大其反射率越小，由此利用角度上的變化調整進而可達到更多灰階的顯示呈現。 According to the above description, the present invention can be divided into three parts: bright mode, dark mode, and gray-scale mode for discussion and description. First, please refer to the first to third figures. When switching to the bright mode, through the electromagnetic The operation of the MEMS 2 makes the reflector 3 and the first polarizer 4 be controlled to rotate, and finally the first transmission axis 41 of the first polarizer 4 and the second polarizer 5 of the second The transmission axes 51 are parallel to each other, so the light (referred to as unpolarized light) perpendicularly enters from one side of the second polarizer 5, and the intensity of the light incident is T. When the light passes through the second polarizer 5 Fifty percent of the light will be absorbed, and the light intensity will only remain T/2, and the remaining light will continue to enter the first penetration axis 41 and the second penetration axis 51 parallel to each other. After the polarizer 4, it can pass through the first polarizer 4. When the light reaches the reflector 3 at the bottom, it is reflected, and the polarization direction of the light remains unchanged, so that the light can pass through the first polarizer 4 again after passing through the reflector 3. It is transmitted toward the second polarizer 5, and the intensity of the light at this time can still be maintained at the original intensity that passed through the second polarizer 5, that is, T/2, so that it can display with a certain brightness, due to the use of external environmental light sources , So it will not consume too much power; then please refer to the fourth and fifth figures. When switching to the dark mode, when the light (referred to as unpolarized light) is perpendicular to the side of the second polarizer 5 When the light passes through the second polarizer 5, 50% of the light will be absorbed, and the light intensity will only remain T/2, and the remaining light will continue It is incident toward the first polarizer 4, and at this time, the operation of the electromagnetic micro-electromechanical assembly 2 drives the main substrate 1 to drive the reflector 3 and the first polarizer 4 to rotate, so that the first penetration axis 41 and the second The two transmission axes 51 are perpendicular to each other. Therefore, the light that enters the first polarizer 4 from the second polarizer 5 is completely absorbed after passing through the first polarizer 4, and no light is set at the first polarizer 4. The reflector 3 on one side of the polarizer 4 reflects, so that no light is emitted from the second polarizer 5 and the light intensity is 0, so that the picture does not have brightness; for the last mode, please refer to the sixth, seventh, As shown in Figure 8, in addition to the switch between the bright state and the dark state, the present invention has another mode, which is a gray-scale mode. When the electromagnetic micro-electromechanical assembly 2 drives the operation of the main substrate 1, the reflector 3 and The second polarizer 5 is driven to rotate, so that an included angle 6 is formed between the first transmission axis 41 and the second transmission axis 51 (the formation of the included angle 6 is to project the first axis 41 to the second polarizer 5 Above, so that the first penetration axis 41 and the second penetration axis 51 form an angle of 6), if the light (referred to as unpolarized light) is perpendicular to the side of the second polarizer 5 And the intensity of the incident light is T. After passing through the second polarizer 5, 50% of the light will be absorbed by the second polarizer 5, so that the light intensity is only T/2. The angle between the through axis 41 and the second through axis 51 is θ , so due to Marius' law (M alus' law), the light intensity passing through the first polarizer 4 is left with Tcos 2 θ/2. For this law, please refer to the book "E. Hecht, Optics (Addison Wesley, 2002)"; and the light passes through the first polarizer 4 The light travels toward the reflector 3, and after being reflected by the reflector 3, the light travels to the first polarizer 4 again. Because the polarization direction of the light does not change after reflection, the light can completely pass through the first polarizer 4, and the light The intensity will not change at all. The light passes through the first polarizer 4 and then continues to travel to the second polarizer 5. Because the first transmission axis 41 and the second transmission axis 51 have an angle of 6 ( θ ), Through Malus' law, it can be seen that the intensity of the light passing through the second polarizer 5 is Tcos 4 θ/2, and it can be seen that the electromagnetic micro-electromechanical assembly 2 is used for the reflector 3 and the first polarizer 4 Under the rotation control of, the change of gray scale can be effectively controlled under different angles of 6 angles. The eighth figure can be a graph of angle 6 versus reflectivity. The horizontal axis is angle (this angle is angle 6( θ )) , The vertical axis is the reflectivity of light. From the relationship diagram, it can be seen that when the angle between the first penetration axis 41 and the second penetration axis 51 is 0 degrees, the light intensity can be 0.5, and when the first penetration axis The angle between 41 and the second penetration axis 51 gradually increases, and its reflectivity gradually drops to 0. From the relationship diagram, it can be seen that the smaller the angle, the higher the reflectivity, and the larger the angle, the lower the reflectivity. The adjustment of the angle change can achieve more grayscale display.

知曉本發明主要的技術內容下，進一步說明本發明的其餘技術特徵，首先本發明在電磁微機電組2的設置上包含有一驅動電晶體21及一微馬達22，該驅動電晶體21係與該微馬達22電性連結，該驅動電晶體21係控制該微馬達22運作時的正轉、逆轉作動，而該微馬達22透過與軸桿(圖未示)的連結帶動主基板1，進而帶動該反射件3進行旋轉，而進一步調整第一穿透軸41與第二穿透軸51之間的夾角6，進而於亮態模式、暗態模式及灰階模式之間進行切換，請參閱第一圖所示。 Knowing the main technical content of the present invention, the remaining technical features of the present invention will be further explained. First of all, the present invention includes a driving transistor 21 and a micro-motor 22 in the arrangement of the electromagnetic micro-electromechanical unit 2. The driving transistor 21 is connected to the The micromotor 22 is electrically connected. The driving transistor 21 controls the forward and reverse rotation of the micromotor 22 during operation. The micromotor 22 drives the main substrate 1 through the connection with the shaft (not shown), and then drives it The reflector 3 rotates to further adjust the angle 6 between the first penetration axis 41 and the second penetration axis 51, and then switch between the bright mode, the dark mode and the gray scale mode. Please refer to Shown in a picture.

另外，本發明為了呈現出更多灰階的顯示，因此所有的偏振片(第一偏振片4及第二偏振片5)均採用了可以吸收光線波長範圍為可見光的線性偏振 片，可見光的波長範圍從380至780奈米為主；反射件3的設置上也同是採用了可以反射所有可見光的反射件3。 In addition, in order to present more grayscale displays in the present invention, all polarizers (first polarizer 4 and second polarizer 5) adopt linear polarization that can absorb light in the wavelength range of visible light. The wavelength range of visible light is mainly from 380 to 780 nanometers; the reflector 3 is also equipped with a reflector 3 that can reflect all visible light.

最後，本發明為了要保護第二偏振片5不受到外界的影響，因此該第二偏振片5的頂面進一步鋪設一保護件7，並於該保護件7頂面進一步鍍設一抗反射膜8，藉由此設置也能夠減低不同介面造成的反射，進而增加入射光的強度，另外本發明前述說明可以應用於電子紙、電子書、摺疊手機的螢幕上，因此請參閱第十、十一圖所示，以電子紙為例，假若電子紙的紙張大小為A4，那本發明就屬於A4大小內所顯示畫面中的一圓形畫素/圓形子畫素，故可利用複數個本發明的圓形畫素/圓形子畫素相互排列形成電子紙大小的畫面，此排列可參閱論文(APSIPA Trans.Signal Inf.Process.1,1-10(2012)；DOI：10.1017/ATSIP.2012.3)，每一圓形畫素/圓形子畫素都具有獨立的微馬達22，並受每一個獨立的驅動電晶體21所控制，各個獨立的驅動電晶體21全部由一台主電腦控制，所以說當電子紙為黑白顯示時，如第十圖所示，每一個圓形畫素，透過主電腦即可透過對每一個微馬達22的控制調整各個圓形畫素的主基板1、反射件3和第一偏振片4的旋轉，使得每一個圓形畫素可反射特定的亮度，讓整張電子紙可以呈現出各種畫面的顯示。除此之外當電子紙為彩色顯示時，之前黑白顯示時的每一個圓形畫素被視為一個圓形子畫素，可於每一個獨立的圓形子畫素上方(第二偏振片5上)貼上具有顏色(紅色(R)、綠色(G)或藍色(B))的濾光片(如第十一圖所示)，此時每三個圓形子畫素為一畫素，此三個圓形子畫素分別為貼上紅色、綠色和藍色濾光片的圓形子畫素，此時的排列為RGB delta排列，可參閱論文(APSIPA Trans.Signal Inf.Process.1,1-10(2012)；DOI：10.1017/ATSIP.2012.3)，如果每一個圓形子畫素可以顯示16灰階，那麼在彩色顯示的形態下即可顯示4096種顏 色。由於本發明利用旋轉第一偏振片4的方式來顯示亮態、暗態和灰階態，所以主基板1的合適形狀為圓形，反射件3和第一偏振片4的形狀也和主基板1一樣，都為圓形，且主基板1、第一偏振片4和反射件3的直徑都一樣，三者的圓心對齊。總結說明，利用該驅動電晶體21控制微馬達22進行正轉、逆轉的操作，進而分別控制各個獨立圓形畫素/圓形子畫素的主基板1、反射件3及第一偏振片4進行旋轉，藉以改變、調整第一穿透軸41與第二穿透軸51之間的角度，提供在亮態模式、暗態模式及灰階模式三種之間進行切換。利用圖十或圖十一畫素/子畫素排列顯示某一特定畫面，當要切換到下一畫面時，各個圓形畫素/圓形子畫素裡的電磁微機電組2裡的微馬達22，可參考論文「Electromagnetic Micromotors-Design,Fabrication and Applications,Micromachines 2014；5：929-942」，可直接旋轉各個圓形畫素/圓形子畫素裡的第一偏振片4的第一穿透軸41到特定的角度，故可改善習知技術中所述，當電子閱讀器採用E-INK技術，在切換畫面上會有黑屏或是影像殘留的問題，可為使用者帶來更佳的閱讀體驗；本案反射式電子顯示裝置的顯示方式不易受溫度影響；畫面更新的速度取決於電磁微機電組2裡微馬達22的旋轉速度；另外，第一偏振片4和反射件3兩者可以使用單一的一片線柵反射式偏振片所取代，此線柵反射式偏振片(wire grid reflective polarizer)可參考兩篇美國專利「Dual Mode Reflective/Transmissive Liquid Crystal Display Apparatus.U.S.Patent 5 986 730,Nov.16,1999」和「Broadband Wire Grid Polarizer for the Visible Spectrum,”U.S.Patent 6 122 103,Sept.19,2000」；本案的灰階由第一穿透軸41和第二穿透軸51之間的夾角決定(參考第八圖所示)，理論上可以連續顯示灰階；上述以圓形主基板1為例說明，實際也可使用正方形或六角形主基板1，圖十二為將正方形主基板1視為一畫素的排列；圖十三為將六角形主基板1視為一畫素的排列，六角 形和正方形畫素可參閱論文(Comparison of square-pixel and hexagonal-pixel resolution in image processing；DOI：10.1109/CCECE.2002.1013056)。將圖十二和圖十三的畫素視為一子畫素，依照圖十一的順序分別貼上具有紅色(R)、綠色(G)或藍色(B)的濾光片，此時每三個子畫素為一畫素，如果每一個正方形或六角形子畫素可以顯示16灰階，那麼在彩色顯示的形態下一樣可顯示4096種顏色，不過為了讓主基板1可以旋轉，以致圖十二和圖十三的畫素/子畫素密度比圖十的畫素或圖十一的子畫素密度(所指為解析度)還要低。此外，利用圖十、圖十一、圖十二或圖十三的畫素/子畫素排列時，由於每一畫素/子畫素第二片偏振片5的第二穿透軸51方向皆一致，故可使用單一第二偏振片5覆蓋所有畫素/子畫素。由以上可知，顯見本發明具有一定程度上的進步性及實用性。由上所述者僅為用以解釋本發明之較佳實施例，並非企圖據以對本發明做任何形式上之限制，是以，凡有在相同之發明精神下所做有關本發明之任何修飾或變更者，為其他可據以實施之型態且具有相同效果者，皆仍應包括在本發明意圖保護之範疇內。 Finally, in order to protect the second polarizer 5 from external influences in the present invention, a protective member 7 is further laid on the top surface of the second polarizer 5, and an anti-reflection film is further plated on the top surface of the protective member 7 8. This setting can also reduce the reflection caused by different interfaces, thereby increasing the intensity of incident light. In addition, the foregoing description of the present invention can be applied to the screen of electronic paper, e-book, and folding mobile phone, so please refer to tenth and eleventh As shown in the figure, taking electronic paper as an example, if the paper size of the electronic paper is A4, then the present invention belongs to a circular pixel/circular sub-pixel in the displayed screen in A4 size, so multiple books can be used The invented circular pixels/circular sub-pixels are arranged to form an electronic paper-sized picture. For this arrangement, please refer to the paper (APSIPA Trans.Signal Inf.Process.1,1-10(2012); DOI: 10.1017/ATSIP. 2012.3), each circular pixel/circular sub-pixel has an independent micromotor 22 and is controlled by each independent driving transistor 21, and each independent driving transistor 21 is all controlled by a host computer Therefore, when the electronic paper is displayed in black and white, as shown in the tenth figure, for each circular pixel, the main substrate 1 of each circular pixel can be adjusted through the control of each micromotor 22 through the host computer. The rotation of the reflector 3 and the first polarizer 4 enables each circular pixel to reflect a specific brightness, so that the entire piece of electronic paper can display various images. In addition, when the electronic paper is displayed in color, each circular pixel in the previous black and white display is regarded as a circular sub-pixel, which can be placed on top of each independent circular sub-pixel (the second polarizer 5) Paste a filter with colors (red (R), green (G) or blue (B)) (as shown in the eleventh picture), at this time every three circular sub-pixels are one Pixels. The three circular sub-pixels are circular sub-pixels with red, green and blue filters attached. The arrangement at this time is RGB delta arrangement. Please refer to the paper (APSIPA Trans.Signal Inf. Process. 1, 1-10(2012); DOI: 10.1017/ATSIP.2012.3), if each circular sub-pixel can display 16 gray levels, then 4096 colors can be displayed in the form of color display. Since the present invention uses the method of rotating the first polarizer 4 to display the bright state, the dark state and the gray-scale state, the suitable shape of the main substrate 1 is circular, and the shapes of the reflector 3 and the first polarizer 4 are also the same as those of the main substrate. 1 is the same, all are circular, and the diameters of the main substrate 1, the first polarizer 4 and the reflector 3 are the same, and the centers of the three are aligned. In summary, the drive transistor 21 is used to control the micromotor 22 to perform forward and reverse rotation operations, and then respectively control the main substrate 1, the reflector 3 and the first polarizer 4 of each independent circular pixel/circular sub-pixel. Rotation is performed to change and adjust the angle between the first penetration axis 41 and the second penetration axis 51 to provide switching between the bright mode, the dark mode and the gray scale mode. Use picture 10 or picture eleven pixel/sub-pixel arrangement to display a specific picture, when switching to the next picture, the micro-electromechanical group 2 in each circular pixel/circular sub-pixel Motor 22, please refer to the paper "Electromagnetic Micromotors-Design, Fabrication and Applications, Micromachines 2014; 5: 929-942", which can directly rotate the first polarizer 4 in each circular pixel/circular sub-pixel The penetration axis 41 reaches a specific angle, so it can be improved as described in the prior art. When the e-reader adopts E-INK technology, there will be a black screen or image retention problem on the switching screen, which can bring more to the user. Good reading experience; the display mode of the reflective electronic display device in this case is not easily affected by temperature; the screen update speed depends on the rotation speed of the micromotor 22 in the electromagnetic micro-electromechanical group 2; in addition, the first polarizer 4 and the reflector 3 are two It can be replaced by a single piece of wire grid reflective polarizer. For this wire grid reflective polarizer, please refer to the two US patents "Dual Mode Reflective/Transmissive Liquid Crystal Display Apparatus. USPatent 5 986 730, Nov. 16, 1999" and "Broadband Wire Grid Polarizer for the Visible Spectrum," US Patent 6 122 103, Sept. 19, 2000"; the gray scale in this case is between the first penetration axis 41 and the second penetration axis 51 (Refer to the eighth figure), the gray scale can be displayed continuously in theory; the above takes the circular main substrate 1 as an example, the actual square or hexagonal main substrate 1 can also be used. Figure 12 shows the square main substrate 1 The substrate 1 is regarded as an arrangement of one pixel; Figure 13 shows the arrangement of the hexagonal main substrate 1 as one pixel. For the hexagonal and square pixels, please refer to the paper (Comparison of square-pixel and hexagonal-pixel resolution in image processing; DOI: 10.1109/CCECE.2002.1013056). Consider the pixels in Figure 12 and Figure 13 as a sub-pixel, and paste filters with red (R), green (G) or blue (B) in the order of Figure 11. Every three sub-pixels are one pixel. If each square or hexagonal sub-pixel can display 16 gray levels, then 4096 colors can be displayed in the same color display mode, but in order to allow the main substrate 1 to rotate, so The pixel/sub-pixel density of Fig. 12 and Fig. 13 is lower than that of Fig. 10 or the sub-pixel density of Fig. 11 (referred to as resolution). In addition, when the pixel/sub-pixel arrangement of FIG. 10, FIG. 11, FIG. 12, or FIG. 13 is used, the direction of the second penetration axis 51 of the second polarizer 5 of each pixel/sub-pixel is They are all the same, so a single second polarizer 5 can be used to cover all pixels/sub-pixels. From the above, it is obvious that the present invention has a certain degree of progress and practicability. The above descriptions are only used to explain the preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Therefore, any modification related to the present invention made under the same inventive spirit Or changes, other types that can be implemented and have the same effect, should still be included in the scope of the present invention.
