請參照圖1A和圖1B,顯示器100可包括用來組合成顯示裝置DD的多個顯示單元DU1、DU2、DU3、DU4和至少一光致變色結構PCS。在本實施例中,顯示器100可以是由多個顯示單元DU1~DU4所組合而成之拼接顯示裝置。應注意的是,本實施例的顯示裝置DD是由4個顯示單元DU1~DU4所組合而成(如圖1B所示),但本發明不以此為限。在其他實施例中,顯示裝置DD也可以是由其他數量的顯示單元所組合而成。另一方面,本實施例的顯示單元DU1~DU4是以矩形為例進行說明,但本發明不以此為限。在其他實施例中,顯示單元也可以是圓形、六邊型、八邊型或其他適合之形狀。Referring to FIG. 1A and FIG. 1B, the display 100 may include a plurality of display units DU1, DU2, DU3, DU4 and at least one photochromic structure PCS for combining into a display device DD. In this embodiment, the display 100 may be a mosaic display device composed of a plurality of display units DU1 to DU4. It should be noted that the display device DD of this embodiment is a combination of four display units DU1 to DU4 (as shown in FIG. 1B), but the present invention is not limited thereto. In other embodiments, the display device DD may be a combination of other numbers of display units. On the other hand, the display units DU1 to DU4 in this embodiment are described by taking a rectangle as an example, but the present invention is not limited thereto. In other embodiments, the display unit may be circular, hexagonal, octagonal, or other suitable shapes.
每一顯示單元DU1~DU4可包括相對設置的第一基板S1和第二基板S2以及設置於第一基板S1和第二基板S2之間的框膠SL1。在一些實施例中,可採用背光板、發光二極體(例如有機發光二極體或無機發光二極體)或其組合來作為顯示單元DU1~DU4的發光源。顯示單元DU1~DU4可為液晶顯示單元、發光二極體顯示單元或其他適合之顯示單元。在本實施例中,相鄰的兩個顯示單元DU1~DU4的光強度分別為I 1和I 2(如圖1A所示,相鄰的兩個顯示單元DU1、DU2所發出之光線L1、L2的光強度分別為I 1和I 2)。在本實施例中,第一基板S1可為主動陣列基板,而第二基板S2可為彩色濾光片基板,但本發明不以此為限。 Each of the display units DU1 to DU4 may include a first substrate S1 and a second substrate S2 opposite to each other, and a sealant SL1 disposed between the first substrate S1 and the second substrate S2. In some embodiments, a backlight, a light-emitting diode (such as an organic light-emitting diode or an inorganic light-emitting diode), or a combination thereof may be used as the light-emitting source of the display units DU1 to DU4. The display units DU1 to DU4 may be liquid crystal display units, light-emitting diode display units, or other suitable display units. In this embodiment, the light intensities of two adjacent display units DU1 to DU4 are respectively I 1 and I 2 (as shown in FIG. 1A, the light rays L1 and L2 emitted by the two adjacent display units DU1 and DU2 are The light intensities are I 1 and I 2 respectively. In this embodiment, the first substrate S1 may be an active array substrate, and the second substrate S2 may be a color filter substrate, but the present invention is not limited thereto.
在本實施例中,框膠SL1可設置於每個顯示單元DU1~DU4的邊界處,例如,框膠SL1可設置於每個顯示單元DU1~DU4的周圍。框膠SL1可為紫外光固化膠材、紅外光固化膠材、熱固化膠材或其組合,材料可為壓克力(acrylate),或環氧樹脂(epoxy resin)或壓克力環氧樹脂(acrylate epoxy resin),但不以此為限。在一些實施例中,顯示單元DU1~DU4可包括顯示介質層(未繪示)設置於由第一基板S1、第二基板S2和框膠SL1所界定之空間中。顯示介質層,例如可為液晶層,舉例來說,介質層可包括可被水平電場轉動或切換(in-plane-switching)的液晶分子或者是可被垂直電場轉動或切換(vertical switching)的液晶分子,但不限於此,亦可為有機發光二極體、無機發光二極體等其他適合之顯示介質。In this embodiment, the sealant SL1 may be disposed at the boundary of each display unit DU1 to DU4. For example, the sealant SL1 may be disposed around each display unit DU1 to DU4. The frame adhesive SL1 may be an ultraviolet curing adhesive, an infrared curing adhesive, a thermal curing adhesive, or a combination thereof. The material may be acrylate, epoxy resin, or acrylic epoxy resin. (acrylate epoxy resin), but not limited to this. In some embodiments, the display units DU1 to DU4 may include a display medium layer (not shown) disposed in a space defined by the first substrate S1, the second substrate S2, and the frame adhesive SL1. The display medium layer may be, for example, a liquid crystal layer. For example, the medium layer may include liquid crystal molecules that can be rotated or switched by a horizontal electric field or liquid crystals that can be rotated or switched by a vertical electric field. Molecules, but not limited thereto, may also be other suitable display media such as organic light emitting diodes, inorganic light emitting diodes, and the like.
請同時參照圖1A和圖1C,光致變色結構PCS可設置於各顯示單元DU1~DU4中的周圍框膠SL1與第二基板之間,因此,光致變色結構PCS係設置於各顯示單元DU1~DU4的周圍,換句話說,拼接顯示裝置DD中任兩相鄰的顯示單元DU1、DU2之間的交界處BD,且光致變色結構PCS的光穿透率T%與相鄰的兩個顯示單元DU1、DU2的光強度I 1、I 2的平均值成正比。也就是說,當相鄰的兩個顯示單元DU1、DU2的I 1、I 2的平均值越高時,光致變色結構PCS的光穿透率T%越高,越透光;當相鄰的兩個顯示單元DU1、DU2的I 1、I 2的平均值越低時,光致變色結構PCS的光穿透率T%越低,越不透光。光致變色結構PCS的光穿透率T%可藉由所吸收之光強度(I 1和I 2的平均值)發生變化,以降低拼接區(例如相鄰的兩個顯示單元DU1、DU2之間的交界處)和顯示區之間的亮度差異,如此可避免相鄰的兩個顯示單元DU1、DU2之間出現明顯的拼接縫,以改善整體畫面不連續的問題,使得使用者的觀看品質能夠提升。 Please refer to FIG. 1A and FIG. 1C at the same time. The photochromic structure PCS may be disposed between the surrounding frame SL1 and the second substrate in each display unit DU1 to DU4. Therefore, the photochromic structure PCS is disposed in each display unit DU1. Around DU4, in other words, the junction BD between any two adjacent display units DU1, DU2 in the mosaic display device DD, and the light transmittance T% of the photochromic structure PCS is similar to that of the adjacent two The average values of the light intensities I 1 and I 2 of the display units DU1 and DU2 are proportional to each other. That is, when the average value of I 1 and I 2 of the two adjacent display units DU1 and DU2 is higher, the light transmittance T% of the photochromic structure PCS is higher, and the light is more transparent. The lower the average value of I 1 and I 2 of the two display units DU1 and DU2 is, the lower the light transmittance T% of the photochromic structure PCS is, and the less opaque it is. The light transmittance T% of the photochromic structure PCS can be changed by the absorbed light intensity (the average value of I 1 and I 2 ) to reduce the splicing area (for example, the two adjacent display units DU1, DU2). And the brightness difference between the display boundary) and the display area, so that the obvious stitching seam between the two adjacent display units DU1, DU2 can be avoided, so as to improve the problem of discontinuity of the overall picture and make the user's viewing Quality can be improved.
另一方面,由於光致變色結構PCS的光穿透率會隨著所吸收之光強度變弱而降低,故即便在顯示器100未呈現畫面的狀態下(或呈現亮度較低的狀態下),任兩相鄰的顯示單元DU1~DU4之間仍不會出現明顯的拼接縫,並且觀看者也不易從拼接區看到顯示器100的內部構件。也就是說,顯示器100不管是在呈現畫面的狀態或是未呈現畫面的狀態,其整體畫面都具有良好的品質。舉例來說,光致變色結構PCS所吸收之光強度(I 1和I 2的平均值)大,則光致變色結構PCS呈現透明狀態;而當光致變色結構PCS所吸收之光強度(I 1和I 2的平均值)小,則光致變色結構PCS呈現深色狀態。 On the other hand, since the light transmittance of the photochromic structure PCS decreases as the intensity of the absorbed light becomes weaker, even in a state where the display 100 is not displaying a picture (or a state where the brightness is low), No obvious splicing seam will appear between any two adjacent display units DU1 to DU4, and it is not easy for a viewer to see the internal components of the display 100 from the splicing area. That is, whether the display 100 is in a state of presenting a picture or a state of not presenting a picture, the entire picture has good quality. For example, if the light intensity absorbed by the photochromic structure PCS (the average of I 1 and I 2 ) is large, the photochromic structure PCS appears transparent; and when the photochromic structure PCS absorbs the light intensity (I If the average value of 1 and I 2 ) is small, the photochromic structure PCS exhibits a dark state.
在一些實施例中,光致變色結構PCS可包括離子型染料化合物,例如由以下化學式1所表示的化合物。上述的離子型染料化合物在未照光(或光強度較弱)時帶有顏色,而經照光吸收可見光之後可引發聚合或交聯的自由基,使得光致變色結構PCS呈透明狀態或白色狀態。 [化學式1] In some embodiments, the photochromic structure PCS may include an ionic dye compound such as a compound represented by the following Chemical Formula 1. The above-mentioned ionic dye compounds have a color when not illuminated (or light intensity is weak), and after the visible light absorbs visible light, they can initiate polymerization or cross-linking free radicals, making the photochromic structure PCS in a transparent state or white state. [Chemical Formula 1]
在化學式1中,R1至R4可彼此相同或不同,且可各自獨立地選自烷基(alkyl)、芳基(aryl)、芳烷基(aralkyl)、烷芳基(alkaryl)、烯基(alkenyl)、炔基(alkynyl)、脂環基(alicyclic)、雜環基(heterocyclic)和烯丙基(allyl)所組成的族群中的任一者。In Chemical Formula 1, R1 to R4 may be the same as or different from each other, and may be each independently selected from an alkyl group, an aryl group, an aralkyl group, an alkaryl group, and an alkenyl group ( Any one of the groups consisting of alkenyl, alkynyl, alicyclic, heterocyclic, and allyl.
在化學式1中,D可選自次甲基(methine)、聚次甲基(polymethine)、三芳基甲烷(triarylmethane)、吲哚啉(indoline)、噻嗪(thiazine)、呫噸(xanthene)、噁嗪(oxazine)、吖嗪(azine)、花青(cyanine)、羰花青(carbocyanine)、半花青染料(hemicyanine)、若丹明(rhodamine)和氮雜次甲基(azamethine)所組成的族群中的任一者。In Chemical Formula 1, D may be selected from the group consisting of methine, polymethine, triarylmethane, indoline, thiazine, xanthene, Composed of oxazine, azine, cyanine, carbocyanine, hemicyanine, rhodamine and azamethine Any of the ethnic groups.
在化學式1中,B可選自呫噸(xanthene)和氧雜菁(oxonol)所組成的族群中的任一者。In Chemical Formula 1, B may be selected from any one of the group consisting of xanthene and oxonol.
此外,如圖1B所示,光致變色結構PCS可設置在各顯示單元DU1~DU4的周圍。也就是說,光致變色結構PCS於第一基板S1上的垂直投影可大致相似於框膠SL1於第一基板S1上的垂直投影,但本發明不以此為限。圖2為本發明另一實施例的顯示器的俯視示意圖。如圖2所示,顯示器100可選擇性地包括設置在顯示裝置DD周圍的遮光材料SM,如此光致變色結構PCS可選擇性地僅設置在任兩相鄰的顯示單元DU1~DU4之間。遮光材料SM可以是不透光材料,例如適用於黑色矩陣(black matrix)的材料。In addition, as shown in FIG. 1B, the photochromic structure PCS may be disposed around each of the display units DU1 to DU4. That is, the vertical projection of the photochromic structure PCS on the first substrate S1 may be substantially similar to the vertical projection of the sealant SL1 on the first substrate S1, but the invention is not limited thereto. FIG. 2 is a schematic top view of a display according to another embodiment of the present invention. As shown in FIG. 2, the display 100 may optionally include a light-shielding material SM disposed around the display device DD, such that the photochromic structure PCS may be selectively disposed only between any two adjacent display units DU1 to DU4. The light-shielding material SM may be an opaque material, such as a material suitable for a black matrix.
請參考圖3。圖3為本發明又一實施例的顯示器的局部剖面示意圖。如圖3所示,在一些實施例中,光致變色結構PCS可為複數個且彼此相互分離,並排地配置於各顯示單元的周圍,當相鄰的兩個顯示單元的光強度不同時,由於光致變色結構PCS的光穿透率T%可藉由所吸收之光強度發生變化,因此,光致變色結構PCS的光穿透率隨著遠離相鄰的兩個顯示單元DU1~DU4之間的交界處而呈現漸變式變化。如此一來,每個光致變色結構PCS的光穿透率都可藉由所吸收之光強度(I 1和I 2的平均值)進行調整,更能降低拼接區(例如相鄰的兩個顯示單元DU1~DU4之間的交界處)和顯示區之間的亮度差異,使得整體畫面的連續性更佳,進一步提升使用者的觀看品質。 Please refer to Figure 3. FIG. 3 is a schematic partial cross-sectional view of a display according to another embodiment of the present invention. As shown in FIG. 3, in some embodiments, the photochromic structures PCS may be plural and separated from each other, and are arranged side by side around each display unit. When the light intensities of two adjacent display units are different, Since the light transmittance T% of the photochromic structure PCS can be changed by the absorbed light intensity, the light transmittance of the photochromic structure PCS varies with the distance from two adjacent display units DU1 to DU4. The interface between them is gradually changing. In this way, the light transmittance of each photochromic structure PCS can be adjusted by the absorbed light intensity (the average of I 1 and I 2 ), which can further reduce the splicing area (such as two adjacent The difference in brightness between the display units DU1 to DU4) and the display area makes the overall picture continuity better and further improves the viewing quality of the user.
請參考圖4A至圖4C。圖4A至圖4C分別為本發明又一實施例的顯示器的俯視示意圖。光致變色結構PCS除了可以局部或是環繞顯示單元外,光致變色結構PCS亦可以分離設置,在一些實施例中,上述相互分離之多個光致變色結構PCS的排列方式可呈矩陣排列(如圖4A所示),但本發明不以此為限。在另一些實施例中,上述相互分離之多個光致變色結構PCS的排列方式也可呈錯位設置(如圖4B和圖4C所示)。另外,本發明並未限定光致變色結構PCS的形狀或數量。舉例來說,光致變色結構PCS可為矩形(如圖4A和圖4B所示)或六邊形(如圖4C所示)。Please refer to FIGS. 4A to 4C. 4A to 4C are schematic top views of a display according to another embodiment of the present invention. In addition to the photochromic structure PCS, the photochromic structure PCS can be arranged separately or in addition to the display unit. In some embodiments, the above-mentioned separated photochromic structures PCS can be arranged in a matrix ( (As shown in FIG. 4A), but the present invention is not limited thereto. In other embodiments, the arrangement of the plurality of photochromic structures PCS separated from each other may also be arranged in an offset manner (as shown in FIGS. 4B and 4C). In addition, the present invention does not limit the shape or number of the photochromic structure PCS. For example, the photochromic structure PCS may be rectangular (as shown in FIG. 4A and FIG. 4B) or hexagonal (as shown in FIG. 4C).
請繼續參照圖1A和圖1C和圖5,圖5為本發明再一實施例的顯示器的剖面示意圖。光致變色結構PCS可設置在顯示單元DU1~DU4內(in-cell),例如將光致變色結構PCS設置於各個顯示單元DU1~DU4中的框膠SL1和第二基板S2之間,但本發明不以此為限。在另一些實施例中,光致變色結構PCS可設置在顯示單元DU1~DU4上(on-cell),例如將光致變色結構PCS設置於顯示單元DU1~DU4的交界處上(如圖5所示)。Please continue to refer to FIGS. 1A and 1C and FIG. 5, which is a schematic cross-sectional view of a display according to another embodiment of the present invention. The photochromic structure PCS may be disposed in the display units DU1 to DU4 (for example, the photochromic structure PCS is disposed between the frame rubber SL1 and the second substrate S2 in each display unit DU1 to DU4, but this The invention is not limited to this. In other embodiments, the photochromic structure PCS may be disposed on the display units DU1 to DU4 (for example, the photochromic structure PCS is disposed at the junction of the display units DU1 to DU4 (as shown in FIG. 5). Show).
圖6為本發明又再一實施例的顯示器的剖面示意圖,其中顯示器200大致相同於顯示器100,其不同之處在於顯示器200的框膠SL2作為光致變色結構,故相同或相似元件使用相同或相似標號,其餘構件之連接關係、材料及其製程已於前文中進行詳盡地描述,故於下文中不再重複贅述。6 is a schematic cross-sectional view of a display according to yet another embodiment of the present invention. The display 200 is substantially the same as the display 100. The difference is that the sealant SL2 of the display 200 is used as a photochromic structure. Therefore, the same or similar components use the same or Similar reference numerals, connection relationships, materials, and processes of the remaining components have been described in detail in the foregoing, so they will not be repeated hereafter.
在一些實施例中,如圖6所示,顯示器200的框膠SL2可作為光致變色結構,亦即採用或含有與光致變色結構PCS相同的光致變色材料,使得框膠SL2的光穿透率與I 1和I 2的平均值成正比。如此一來,在框膠SL2的厚度大於如圖1A所示之光致變色結構PCS的情況下,更能夠進一步降低拼接區(例如任兩相鄰的顯示單元DU1~DU4之間的交界處)和顯示區之間的亮度差異,使得整體畫面的連續性更佳。 In some embodiments, as shown in FIG. 6, the sealant SL2 of the display 200 can be used as a photochromic structure, that is, the same photochromic material as that of the photochromic structure PCS is adopted or contained, so that the light of the sealant SL2 passes through The transmittance is directly proportional to the average of I 1 and I 2 . In this way, when the thickness of the frame adhesive SL2 is larger than the photochromic structure PCS shown in FIG. 1A, the splicing area can be further reduced (for example, the junction between any two adjacent display units DU1 to DU4) The brightness difference between the display area and the display area makes the overall picture continuity better.
在一些實施例中,顯示器200可選擇性地包括設置在框膠SL2和第一基板S1之間的反射層RL。如此一來,在光線能夠經由反射層RL反射至出光面的情況下,拼接區和顯示區之間的亮度差異能夠進一步降低,使得整體畫面的連續性更佳。在一些實施例中,反射層RL的材料可包括能夠反射可見光的材料,例如鋁(Al)、銀(Ag)、鉻(Cr)、銅(Cu)、鎳(Ni)、鈦(Ti)、鉬(Mo)、鎂(Mg)、鉑(Pt)、金(Au)或其組合。In some embodiments, the display 200 may optionally include a reflective layer RL disposed between the sealant SL2 and the first substrate S1. In this way, when light can be reflected to the light emitting surface through the reflective layer RL, the brightness difference between the splicing area and the display area can be further reduced, so that the continuity of the overall picture is better. In some embodiments, the material of the reflective layer RL may include a material capable of reflecting visible light, such as aluminum (Al), silver (Ag), chromium (Cr), copper (Cu), nickel (Ni), titanium (Ti), Molybdenum (Mo), magnesium (Mg), platinum (Pt), gold (Au), or a combination thereof.
綜上所述,在上述實施例的顯示器中,在光致變色結構設置於相鄰的兩個顯示單元之間的交界處,且光致變色結構的光穿透率與I 1和I 2的平均值成正比的情況下,光致變色結構的光穿透率可藉由所吸收之光強度(I 1和I 2的平均值)進行調整,以降低拼接區(例如相鄰的兩個顯示單元之間的交界處)和顯示區之間的亮度差異,避免相鄰的兩個顯示單元之間出現明顯的拼接縫,以改善整體畫面不連續的問題,使得使用者的觀看品質能夠提升。 In summary, in the display of the above embodiment, the photochromic structure is disposed at the boundary between two adjacent display units, and the light transmittance of the photochromic structure is the same as that of I 1 and I 2 . When the average value is proportional, the light transmittance of the photochromic structure can be adjusted by the absorbed light intensity (the average value of I 1 and I 2 ) to reduce the splicing area (such as two adjacent displays) The brightness difference between the junction between the units) and the display area, to avoid the obvious splicing seam between two adjacent display units, to improve the problem of discontinuity in the overall picture, so that the viewing quality of the user can be improved .
