參閱圖1與圖2,本新型顯示模組的一實施例,區分出一可視區VA及一非可視區NA。該顯示模組包含一顯示單元2、一遮光單元3、一抗反射單元4,及一接合單元5。其中,在本實施例中是以該非可視區NA形成於該可視區VA的側邊為例。然,要說明的是,該非可視區NA與該可視區VA的分布位置可依設計需求而有不同態樣,例如該非可視區NA可環繞於該可視區VA周圍,而不以本案圖式所顯示的態樣為限制。Referring to FIG. 1 and FIG. 2 , in an embodiment of the novel display module, a viewable area VA and a non-viewable area NA are distinguished. The display module includes a display unit 2 , a
該顯示單元2設置於該可視區VA,包括一顯示層21,及二個分別設置於該顯示層21相反二側的偏光層22,該顯示層21具有一可顯示畫面或出光的出光側211,其中一偏光層22是設置於該出光側211,而另一偏光層22是設置在該顯示層21相反於該出光側211的一側上。在本實施例中,該偏光層22為積層結構,是由吸附碘的聚乙烯醇(PVA)薄膜,及二分別設置於該聚乙烯醇薄膜相對兩側的三醋酸纖維層(TAC)所構成的碘系線偏光板。The display unit 2 is disposed in the visible area VA, and includes a display layer 21 and two polarizing
在本實施例中,是以該顯示單元2為液晶顯示器(見圖1),包括該顯示層21及二分別設置於該顯示層21的相對兩側的偏光層22為例,該顯示層21為積層結構,具有一液晶層,及分別設置於該液晶層的相對兩側邊的一彩色濾光層,及一具有薄膜電晶體的驅動層,且該出光側211位於該顯示層21鄰近該彩色濾光層的一側,令該二偏光層22分別設置於該彩色濾光層及該驅動層外側,且其吸收軸彼此夾90度。由於該液晶顯示器的其它細部結構為本技術領域所周知,因此,於此未再多加贅述。In this embodiment, the display unit 2 is a liquid crystal display (see FIG. 1 ), including the display layer 21 and two polarizing
在一些實施例中,該顯示單元2也可以是有機發光二極體顯示器(OLED)。此時,該顯示單元2的顯示層21為有機發光二極體結構,且僅需要於該顯示層21之出光側211配置於單一個偏光層22便可,而不以本實施例為限。In some embodiments, the display unit 2 may also be an organic light emitting diode display (OLED). At this time, the display layer 21 of the display unit 2 is an organic light emitting diode structure, and only a single polarizing
此外,該非可視區NA可以配置有驅動控制線路等其它可用以控制或啟動該顯示單元2的電子構件(圖未示),由於該等電子構件可視實際控制需求而有不同,且為本技術領域所周知,因此,於此也不再多加贅述。In addition, the non-visible area NA may be configured with other electronic components (not shown) such as driving control circuits that can be used to control or activate the display unit 2, because these electronic components may vary according to actual control requirements, and belong to the technical field. It is well known, therefore, it will not be repeated here.
該遮光單元3包括一至少設置於相鄰的該偏光層22上的線偏光膜31,及一設置於該線偏光膜31且位於該非可視區NA的遮光層32,且該線偏光膜31的吸收軸與該顯示單元2相鄰的該偏光層22的吸收軸間的夾角不大於45度。The
在本實施例中,該線偏光膜31為同時覆蓋該可視區VA及該非可視區NA,且會覆蓋該遮光層32。該線偏光膜31是與該偏光層22為相同的結構與材質,也是由一吸附碘的聚乙烯醇薄膜,及二分別設置於該聚乙烯醇薄膜兩側的三醋酸纖維層所構成的積層結構。該遮光層32則選自不透光的材質(例如:黑色油墨),令該顯示單元2僅可自該可視區VA的範圍對外顯示影像。In this embodiment, the linear polarizing
圖2說明設置於該出光側211之該偏光層22的吸收軸方向A1與該線偏光膜31的吸收軸方向A2的相對位置,以及吸收軸方向A1、A2的夾角I(即該線偏光膜31與相鄰的該偏光層22兩者的吸收軸的夾角)。詳細的說,該遮光單元3設置於該顯示單元2的出光側211,並藉由設置於該出光側211的該偏光層22與該遮光單元3的線偏光膜31兩者的吸收軸的夾角不大於45度,以確保該顯示單元2在啟動時,光線穿過相疊置的該線偏光膜31與該偏光層22的總穿透率不低於45%。較佳地,該線偏光膜31的吸收軸與該顯示單元2相鄰的該偏光層22的吸收軸的夾角(相當於圖2的夾角I)介於30度至45度,光線穿過相疊置的該線偏光膜31與該偏光層22的總穿透率介於45%至68%,可避免發生亮度不足的問題。2 illustrates the relative position of the absorption axis direction A1 of the polarizing
該抗反射單元4具有可透光性,並包括一設置在該遮光單元3反向於該顯示單元2一側的保護層41,及一設置在該保護層41上的抗反射層42。在本實施例中,該保護層41選自一玻璃蓋板,而該抗反射層42選自一表面塗佈有一抗眩硬化層(Anti glare-hard coating,AGHC)的對苯二甲酸乙二酯(PET)薄膜。該保護層41覆蓋於該線偏光膜31上,以避免該線偏光膜31毀損或自該顯示單元2脫落。該抗反射層42可減緩自該顯示單元2發出的光線發生內反射的情形,進而提高出光率,並提升該顯示模組所顯示影像的亮度、色度或對比值。The anti-reflection unit 4 has light transmittance, and includes a
詳細地說,由於自該顯示層21用於顯示出光的一面疊置了由具有不同折射率的材質所構成的該偏光層22、該線偏光膜31,以及該保護層41,而光線在通過不同材質的膜層界面時會發生不同程度的內反射與折射,而對該顯示單元2的顯示影像造成干擾(例如:色度、亮度或是對比值)。因此,本新型藉由設置該抗反射層42,使光線通過該抗反射層42,所造成的反射光對其他的反射光產生破壞性干涉,進而抵消不同膜層間反射光所造成的影響。In detail, since the polarizing
該接合單元5包括一用以黏接該顯示單元2與該遮光單元3的第一接合層51,及一用以黏接該遮光單元3與該抗反射單元4的第二接合層52。本實施例中,該第一接合層51選自液態光學膠(Liquid optical clear adhesive,LOCA),該第二接合層52選自感壓型黏著劑(Pressure sensitive adhesive,PSA)。The bonding unit 5 includes a
要說明的是,於一些實施例中,也可依需求僅設置該遮光單元3在該顯示單元2上,而無須設置該接合單元5及/或抗反射單元4。It should be noted that, in some embodiments, only the
茲將前述該顯示模組在未顯示影像時(即該顯示單元2未啟動時),進行色度值檢測,並將色度值檢測結果整理於表1。Herein, when the display module is not displaying an image (ie, when the display unit 2 is not activated), the chromaticity value detection is performed, and the chromaticity value detection results are arranged in Table 1.
在本實施例中,該色度值檢測是利用一分光式色差儀(Spectrophotometer,型號:CM700d,Konica Minolta)自該顯示模組靠近該遮光單元3的一面,並分別對應該可視區VA與該非可視區NA的位置進行量測,且在相同的位置分別以包含鏡面正反射光(Specular component include,SCI)模式,以及排除鏡面正反射光(Specular component exclude,SCE)模式兩種色度模式進行色度值檢測,而得到其色度值L、a、b。其中,色度值L代表亮度(數值越高,代表顏色越亮白);色度值a代表紅綠色度(數值越高,代表顏色越偏向紅色(+),數值越低,顏色越偏向綠色(-));色度值b代表黃藍色度(數值越高,代表顏色越偏向黃色(+),數值越低,顏色越偏向藍色(-))。In this embodiment, the chromaticity value is detected by using a spectrophotometer (Spectrophotometer, model: CM700d, Konica Minolta) from the display module close to the
接著,再將分別於該可視區VA與該非可視區NA所測得的色度值(L、a、b)依照公式:△E= 進行計算,而得到一△E值,該△E值表示該顯示模組在該可視區VA與該非可視區NA所呈現的顏色差異。 Then, according to the formula: △E= The calculation is performed to obtain a ΔE value, and the ΔE value represents the color difference presented by the display module in the visible area VA and the non-visible area NA.
表1
在本實施例中,該顯示模組透過該分光式色差儀是以兩種不同的色度模式(即包含鏡面正反射光模式,以及排除鏡面正反射光模式)進行色度值檢測,所測得該可視區VA與該非可視區NA的△E值皆不大於2,即可達到一體黑的視覺效果,而由表1可以得知,在該顯示單元2未啟動的情況下,兩個區域的顏色差異極小(兩種色度模式下所測得的△E值皆小於1),而不易由肉眼區分出該可視區VA與該非可視區NA,因此本實施例的顯示模組具有良好的一體黑的視覺效果。In this embodiment, the display module performs chromaticity value detection through the spectrophotometer in two different chromaticity modes (that is, the specular specular reflection mode is included, and the specular specular reflection mode is excluded). It is obtained that the ΔE values of the visible area VA and the non-visible area NA are both not greater than 2, and the visual effect of one black can be achieved, and it can be known from Table 1 that when the display unit 2 is not activated, the two areas are The color difference is very small (the ΔE values measured in the two chromaticity modes are all less than 1), and it is difficult to distinguish the visible area VA and the non-visual area NA by the naked eye, so the display module of this embodiment has a good One black visual effect.
綜上所述,藉由在該顯示單元2上設置該線偏光膜31,且該線偏光膜31的吸收軸與該顯示單元2相鄰的偏光層22的吸收軸的夾角不大於45度,而令該線偏光膜31與相鄰的該偏光層22在該顯示單元2啟動時的能維持良好的穿透率,且在該顯示單元2未啟動時,該可視區VA與該非可視區NA的顏色差異極小,而達到一體黑的視覺效果,故確實能達成本新型的目的。To sum up, by disposing the linear polarizing
