Structurally, the second surface 154 is opposite to the first surface 152, the light guide plate 150 is disposed on the first color filter layer 120 and the second color filter layer 130, and the second surface 154 of the light guide plate 150 is adjacent to the first surface The color filter layer 120 and the second color filter layer 130. In addition, the side surface 156 is connected to the first surface 152 and the second surface 154, and the light source 160 is disposed beside the side surface 156 of the light guide plate 150.
於操作上，請看到第1圖，光源160用以發出光線162，光線162入射導光板150之側面156後，由導光板150之第一表面152內側將光線162反射，藉使光線162入射第一顏色濾光層120，並經由顯示面板110反射後，由第一顏色濾光層120射出，再經過導光板150後，讓使用者得以看見反射式顯示器100所顯示之影像。In operation, please see FIG. 1 , the light source 160 is used to emit light 162 . After the light 162 is incident on the side 156 of the light guide plate 150 , the light 162 is reflected by the inner side of the first surface 152 of the light guide plate 150 , so that the light 162 is incident. After being reflected by the display panel 110, the first color filter layer 120 is emitted by the first color filter layer 120, and then passes through the light guide plate 150, so that the user can see the image displayed by the reflective display 100.
請一併參照第1圖與第2圖，與光線162實質上平行之另一光線入射導光板150之側面156後，由導光板150之第一表面152內側將另一光線反射，藉使另一光線入射第二顏色濾光層130，並經由顯示面板110反射後，由第二顏色濾光層130射出，再經過導光板150後，讓使用者得以看見反射式顯示器100所顯示之影像。Referring to FIG. 1 and FIG. 2 together, after another light substantially parallel to the light 162 is incident on the side 156 of the light guide plate 150, another light is reflected by the inner side of the first surface 152 of the light guide plate 150, so that another light is A light is incident on the second color filter layer 130 and reflected by the display panel 110, and then emitted by the second color filter layer 130, and then passed through the light guide plate 150, so that the user can see the image displayed by the reflective display 100.
請參照第2圖，本發明實施例之反射式顯示器100藉由其內之元件的配置方式，使這些光線之其中一者的路徑通過第一顏色濾光層120，而不通過第二顏色濾光層130，或者這些光線之其中一者的路徑通過第二顏色濾光層130，而不通過第一顏色濾光層120，亦即當光線入射導光板150後，在反射式顯示器100內的路徑，僅會通過單種顏色濾光層，從而避免光線之路徑通過不同顏色之彩色濾光層，而導致顏色失真或色純度下降，影響反射式顯示器100之色彩顯示品質的問題。Referring to FIG. 2, the reflective display 100 of the embodiment of the present invention passes the path of one of the light rays through the first color filter layer 120 instead of the second color filter. The light layer 130, or a path of one of the rays, passes through the second color filter layer 130 without passing through the first color filter layer 120, that is, after the light is incident on the light guide plate 150, in the reflective display 100. The path only passes through a single color filter layer, thereby preventing the path of the light from passing through the color filter layers of different colors, resulting in color distortion or color purity degradation, which affects the color display quality of the reflective display 100.
請參照第1圖，導光板150之第一表面152包含複數個微結構158，這些微結構158分佈於第一表面152上，其中當光線162入射導光板150之側面156後，由導光板150之第一表面152內側的這些微結構158將光線162反射。Referring to FIG. 1 , the first surface 152 of the light guide plate 150 includes a plurality of microstructures 158 distributed on the first surface 152 . When the light 162 is incident on the side 156 of the light guide plate 150 , the light guide plate 150 is received by the light guide plate 150 . These microstructures 158 on the inside of the first surface 152 reflect the light 162.
承上所述，這微結構158的每一者可為點狀結構。當光線162入射導光板150之側面156後，由導光板150之第一表面152內側的這些點狀結構158將光線162反射與折射。此外，光源160可為條狀光源，而第一顏色濾光層120及第二顏色濾光層130可為條狀濾光層。於配置上，光源160之長側方向實質上垂直於第一顏色濾光層120及第二顏色濾光層130之長側方向。As noted above, each of the microstructures 158 can be a punctiform structure. When the light ray 162 is incident on the side 156 of the light guide plate 150, the light rays 162 are reflected and refracted by the dot structures 158 inside the first surface 152 of the light guide plate 150. In addition, the light source 160 may be a strip light source, and the first color filter layer 120 and the second color filter layer 130 may be strip filter layers. In the arrangement, the long side direction of the light source 160 is substantially perpendicular to the long side direction of the first color filter layer 120 and the second color filter layer 130.
在此需說明是，光源160之長側方向實質上垂直於第一顏色濾光層120之長側方向，代表光源160之長側方向與第一顏色濾光層120之長側方向大致上垂直。舉例而言，光源160之長側方向與第一顏色濾光層120之長側方向之間的夾角可介於約80度至約100度之間。所謂實質上之意義如前所述，在後文中其所代表之意義亦同，因而在後文中不作贅述。It should be noted that the long side direction of the light source 160 is substantially perpendicular to the long side direction of the first color filter layer 120, and the long side direction of the light source 160 is substantially perpendicular to the long side direction of the first color filter layer 120. . For example, the angle between the long side direction of the light source 160 and the long side direction of the first color filter layer 120 may be between about 80 degrees and about 100 degrees. The so-called substantial meanings are as described above, and the meanings they represent in the following are the same, and therefore will not be described in the following.
導光板150於實作時，可藉由非準直型導光板來實現，例如以包含網點(點狀結構)之導光板來實現，然其並非用以限定本發明，熟知此技藝者可依照實際需求選擇性地採用包含不同幾何形狀之微結構來實現導光板150。When the light guide plate 150 is implemented, it can be realized by a non-collimated light guide plate, for example, a light guide plate including a dot (dot structure), which is not intended to limit the present invention, and those skilled in the art can follow The actual requirements selectively employ a microstructure comprising different geometries to implement the light guide plate 150.

In addition, the reflective display 200 may further include a third color filter layer 240, which may be a blue filter layer, which is not intended to limit the invention, but merely exemplarily illustrates an implementation of the present invention. Structurally, the components in the reflective display 200 are arranged in the same manner as the reflective display 100 in FIG. 1 and will not be described herein.
進一步而言，導光板250包含第一表面252、第二表面254以及側面256，而導光板250的基本結構配置方式相同於第1圖中的導光板150，在此不做贅述。Further, the light guide plate 250 includes the first surface 252, the second surface 254, and the side surface 256, and the basic structure of the light guide plate 250 is the same as that of the light guide plate 150 in FIG. 1 , and details are not described herein.
相較於導光板150，導光板250的不同之處在於其所包含之微結構，導光板250之複數個微結構258的每一者可為V型溝槽，這些V型溝槽相互平行排列。Compared with the light guide plate 150, the light guide plate 250 is different in the microstructure included therein, and each of the plurality of microstructures 258 of the light guide plate 250 may be a V-shaped groove, and the V-shaped grooves are arranged in parallel with each other. .
請參照第3圖，當光線262入射導光板250之側面256後，由導光板250之第一表面252內側的這些V型溝槽將光線262反射，並使光線262近乎垂直地入射第一顏色濾光層220或第二顏色濾光層230，亦即本發明實施例之反射式顯示器200可藉由V型溝槽以對顯示面板210準直出光，光線262經由顯示面板210反射後，反射之光線263、264會有發散角，然而反射之光線263、264基本上僅會通過單種顏色濾光層。Referring to FIG. 3, when the light ray 262 is incident on the side 256 of the light guide plate 250, the V-shaped grooves on the inner side of the first surface 252 of the light guide plate 250 reflect the light 262, and the light 262 is incident on the first color almost vertically.

Instead of passing through the second color filter layer 230, or the path of the light ray 262 passes through the second color filter layer without passing through the first color filter layer, that is, when the light ray 262 is incident on the light guide plate 250, the reflective display 200 The inner path only passes through a single color filter layer, thereby preventing the path of the light 262 from passing through the color filter layers of different colors, resulting in color distortion or color purity degradation, which affects the color display quality of the reflective display 200.
在一實施例中，光源260可為條狀光源，而第一顏色濾光層220及第二顏色濾光層230可為條狀濾光層。於配置上，光源260之長側方向實質上平行於第一顏色濾光層220及第二顏色濾光層230之長側方向，並實質上平行於這些V型溝槽。In an embodiment, the light source 260 can be a strip light source, and the first color filter layer 220 and the second color filter layer 230 can be strip filter layers.
