請參照圖1至圖4,眼球訓練裝置10包括載體100與穿透式液晶元件110。載體100具有透視區STR。穿透式液晶元件110設置於載體100上,且重疊於透視區STR。在本實施例中,眼球訓練裝置10可以是穿戴式裝置,例如智慧眼鏡。更具體地說,載體100可以是用於配戴在使用者頭部的鏡框。此鏡框具有對應使用者雙眼而設的開孔100a與開孔100b,且這兩開孔可定義出載體100的兩透視區STR。對應地,本實施例的穿透式液晶元件110的數量為兩個(例如穿透式液晶元件110R與穿透式液晶元件110L),分別設置於載體100對應使用者右眼的開孔100a與使用者左眼的開孔100b內。Referring to FIGS. 1 to 4 , the
然而,本發明不限於此,根據其他未示出的實施例,眼球訓練裝置的載體也可以是固定式的基座,且此基座還具有適於讓使用者抵靠的限位結構。此限位結構可確保使用者的雙眼能透過兩開孔而視覺穿透式液晶元件的影像或後方的景物。However, the present invention is not limited thereto, and according to other unshown embodiments, the carrier of the eye training device may also be a fixed base, and the base also has a limiting structure suitable for the user to abut against.

進一步而言,穿透式液晶元件110包括基板111、基板112、液晶層LCL、偏光片POL1及偏光片POL2。偏光片POL1與偏光片POL2分別設置於基板111與基板112上,且基板111與基板112位於偏光片POL1與偏光片POL2之間。液晶層LCL設置於基板111與基板112之間。為了實現穿透式液晶元件110的輕薄化,基板111與基板112的材質可包括聚醯亞胺(polyimide,PI)、聚對苯二甲酸乙二酯(polyethylene terephthalate,PET)、或其他合適的高分子材料。然而,本發明不限於此,根據其他實施例,基板111與基板112的材質也可以是玻璃、石英或其他合適的硬質材料。Further, the transmissive
更具體地說,穿透式液晶元件110可以是電控液晶盒。因此,穿透式液晶元件110還可選擇性地包括多條第一訊號線SL1、多條第二訊號線SL2與遮光圖案BM。這些第一訊號線SL1沿著方向X排列且在方向Y上延伸,這些第二訊號線SL2沿著方向Y排列且在方向X上延伸。亦即,這些第二訊號線SL2相交於這些第一訊號線SL1。為了確保第一訊號線SL1與第二訊號線SL2的電性獨立,第一訊號線SL1與第二訊號線SL2之間設有絕緣層113。More specifically, the transmissive
另一方面,遮光圖案BM在基板111的法線方向(例如方向Z)上完全重疊於這些第一訊號線SL1與這些第二訊號線SL2,並具有重疊於透視區STR的多個開口OP。這些開口OP可定義出穿透式液晶元件110的多個畫素區,且這些畫素區分別設有多個畫素結構PX。亦即,這些畫素結構PX分別重疊於這些開口OP。在本實施例中,遮光圖案BM是設置在基板112上,第一訊號線SL1與第二訊號線SL2是設置在基板111上,但不以此為限。在其他實施例中,遮光圖案BM、第一訊號線SL1與第二訊號線SL2也可設置在同一基板上。On the other hand, the light shielding pattern BM completely overlaps the first signal lines SL1 and the second signal lines SL2 in the normal direction of the substrate 111 (eg, the direction Z), and has a plurality of openings OP overlapping the see-through area STR. The openings OP can define a plurality of pixel regions of the transmissive
在本實施例中,畫素結構PX包括彼此電性連接的主動元件T與畫素電極PE。主動元件T電性連接對應的一條第一訊號線SL1與對應的一條第二訊號線SL2。舉例而言,第一訊號線SL1例如是掃描線(scan line),第二訊號線SL2例如是資料線(data line),而主動元件T的閘極與源極分別電性連接第一訊號線SL1與第二訊號線SL2。也就是說,本實施例的穿透式液晶元件110為具有主動式陣列(active matrix)的電控液晶盒,但本發明不以此為限。為了確保畫素電極PE與第二訊號線SL2之間的電性獨立以及畫素電極PE的平整性,畫素電極PE與第二訊號線SL2之間設有平坦層114。In this embodiment, the pixel structure PX includes an active element T and a pixel electrode PE that are electrically connected to each other. The active element T is electrically connected to a corresponding first signal line SL1 and a corresponding second signal line SL2. For example, the first signal line SL1 is, for example, a scan line, the second signal line SL2 is, for example, a data line, and the gate and source of the active element T are respectively electrically connected to the first signal line SL1 and the second signal line SL2. That is to say, the transmissive
特別一提的是,遮光圖案BM的多個開口OP所占區域於基板111的垂直投影面積與透視區STR所占區域於基板111的垂直投影面積的百分比值大於95%。據此,可明顯降低這些畫素結構PX之間的非透光區(即遮光圖案BM所占區域)的可視性(visibility),有助於改善使用者在眼球訓練時與周圍環境的互動體驗,並提升視覺上的舒適度。在一較佳的實施例中,遮光圖案BM的多個開口OP所占區域於基板111的垂直投影面積與透視區STR所占區域於基板111的垂直投影面積的百分比值可大於98%。In particular, the percentage of the area occupied by the openings OP of the shading pattern BM on the vertical projected area of the
舉例來說,遮光圖案BM的開口OP在方向X與方向Y上分別具有寬度W1與寬度W2,在方向X上排列且相鄰的任兩開口OP在方向X上具有間距S1,在方向Y上排列且相鄰的任兩開口OP在方向Y上具有間距S2。為了讓穿透式液晶元件110具有較高的開口率(aperture ratio),間距S1與寬度W1的比值及/或間距S2與寬度W2的比值可介於0.01至0.03之間,例如:間距S1及/或間距S2小於9微米,而寬度W1及/或寬度W2大於500微米。For example, the openings OP of the light shielding pattern BM have widths W1 and W2 in the direction X and direction Y respectively, and any two adjacent openings OP arranged in the direction X have a distance S1 in the direction X and a distance S1 in the direction Y Any two openings OP that are arranged and adjacent to each other have an interval S2 in the direction Y. As shown in FIG. In order for the transmissive
進一步而言,穿透式液晶元件110更包括電極層EL與覆蓋層115。電極層EL設置於液晶層LCL的一側,並與位在液晶層LCL另一側的畫素電極PE相對。覆蓋層115夾設於電極層EL與遮光圖案BM之間。在本實施例中,多個畫素結構PX的多個畫素電極PE彼此電性獨立,而電極層EL為整面電極(即未經圖案化的導電層),但本發明不以此為限。為了取得較佳的透視效果,穿透式液晶元件110的畫素電極PE與電極層EL例如是光穿透式電極,光穿透式電極的材質包括銦錫氧化物、銦鋅氧化物、鋁錫氧化物、鋁鋅氧化物、或其它合適的氧化物、極薄的金屬、奈米碳管、石墨烯或者是上述至少兩者之堆疊層。Further, the transmissive
特別說明的是,穿透式液晶元件110的液晶層LCL可採用扭轉向列型液晶(Twisted Nematic Liquid Crystal,TN-LC)模式、超扭轉向列行液晶(Super Twisted Nematic Liquid Crystal,STN-LC)模式、垂直排列型液晶(Vertical Alignment Liquid Crystal,VA-LC)模式、或電控雙折射型液晶(Electrically controlled birefringence,ECB)模式來進行操作,但不以此為限。Specifically, the liquid crystal layer LCL of the transmissive
為了避免使用者無法經由眼球訓練裝置10接收來自外界或其他顯示裝置的偏振光(例如線偏振光),穿透式液晶元件110還可選擇性地包括四分之一波片116。四分之一波片116重疊設置於偏光片POL2與偏光片POL1,且偏光片POL2位於四分之一波片116與液晶層LCL之間。亦即,四分之一波片116是設置在偏光片POL2遠離液晶層LCL的一側。In order to prevent the user from being unable to receive polarized light (eg, linearly polarized light) from the outside world or other display devices through the
另一方面,眼球訓練裝置10更包括電路軟板120與控制單元200。電路軟板120接合(bonding)在穿透式液晶元件110的周邊,以電性連接第一訊號線SL1與第二訊號線SL2。控制單元200設置於載體100上,並經由電路軟板120與穿透式液晶元件110電性連接。此處的電路軟板120例如是覆晶軟板(chip on film,COF)或傳輸電路板,但不以此為限。在本實施例中,眼球訓練裝置10可經由無線通訊(例如藍芽、近場通訊或無線熱點等方式)與外部裝置300(例如手機、電腦、平板、具有人工智慧的裝置、或聯網裝置)進行訊號的交換。然而,在其他實施例中,眼球訓練裝置也可經由實體線材與外部裝置連接,以進行訊號的傳遞。當然,眼球訓練裝置10也可設有儲存元件,以存放執行程序及相關的設定參數。亦即,眼球訓練裝置10也可單獨操作。On the other hand, the
由於穿透式液晶元件110的多個畫素結構PX可獨立地控制上述多個畫素區(即多個開口OP所定義的區域)的透光度,因此在透視區STR內的不同位置上可形成具有不同大小或光強度的光點,以達到眼球移動的引導或訓練功能。以下將針對眼球訓練裝置10的兩種操作模式進行示範性地說明。Since the plurality of pixel structures PX of the transmissive
請參照圖5A及圖5B,當眼球訓練裝置10操作在眼球移動的導引模式時,穿透式液晶元件110R會將透視區STR的大部分區域都切換成不透光,而在預定位置的畫素區則切換為預定的透光度以呈現出導引指標(如圖5A的十字記號)。如圖5A所示,當透視區STR的左上角出現導引指標時,可吸引使用者轉動右眼球,使其注目點朝向第一位置P1移動。接著,將導引指標設置在透視區STR的右側,讓使用者再一次地轉動右眼球,使其注目點朝向第二位置P2移動,如圖5B所示。透過導引指標在透視區STR的多個位置之間移動,來驅使眼球進行對應的轉動,以達到眼球訓練的目的。需說明的是,對應使用者左眼的穿透式液晶元件110L也是以相似的方式進行眼球的訓練,於此便不再贅述。Referring to FIGS. 5A and 5B , when the
另一方面,眼球訓練裝置10還可用於弱視患者的視力訓練。例如:當患者的左眼視力較右眼視力差時,可調整眼球訓練裝置10,使其對應患者左眼的穿透式液晶元件110L的多個畫素區(即重疊於透視區STRb的多個開口OP所定義的區域)都具有高透光度,而對應患者右眼的穿透式液晶元件110R的多個畫素區(即重疊於透視區STRa的多個開口OP所定義的區域)的透光度則由透視區STRa的中心朝周圍遞減,如圖6所示。如此一來,在患者訓練左眼視力的同時,右眼視力可被降低至一預定值,有助於減緩患者在訓練過程中所產生的不適感,並增加療程的設計彈性。On the other hand, the
以下將列舉另一些實施例以詳細說明本揭露,其中相同的構件將標示相同的符號,並且省略相同技術內容的說明,省略部分請參考前述實施例,以下不再贅述。Hereinafter, other embodiments will be listed to describe the present disclosure in detail, wherein the same components will be marked with the same symbols, and the description of the same technical content will be omitted.

Referring to FIGS. 7 and 8 , the difference between the transmissive
詳細而言,穿透式液晶元件110A的多條第一訊號線SL1與多條第二訊號線SL2可定義出多個開口OP’(或畫素區)。亦即,本實施例的這些第一訊號線SL1與這些第二訊號線SL2的複合結構可同時作為遮光圖案。也因此,第一訊號線SL1在方向Y上的寬度可定義出在方向Y上排列且相鄰的任兩開口OP’的間距S2’,且相鄰的兩條第一訊號線SL1之間的距離可定義出開口OP’在方向Y上的寬度W2’。相似地,第二訊號線SL2在方向X上的寬度可定義出在方向X上排列且相鄰的任兩開口OP’的間距S1’,且相鄰的兩條第二訊號線SL2之間的距離可定義出開口OP’在方向X上的寬度W1’。In detail, the plurality of first signal lines SL1 and the plurality of second signal lines SL2 of the transmissive
為了讓穿透式液晶元件110具有較高的開口率(aperture ratio),例如:這些開口OP’所占區域於基板111的垂直投影面積與透視區STR(如圖1及圖2所示)所占區域於基板111的垂直投影面積的百分比值大於95%,間距S1’與寬度W1’的比值及/或間距S2’與寬度W2’的比值可介於0.01至0.03之間,例如:間距S1’及/或間距S2’小於9微米,而寬度W1’及/或寬度W2’大於500微米。據此,可明顯降低這些畫素結構PX之間的非透光區(即訊號線所占區域)的可視性(visibility),有助於改善使用者在眼球訓練時與周圍環境的互動體驗,並提升視覺上的舒適度。In order for the transmissive
應可理解的是,在本實施例中,第一訊號線SL1與第二訊號線SL2可分別具有凸出部(未繪示),以遮擋主動元件T的半導體層在外界光源的長期照射下產生劣化,影響主動元件T的電性。It should be understood that, in this embodiment, the first signal line SL1 and the second signal line SL2 may respectively have protruding portions (not shown), so as to shield the semiconductor layer of the active element T from the long-term illumination of the external light source. Deterioration occurs, affecting the electrical properties of the active element T.
圖9是本發明的第三實施例的穿透式液晶元件的剖視示意圖。請參照圖9,本實施例的穿透式液晶元件110B與圖4的穿透式液晶元件110的差異在於:穿透式液晶元件110的四分之一波片的數量為兩個,分別為四分之一波片116與四分之一波片117。不同於第一實施例的穿透式液晶元件110,本實施例的穿透式液晶元件110B在偏光片POL1遠離液晶層LCL的一側還設有另一片四分之一波片117。據此,可增加穿透式液晶元件110B的製程彈性,並達到降低生產成本的目的。9 is a schematic cross-sectional view of a transmissive liquid crystal element according to a third embodiment of the present invention.

在本實施例中,穿透式液晶元件110C的畫素結構PX不具有如圖3的主動元件T,且圖3的第一訊號線SL1與第二訊號線SL2分別由第一條狀電極SE1與第二條狀電極SE2來取代。也就是說,穿透式液晶元件110C的多條第一條狀電極SE1沿著方向Y排列且在方向X上延伸,多條第二條狀電極SE2沿著方向X排列且在方向Y上延伸。值得注意的是,這些第一條狀電極SE1與這些第二條狀電極SE2的多個相交處(或重疊處)可定義出穿透式液晶元件110C的多個畫素區PA,而這些條狀電極重疊於這些畫素區PA的部分可形成對應這些畫素區PA的多組畫素電極。In this embodiment, the pixel structure PX of the transmissive
穿透式液晶元件110C的條狀電極例如是光穿透式電極,光穿透式電極的材質包括銦錫氧化物、銦鋅氧化物、鋁錫氧化物、鋁鋅氧化物、或其它合適的氧化物、極薄的金屬、奈米碳管、石墨烯或者是上述至少兩者之堆疊層。The strip electrodes of the transmissive
綜上所述,在本發明的一實施例的眼球訓練裝置中,可透視的穿透式液晶元件的遮光圖案的多個開口所占區域於基板的垂直投影面積與透視區所占區域於基板的垂直投影面積的百分比值大於95%。據此,可明顯降低多個畫素結構之間的非透光區的可視性,有助於改善使用者在眼球訓練時與周圍環境的互動體驗,並提升視覺上的舒適度。To sum up, in the eye training device of an embodiment of the present invention, the area occupied by the plurality of openings of the light-shielding pattern of the see-through transmissive liquid crystal element is in the vertical projection area of the substrate and the area occupied by the see-through area is in the substrate. The percentage value of the vertical projected area is greater than 95%. Accordingly, the visibility of the non-light-transmitting areas between the plurality of pixel structures can be significantly reduced, which helps to improve the user's interactive experience with the surrounding environment during eye training, and enhances visual comfort.
