Description

半穿反式顯示模組Transflective display module

本新型創作是有關於一種顯示模組，且特別是有關於一種半穿反式顯示模組。The novel creation relates to a display module, and more particularly to a transflective display module.

半穿反式顯示模組與一般液晶顯示模組的差異在於半穿反式顯示模組的子畫素除了包括穿透區之外還包括反射區。因此，半穿反式顯示模組可在穿透模式與反射模式之間做切換。常見的穿透模式是以背光模組作為其光源，利用穿過液晶層的背光進行顯示。另一方面，反射模式是以環境光作為其光源，利用反射層將入射液晶層的環境光反射，並搭配濾光圖案及偏光片等設計進行顯示。The difference between a transflective display module and a general liquid crystal display module is that the sub-pixels of the transflective display module include a reflection area in addition to a transmissive area. Therefore, the transflective display module can switch between the transmissive mode and the reflective mode. A common transmission mode uses a backlight module as its light source, and uses a backlight that passes through the liquid crystal layer for display. On the other hand, the reflection mode uses ambient light as its light source, uses a reflection layer to reflect the ambient light incident on the liquid crystal layer, and displays it with a filter pattern and a polarizer.

在半穿反式顯示模組的設計中，除了對比、顯示亮度及色彩飽和度之外，白色色座標（或黑色色座標）也是考量的重點之一。目前調變白色色座標（或黑色色座標）的方式包括調整濾光圖案參數、偏光片設計、液晶盒厚度、配向膜的配向方向及配向膜的預傾角的角度等。在上述方式中，調整濾光圖案參數（例如調整濾光圖案的面積比例）為一種有效方式。例如，當半穿反式顯示模組所顯示的白色偏黃時，可藉由縮減紅色濾光圖案及綠色濾光圖案的面積（例如在紅色濾光圖案及綠色濾光圖案中分別形成開口），來減少白光中的紅光成分以及綠光成分，藉此改善白色色座標偏黃的問題。In the design of the transflective display module, in addition to contrast, display brightness, and color saturation, white coordinates (or black coordinates) are also one of the considerations. The current methods of adjusting the white color coordinates (or black color coordinates) include adjusting the filter pattern parameters, polarizer design, liquid crystal cell thickness, the alignment direction of the alignment film, and the pretilt angle of the alignment film. In the above manner, adjusting the filter pattern parameters (for example, adjusting the area ratio of the filter pattern) is an effective method. For example, when the white displayed by the transflective display module is yellowish, the area of the red filter pattern and the green filter pattern can be reduced (for example, openings are formed in the red filter pattern and the green filter pattern, respectively) , To reduce the red light component and the green light component in white light, thereby improving the problem of yellowish white color coordinates.

圖1為一色域圖，顯示習知半穿反式顯示模組操作於反射模式時於CIE 1931色度座標圖上的色域分布。在圖1中，點P1及點P2分別表示在調整濾光圖案的面積比例前後的白色色座標，而三角形T1及三角形T2分別表示在調整濾光圖案的面積比例前後的色域。從圖1可看出，通過上述優化方式，可使原本偏黃的白色色座標（點P1）往藍色移動，使得優化後的白色色座標（點P2）不顯黃。然而，採用上述優化方式亦會導致色域縮小，亦即上述優化方式會犧牲掉色彩飽和度。此外，濾光圖案中開口的最小尺寸會受限於濾光圖案的製程極限，導致白色色座標的實際偏移量D可能超出設計的或預期的偏移量。也就是說，上述的優化方式容易受到製程極限及製程誤差的影響，缺少了設計的靈活度以及誤差容忍度。FIG. 1 is a color gamut diagram showing a color gamut distribution on a CIE 1931 chromaticity coordinate chart of a conventional transflective display module when operating in a reflective mode. In FIG. 1, points P1 and P2 represent white color coordinates before and after the area ratio of the filter pattern is adjusted, and triangles T1 and T2 represent color gamuts before and after the area ratio of the filter pattern is adjusted, respectively. It can be seen from FIG. 1 that through the above optimization method, the originally yellowish white color coordinate (point P1) can be moved to blue, so that the optimized white color coordinate (point P2) is not yellow. However, adopting the above-mentioned optimization method will also cause the color gamut to shrink, that is, the above-mentioned optimization method will sacrifice color saturation. In addition, the minimum size of the openings in the filter pattern is limited by the process limit of the filter pattern, resulting in the actual offset D of the white color coordinates may exceed the designed or expected offset. In other words, the above-mentioned optimization method is easily affected by process limits and process errors, and lacks design flexibility and error tolerance.

本新型創作提供一種半穿反式顯示模組，其具有設計彈性及良好的色彩表現。The novel creation provides a transflective display module, which has design flexibility and good color performance.

Each pixel includes multiple sub-pixels. Multiple sub-pixels are suitable for outputting light beams of different colors, respectively. Each sub-pixel includes a transmission region, a reflection region, and a filter pattern. The area of the penetration region of at least one sub-pixel is different from the area of the penetration region of another sub-pixel. The plurality of filter patterns of the plurality of sub-pixels have a plurality of openings, and an area of at least one opening is different from an area of the other opening.

在本新型創作的一實施例中，多個子畫素的多個濾光圖案分別具有多個開口或分別具有單一開口。In an embodiment of the novel creation, each of the plurality of filter patterns of the plurality of sub-pixels has a plurality of openings or each has a single opening.

基於上述，在本新型創作實施例的半穿反式顯示模組中，藉由調整反射區或穿透區的面積比例，可使反射率或穿透率進一步提升，且可對白色色座標進行微調，以補償濾光圖案之開口的製程極限及製程誤差對於白色色座標的實際偏移量的影響。因此，本新型創作實施例的半穿反式顯示模組具有設計彈性及良好的色彩表現。Based on the above, in the transflective display module of the novel creative embodiment, by adjusting the area ratio of the reflection area or the penetration area, the reflectance or penetration can be further improved, and the white color coordinates can be adjusted. Fine-tune to compensate the effect of the process limit and process error of the opening of the filter pattern on the actual offset of the white color coordinates.

圖2為本新型創作之一實施例的半穿反式顯示模組200的上視示意圖。為清楚顯示半穿反式顯示模組200中的多個子畫素、多條掃描線SL以及多條資料線DL的相對配置關係，圖2示意性繪示出上述元件，但上述元件實際上位於半穿反式顯示模組200中而不會被使用者瞧見。圖3為圖2中的一個畫素480的上視示意圖。圖4為沿圖3中的剖線I-I’的剖面示意圖。為了使圖式清楚，圖2至圖4未繪示出各構件的細部構造。FIG. 2 is a schematic top view of a transflective display module 200 according to an embodiment of the novel creation. In order to clearly show the relative arrangement relationship of the multiple sub-pixels, multiple scan lines SL, and multiple data lines DL in the transflective display module 200, FIG. 2 schematically illustrates the above components, but the above components are actually located in The transflective display module 200 is not visible to the user. FIG. 3 is a schematic top view of a pixel 480 in FIG. 2. Fig. 4 is a schematic cross-sectional view taken along the line I-I 'in Fig. 3. In order to make the drawings clear, the detailed structure of each component is not shown in FIGS. 2 to 4.

請參照圖2至圖4，半穿反式顯示模組200包括多個畫素480。每一個畫素480包括多個子畫素。在本實施例中，這些子畫素排列成如圖2所示的陣列，且每一個子畫素被相鄰兩條資料線DL（沿第一方向D1延伸的導線）以及相鄰兩條掃描線SL（沿第二方向D2延伸的導線）所圍繞。這些子畫素包括適於輸出紅色光束的多個第一色子畫素480R、適於輸出綠色光束的多個第二色子畫素480G以及適於輸出藍色光束的多個第三色子畫素480B，其中輸出相同顏色的多個子畫素沿第一方向D1排列，且輸出不同顏色的多個子畫素沿第二方向D2交替排列。第一方向D1與第二方向D2相交且例如彼此垂直。此外，半穿反式顯示模組200的每一個畫素480由一個第一色子畫素480R、一個第二色子畫素480G以及一個第三色子畫素480B共同組成。然而，每一個畫素480中不同顏色子畫素的數量、顏色種類及這些畫素或子畫素的排列方式可依需求改變，而不以圖2所顯示的為限。Referring to FIGS. 2 to 4, the transflective display module 200 includes a plurality of pixels 480. Each pixel 480 includes a plurality of sub pixels. In this embodiment, these sub-pixels are arranged in an array as shown in FIG. 2, and each sub-pixel is scanned by two adjacent data lines DL (a wire extending along the first direction D1) and two adjacent pixels. A line SL (a wire extending in the second direction D2) is surrounded. These sub-pixels include a plurality of first dice pixels 480R suitable for outputting a red light beam, a plurality of second-color sub-pixels 480G suitable for outputting a green light beam, and a plurality of third dice pixels suitable for outputting a blue light beam. Pixel 480B, where multiple sub-pixels outputting the same color are arranged along the first direction D1, and multiple sub-pixels outputting different colors are arranged alternately along the second direction D2. The first direction D1 and the second direction D2 intersect and are perpendicular to each other, for example. In addition, each pixel 480 of the transflective display module 200 is composed of a first dice pixel 480R, a second dice pixel 480G, and a third dice pixel 480B. However, the number of different color sub-pixels in each pixel 480, the type of color, and the arrangement of these pixels or sub-pixels can be changed as required, and not limited to what is shown in FIG. 2.

每一個子畫素（如第一色子畫素480R、第二色子畫素480G以及第三色子畫素480B）包括穿透區（如第一穿透區482R、第二穿透區482G以及第三穿透區482B）、反射區（如第一反射區484R、第二反射區484G以及第三反射區484B）以及濾光圖案（如第一濾光圖案486R、第二濾光圖案486G以及第三濾光圖案486B）。穿透區為半穿反式顯示模組200操作於穿透模式時的顯示區域，而反射區為半穿反式顯示模組200操作於反射模式時的顯示區域。濾光圖案位於所述穿透區與反射區中，且濾光圖案重疊於所述穿透區及反射區，使半穿反式顯示模組200無論是操作於穿透模式還式操作於反射模式皆能提供彩色的影像畫面。Each sub-pixel (such as the first dichroic pixel 480R, the second dichroic pixel 480G, and the third dichroic pixel 480B) includes a penetrating region (such as the first penetrating region 482R, the second penetrating region 482G And the third transmission region 482B), the reflection region (such as the first reflection region 484R, the second reflection region 484G, and the third reflection region 484B), and the filter pattern (such as the first filter pattern 486R, the second filter pattern 486G And a third filter pattern 486B). The transmissive area is a display area when the transflective display module 200 is operated in the transmissive mode, and the reflective area is a display area when the transflective display module 200 is operated in the reflective mode. The filter pattern is located in the transmissive region and the reflective region, and the filter pattern overlaps the transmissive region and the reflective region, so that the transflective display module 200 operates in both the transmissive mode and the reflective mode. Both modes can provide color video frames.

如圖3所示，每一個子畫素的面積約為穿透區與反射區的面積總合，且每一個子畫素的濾光圖案的面積小於或等於所述子畫素的面積。圖3示意性繪示出多個子畫素具有相同的面積，且每一個子畫素的濾光圖案的面積等於所述子畫素的正投影的面積。換句話說，第一穿透區482R與第一反射區484R的面積總和等於第二穿透區482G與第二反射區484G的面積總和，第二穿透區482G與第二反射區484G的面積總和等於第三穿透區482B與第三反射區484B的面積總和，且第一濾光圖案486R、第二濾光圖案486G以及第三濾光圖案486B具有相同的面積。然而，在另一實施例中，多個子畫素可具有不同的面積，且不同子畫素的濾光圖案的面積可相同或不同。舉例來說，至少一個子畫素的面積可不同於另一個子畫素的面積，且不同顏色子畫素中的濾光圖案的面積可相同或不同。As shown in FIG. 3, the area of each sub-pixel is approximately the sum of the areas of the transmission region and the reflection region, and the area of the filter pattern of each sub-pixel is less than or equal to the area of the sub-pixel. FIG. 3 schematically illustrates that multiple sub-pixels have the same area, and the area of the filter pattern of each sub-pixel is equal to the area of the orthographic projection of the sub-pixel. In other words, the sum of the areas of the first penetration region 482R and the first reflection region 484R is equal to the sum of the areas of the second penetration region 482G and the second reflection region 484G, and the areas of the second penetration region 482G and the second reflection region 484G. The sum is equal to the sum of the areas of the third transmission region 482B and the third reflection region 484B, and the first filter pattern 486R, the second filter pattern 486G, and the third filter pattern 486B have the same area. However, in another embodiment, the multiple sub-pixels may have different areas, and the areas of the filter patterns of different sub-pixels may be the same or different. For example, the area of at least one sub-pixel may be different from the area of another sub-pixel, and the areas of the filter patterns in different-color sub-pixels may be the same or different.

請參照圖4，半穿反式顯示模組200可包括主動元件陣列基板410（也可稱作第一基板）、彩色濾光基板450（也可稱作第二基板）以及位於彩色濾光基板450與主動元件陣列基板410之間的顯示介質層430。Referring to FIG. 4, the transflective display module 200 may include an active element array substrate 410 (also referred to as a first substrate), a color filter substrate 450 (also referred to as a second substrate), and a color filter substrate. A display medium layer 430 between 450 and the active element array substrate 410.

主動元件陣列基板410包括基板412、反射層414、配向層416、多個主動元件（未繪示）、多條掃描線SL（未繪示於圖4，請參照圖1）、多條資料線DL（未繪示於圖4，請參照圖1）以及周邊線路等。The active device array substrate 410 includes a substrate 412, a reflective layer 414, an alignment layer 416, multiple active devices (not shown), multiple scan lines SL (not shown in FIG. 4, please refer to FIG. 1), and multiple data lines. DL (not shown in Figure 4, please refer to Figure 1) and peripheral lines.

基板412適於承載其他元件，且基板412為透光基板，以避免遮蔽光束。舉例來說，基板412可為玻璃基板或塑膠基板，但不以此為限。The substrate 412 is suitable for carrying other components, and the substrate 412 is a light-transmitting substrate to avoid shielding the light beam. For example, the substrate 412 may be a glass substrate or a plastic substrate, but is not limited thereto.

反射層414設置於基板412上。圖4示意性繪示出反射層414與基板412接觸，然而，反射層414與基板412之間可選擇性地設置有其他元件或膜層，如前述的多個主動元件、多條掃描線、多條資料線以及周邊線路等，但不以此為限。反射層414除了可作為用於驅動顯示介質層430的電極之外，還可用於將環境光反射，使半穿反式顯示模組200操作於反射模式時能提供影像畫面。因此，反射層414位於反射區（包括第一反射區484R、第二反射區484G以及第三反射區484B）中。另一方面，為避免遮蔽來自背光模組（未繪示）的背光，使半穿反式顯示模組200操作於穿透模式時也能提供影像畫面，反射層414沒有位於穿透區（包括第一穿透區482R、第二穿透區482G以及第三穿透區482B）中。The reflective layer 414 is disposed on the substrate 412. FIG. 4 schematically illustrates that the reflective layer 414 is in contact with the substrate 412. However, other elements or film layers may be selectively disposed between the reflective layer 414 and the substrate 412, such as the aforementioned multiple active elements, multiple scan lines, Multiple data lines and peripheral lines, but not limited to this. In addition to being used as an electrode for driving the display medium layer 430, the reflective layer 414 can also be used to reflect ambient light, so that the transflective display module 200 can provide an image when operating in a reflective mode. Therefore, the reflective layer 414 is located in the reflective region (including the first reflective region 484R, the second reflective region 484G, and the third reflective region 484B). On the other hand, in order to avoid shielding the backlight from the backlight module (not shown), the transflective display module 200 can also provide an image when the transflective display module 200 is operated in the transmissive mode. The reflective layer 414 is not located in the transmissive area (including The first penetration region 482R, the second penetration region 482G, and the third penetration region 482B).

配向層416位於反射層414與顯示介質層430之間。配向層416適於使顯示介質層430（如液晶層）中的液晶分子（未繪示）依特定的方向與預定的角度排列。The alignment layer 416 is located between the reflective layer 414 and the display medium layer 430. The alignment layer 416 is suitable for aligning liquid crystal molecules (not shown) in the display medium layer 430 (such as a liquid crystal layer) according to a specific direction and a predetermined angle.

依據不同的需求，主動元件陣列基板410可進一步包括其他元件。相關的內容可參照已知技術，於此不再贅述。According to different requirements, the active device array substrate 410 may further include other components. For related content, refer to known technologies, which will not be repeated here.

彩色濾光基板450包含基板452、多個第一濾光圖案486R（圖4僅示意性繪示出一個）、多個第二濾光圖案486G（圖4僅示意性繪示出一個）、多個第三濾光圖案486B（圖4僅示意性繪示出一個）、配向層456及遮蔽層（未繪示）。The color filter substrate 450 includes a substrate 452, a plurality of first filter patterns 486R (only one is schematically illustrated in FIG. 4), a plurality of second filter patterns 486G (only one is schematically illustrated in FIG. 4), multiple A third filter pattern 486B (only one is schematically shown in FIG. 4), an alignment layer 456, and a shielding layer (not shown).

基板452適於承載其他元件，且基板452為透光基板，以避免遮蔽光束。舉例來說，基板452可為玻璃基板或塑膠基板，但不以此為限。The substrate 452 is suitable for carrying other components, and the substrate 452 is a light-transmitting substrate to avoid shielding the light beam. For example, the substrate 452 may be a glass substrate or a plastic substrate, but is not limited thereto.

多個第一濾光圖案486R、多個第二濾光圖案486G以及多個第三濾光圖案486B設置於基板452上並沿第二方向D2交替排列。圖4示意性繪示出上述濾光圖案與基板452接觸，然而，上述濾光圖案與基板452之間可選擇性地設置有其他元件或膜層。舉例來說，上述濾光圖案與基板452之間可選擇性地設置有遮蔽層，以遮蔽半穿反式顯示模組200中不欲被使用者看到的元件，但不以此為限。在本實施例中，第一色子畫素480R、第二色子畫素480G以及第三色子畫素480B分別為紅色子畫素、綠色子畫素及藍色子畫素。對應地，第一濾光圖案486R適於讓紅色光束通過且將其餘顏色光束濾除。第二濾光圖案486G適於讓綠色光束通過且將其餘顏色光束濾除。第三濾光圖案486B適於讓藍色光束通過且將其餘顏色光束濾除。The plurality of first filter patterns 486R, the plurality of second filter patterns 486G, and the plurality of third filter patterns 486B are disposed on the substrate 452 and are alternately arranged along the second direction D2. FIG. 4 schematically illustrates that the filter pattern is in contact with the substrate 452. However, other elements or film layers may be selectively disposed between the filter pattern and the substrate 452. For example, a shielding layer may be selectively disposed between the filter pattern and the substrate 452 to shield components in the transflective display module 200 that are not intended to be seen by a user, but not limited thereto. In this embodiment, the first dice pixel 480R, the second dice pixel 480G, and the third dice pixel 480B are respectively a red sub-pixel, a green sub-pixel, and a blue sub-pixel. Correspondingly, the first filter pattern 486R is adapted to allow the red light beam to pass and filter out the remaining color light beams. The second filter pattern 486G is suitable for passing the green light beam and filtering out the remaining color light beams. The third filter pattern 486B is adapted to pass the blue light beam and filter out the remaining color light beams.

配向層456位於上述濾光圖案與顯示介質層430之間。配向層456適於使顯示介質層430（如液晶層）中的液晶分子（未繪示）依特定的方向與預定的角度排列。The alignment layer 456 is located between the filter pattern and the display medium layer 430. The alignment layer 456 is suitable for aligning liquid crystal molecules (not shown) in the display medium layer 430 (such as a liquid crystal layer) according to a specific direction and a predetermined angle.

依據不同的需求，彩色濾光基板450也可進一步包括其他元件。相關的內容可參照已知技術，於此不再贅述。According to different needs, the color filter substrate 450 may further include other components. For related content, refer to known technologies, which will not be repeated here.

在本實施例中，每一個子畫素的穿透區及反射區設置於主動元件陣列基板410（即第一基板），且每一個子畫素的濾光圖案設置於彩色濾光基板450（即第二基板），但不以此為限。在另一實施例中，每一個子畫素的濾光圖案也可設置於主動元件陣列基板410（即第一基板）。In this embodiment, the penetration and reflection regions of each sub-pixel are disposed on the active device array substrate 410 (ie, the first substrate), and the filter pattern of each sub-pixel is disposed on the color filter substrate 450 ( (Ie, the second substrate), but not limited to this. In another embodiment, the filter pattern of each sub-pixel may also be disposed on the active device array substrate 410 (ie, the first substrate).

為提高色彩飽和度及優化色域，不同顏色子畫素的穿透區的面積比例可依據不同的設計需求而調整。舉例來說，可調整至少一個顏色子畫素的穿透區的面積，使所述至少一個顏色子畫素的穿透區的面積不同於其餘顏色子畫素的穿透區的面積。在不同顏色子畫素具有相同面積的情況下，當第一色子畫素的穿透區的面積大於第二色子畫素的穿透區的面積時，所述第一色子畫素的反射區的面積會小於所述第二色子畫素的反射區的面積。然而，在不同顏色子畫素具有不同面積的情況下，當第一色子畫素的穿透區的面積大於第二色子畫素的穿透區的面積時，所述第一色子畫素的反射區的面積可能等於、小於或大於所述第二色子畫素的反射區的面積。In order to increase the color saturation and optimize the color gamut, the area ratio of the penetration regions of different color sub-pixels can be adjusted according to different design requirements. For example, the area of the penetration region of at least one color sub-pixel may be adjusted so that the area of the penetration region of the at least one color sub-pixel is different from the area of the penetration regions of the remaining color sub-pixels. In the case where different color sub-pixels have the same area, when the area of the penetrating area of the first color sub-pixel is larger than the area of the penetrating area of the second color sub-pixel, the The area of the reflection area will be smaller than the area of the reflection area of the second dice pixel. However, in the case where different color sub-pixels have different areas, when the area of the penetrating area of the first dice pixel is larger than the area of the penetrating area of the second dice pixel, the first dice picture The area of the reflection area of the pixel may be equal to, smaller than, or larger than the area of the reflection area of the second dice pixel.

在一實施例中，不同顏色子畫素可滿足A1/A3=0.1~10且A2/A3=0.1~10，其中A1為第一色子畫素480R之第一穿透區482R的面積，A2為第二色子畫素480G之第二穿透區482G的面積，且A3為第三色子畫素480B之第三穿透區482B的面積。也就是說，第一色子畫素480R之第一穿透區482R的面積與第三色子畫素480B之第三穿透區482B的面積的比值落在0.1至10的範圍內，且第二色子畫素480G之第二穿透區482G的面積與第三色子畫素480B之第三穿透區482B的面積的比值落在0.1至10的範圍內。In one embodiment, different color sub-pixels can satisfy A1 / A3 = 0.1 ~ 10 and A2 / A3 = 0.1 ~ 10, where A1 is the area of the first penetrating region 482R of the first color sub-pixel 480R, and A2 Is the area of the second penetration region 482G of the second dice pixel 480G, and A3 is the area of the third penetration region 482B of the third dice pixel 480B. That is, the ratio of the area of the first penetrating region 482R of the first dice pixel 480R to the area of the third penetrating region 482B of the third dice pixel 480B falls within the range of 0.1 to 10, and the first The ratio of the area of the second penetrating region 482G of the dichroic pixel 480G to the area of the third penetrating region 482B of the third dichroic pixel 480B falls within the range of 0.1 to 10.

類似地，為提高色彩飽和度及優化色域，不同顏色子畫素的反射區的面積比例亦可依據不同的設計需求而調整。舉例來說，可調整至少一個顏色子畫素的反射區的面積，使所述至少一個顏色子畫素的反射區的面積不同於其餘顏色子畫素的反射區的面積。在不同顏色子畫素具有相同面積的情況下，當第一色子畫素的反射區的面積大於第二色子畫素的反射區的面積時，所述第一色子畫素的穿透區的面積會小於所述第二色子畫素的穿透區的面積。然而，在不同顏色子畫素具有不同面積的情況下，當第一色子畫素的反射區的面積大於第二色子畫素的反射區的面積時，所述第一色子畫素的穿透區的面積可能等於、小於或大於所述第二色子畫素的穿透區的面積。Similarly, in order to increase the color saturation and optimize the color gamut, the area ratio of the reflection regions of different color sub-pixels can also be adjusted according to different design requirements. For example, the area of the reflection area of the at least one color sub-pixel may be adjusted so that the area of the reflection area of the at least one color sub-pixel is different from the area of the reflection areas of the remaining color sub-pixels. In the case where different color sub-pixels have the same area, when the area of the reflection region of the first dice pixel is larger than the area of the reflection region of the second dice pixel, the penetration of the first dice pixel The area of the area will be smaller than the area of the penetrating area of the second dice pixel. However, in the case where different color sub-pixels have different areas, when the area of the reflection region of the first dice pixel is larger than the area of the reflection region of the second dice pixel, the The area of the penetration area may be equal to, smaller than, or larger than the area of the penetration area of the second dice pixel.

在一實施例中，不同顏色子畫素可滿足B1/B3=0.1~10且B2/B3=0.1~10，其中B1為第一色子畫素480R之第一反射區484R的面積，B2為第二色子畫素480G之第二反射區484G的面積，且B3為第三色子畫素480B之第三反射區482B的面積。也就是說，第一色子畫素480R之第一反射區484R的面積與第三色子畫素480B之第三反射區482B的面積的比值落在0.1至10的範圍內，且第二色子畫素480G之第二反射區484G的面積與第三色子畫素480B之第三反射區482B的面積的比值落在0.1至10的範圍內。In an embodiment, different color sub-pixels can satisfy B1 / B3 = 0.1 ~ 10 and B2 / B3 = 0.1 ~ 10, where B1 is the area of the first reflection area 484R of the first color sub-pixel 480R, and B2 is The area of the second reflection area 484G of the second dice pixel 480G, and B3 is the area of the third reflection area 482B of the third dice pixel 480B. That is, the ratio of the area of the first reflection area 484R of the first dice pixel 480R to the area of the third reflection area 482B of the third dice pixel 480B falls within the range of 0.1 to 10, and the second color The ratio of the area of the second reflection area 484G of the sub-pixel 480G to the area of the third reflection area 482B of the third-color sub-pixel 480B falls within a range of 0.1 to 10.

為提高色彩飽和度及優化色域，不同顏色子畫素的穿透區及反射區的面積比例可一併依據不同的設計需求而調整。此外，為滿足上述反射區與穿透區的面積比例關係，不同顏色子畫素可具有相同、至少部分相同或不同的面積。In order to increase the color saturation and optimize the color gamut, the area ratios of the penetration and reflection areas of different color sub-pixels can be adjusted according to different design requirements. In addition, in order to satisfy the area ratio relationship between the reflection area and the penetration area, different color sub-pixels may have the same, at least partially the same, or different areas.

圖5為一色域圖，顯示本新型創作之半穿反式顯示模組200（參照圖2）操作於反射模式時於CIE 1931色度座標圖上的色域分布。請參照圖2及圖5，當半穿反式顯示模組200操作於反射模式時的白色色座標（參照點P3）偏黃時，可藉由調整不同顏色子畫素的穿透區及/或反射區之面積比例，來改變白色色座標的位置。舉例來說，如圖3所示，可縮小第一反射區484R及第二反射區484G的面積（或增加第一穿透區482R及第二穿透區482G的面積），以減少反射模式下自畫素480輸出的光束中的紅光成分以及綠光成分，進而使白色色座標由圖5中的點P3位移至點P4。所述縮小第一反射區484R及第二反射區484G的面積例如是透過縮小反射層414（參照圖4）在第一色子畫素480R及第二色子畫素480G中佔據的面積來達成。FIG. 5 is a color gamut diagram showing the color gamut distribution on the CIE 1931 chromaticity coordinate chart when the transflective display module 200 (refer to FIG. 2) of the present invention is operated in the reflection mode. Please refer to FIG. 2 and FIG. 5, when the transflective display module 200 is operated in the reflection mode, the white color coordinates (reference point P3) are yellow, and the penetration regions of different color sub-pixels can be adjusted by / Or the area ratio of the reflection area to change the position of the white coordinates. For example, as shown in FIG. 3, the areas of the first reflection region 484R and the second reflection region 484G can be reduced (or the areas of the first transmission region 482R and the second transmission region 482G can be increased) to reduce the reflection mode. The red light component and the green light component in the light beam output from the pixel 480 further shift the white color coordinate from the point P3 to the point P4 in FIG. 5. The reduction of the areas of the first reflection region 484R and the second reflection region 484G is achieved by reducing the area occupied by the reflection layer 414 (see FIG. 4) in the first dice pixel 480R and the second dice pixel 480G. .

圖3示意性繪示出第三色子畫素480B之第三反射區484B的面積大於第二色子畫素480G之第二反射區484G的面積，且第二色子畫素480G之第二反射區484G的面積大於第一色子畫素480R之第一反射區484R的面積。然而，不同顏色子畫素的穿透區及/或反射區之面積比例可依據不同的情況（如白色色座標所需調整的位移量及方向）進行調整，且所述調整不限於對多個顏色子畫素的穿透區（或反射區）的面積進行調整。在一實施例中，可調整一個或多個顏色子畫素的穿透區（或反射區）的面積，使兩個以上不同顏色子畫素的穿透區（或反射區）的面積不同。FIG. 3 schematically illustrates that the area of the third reflection region 484B of the third dice pixel 480B is larger than the area of the second reflection region 484G of the second dice pixel 480G, and the second The area of the reflective area 484G is larger than the area of the first reflective area 484R of the first dice pixel 480R. However, the area ratios of the penetrating and / or reflecting regions of different color sub-pixels can be adjusted according to different situations (such as the amount of displacement and direction that need to be adjusted for white coordinates), and the adjustment is not limited to multiple The area of the penetration (or reflection) area of the color sub-pixel is adjusted. In one embodiment, the areas of the penetration areas (or reflection areas) of one or more color sub-pixels may be adjusted so that the areas of the penetration areas (or reflection areas) of two or more different color sub-pixels are different.

由於可以不用藉由在濾光圖案中形成開口來調整白色色座標的位置，因此可以不犧牲色彩飽和度，即維持色域（圖5中三角形T1所框出的範圍）。此外，反射層414之圖案化的光罩成本較彩色濾光圖案之圖案化的光罩成本低，因此藉由反射層之圖案化來優化白色色座標的設計成本較低，且利於降低優化之成本。另外，反射層之圖案化的製程精度較彩色濾光圖案之圖案化的製程精度高，因此圖5中白色色座標的實際偏移量DA（最小微調距離）可小於圖1中白色色座標的實際偏移量D（最小微調距離）。也就是說，藉由此優化方式能夠對白色色座標進行更細微的調整，且白色色座標的調整空間較大。Since it is not necessary to adjust the position of the white color coordinates by forming an opening in the filter pattern, the color gamut can be maintained without sacrificing color saturation (the range framed by the triangle T1 in FIG. 5). In addition, the cost of the patterned mask of the reflective layer 414 is lower than the cost of the patterned mask of the color filter pattern. Therefore, the cost of optimizing the design of the white coordinates by the patterning of the reflective layer is lower, and it is beneficial to reduce the optimization. cost. In addition, the accuracy of the patterning process of the reflective layer is higher than that of the color filter pattern. Therefore, the actual offset DA (minimum fine-tuning distance) of the white color coordinates in FIG. 5 can be smaller than that of the white color coordinates in FIG. 1. Actual offset D (minimum fine-tuning distance). That is, the white coordinate can be fine-tuned by this optimization method, and the white coordinate adjustment space is large.

在一實施例中，為提高反射率，可增加每一子畫素的反射區之面積。舉例來說，當將第一反射區484R、第二反射區484G及第三反射區482B的面積一起增大k倍時，反射率亦可提升k倍。在另一實施例中，可縮小每一子畫素的反射區之面積，以提高穿透率。在此情況下，k值可小於1。舉例來說，k值之範圍約落在1.5至0.67的範圍內。In one embodiment, in order to increase the reflectivity, the area of the reflection area of each sub-pixel may be increased. For example, when the areas of the first reflection region 484R, the second reflection region 484G, and the third reflection region 482B are increased by a factor of k, the reflectance can also be increased by a factor of k. In another embodiment, the area of the reflection area of each sub-pixel can be reduced to increase the transmittance. In this case, the value of k may be less than 1. For example, the range of k values falls approximately within the range of 1.5 to 0.67.

在上述實施例中，彩色濾光圖案（包括第一濾光圖案486R、第二濾光圖案486G以及第三濾光圖案486B）不具有開口。然而，在其他實施例中，彩色濾光圖案亦可具有開口。圖6為本新型創作之又一實施例的半穿反式顯示模組700的一個畫素780的上視示意圖。圖7A至圖7C分別為沿圖6中的剖線II-II’、III-III’、IV-IV’的剖面示意圖。In the above embodiment, the color filter pattern (including the first filter pattern 486R, the second filter pattern 486G, and the third filter pattern 486B) does not have an opening. However, in other embodiments, the color filter pattern may have an opening. FIG. 6 is a schematic top view of a pixel 780 of the transflective display module 700 according to another embodiment of the novel creation. 7A to 7C are schematic cross-sectional views taken along section lines II-II ', III-III', and IV-IV 'in FIG. 6, respectively.

請參照圖6至圖7C，半穿反式顯示模組700與圖3及圖4的半穿反式顯示模組200的主要差異如下所述。在半穿反式顯示模組700中，多個子畫素的多個濾光圖案具有多個開口。此處，開口定義為濾光圖案中無濾光材料（如樹脂）覆蓋的區域，且此區域可填充或不填充透光的保護層。此外，多個子畫素的多個濾光圖案具有多個開口不限定每一個子畫素的濾光圖案皆具有開口，而是指至少部分的子畫素的濾光圖案具有開口。也就是說，有一部分的子畫素的濾光圖案可不具有開口，或者每一個子畫素的濾光圖案皆具有開口。此外，多個子畫素的多個濾光圖案可分別具有單一開口或多個開口。更具體來說，不同濾光圖案可具有不同數量的開口。或者，不同濾光圖案可具有相同數量的開口。例如，不同濾光圖案可分別具有單一開口或分別具有多個開口。6 to 7C, the main differences between the transflective display module 700 and the transflective display module 200 of FIGS. 3 and 4 are as follows. In the transflective display module 700, a plurality of filter patterns of a plurality of sub-pixels have a plurality of openings. Here, the opening is defined as an area in the filter pattern that is not covered by a filter material (such as resin), and this area may or may not be filled with a light-transmitting protective layer. In addition, the multiple filter patterns of multiple sub-pixels have multiple openings. It is not limited that the filter patterns of each sub-pixel have openings, but it means that at least part of the filter patterns of sub-pixels have openings. That is, a part of the sub-pixel filter patterns may not have openings, or each of the sub-pixel filter patterns may have openings. In addition, the plurality of filter patterns of the plurality of sub-pixels may have a single opening or a plurality of openings, respectively. More specifically, different filter patterns may have different numbers of openings. Alternatively, different filter patterns may have the same number of openings. For example, different filter patterns may each have a single opening or multiple openings.

在本實施例中，第一色子畫素780R包括第一穿透區482R、第一反射區484R以及第一濾光圖案786R，且第一濾光圖案786R具有開口788R。第二色子畫素780G包括第二穿透區482G、第二反射區484G以及第二濾光圖案786G，且第二濾光圖案786G具有開口788G。第三色子畫素780B包括第三穿透區482B、第三反射區482B以及第三濾光圖案786B，且第三濾光圖案786B具有開口788B。開口788R與開口788B具有相同的面積，且開口788G的面積不同於（例如大於）開口788R以及開口788B的面積。然而，每一個濾光圖案的開口的面積、形狀及其於濾光圖案中的位置可依需求改變，而不以圖6所顯示的為限。舉例來說，開口788R、開口788G及開口788B可具有不同面積。In this embodiment, the first dice pixel 780R includes a first transmission region 482R, a first reflection region 484R, and a first filter pattern 786R. The first filter pattern 786R has an opening 788R. The second color pixel 780G includes a second transmission region 482G, a second reflection region 484G, and a second filter pattern 786G. The second filter pattern 786G has an opening 788G. The third dice pixel 780B includes a third transmission region 482B, a third reflection region 482B, and a third filter pattern 786B. The third filter pattern 786B has an opening 788B. The opening 788R has the same area as the opening 788B, and the area of the opening 788G is different (for example, larger than) the area of the opening 788R and the opening 788B. However, the area, shape, and position of the opening of each filter pattern can be changed as required, and is not limited to what is shown in FIG. 6. For example, the openings 788R, 788G, and 788B may have different areas.

為提高色彩飽和度及優化色域，不同顏色子畫素的濾光圖案的開口、反射區與穿透區的面積比例可依據不同的設計需求而調整。透過對濾光圖案之開口以及反射區（或穿透區）的面積比例（即不同顏色子畫素中的反射層的面積）進行設計，可有效提升設計之靈活度。In order to improve the color saturation and optimize the color gamut, the area ratios of the openings, reflection areas, and penetration areas of the filter patterns of different color sub-pixels can be adjusted according to different design requirements. By designing the opening ratio of the filter pattern and the area ratio of the reflection area (or transmission area) (that is, the area of the reflection layer in different color sub-pixels), the flexibility of the design can be effectively improved.

在一實施例中，不同顏色子畫素可滿足(C1+C2+C3)＜2000平方微米，(B1-C1)/(B3-C3)以及(B2-C2)/(B3-C3)分別落在0.2至5的範圍內，且A1/A3以及A2/A3分別落在0.1至10的範圍內，其中C1為第一濾光圖案786R的開口788R的開口面積，C2為第二濾光圖案786G的開口788G的開口面積，且C3為第三濾光圖案786B的開口788B的開口面積。(B1-C1)表示的是第一色子畫素780R之第一反射區484R的面積扣除第一濾光圖案786R的開口788R的開口面積，也就是第一反射區484R中濾光材料所佔據的面積。同理，(B2-C2)表示第二反射區484G中濾光材料所佔據的面積。(B3-C3)表示第三反射區484B中濾光材料所佔據的面積。In one embodiment, sub-pixels of different colors can satisfy (C1 + C2 + C3) <2000 square micrometers, and (B1-C1) / (B3-C3) and (B2-C2) / (B3-C3) fall Within the range of 0.2 to 5, and A1 / A3 and A2 / A3 fall within the range of 0.1 to 10, where C1 is the opening area of the opening 788R of the first filter pattern 786R, and C2 is the second filter pattern 786G The opening area of the opening 788G, and C3 is the opening area of the opening 788B of the third filter pattern 786B. (B1-C1) represents the area of the first reflection area 484R of the first dice pixel 780R minus the opening area of the opening 788R of the first filter pattern 786R, that is, the area occupied by the filter material in the first reflection area 484R Area. Similarly, (B2-C2) represents the area occupied by the filter material in the second reflection region 484G. (B3-C3) represents an area occupied by the filter material in the third reflection region 484B.

詳細而言，可依A1/A3以及A2/A3設計三個不同顏色子畫素的穿透區的面積比例，並依(B1-C1)/(B3-C3)以及(B2-C2)/(B3-C3)設計三個不同顏色子畫素的反射區的面積比例。當三個子畫素的開口面積的總和小於2000平方微米時，濾光圖案之開口面積可能逼近甚至超出製程極限。如圖6所示，當開口788B及開口788R設計的線寬（如開口在第一方向D1上的寬度）小於製程所能達到的線寬時，實際製作出來的開口788B的線寬LWB及實際製作出來的開口788R的線寬LWR約為製程所能達到的線寬，因而產生設計值與實際值的落差。此時，白色色座標的實際偏移量（最小微調距離）會超出設計的偏移量。在此情況下，可藉由調整穿透區及/或反射區的面積（反射層的面積），來達成顏色之平衡，並補償濾光圖案之開口的製程極限及製程誤差對於白色色座標的實際偏移量的影響，使調整後的白色色座標的實際偏移量（最小微調距離，如圖8的白色色座標的實際偏移量DB）可小於圖1中白色色座標的實際偏移量D（最小微調距離）。也就是說，藉由此方式能夠對白色色座標進行微調，使白色色座標的調整空間較先前技術大，且不會進一步犧牲色彩飽和度。In detail, the area ratio of the penetration areas of three different color sub-pixels can be designed according to A1 / A3 and A2 / A3, and according to (B1-C1) / (B3-C3) and (B2-C2) / ( B3-C3) Design the area ratio of the reflection area of the three different color sub-pixels. When the sum of the opening areas of the three sub-pixels is less than 2000 square micrometers, the opening area of the filter pattern may approach or even exceed the process limit. As shown in FIG. 6, when the designed line width of the opening 788B and the opening 788R (such as the width of the opening in the first direction D1) is smaller than the line width that can be achieved by the manufacturing process, the actually produced line width LWB of the opening 788B and the actual The line width LWR of the manufactured opening 788R is about the line width that can be achieved in the manufacturing process, so there is a difference between the design value and the actual value. At this time, the actual offset (minimum fine-tuning distance) of the white color coordinates will exceed the designed offset. In this case, the color balance can be achieved by adjusting the area of the penetrating and / or reflecting area (the area of the reflective layer), and compensating the process limit and process error of the opening of the filter pattern for the white color coordinates. The effect of the actual offset makes the adjusted actual offset of the white color coordinates (minimum fine-tuning distance, as shown in the actual offset of the white color coordinates DB in Figure 8) smaller than the actual offset of the white color coordinates in Figure 1. D (minimum fine-tuning distance). That is, in this way, the white color coordinates can be fine-tuned, so that the adjustment space of the white color coordinates is larger than that of the prior art, and the color saturation is not further sacrificed.

在一實施例中，也可在調整穿透區及/或反射區的面積（反射層的面積）之後，進一步藉由調整三個不同顏色子畫素的開口面積來提升反射率或穿透率。In an embodiment, after adjusting the area of the penetrating area and / or the reflecting area (the area of the reflective layer), the reflectance or transmittance can be further improved by adjusting the opening areas of three different color sub-pixels. .

圖8為一色域圖，顯示本新型創作之半穿反式顯示模組700操作於反射模式時於CIE 1931色度座標圖上的色域分布。在圖6中，開口788B及開口788R的面積大小受限於製程極限而無法進一步縮小以符合設計值，造成圖8中白色色座標（點P5）偏綠。此時，可藉由加大第一反射區784R以及第三反射區784B的面積（即縮減第一穿透區782R以及第三穿透區782B的面積），來優化白色色座標，使白色色座標由點P5位移至點P6，從而具有良好的色彩表現。在本實施例中，(B1-C1):(B2-C2):(B3-C3)=0.9:0.8:1，但本新型創作不以此為限。FIG. 8 is a color gamut diagram showing the color gamut distribution on the CIE 1931 chromaticity coordinate diagram when the transflective display module 700 of the present invention is operated in the reflection mode. In FIG. 6, the area sizes of the openings 788B and 788R are limited by the process limits and cannot be further reduced to meet the design values, resulting in the white color coordinates (point P5) in FIG. 8 being greenish. At this time, by increasing the areas of the first reflection area 784R and the third reflection area 784B (that is, reducing the areas of the first penetration area 782R and the third penetration area 782B), the white color coordinates can be optimized to make the white color The coordinates are shifted from point P5 to point P6, so that it has good color performance. In this embodiment, (B1-C1) :( B2-C2) :( B3-C3) = 0.9: 0.8: 1, but the new creation is not limited to this.

綜上所述，本新型創作之半穿反式顯示模組透過調整反射區或穿透區之面積比例，可使反射率或穿透率進一步提升，且可對白色色座標進行微調，以補償濾光圖案之開口的製程極限及製程誤差對於白色色座標的實際偏移量的影響，並維持色彩飽和度。並且，相較於濾光圖案之圖案化，反射層之圖案化的光罩成本較低且製程精度較高。此外，本新型創作之顯示模組各子畫素間面積可相等；倘不相等時其最大子畫素面積與最小子畫素面積比例約為2。因此，能夠對白色色座標進行更細微的調整，且白色色座標的調整空間較大。是以，本新型創作實施例的半穿反式顯示模組具有設計彈性及良好的色彩表現。To sum up, the transflective display module of the new creation can further improve the reflectance or transmittance by adjusting the area ratio of the reflection area or the penetration area, and can fine-tune the white coordinates to compensate The effect of the process limit and process error of the opening of the filter pattern on the actual offset of the white color coordinates, and maintain the color saturation. In addition, compared with the patterning of the filter pattern, the patterned photomask of the reflective layer has lower cost and higher process accuracy. In addition, the area of each sub-pixel of the display module created by the new model may be equal; if it is not equal, the ratio of the maximum sub-pixel area to the minimum sub-pixel area is about 2. Therefore, it is possible to perform finer adjustments on the white color coordinates, and the adjustment space of the white color coordinates is large. Therefore, the transflective display module of the novel creative embodiment has design flexibility and good color performance.
