Description
本發明的實施例係有關於一種用於立體影像顯示裝置的對準標記以及一種用於利用該等對準標記之立體影像顯示裝置的對準方法與系統。Embodiments of the present invention relate to an alignment mark for a stereoscopic image display device and an alignment method and system for a stereoscopic image display device using the alignment marks.
立體影像顯示裝置係利用立體技術或自動立體技術來顯示3D影像。此立體技術憑著介於左、右眼之間的視差、以及可用或可不用特殊眼鏡,以得到3D效果。當利用特殊眼鏡時,由於直接射出型顯示裝置或投影機以特殊眼鏡的極化方向改變或以一分時方式來顯示出左右影像,觀看者透過極化眼鏡或快門眼鏡觀看3D影像。以不為眼鏡之光學零件,例如,一視差屏障(parallax barrier)或雙凸鏡片(lenticular lens)設置在顯示螢幕的前方或後方,藉以將左影像與右影像的光軸予以離析出來。The stereoscopic image display device displays a 3D image using a stereoscopic technique or an autostereoscopic technique. This stereoscopic technique relies on parallax between the left and right eyes, and with or without special glasses to achieve a 3D effect. When special glasses are used, since the direct-injection type display device or the projector changes the polarization direction of the special glasses or displays the left and right images in a minute-sharing manner, the viewer views the 3D images through the polarized glasses or the shutter glasses. Optical components that are not glasses, for example, a parallax barrier or a lenticular lens are disposed in front of or behind the display screen to isolate the optical axes of the left and right images.
在採用極化眼鏡的3D影像實施中,一極化分離元件(polarization separation element),例如,一圖案相位差膜(retarder)必須附接於顯示面板上。而該圖案相位差膜使得顯示在顯示面板的左眼影像與右眼影像的極化互為不相同。當利用極化眼鏡來觀看顯示於立體影像顯示裝置的3D影像時,觀看者透過極化眼鏡的左眼濾光片感受到左眼影像極化光,並透過極化眼鏡的右眼濾光片感受到右眼影像極化光,藉此,感受出3D效果。In a 3D image implementation employing polarized glasses, a polarization separation element, for example, a pattern retarder, must be attached to the display panel. The pattern retardation film makes the polarizations of the left eye image and the right eye image displayed on the display panel different from each other. When the polarized glasses are used to view the 3D image displayed on the stereoscopic image display device, the viewer perceives the left-eye image polarized light through the left-eye filter of the polarized glasses and transmits the right-eye filter of the polarized glasses. Feel the polarized light of the right eye image, and then feel the 3D effect.
然而,不藉由利用極化分離元件,快門眼鏡型立體影像顯示裝置將顯示面板上的左眼影像與右眼影像分別交替地顯示出,並同步於左眼影像與右眼影像,且將快門眼鏡的左快門與右快門分別交替地予以開啟。觀看者透過左快門可看到左眼影像,並透過右快門可看到右眼影像,藉此感受到3D效果。僅管不需要任何極化分離元件,快門眼鏡型立體影像顯示裝置受限於由於昂貴快門眼鏡所生的高價格。以3D影像品質觀點而言,快門眼鏡型立體影像顯示裝置係處於劣勢,實因左眼影像與右眼影像受到以預設的時間區間的分時所支配,相較於極化眼鏡型顯示裝置,快門眼鏡型立體影像顯示裝置將會增加閃爍(flicker)以及3D干擾(crosstalk)問題,因此,將導致觀看疲勞感增加。該”閃爍”係指顯示在顯示面板上的影像的亮度在一固定時間區間波動。該”3D干擾”係指觀看者在同一時間以單一眼睛(左眼或右眼)感受到顯示在顯示面板上的左眼影像與右眼影像,以致於使用者感受到影像部分重疊。However, without using the polarization separation element, the shutter glasses type stereoscopic image display device alternately displays the left eye image and the right eye image on the display panel, and synchronizes the left eye image with the right eye image, and the shutter The left and right shutters of the glasses are alternately opened. The viewer can see the left eye image through the left shutter and the right eye image through the right shutter to feel the 3D effect. The shutter glasses type stereoscopic image display device is limited by the high price due to expensive shutter glasses, although it does not require any polarization separation elements. From the viewpoint of 3D image quality, the shutter glasses type stereoscopic image display device is in a disadvantage, because the left eye image and the right eye image are subject to the time division of the preset time interval, compared to the polarized glasses type display device. The shutter glasses type stereoscopic image display device will increase the flicker and 3D crosstalk problems, and thus, the viewing fatigue will increase. The "flicker" means that the brightness of the image displayed on the display panel fluctuates within a fixed time interval. The “3D interference” means that the viewer perceives the left eye image and the right eye image displayed on the display panel with a single eye (left eye or right eye) at the same time, so that the user feels that the image partially overlaps.
於快門眼鏡型立體顯示裝置,左快門與右快門的每一個必須同步於顯示面板而電力開啟/關閉。為達此目的,快門眼鏡包含同步電路,用於將左快門與右快門開啟與關閉。該同步電路包含紅外線接收電路、驅動電壓切換電路、或相同類似等。據此,快門眼鏡型立體影像顯示裝置需要高價的快門眼鏡。快門眼鏡會產生電磁輻射。In the shutter glasses type stereoscopic display device, each of the left shutter and the right shutter must be synchronized with the display panel to turn on/off the power. To this end, the shutter glasses contain a synchronization circuit for turning the left and right shutters on and off. The synchronizing circuit includes an infrared receiving circuit, a driving voltage switching circuit, or the like. Accordingly, the shutter glass type stereoscopic image display device requires expensive shutter glasses. The shutter glasses produce electromagnetic radiation.
相較於快門眼鏡型立體影像顯示裝置,因為利用低價的極化眼鏡,該極化眼鏡型立體影像顯示裝置能享有低價,僅管需要附接於顯示面板的極化分離元件。在極化眼鏡型立體影像顯示裝置中,左眼影像與右眼影像係同時顯示在顯示面板上,並分開成每行方式,以致於相較於藉由快門眼鏡型顯示裝置來感受3D影像,將為較低程度的閃爍與3D干擾,如此,能降低觀看者所感受到的疲勞感。Compared with the shutter glasses type stereoscopic image display device, the polarized glasses type stereoscopic image display device can enjoy low price by using low-cost polarized glasses, and only needs to be attached to the polarization separation element of the display panel. In the polarized glasses type stereoscopic image display device, the left eye image and the right eye image are simultaneously displayed on the display panel and are separated into each line so that the 3D image is perceived by the shutter glass type display device. It will be a lower degree of flicker and 3D interference, thus reducing the fatigue felt by the viewer.
圖案相位差膜可分類為眼鏡圖案相位差膜GPRs(glass pattern retarders)與薄膜圖案相位差膜FPRs,在眼鏡圖案相位差膜GPRs中,一圖案相位差膜形成在玻璃基板上,而在薄膜圖案相位差膜FPRs中,一圖案相位差膜形成在薄膜基板上。相較於眼鏡圖案相位差膜,薄膜圖案相位差膜具有優勢,因為具有降低顯示面板的厚度、重量與價格的能力。因此,薄膜圖案相位差膜的研發正持續不斷地進行。The pattern retardation film can be classified into a glass pattern retardation film (GPRs) and a film pattern retardation film FPRs. In the eyeglass pattern retardation film GPRs, a pattern retardation film is formed on the glass substrate, and the film pattern is formed on the glass substrate. In the retardation film FPRs, a pattern retardation film is formed on the film substrate. The thin film pattern retardation film is advantageous in comparison with the glasses pattern retardation film because of its ability to reduce the thickness, weight, and price of the display panel. Therefore, the development of the thin film pattern retardation film is continuously carried out.
在極化眼鏡型立體影像顯示裝置中,介於圖案相位差膜與顯示面板之間的對準精確度,於價格、生產率、以及3D影像品質上,具有相當大的影響作用。依據一種對準圖案相位差膜與顯示面板的習知方法,如第1圖所示,對準標記AM1’至AM4’形成在顯示面板PNL上,而對準標記AM1至AM4則形成在圖案相位差膜PR上,並且顯示面板PNL附接於圖案相位差膜PR上,同時顯示面板PNL與圖案相位差膜PR互相對準,以致沿著一垂直方向對準標記AM1至AM4與對準標記AM1’至AM4’會合。In the polarized glasses type stereoscopic image display device, the alignment accuracy between the pattern retardation film and the display panel has a considerable influence on the price, the productivity, and the 3D image quality. According to a conventional method of aligning a pattern retardation film and a display panel, as shown in FIG. 1, alignment marks AM1' to AM4' are formed on the display panel PNL, and alignment marks AM1 to AM4 are formed in the pattern phase. On the differential film PR, and the display panel PNL is attached to the pattern retardation film PR, while the display panel PNL and the pattern retardation film PR are aligned with each other, so that the marks AM1 to AM4 and the alignment mark AM1 are aligned along a vertical direction. 'To AM4' will meet.
需要一各別程序來製造圖案相位差膜PR,以在圖案相位差膜PR上形成對準標記AM1至AM4。A separate program is required to fabricate the pattern retardation film PR to form alignment marks AM1 to AM4 on the pattern retardation film PR.
當圖案相位差膜PR的基板(或薄膜)保持固定時,對準標記AM1至AM4必須形成,而圖案相位差膜PR的製造程序不能連續地予以實施,如此,將導致程序時間的延遲。When the substrate (or film) of the pattern retardation film PR is kept fixed, the alignment marks AM1 to AM4 must be formed, and the manufacturing process of the pattern retardation film PR cannot be continuously performed, and thus, the delay of the program time is caused.
為了將左眼影像與右眼影像之極化特性予以區分,圖案與對準標記AM1至AM4一起形成在圖案相位差膜PR上,並相對於顯示面板PNL的像素。介於圖案相位差膜PR圖案與對準標記AM1至AM4之間會發生未對準的情況。於此種情況之下,即使當圖案相位差膜PR的對準標記AM1至AM4由於介於對準標記AM1至AM4以及圖案相位差膜PR圖案之間的對準誤差而與顯示面板PNL的對準標記AM1’至AM4’精準對準,在圖案相位差膜PR的圖案與顯示面板PNL的像素之間產生的對準誤差將結束。In order to distinguish the polarization characteristics of the left-eye image from the right-eye image, the pattern is formed on the pattern phase difference film PR together with the alignment marks AM1 to AM4 with respect to the pixels of the display panel PNL. A misalignment may occur between the pattern phase difference film PR pattern and the alignment marks AM1 to AM4. In this case, even when the alignment marks AM1 to AM4 of the pattern phase difference film PR are aligned with the display panel PNL due to the alignment error between the alignment marks AM1 to AM4 and the pattern retardation film PR pattern The alignment marks AM1' to AM4' are precisely aligned, and an alignment error generated between the pattern of the pattern phase difference film PR and the pixels of the display panel PNL will end.

現在參考本發明的具體實施例,並參考所附圖式作出詳細說明。無論如何,相似的附圖標記在這裏用於代表相同或相似的組成部分。需要注意的是,如果確定現有技術的描述可導致誤解本發明,將省略對現有技術的詳細描述。Reference will now be made in detail to the particular embodiments embodiments In any event, similar reference numbers are used herein to represent the same or similar components. It is to be noted that a detailed description of the prior art will be omitted if it is determined that the description of the prior art may lead to misunderstanding of the present invention.
第2圖為概要說明依據一實施例之立體影像顯示裝置的示意圖。FIG. 2 is a schematic view schematically showing a stereoscopic image display device according to an embodiment.
參照第2圖,依據一實施例的立體影像顯示裝置包括顯示面板PNL、薄膜圖案相位差膜FPR、以及極化眼鏡PGLS。Referring to FIG. 2, a stereoscopic image display device according to an embodiment includes a display panel PNL, a thin film pattern retardation film FPR, and polarized glasses PGLS.
顯示面板PNL可實際為平面顯示裝置的顯示面板,而該平面顯示裝置例如可為場發射顯示器FED(field emission display)、電漿顯示面板PDP、有機發光二極體OLED、或電泳顯示EPD器。The display panel PNL may be actually a display panel of a flat display device, and the flat display device may be, for example, a field emission display (FED), a plasma display panel PDP, an organic light emitting diode OLED, or an electrophoretic display EPD.
在一2D模式中,顯示面板PNL在像素陣列上顯示出2D影像視訊資料。在一3D模式中,顯示面板PNL在像素陣列中的每行上分隔出互相的左眼影像與右眼影像,並同時顯示出該左眼影像與該右眼影像。In a 2D mode, the display panel PNL displays 2D videovisual data on the pixel array. In a 3D mode, the display panel PNL separates each other's left eye image and right eye image on each line in the pixel array, and simultaneously displays the left eye image and the right eye image.
薄膜圖案相位差膜FPR附接至顯示面板PNL上。在薄膜圖案相位差膜FPR中,第一極化選擇圖案PR1的光軸垂直於第二極化選擇圖案PR2的光軸。在薄膜圖案相位差膜FPR中,第一極化選擇圖案PR1與第二極化選擇圖案PR2交替安置。第一極化選擇圖案PR1延遲顯示在顯示面板PNL之奇數線的左眼影像(或右眼影像)的光線,並傳送第一極化光的光線。第二極化選擇圖案PR2延遲顯示在顯示面板PNL之偶數線的右眼影像(或左眼影像)的光線,並將傳送第二極化光的光線。第一極化光為圓極化(circularly polarized)光或線性極化(linearly polarized)光,而第二極化光為圓極化光或線性極化光,第二極化光的光軸係垂直於第一極化光的光軸。The thin film pattern retardation film FPR is attached to the display panel PNL. In the thin film pattern phase difference film FPR, the optical axis of the first polarization selection pattern PR1 is perpendicular to the optical axis of the second polarization selection pattern PR2. In the thin film pattern phase difference film FPR, the first polarization selection pattern PR1 and the second polarization selection pattern PR2 are alternately disposed. The first polarization selection pattern PR1 delays the light of the left-eye image (or the right-eye image) displayed on the odd-numbered lines of the display panel PNL, and transmits the light of the first polarized light. The second polarization selection pattern PR2 delays the light of the right eye image (or the left eye image) displayed on the even line of the display panel PNL, and transmits the light of the second polarized light. The first polarized light is circularly polarized light or linearly polarized light, and the second polarized light is circularly polarized light or linearly polarized light, and the optical axis of the second polarized light It is perpendicular to the optical axis of the first polarized light.
極化眼鏡PGLS包含左眼濾光片與右眼濾光片。左眼濾光片具有與薄膜圖案相位差膜FPR之第一極化選擇圖案PR1的光軸為相同的光軸。右眼濾光片具有與薄膜圖案相位差膜FPR之第二極化選擇圖案PR2的光軸為相同的光軸。因此,觀看者透過極化眼鏡PGLS的左眼濾光片僅看到顯示在左眼影像的像素,並且透過極化眼鏡PGLS的右眼濾光片僅看到顯示在右眼影像的像素,致使產生雙眼視差(binocular parallax),因而,使得觀看者感受到3D效果。The polarized glasses PGLS include a left eye filter and a right eye filter. The left-eye filter has the same optical axis as the optical axis of the first polarization selection pattern PR1 of the thin film pattern phase difference film FPR. The right eye filter has the same optical axis as the optical axis of the second polarization selection pattern PR2 of the thin film pattern phase difference film FPR. Therefore, the viewer sees only the pixels displayed in the left-eye image through the left-eye filter of the polarized glasses PGLS, and the right-eye filter that passes through the polarized glasses PGLS sees only the pixels displayed in the right-eye image, resulting in A binocular parallax is generated, thus making the viewer feel the 3D effect.
第3圖為說明依據一實施例之對準立體影像顯示裝置的方法。FIG. 3 is a diagram illustrating a method of aligning a stereoscopic image display device in accordance with an embodiment.
依據於第3圖所說明的方法,不具有對準標記的薄膜圖案相位差膜FPR將以對準標記AK1至AK6與顯示面板PNL對準。多個對準標記可被稱為對準記號(align marking)。According to the method illustrated in Fig. 3, the thin film pattern phase difference film FPR having no alignment mark will be aligned with the display panel PNL with the alignment marks AK1 to AK6. Multiple alignment marks can be referred to as align markings.
如第4圖所示,薄膜圖案相位差膜FPR包含第一極化選擇圖案PR1與第二極化選擇圖案PR2,用於互相分開左眼影像的極化光(亦可視為“左眼影像極化光”),以及分開右眼影像的極化光(亦可視為“右眼影像極化光”)。第一極化選擇圖案PR1與第二極化選擇圖案PR2面對顯示面板PNL的像素陣列。顯示面板PNL的像素陣列包含具有顯示2D或3D影像之像素的顯示區域。As shown in FIG. 4, the thin film pattern retardation film FPR includes a first polarization selection pattern PR1 and a second polarization selection pattern PR2 for separating polarized light of the left eye image from each other (also referred to as "left eye image pole". Light," and polarized light that separates the image of the right eye (also known as "right-lens image polarized light"). The first polarization selection pattern PR1 and the second polarization selection pattern PR2 face the pixel array of the display panel PNL. The pixel array of the display panel PNL includes a display area having pixels that display 2D or 3D images.
第一極化選擇圖案PR1與第二極化選擇圖案PR2互相具有不同的光軸,藉由一預設相位值而延遲入射光的相位,並傳送相位延遲的光線作為極化光,極化光的光軸為互相垂直,因此,使得左眼影像與右眼影像在極化特性上互相不同。舉例言之,第一極化選擇圖案PR1具有第一光軸,並面對顯示面板PNL之像素陣列的奇數線,以將來自奇數線之線性極化光的相位延遲1/4波長,並傳送顯示在奇數線作為第一極化光的左眼(或右眼)光線。第二極化選擇圖案PR2具有垂直於第一光軸的第二光軸,並面對顯示面板PNL之像素陣列的偶數線,以將來自偶數線之線性極化光的相位延遲1/4波長,並傳送顯示在偶數線作為第二極化光的右眼(或左眼)光線。The first polarization selection pattern PR1 and the second polarization selection pattern PR2 have different optical axes from each other, delay the phase of the incident light by a predetermined phase value, and transmit the phase delayed light as polarized light, polarized light. The optical axes are perpendicular to each other, so that the left-eye image and the right-eye image are different in polarization characteristics. For example, the first polarization selection pattern PR1 has a first optical axis and faces an odd line of the pixel array of the display panel PNL to delay the phase of the linearly polarized light from the odd line by 1/4 wavelength and transmit The left eye (or right eye) light that is displayed on the odd line as the first polarized light. The second polarization selection pattern PR2 has a second optical axis perpendicular to the first optical axis and faces an even line of the pixel array of the display panel PNL to delay the phase of the linearly polarized light from the even line by 1/4 wavelength And transmits the right eye (or left eye) light that is displayed on the even line as the second polarized light.
依據本發明的一實施例,當顯示面板PNL之像素陣列中的線數量為N(N是一偶數)時,藉由加上第一極化選擇圖案PR1與第二極化選擇圖案PR2二者,於薄膜圖案相位差膜FPR的線數量可為N。依據本發明的一實施例,第一極化選擇圖案PR1或第二極化選擇圖案PR2的數量是N/2。According to an embodiment of the invention, when the number of lines in the pixel array of the display panel PNL is N (N is an even number), by adding both the first polarization selection pattern PR1 and the second polarization selection pattern PR2 The number of lines of the film pattern retardation film FPR may be N. According to an embodiment of the invention, the number of the first polarization selection pattern PR1 or the second polarization selection pattern PR2 is N/2.
依據本發明的另一實施例,當顯示面板PNL之像素陣列的線數量為N時,藉由加上第一極化選擇圖案PR1與第二極化選擇圖案PR2二者,於薄膜圖案FPR的線數可為N+1。於此情況,第一極化選擇圖案PR1與第二極化選擇圖案PR2的數量,其一可為N/2,而另一則為N/2+1。舉例而言,第一極化選擇圖案PR1的數量為N/2加上1,而第二極化選擇圖案PR2的數量則為N/2。可選地,第二極化選擇圖案PR2的數量為N/2加上1,而第一極化選擇圖案PR1的數量則為N/2。According to another embodiment of the present invention, when the number of lines of the pixel array of the display panel PNL is N, by adding both the first polarization selection pattern PR1 and the second polarization selection pattern PR2 to the thin film pattern FPR The number of lines can be N+1. In this case, the number of the first polarization selection pattern PR1 and the second polarization selection pattern PR2 may be N/2 and the other is N/2+1. For example, the number of first polarization selection patterns PR1 is N/2 plus 1, and the number of second polarization selection patterns PR2 is N/2. Alternatively, the number of second polarization selection patterns PR2 is N/2 plus 1, and the number of first polarization selection patterns PR1 is N/2.
薄膜圖案相位差膜FPR進一步包含上面多餘區域以及下面多餘區域。薄膜圖案相位差膜FPR的該上面多餘區域與該下面多餘區域至少之一包含多餘圖案DUM1與DUM2。當將薄膜圖案相位差膜FPR與顯示面板PNL對準時,多餘圖案DUM1與DUM2作為參考圖案,用於識別薄膜圖案相位差膜FPR2的上面多餘區域與下面多餘區域。多餘圖案DUM1與DUM2面對顯示面板PNL之像素陣列區域以外的非顯示區域。因而,多餘圖案DUM1與DUM2不會面對像素陣列中的像素。The thin film pattern retardation film FPR further includes an excess area on the upper surface and an excess area below. At least one of the upper unnecessary area and the lower excess area of the thin film pattern phase difference film FPR includes the excess patterns DUM1 and DUM2. When the thin film pattern phase difference film FPR is aligned with the display panel PNL, the excess patterns DUM1 and DUM2 serve as reference patterns for identifying the upper unnecessary area and the lower excess area of the thin film pattern phase difference film FPR2. The redundant patterns DUM1 and DUM2 face non-display areas other than the pixel array area of the display panel PNL. Thus, the redundant patterns DUM1 and DUM2 do not face the pixels in the pixel array.
多餘圖案DUM1與DUM2分別形成在薄膜圖案相位差膜FPR的上面多餘區域與下面多餘區域。多餘圖案DUM1與DUM2的每一個具有相同於第一極化選擇圖案PR1與第二極化選擇圖案PR2的每一個的寬度的寬度,或具有不同於第一極化選擇圖案PR1與第二極化選擇圖案PR2的每一個的寬度的寬度,藉以能輕易區別相對於顯示面板之像素陣列區域的第一極化選擇圖案PR1與第二極化選擇圖案PR2。The excess patterns DUM1 and DUM2 are formed on the upper unnecessary area and the lower excess area of the thin film pattern phase difference film FPR, respectively. Each of the redundant patterns DUM1 and DUM2 has the same width as the width of each of the first polarization selection pattern PR1 and the second polarization selection pattern PR2, or has a different polarization from the first polarization selection pattern PR1 and the second polarization. The width of the width of each of the patterns PR2 is selected so that the first polarization selection pattern PR1 and the second polarization selection pattern PR2 with respect to the pixel array region of the display panel can be easily distinguished.
第4圖為說明多餘圖案DUM1與DUM2的寬度大於極化選擇圖案PR1與PR2的寬度的一實施例。然而,本發明的該等實施例並非僅限於此。舉例而言,多餘圖案DUM1與DUM2的每一個可具有一個或多個圖案,而所具有的每一個圖案具有相同於第一極化選擇圖案PR1與第二極化選擇圖案PR2的寬度的寬度。依據本發明的一實施例,多餘圖案DUM1與DUM2分別具有大於如第4圖所示之第一極化選擇圖案PR1與第二極化選擇圖案PR2的每一個的寬度的寬度A與A’。可選地,多餘圖案DUM1與DUM2分別具有小於第一極化選擇圖案PR1與第二極化選擇圖案PR2的每一個的寬度的寬度A與A’。第一多餘圖案DUM1形成在薄膜圖案相位差膜FPR的上面多餘區域,並具有相同於第一極化選擇圖案PR1與第二極化選擇圖案PR2其中之一的極化特性,而第二多餘圖案DUM2形成在薄膜圖案相位差膜FPR的下面多餘區域,並具有相同於第一極化選擇圖案PR1與第二極化選擇圖案PR2其中之一的極化特性。Fig. 4 is a view showing an embodiment in which the widths of the excess patterns DUM1 and DUM2 are larger than the widths of the polarization selection patterns PR1 and PR2. However, the embodiments of the invention are not limited thereto. For example, each of the redundant patterns DUM1 and DUM2 may have one or more patterns, and each of the patterns has a width that is the same as the width of the first polarization selection pattern PR1 and the second polarization selection pattern PR2. According to an embodiment of the present invention, the excess patterns DUM1 and DUM2 respectively have widths A and A' greater than the width of each of the first polarization selection pattern PR1 and the second polarization selection pattern PR2 as shown in FIG. Alternatively, the excess patterns DUM1 and DUM2 respectively have widths A and A' smaller than the width of each of the first polarization selection pattern PR1 and the second polarization selection pattern PR2. The first unnecessary pattern DUM1 is formed on the upper unnecessary region of the thin film pattern phase difference film FPR, and has polarization characteristics identical to one of the first polarization selection pattern PR1 and the second polarization selection pattern PR2, and the second plurality The remaining pattern DUM2 is formed in the excess area below the thin film pattern phase difference film FPR, and has polarization characteristics identical to one of the first polarization selection pattern PR1 and the second polarization selection pattern PR2.
多餘圖案DUM1與DUM2並非藉由與用於製造極化選擇圖案PR1與PR2的製造程序分開的製造程序來形成。然,多餘圖案DUM1與DUM2藉由如同於極化選擇圖案PR1與PR2的製造方法的方法與極化選擇圖案PR1與PR2一起形成。因此,依據本發明的該等實施例,藉由檢查薄膜圖案相位差膜FPR的多餘圖案DUM1與DUM2,可輕易識別出極化選擇圖案PR1與PR2之對準偏移的程度。The excess patterns DUM1 and DUM2 are not formed by a manufacturing process separate from the manufacturing process for fabricating the polarization selection patterns PR1 and PR2. However, the excess patterns DUM1 and DUM2 are formed together with the polarization selection patterns PR1 and PR2 by a method similar to the method of manufacturing the polarization selection patterns PR1 and PR2. Therefore, according to the embodiments of the present invention, the degree of misalignment of the polarization selection patterns PR1 and PR2 can be easily recognized by inspecting the excess patterns DUM1 and DUM2 of the thin film pattern retardation film FPR.
為易於區別出薄膜圖案相位差膜FPR的上面多餘區域與下面多餘區域,第一多餘圖案DUM1的極化特性可相同於或不同於第二多餘圖案DUM1的極化特性。因此,本發明的一實施例可認出介於多餘圖案DUM1、DUM2以及極化選擇圖案PR1、PR2之間的極化及/或寬度的差異,以識別出多餘圖案DUM1、DUM2與極化選擇圖案PR1、PR2的不同。In order to easily distinguish the upper unnecessary region and the lower redundant region of the thin film pattern phase difference film FPR, the polarization characteristics of the first redundant pattern DUM1 may be the same as or different from the polarization characteristics of the second redundant pattern DUM1. Therefore, an embodiment of the present invention recognizes the difference in polarization and/or width between the redundant patterns DUM1, DUM2 and the polarization selection patterns PR1, PR2 to identify the excess patterns DUM1, DUM2 and polarization selection. The difference between the patterns PR1 and PR2.
依據本發明的一實施例,為了易於區別薄膜圖案相位差膜FPR的上面多餘區域與下面多餘區域,形成在圖案相位差膜FPR上端的第一多餘圖案DUM1的寬度A可設為不同於形成在圖案相位差膜FPR下端的第二多餘圖案DUM2的寬度A’。舉例言之,第一多餘圖案DUM1的寬度A可大於或小於第二多餘圖案DUM2的寬度A’。因此,藉由確認出介於多餘圖案DUM1、DUM2與極化選擇圖案PR1、PR2之間的極化及/或寬度的不同,多餘圖案DUM1、DUM2與極化選擇圖案PR1、PR2可予以區別出來。According to an embodiment of the present invention, in order to easily distinguish the upper unnecessary region and the lower redundant region of the thin film pattern retardation film FPR, the width A of the first redundant pattern DUM1 formed at the upper end of the pattern retardation film FPR may be set to be different from the formation. The width A' of the second redundant pattern DUM2 at the lower end of the pattern retardation film FPR. For example, the width A of the first redundant pattern DUM1 may be larger or smaller than the width A' of the second redundant pattern DUM2. Therefore, the excess patterns DUM1, DUM2 and the polarization selection patterns PR1, PR2 can be distinguished by confirming the difference in polarization and/or width between the excess patterns DUM1, DUM2 and the polarization selection patterns PR1, PR2. .
在薄膜圖案相位差膜FPR中,介於多餘圖案DUM1或DUM2與參考線CTL之間的距離預設為用於設計薄膜圖案相位差膜FPR的因素。因此,藉由識別出多餘圖案DUM1與DUM2的位置,可得知位於離開多餘圖案DUM1與DUM2一預設距離的參考線CTL的位置。當薄膜圖案相位差膜FPR與顯示面板PNL對準時,參考線CTL為介於在薄膜圖案相位差膜FPR之中央的第一極化選擇圖案PR1與第二極化選擇圖案PR2與位於在顯示面板PNL之中央的對準標記AK2、AK5之間的分界線。薄膜圖案相位差膜FPR的參考線CTL並非藉由與極化選擇圖案PR1與PR2的製造程序分開的另一程序來形成,而是與極化選擇圖案PR1與PR2一起形成。In the thin film pattern retardation film FPR, the distance between the excess pattern DUM1 or DUM2 and the reference line CTL is preset as a factor for designing the thin film pattern retardation film FPR. Therefore, by recognizing the positions of the redundant patterns DUM1 and DUM2, the position of the reference line CTL located at a predetermined distance from the excess patterns DUM1 and DUM2 can be known. When the thin film pattern retardation film FPR is aligned with the display panel PNL, the reference line CTL is the first polarization selection pattern PR1 and the second polarization selection pattern PR2 located in the center of the thin film pattern phase difference film FPR and is located on the display panel The boundary between the alignment marks AK2 and AK5 at the center of the PNL. The reference line CTL of the thin film pattern phase difference film FPR is not formed by another procedure separate from the manufacturing process of the polarization selection patterns PR1 and PR2, but is formed together with the polarization selection patterns PR1 and PR2.
當薄膜圖案相位差膜FPR與顯示面板PNL對準時,薄膜圖案相位差膜FPR的參考線CTL對準於顯示面板PNL的對準標記AK1至AK6。因而,無須在薄膜圖案相位差膜FPR形成分隔對準標記。When the thin film pattern phase difference film FPR is aligned with the display panel PNL, the reference line CTL of the thin film pattern phase difference film FPR is aligned with the alignment marks AK1 to AK6 of the display panel PNL. Therefore, it is not necessary to form the separation alignment mark in the thin film pattern retardation film FPR.

As shown in FIGS. 6A and 6B, in the case where the alignment patterns 51, 52 or 53, 54 are provided at intervals of 10 μm, when the thin film pattern phase difference film FPR is aligned with the display panel PNL, the alignment error may be It is known to be every 10 μm.

The width (or thickness) of the left side alignment pattern 61 is the distance from the panel reference line CTL_PNL to the uppermost end of the allowable alignment error range AMR.

右側對準圖案62包含一單一圖案,該單一圖案的水平軸係偏移自左側對準圖案61的水平軸。右側對準圖案62的寬度(或厚度)係為自面板參考線CTL_PNL到容許對準誤差範圍AMR最下端的距離。舉例言之,右側對準圖案62的寬度為距面板參考線CTL_PNL-30μm。The right alignment pattern 62 includes a single pattern whose horizontal axis is offset from the horizontal axis of the left alignment pattern 61. The width (or thickness) of the right side alignment pattern 62 is the distance from the panel reference line CTL_PNL to the lowermost end of the allowable alignment error range AMR. For example, the width of the right side alignment pattern 62 is 30 μm from the panel reference line CTL_PNL.
第五對準圖案AK5的圖案係垂直對稱於第二對準標記Ak2的圖案。第五對準圖案AK5包含左側對準圖案64、以及右側對準圖案63。The pattern of the fifth alignment pattern AK5 is vertically symmetrical to the pattern of the second alignment mark Ak2. The fifth alignment pattern AK5 includes a left side alignment pattern 64 and a right side alignment pattern 63.
左側對準圖案64包含一單一圖案。左側對準圖案64的寬度(或厚度)係為自面板參考線CTL_PNL到容許對準誤差範圍AMR最下端的距離。舉例言之,左側對準圖案64的寬度為距面板參考線CTL_PNL-30μm。The left alignment pattern 64 includes a single pattern. The width (or thickness) of the left side alignment pattern 64 is the distance from the panel reference line CTL_PNL to the lowermost end of the allowable alignment error range AMR. For example, the width of the left side alignment pattern 64 is 30 μm from the panel reference line CTL_PNL.
右側對準圖案63包含一單一圖案,該單一圖案的水平軸係偏移自左側對準圖案64的水平軸。右側對準圖案63的寬度(或厚度)係為自面板參考線CTL_PNL到容許對準誤差範圍AMR最上端的距離。舉例言之,右側對準圖案63的寬度為距面板參考線CTL_PNL+30μm。The right side alignment pattern 63 includes a single pattern whose horizontal axis is offset from the horizontal axis of the left side alignment pattern 64. The width (or thickness) of the right alignment pattern 63 is the distance from the panel reference line CTL_PNL to the uppermost end of the allowable alignment error range AMR. For example, the width of the right side alignment pattern 63 is 30 μm from the panel reference line CTL_PNL.
如第10A圖與第10B圖所示,當面板參考線CTL_PNL會合薄膜圖案相位差膜FPR的參考線CTL時,顯示面板PNL與薄膜圖案相位差膜FPR理想地對準。如第7A與第7B圖所示,當左側對準圖案61、64、以及右側對準圖案62、63的每一個係形成為一單一圖案時,於左側對準標記AK1至AK3、以及右側對準標記AK4至AK6的每一個可直覺並易於確定是否有一對準錯誤介於薄膜圖案相位差膜FPR與顯示面板PNL之間。舉例而言,當薄膜圖案相位差膜FPR的參考線CTL自任一個第二對準標記Ak2的左側對準圖案61、第五對準標記AK5的左側對準圖案64、以及第二對準標記Ak2的右側對準圖案62、第五對準標記AK5的右側對準圖案63偏離時,可確定的是薄膜圖案相位差膜FPR與顯示面板PNL並未良好對準。反之,當薄膜圖案相位差膜FPR的參考線CTL並未自任一個第二對準標記Ak2的左側對準圖案61、第五對準標記AK5的左側對準圖案64、以及第二對準標記Ak2的右側對準圖案62、第五對準標記AK5的右側對準圖案63偏離時,可確定的是薄膜圖案相位差膜FPR與顯示面板PNL良好對準。As shown in FIGS. 10A and 10B, when the panel reference line CTL_PNL meets the reference line CTL of the thin film pattern phase difference film FPR, the display panel PNL is ideally aligned with the thin film pattern phase difference film FPR. As shown in FIGS. 7A and 7B, when each of the left side alignment patterns 61, 64 and the right side alignment patterns 62, 63 is formed as a single pattern, the left alignment marks AK1 to AK3, and the right side are aligned. Each of the alignment marks AK4 to AK6 can be intuitively and easily determined whether or not an alignment error is between the thin film pattern phase difference film FPR and the display panel PNL. For example, when the reference line CTL of the thin film pattern phase difference film FPR is from the left side alignment pattern 61 of any one of the second alignment marks Ak2, the left side alignment pattern 64 of the fifth alignment mark AK5, and the second alignment mark Ak2 When the right alignment pattern 62 and the right alignment pattern 63 of the fifth alignment mark AK5 are deviated, it can be determined that the thin film pattern retardation film FPR is not well aligned with the display panel PNL. On the contrary, when the reference line CTL of the thin film pattern phase difference film FPR is not from the left side alignment pattern 61 of the second alignment mark Ak2, the left side alignment pattern 64 of the fifth alignment mark AK5, and the second alignment mark Ak2 When the right alignment pattern 62 and the right alignment pattern 63 of the fifth alignment mark AK5 are deviated, it can be determined that the thin film pattern retardation film FPR is well aligned with the display panel PNL.
依據本發明的一實施例,多餘圖案DUM1與DUM2其中之一的位置被確定,而薄膜圖案相位差膜FPR的參考線CTL的位置係取決於離多餘圖案DUM1、DUM2的距離,該距離為介於多餘圖案DUM1、DUM2與薄膜圖案相位差膜FPR的參考線CTL之間的距離。依據本發明的一實施例,薄膜圖案相位差膜FPR的參考線CTL係與形成在顯示面板PNL的中央部分之二個對立側的第二對準圖案AK2、第五對準圖案AK5對準,藉此,使薄膜圖案相位差膜FPR與顯示面板PNL對準。According to an embodiment of the present invention, the position of one of the redundant patterns DUM1 and DUM2 is determined, and the position of the reference line CTL of the thin film pattern phase difference film FPR depends on the distance from the redundant patterns DUM1, DUM2, which is The distance between the redundant patterns DUM1, DUM2 and the reference line CTL of the thin film pattern phase difference film FPR. According to an embodiment of the present invention, the reference line CTL of the thin film pattern phase difference film FPR is aligned with the second alignment pattern AK2 and the fifth alignment pattern AK5 formed on the opposite sides of the central portion of the display panel PNL. Thereby, the thin film pattern retardation film FPR is aligned with the display panel PNL.
依據本發明的一實施例,薄膜圖案相位差膜FPR的多餘圖案DUM1與DUM2係作為用於評估薄膜圖案相位差膜FPR之參考線所需的參考圖案。因此,無須將位在顯示面板PNL的最上與最下周圍部分的對準標記AK1、AK3、AK4、以及AK6與薄膜圖案相位差膜FPR的多餘圖案DUM1、DUM2正確地對準。依據本發明的一實施例,在安置薄膜圖案相位差膜FPR的參考線CTL及/或顯示面板PNL時,使得薄膜圖案相位差膜FPR的參考線CTL位在第二對準標記AK2與第五對準標記AK5的中央,而薄膜圖案相位差膜FPR與顯示面板PNL對準,並互相連接在一起。According to an embodiment of the present invention, the excess patterns DUM1 and DUM2 of the thin film pattern phase difference film FPR are used as reference patterns required for evaluating the reference line of the thin film pattern phase difference film FPR. Therefore, it is not necessary to correctly align the alignment marks AK1, AK3, AK4, and AK6 positioned at the uppermost and lowermost peripheral portions of the display panel PNL with the excess patterns DUM1, DUM2 of the thin film pattern phase difference film FPR. According to an embodiment of the present invention, when the reference line CTL and/or the display panel PNL of the thin film pattern phase difference film FPR are disposed, the reference line CTL of the thin film pattern phase difference film FPR is positioned at the second alignment mark AK2 and the fifth The center of the mark AK5 is aligned, and the film pattern retardation film FPR is aligned with the display panel PNL and connected to each other.

參照第10A圖與第10B圖,對準標記AK1至AK6的每一個形成在顯示面板PNL之不具有任何黑色矩陣的遮光屏區域中。依據本發明的一實施例,基於介於薄膜圖案相位差膜FPR之參考線CTL與形成在顯示面板PNL之記號的距離差異,可直覺正確地得知介於薄膜圖案相位差膜FPR與顯示面板PNL之間未對準的程度。Referring to FIGS. 10A and 10B, each of the alignment marks AK1 to AK6 is formed in a region of the display panel PNL which does not have any black matrix. According to an embodiment of the present invention, based on the difference in the distance between the reference line CTL of the thin film pattern retardation film FPR and the mark formed on the display panel PNL, the film pattern retardation film FPR and the display panel can be intuitively and accurately known. The degree of misalignment between PNLs.
如第10A圖與第10B圖所示,當薄膜圖案相位差膜FPR與顯示面板PNL對準時,若薄膜圖案相位差膜FPR的參考線CTL與顯示面板PNL的左側對準圖案61、64重疊,而參考線CTL與顯示面板PNL的右側對準圖案62、63重疊,對準誤差係在容許對準誤差範圍AMR內,而對準情況因而可確定為良好。當薄膜圖案相位差膜FPR與顯示面板PNL對準時,薄膜圖案相位差膜FPR的參考線CTL與顯示面板PNL的對準標記AK1至AK6經由影像系統而被顯示在控制電腦的監視器上。如第10A圖與第10B圖所示,當薄膜圖案相位差膜FPR的參考線CTL與顯示面板PNL的左側對準圖案61、64重疊,而參考線CTL與顯示面板PNL的右側對準圖案62、63重疊時,在對準標記AK2與AK5的圖案61至64中,看不到薄膜圖案相位差膜FPR的參考線CTL。As shown in FIGS. 10A and 10B, when the thin film pattern phase difference film FPR is aligned with the display panel PNL, if the reference line CTL of the thin film pattern phase difference film FPR overlaps with the left side alignment patterns 61, 64 of the display panel PNL, While the reference line CTL overlaps with the right side alignment patterns 62, 63 of the display panel PNL, the alignment error is within the allowable alignment error range AMR, and the alignment can thus be determined to be good. When the thin film pattern phase difference film FPR is aligned with the display panel PNL, the alignment marks CTL of the thin film pattern phase difference film FPR and the alignment marks AK1 to AK6 of the display panel PNL are displayed on the monitor of the control computer via the image system. As shown in FIGS. 10A and 10B, when the reference line CTL of the thin film pattern phase difference film FPR overlaps with the left side alignment patterns 61, 64 of the display panel PNL, and the reference line CTL and the right side alignment pattern 62 of the display panel PNL are as shown. When 63 is overlapped, the reference line CTL of the thin film pattern phase difference film FPR is not seen in the patterns 61 to 64 of the alignment marks AK2 and AK5.
如第11A圖與第11B圖所示,當薄膜圖案相位差膜FPR的參考線CTL既不與左側對準圖案61、64重疊也不與右側對準圖案62、63重疊時,可確定對準情況是不好的。As shown in FIGS. 11A and 11B, when the reference line CTL of the thin film pattern phase difference film FPR is neither overlapped with the left side alignment patterns 61, 64 nor overlapped with the right side alignment patterns 62, 63, alignment can be determined. The situation is not good.
第12A圖與第12B圖為說明依據一實施例之立體影像顯示裝置的對準系統的示意圖。參照第12A圖至第14圖,依據一實施例的對準系統包含第一對準臺ST1、第一影像系統VR1至VR4、第二對準臺ST2、第二影像系統VP1至VP4、鼓DR、以及控制電腦CTRL。12A and 12B are schematic views illustrating an alignment system of a stereoscopic image display device according to an embodiment. Referring to FIGS. 12A through 14, an alignment system according to an embodiment includes a first alignment stage ST1, first image systems VR1 to VR4, a second alignment stage ST2, second image systems VP1 to VP4, and a drum DR. And control the computer CTRL.
第一對準臺ST1吸起並抓住薄膜圖案相位差膜FPR。第一對準臺ST1連接至一xy自動機器(xy robot)。如第13圖所示,在控制電腦CTRL的控制下,該xy自動機器於X軸與Y軸方向移動第一對準臺ST1。在控制電腦CTRL的控制下,第一對準臺ST1可於θ軸方向轉動。因此,如第13圖所示,在控制電腦CTRL的控制下,第一對準臺ST1於X軸、Y軸、及θ軸方向可最終調整薄膜圖案相位差膜FPR,以控制薄膜圖案相位差膜FPR的對準情況。The first alignment stage ST1 sucks up and grasps the thin film pattern retardation film FPR. The first alignment stage ST1 is connected to an xy robot. As shown in Fig. 13, the xy automatic machine moves the first alignment stage ST1 in the X-axis and Y-axis directions under the control of the control computer CTRL. Under the control of the control computer CTRL, the first alignment stage ST1 is rotatable in the θ-axis direction. Therefore, as shown in FIG. 13, under the control of the control computer CTRL, the first alignment stage ST1 can finally adjust the film pattern retardation film FPR in the X-axis, Y-axis, and θ-axis directions to control the film pattern phase difference. Alignment of the film FPR.
如第13圖所示,第一影像系統VR1至VR4包含第一影像模組VR1至第四影像模組VR4。第一影像模組VR1與第二影像模組VR2捕捉薄膜圖案相位差膜FPR的第二多餘圖案DUM2或第一多餘圖案DUM1的二相對側的影像,並將所捕捉的影像傳送到控制電腦CTRL。第三影像模組VR3與第四影像模組VR4捕捉位於薄膜圖案相位差膜FPR之中央的參考線CTL之二相對側的影像,以及捕捉鄰接於參考線CTL之第一極化選擇圖案PR1與第二極化選擇圖案PR2的二相對側的影像,並將所捕捉到的影像傳送到控制電腦CTRL。因此,第一影像系統VR1至VR4捕捉固定在第一對準臺ST1上之薄膜圖案相位差膜FPR的四邊緣,並將所捕捉到的影像傳送到控制電腦CTRL。As shown in FIG. 13, the first image systems VR1 to VR4 include the first image module VR1 to the fourth image module VR4. The first image module VR1 and the second image module VR2 capture the image of the second redundant pattern DUM2 of the thin film pattern retardation film FPR or the opposite side of the first redundant pattern DUM1, and transmit the captured image to the control. Computer CTRL. The third image module VR3 and the fourth image module VR4 capture images on opposite sides of the reference line CTL located at the center of the thin film pattern retardation film FPR, and capture the first polarization selection pattern PR1 adjacent to the reference line CTL. The second polarization selects images on opposite sides of the pattern PR2 and transmits the captured images to the control computer CTRL. Therefore, the first image systems VR1 to VR4 capture the four edges of the thin film pattern phase difference film FPR fixed on the first alignment stage ST1, and transfer the captured images to the control computer CTRL.
第二對準臺ST2吸起並抓住顯示面板PNL。第二對準臺ST2連接至一xy自動機器。如第14圖所示,在控制電腦CTRL的控制下,該xy自動機器於X軸與Y軸方向移動第二對準臺ST2。在控制電腦CTRL的控制下,第二對準臺ST2可於θ軸方向轉動。因而,如第14圖所示,在控制電腦CTRL的控制下,第二對準臺ST2於X軸、Y軸、及θ軸方向可最終調整顯示面板PNL,以控制顯示面板PNL的對準情況。The second alignment stage ST2 sucks up and grasps the display panel PNL. The second alignment stage ST2 is connected to an xy automatic machine. As shown in Fig. 14, the xy automatic machine moves the second alignment stage ST2 in the X-axis and Y-axis directions under the control of the control computer CTRL. Under the control of the control computer CTRL, the second alignment stage ST2 is rotatable in the θ-axis direction. Therefore, as shown in FIG. 14, under the control of the control computer CTRL, the second alignment stage ST2 can finally adjust the display panel PNL in the X-axis, Y-axis, and θ-axis directions to control the alignment of the display panel PNL. .
如第14圖所示,第二影像系統VP1至VP4包含第一影像模組VP1至第四影像模組VP4。第一影像模組VP1與第二影像模組VP2捕捉形成在顯示面板PNL的上端之二相對側的對準標記AK1與AK4的影像,或形成在顯示面板PNL的下端之二相對側的對準標記AK3與AK6的影像,並將所捕捉的影像傳送到控制電腦CTRL。第三影像模組VP3與第四影像模組VP4補捉形成在顯示面板PNL的中央之二相對側的對準標記AK2與AK5的影像,並將所補捉的影像傳送到控制電腦CTRL。因此,第二影像系統VP1與VP4將形成在顯示面板PNL上之四個對準標記的影像經由第二對準臺ST2傳送至控制電腦CTRL。As shown in FIG. 14, the second image systems VP1 to VP4 include the first image module VP1 to the fourth image module VP4. The first image module VP1 and the second image module VP2 capture images of the alignment marks AK1 and AK4 formed on opposite sides of the upper end of the display panel PNL, or are aligned on opposite sides of the lower end of the display panel PNL. Mark the images of AK3 and AK6 and transfer the captured images to the control computer CTRL. The third image module VP3 and the fourth image module VP4 capture images of the alignment marks AK2 and AK5 formed on opposite sides of the center of the display panel PNL, and transmit the captured images to the control computer CTRL. Therefore, the second image systems VP1 and VP4 transmit the images of the four alignment marks formed on the display panel PNL to the control computer CTRL via the second alignment stage ST2.
在第一對準臺ST1與第二對準臺ST2之間提供鼓DR。鼓DR藉由在控制電腦的控制下的一電動機而轉動,並藉由在上下(z軸方向)方向的一線性導引裝置(linear guide means)予以移動。當位於第一對準臺ST1上的薄膜圖案相位差膜FPR與位於第二對準臺ST2上的顯示面板PNL良好對準之後,在於控制電腦CTL的控制之下,鼓DR接收來自第一對準臺ST1的薄膜圖案相位差膜FPR,並將薄膜圖案相位差膜FPR附接至密封在第二對準臺ST2上的顯示面板上。鼓DR包含具有少量黏性的黏著層或黏著薄膜,致使薄膜圖案相位差膜FPR穩固地附著於鼓DR上。A drum DR is provided between the first alignment stage ST1 and the second alignment stage ST2. The drum DR is rotated by an electric motor under the control of the control computer, and is moved by a linear guide means in the up and down (z-axis direction) direction. After the thin film pattern phase difference film FPR located on the first alignment stage ST1 is well aligned with the display panel PNL located on the second alignment stage ST2, under the control of the control computer CTL, the drum DR receives from the first pair The thin film pattern retardation film FPR of the alignment ST1 is attached to the display panel sealed on the second alignment stage ST2 with the thin film pattern retardation film FPR. The drum DR contains an adhesive layer or an adhesive film having a small amount of adhesiveness, so that the film pattern retardation film FPR is firmly attached to the drum DR.
控制電腦CTRL依據預先設置的程式控制對準系統之所有元件的操作,並控制介於顯示面板PNL與薄膜圖案相位差膜FPR之間的對準的整個過程。介於多餘圖案DUM1、DUM2與薄膜圖案相位差膜FPR的參考線CTL之間的距離可預存在控制電腦CTRL中。The control computer CTRL controls the operation of all the components of the alignment system in accordance with a preset program, and controls the entire process of alignment between the display panel PNL and the film pattern retardation film FPR. The distance between the redundant patterns DUM1, DUM2 and the reference line CTL of the thin film pattern phase difference film FPR can be pre-stored in the control computer CTRL.
基於接收自第一影像系統VR1至VR4的第一影像模組VR1與第二影像模組VR2的影像,控制電腦CTRL識別出多餘圖案DUM1與DUM2。控制電腦CTRL從多餘圖案DUM1與DUM2的位置計算薄膜圖案相位差膜FPR的參考線CTL的位置,並基於計算結果啟動第一對準臺ST1,藉以將薄膜圖案相位差膜FPR的參考線CTL移動至所需的位置。Based on the images of the first image module VR1 and the second image module VR2 received from the first image systems VR1 to VR4, the control computer CTRL recognizes the excess patterns DUM1 and DUM2. The control computer CTRL calculates the position of the reference line CTL of the thin film pattern phase difference film FPR from the positions of the redundant patterns DUM1 and DUM2, and activates the first alignment stage ST1 based on the calculation result, thereby moving the reference line CTL of the thin film pattern phase difference film FPR To the desired location.
隨之,控制電腦CTRL將比對由第一影像系統VR1至VR4以及第二影像系統VP1至VP4所獲得的影像。藉由比對所接收到的影像,控制電腦CTRL確定出介於薄膜圖案相位差膜FPR與顯示面板PNL之間的對準誤差。當對準誤差超出容許對準誤差範圍AMR時,控制電腦CTRL啟動第一對準臺ST1與第二對準臺ST2或xy自動機器,用以調整薄膜圖案相位差膜FPR及/或顯示面板PNL,直至顯示面板PNL的對準標記AK2與AK5的面板參考線CTL_PNL與薄膜圖案相位差膜FPR的參考線CTL係位於容許對準誤差範圍AMR內。Accordingly, the control computer CTRL will compare the images obtained by the first image systems VR1 to VR4 and the second image systems VP1 to VP4. By comparing the received images, the control computer CTRL determines an alignment error between the thin film pattern phase difference film FPR and the display panel PNL. When the alignment error exceeds the allowable alignment error range AMR, the control computer CTRL activates the first alignment stage ST1 and the second alignment stage ST2 or xy automatic machine for adjusting the thin film pattern retardation film FPR and/or the display panel PNL Until the alignment marks AK2 of the display panel PNL and the panel reference line CTL_PNL of the AK5 and the reference line CTL of the thin film pattern phase difference film FPR are within the allowable alignment error range AMR.
顯示出由第一影像系統所獲得的第二對準標記AK2和第五對準標記AK5之面板參考線CTL_PNL與薄膜圖案相位差膜FPR之參考線CTL的一虛擬中央線係顯示在控制電腦CTRL的監視器上。A virtual center line showing the second alignment mark AK2 and the fifth alignment mark AK5 of the panel reference line CTL_PNL obtained by the first image system and the reference line CTL of the thin film pattern phase difference film FPR is displayed on the control computer CTRL On the monitor.
控制電腦CTRL可控制第二對準臺ST2,以調整顯示面板PNL的位置,致使虛擬中央線與面板參考線CTL_PNL能予以會合。再者,控制電腦CTRL可調整薄膜圖案相位差膜FPR的位置,直至與面板參考線CTL_PNL會合的虛擬中央線,以及薄膜圖案相位差膜FPR的參考線CTL係位於容許對準誤差範圍AMR內。The control computer CTRL can control the second alignment stage ST2 to adjust the position of the display panel PNL so that the virtual center line and the panel reference line CTL_PNL can be combined. Furthermore, the control computer CTRL can adjust the position of the thin film pattern retardation film FPR until the virtual center line that meets the panel reference line CTL_PNL, and the reference line CTL of the thin film pattern phase difference film FPR are within the allowable alignment error range AMR.
如第8A圖、第8B圖、第10A圖與第10B圖所示,當理想地互相調整薄膜圖案相位差膜FPR與顯示面板PNL,或對準誤差係在容許對準誤差範圍AMR內,啟動鼓DR,藉以將薄膜圖案相位差膜FPR朝顯示面板PNL移動,致使薄膜圖案相位差膜FP與R顯示面板PNL連接。As shown in FIG. 8A, FIG. 8B, FIG. 10A and FIG. 10B, when the thin film pattern phase difference film FPR and the display panel PNL are ideally adjusted to each other, or the alignment error is within the allowable alignment error range AMR, the activation is started. The drum DR moves the thin film pattern retardation film FPR toward the display panel PNL, so that the thin film pattern retardation film FP is connected to the R display panel PNL.
依據本發明的一實施例,對準系統進一步包含一脫落(peel-off)裝置,該脫落裝置脫掉薄膜圖案相位差膜FPR的脫模薄膜(release film),以曝露薄膜圖案相位差膜FPR的黏著層。當薄膜圖案相位差膜FPR與顯示面板PNL對準時,藉由基於顯示面板PNL控制薄膜圖案相位差膜FPR的位置,對準系統可調整介於薄膜圖案相位差膜FPR與顯示面板PNL之間的對準情況。因而,第二校準定位臺ST2用的y軸與θ軸校準(calibration)功能可以省略,而鼓DR可以實施,以僅在上下方向(z軸方向)移動。According to an embodiment of the invention, the alignment system further includes a peel-off device that removes the release film of the thin film pattern retardation film FPR to expose the thin film pattern retardation film FPR Adhesive layer. When the thin film pattern retardation film FPR is aligned with the display panel PNL, the alignment system can adjust between the thin film pattern retardation film FPR and the display panel PNL by controlling the position of the thin film pattern retardation film FPR based on the display panel PNL. Align the situation. Therefore, the y-axis and θ-axis calibration functions for the second calibration positioning stage ST2 can be omitted, and the drum DR can be implemented to move only in the up-and-down direction (z-axis direction).
一種對準顯示面板PNL與薄膜圖案相位差膜FPR的方法將相繼敘述於下。A method of aligning the display panel PNL with the thin film pattern retardation film FPR will be described successively below.
如第12A圖所示,在將薄膜圖案相位差膜FPR固定在第一對準臺ST1上之後,控制電腦CTRL透過第一影像系統VR1至VR4識別出薄膜圖案相位差膜FPR的對準情況。控制電腦CTRL解析由第一影像系統VR1至VR4所補捉之用於多餘圖案DUM1與DUM2的影像之一,藉以確定出多餘圖案DUM1與DUM2的位置。As shown in FIG. 12A, after the thin film pattern retardation film FPR is fixed on the first alignment stage ST1, the control computer CTRL recognizes the alignment of the thin film pattern phase difference film FPR through the first image systems VR1 to VR4. The control computer CTRL parses one of the images for the redundant patterns DUM1 and DUM2 captured by the first image systems VR1 to VR4 to determine the positions of the redundant patterns DUM1 and DUM2.
控制電腦CTRL啟動第一對準臺ST1,藉以調整薄膜圖案相位差膜FPR的位置,致使薄膜圖案相位差膜FPR的參考線CTL能在藉由第三影像模組VR3與第四影像模組VR4所獲得的影像上看到。控制電腦CTRL比對並分析由第一影像系統之第三與第四影像模組VR3與VR4所獲得的影像、以及由第二影像系統之第三與第四影像模組VP3與VP4所獲得的影像,藉以啟動xy自動機器或第一對準臺ST1,致使薄膜圖案相位差膜FPR的參考線CTL以及面板參考線CTL_PNL位在容許對準誤差範圍AMR內。當薄膜圖案相位差膜FPR的參考線CTL與面板參考線CTL_PNL會合時,或對準誤差係在容許對準誤差範圍AMR內,控制電腦CTRL判斷出對準情況為良好,並啟動鼓DR以執行附著操作。The control computer CTRL activates the first alignment stage ST1 to adjust the position of the film pattern retardation film FPR, so that the reference line CTL of the film pattern retardation film FPR can be passed through the third image module VR3 and the fourth image module VR4. Seen on the obtained image. The control computer CTRL compares and analyzes the images obtained by the third and fourth image modules VR3 and VR4 of the first image system, and the images obtained by the third and fourth image modules VP3 and VP4 of the second image system. The image is used to activate the xy automatic machine or the first alignment stage ST1 such that the reference line CTL of the thin film pattern phase difference film FPR and the panel reference line CTL_PNL are within the allowable alignment error range AMR. When the reference line CTL of the thin film pattern phase difference film FPR and the panel reference line CTL_PNL meet, or the alignment error is within the allowable alignment error range AMR, the control computer CTRL determines that the alignment is good, and starts the drum DR to execute Attachment operation.
在第一對準臺ST1上對準薄膜圖案相位差膜FPR之後,控制電腦CTRL於x軸方向移動第一對準臺ST1,或移動鼓DR。如第12B圖與第12C圖所示,控制電腦CTRL將鼓DR的一表面與薄膜圖案相位差膜FPR予以接觸,並接著逆時針方向轉動鼓DR,藉以將薄膜圖案相位差膜FPR轉移到鼓DR。繼之,控制電腦CTRL脫落附著或黏附在鼓DR上的薄膜圖案相位差膜FPR的脫模薄膜,以曝露薄膜圖案相位差膜FPR的接著劑(adhensive)。藉由一自動去除裝置,脫模薄膜被手動地或自動地予以脫落。After the film pattern phase difference film FPR is aligned on the first alignment stage ST1, the control computer CTRL moves the first alignment stage ST1 in the x-axis direction, or moves the drum DR. As shown in FIGS. 12B and 12C, the control computer CTRL contacts a surface of the drum DR with the film pattern retardation film FPR, and then rotates the drum DR counterclockwise, thereby transferring the film pattern retardation film FPR to the drum. DR. Next, the control computer CTRL peels off the release film of the thin film pattern retardation film FPR attached or adhered to the drum DR to expose the adhesive of the thin film pattern retardation film FPR. The release film is manually or automatically peeled off by an automatic removal device.
基於顯示面板PNL之對準標記AK2、AK5之透過第二影像系統VP1至VP4的第三影像模組VP3與第四影像模組VP4所獲得的影像,控制電腦CTRL啟動第二對準臺ST2,因此能調整顯示面板PNL的對準情況。由於當薄膜圖案相位差膜FPR與顯示面板PNL調整時,僅薄膜圖案相位差膜FPR的位置能基於顯示面板PNL來調整,調整顯示面板PNL的位置的程序可以省略。The control computer CTRL starts the second alignment station ST2 based on the images obtained by the third image module VP3 and the fourth image module VP4 of the second image systems VP1 to VP4 of the alignment marks AK2 and AK5 of the display panel PNL. Therefore, the alignment of the display panel PNL can be adjusted. When the film pattern phase difference film FPR and the display panel PNL are adjusted, only the position of the film pattern phase difference film FPR can be adjusted based on the display panel PNL, and the procedure of adjusting the position of the display panel PNL can be omitted.
控制電腦CTRL比對並分析從第一影像系統VR1至VR4與第二影像系統VP1至VP4所接收的影像,以及當介於薄膜圖案相位差膜FPR的參考線CTL與面板參考線CTL_PNL之間的距離在容許對準誤差範圍AMR內,控制電腦CTRL將鼓DR朝向第二對準系統ST2移動。如第12D圖所示,當將包繞鼓DR的薄膜圖案相位差膜FPR的接著劑與顯示面板PNL的表面予以接觸並於逆時針方向轉動鼓DR時,控制電腦CTRL將薄膜圖案相位差膜FPR附接至顯示面板PNL上。The control computer CTRL compares and analyzes images received from the first image systems VR1 to VR4 and the second image systems VP1 to VP4, and when between the reference line CTL of the thin film pattern phase difference film FPR and the panel reference line CTL_PNL The distance within the allowable alignment error range AMR, the control computer CTRL moves the drum DR toward the second alignment system ST2. As shown in FIG. 12D, when the adhesive of the thin film pattern retardation film FPR surrounding the drum DR is brought into contact with the surface of the display panel PNL and the drum DR is rotated counterclockwise, the control computer CTRL applies the film pattern retardation film. The FPR is attached to the display panel PNL.
由於薄膜圖案相位差膜FPR不包含分離的對準標記,薄膜圖案相位差膜FPR可以連續生產程序來製造。Since the thin film pattern retardation film FPR does not contain separate alignment marks, the thin film pattern retardation film FPR can be manufactured by a continuous production process.
在上述之本發明的實施例中,雖然轉動鼓DR係用於作為朝顯示面板PNL移動薄膜圖案相位差膜FPR或轉換之用的工具,以致薄膜圖案相位差膜FPR可與顯示面板PNL接合,於本發明的其他實施例中,亦可利用其他的裝置或手段。In the above-described embodiment of the present invention, although the rotary drum DR is used as a tool for moving the thin film pattern phase difference film FPR or conversion toward the display panel PNL, the thin film pattern retardation film FPR can be bonded to the display panel PNL.

本發明的一實施例包含在移動表面處理薄膜73時將對準薄膜77塗覆於薄膜基底73上,如第16圖與第17圖所示,並弄乾對準薄膜77。An embodiment of the present invention includes applying an alignment film 77 to the film substrate 73 while moving the surface treatment film 73, as shown in Figs. 16 and 17, and drying the alignment film 77.
依據本發明的一實施例,塗覆於薄膜基底73上的對準薄膜77的前表面暴露於45度(45°)極化紫外線,同時薄膜基底73藉由一預設速度於一方向移動,然後具有紫外線暴露前表面的對準薄膜77透過光罩78利用-45度(-45°)極化紫外線予以紫外線曝光。隨後,依據本發明的一實施例,當薄膜基底73藉由一預設速度延一方向移動時,含有光固化劑(light curing agent)的液晶層形成在具有45度對準圖案77a與-45度對準圖案77b的對準薄膜77上,接著紫外線照射液晶層,以固化並弄乾液晶層。圖案層74形成在經歷了曝光與液晶塗覆過程的薄膜基底73上,而該圖案層74包含具有-45度對準角度的液晶層的第一極化選擇圖案PR1、以及具有45度對準角度的液晶層的第二極化選擇圖案PR2。According to an embodiment of the present invention, the front surface of the alignment film 77 coated on the film substrate 73 is exposed to 45-degree (45°) polarized ultraviolet rays while the film substrate 73 is moved in one direction by a predetermined speed. The alignment film 77 having the front surface of the ultraviolet ray is then exposed to ultraviolet light by a polarizing ultraviolet light of -45 degrees (-45°) through the reticle 78.

And a protective layer 71 is formed on the film substrate 73.
如第16圖與第17圖所示,製造薄膜圖案相位差膜FPR的過程沒有包含在薄膜圖案相位差膜FPR上的對準標記,因此,當移動薄膜基底73而沒有停止薄膜基底73時,如第15圖所示的不同層可連續形成在薄膜基底73上。As shown in FIGS. 16 and 17, the process of manufacturing the thin film pattern retardation film FPR does not include the alignment mark on the thin film pattern retardation film FPR, and therefore, when the film substrate 73 is moved without stopping the film substrate 73, Different layers as shown in Fig. 15 can be continuously formed on the film substrate 73.
如上所述,依據本發明的實施例,圖案相位差膜與顯示面板利用極化選擇圖案互相對準,用於分離在圖案相位差膜內的左眼影像與右眼影像的極化特性,以致於圖案相位差膜與顯示面板可正確地對準,並互相接合而無須在圖案相位差膜上形成分隔的對準標記。另外,依據該等實施例,由於在製造圖案相位差膜的過程中,並不需要分離的過程來形成對準標記,對於圖案相位差膜而言,將可易於施行過程,而對製造圖案相位差膜而言,可節省成本。又,依據該等實施例,在顯示面板中所形成的對準標記來標記出容許對準誤差範圍,使之能被直覺地識別出來,致使介於圖案相位差膜與顯示面板之間的對準誤差能直覺正確地計算出來。As described above, according to an embodiment of the present invention, the pattern phase difference film and the display panel are aligned with each other by using a polarization selection pattern for separating polarization characteristics of the left eye image and the right eye image in the pattern phase difference film, so that The pattern retardation film and the display panel are properly aligned and bonded to each other without forming separate alignment marks on the pattern retardation film. In addition, according to the embodiments, since the alignment marks are not required to be formed in the process of manufacturing the pattern retardation film, for the pattern retardation film, the process can be easily performed, and the pattern phase is manufactured. In terms of poor film, it can save costs. Moreover, in accordance with the embodiments, the alignment marks formed in the display panel mark the allowable alignment error range so that it can be intuitively recognized, resulting in a pair between the pattern retardation film and the display panel. The quasi-error can be calculated intuitively and correctly.
依據如第18圖所示之正面模式(forward model)及如第19圖所示之翻轉模式(reverse),一立體影像顯示裝置可應用不同的組裝方法。在正面模式中,顯示面板係以一前面態式而組裝於一主系統,而在上側與下側之間並未翻轉。相反地,在翻轉模式中,顯示面板係以一反轉態式而組裝於一主系統,其中,上側與下側相互翻轉。According to the forward model shown in Fig. 18 and the reverse mode shown in Fig. 19, a stereoscopic image display device can apply different assembly methods. In the front mode, the display panel is assembled to a main system in a frontal state without being flipped between the upper and lower sides. Conversely, in the flip mode, the display panel is assembled in a reverse mode to a main system in which the upper side and the lower side are flipped over each other.
在正面模式中,薄膜圖案相位差膜FPR的第一極化選擇圖案PR1傳送顯示在顯示面板PNL之奇數顯示線上的左眼影像作為第一極化光,並且傳送顯示在顯示面板PNL之偶數顯示線上的右眼影像作為第二極化光。依據本發明之的實施例,在正面模式中,極化眼鏡PGLS的左眼濾光片通過經由第一極化選擇圖案PR1入射的第一極化左眼影像光,而極化眼鏡PGLS的右眼濾光片通過經由第一極化選擇圖案PR1入射的第二極化右眼影像光。如同正面模式的相同方式,於翻轉模式中,薄膜圖案相位差膜FPR可與顯示面板接合在一起。In the front mode, the first polarization selection pattern PR1 of the thin film pattern phase difference film FPR transmits the left eye image displayed on the odd display line of the display panel PNL as the first polarized light, and transmits the even display on the display panel PNL. The right eye image on the line acts as the second polarized light. According to an embodiment of the present invention, in the front mode, the left-eye filter of the polarized glasses PGLS passes the first polarized left-eye image light incident through the first polarization selection pattern PR1, and the right of the polarized glasses PGLS The eye filter passes through the second polarized right eye image light incident through the first polarization selection pattern PR1. In the same manner as the front mode, in the flip mode, the thin film pattern retardation film FPR can be bonded to the display panel.
依據本發明的一實施例,在翻轉模式中,右眼影像資料顯示在顯示面板PNL的奇數顯示線上,且右眼影像光經由薄膜圖案相位差膜FPR的第一極化選擇圖案PR1傳送出去,作為第一極化光。在翻轉模式中,左眼影像資料顯示在顯示面板PNL的偶數顯示線上,且左眼影像光經由薄膜圖案相位差膜FPR的第二極化選擇圖案PR2傳送出去,作為第二極化光。因此,如同正面模式的相同方式,由於薄膜圖案相位差膜FPR附接至在翻轉模式的顯示面板PNL上,而如同於正面模式的相同資料輸入至顯示面板PNL,觀看者透過極化眼鏡PGLS的左眼濾光片看到右眼影像,並透過極化眼鏡PGLS的右眼濾光片看到左眼影像,因此,觀看者感受到反立體(pseudoscopic)影像而不是觀看一正常的3D影像。在翻轉模式中,主系統可傳送互相相反的左眼影像與右眼影像到顯示面板PNL的驅動電路,以匹配顯示在顯示面板PNL上的左眼影像與右眼影像與薄膜圖案相位差膜FPR的圖案的極化特性。於此種情形下,用於翻轉及對準左眼影像與右眼影像的電路與軟體可加入至主系統中。依據本發明的一實施例,以相較於正面模式薄模圖案相位差膜FPR之翻轉模式薄模圖案相位差膜FPR一線上移(或下移),藉由接合薄模圖案相位差膜FPR與顯示面板,一正常3D影像可予以實施,而無須改變輸入到顯示面板PNL之驅動電路的左眼/右眼影像資料的排列序。According to an embodiment of the present invention, in the flip mode, the right eye image data is displayed on the odd display line of the display panel PNL, and the right eye image light is transmitted through the first polarization selection pattern PR1 of the thin film pattern phase difference film FPR. As the first polarized light. In the flip mode, the left eye image data is displayed on the even display line of the display panel PNL, and the left eye image light is transmitted through the second polarization selection pattern PR2 of the thin film pattern phase difference film FPR as the second polarized light. Therefore, as in the same manner as the front mode, since the thin film pattern phase difference film FPR is attached to the display panel PNL in the flip mode, and the same material as the front mode is input to the display panel PNL, the viewer passes through the polarized glasses PGLS. The left eye filter sees the right eye image and the left eye image is seen through the right eye filter of the polarized glasses PGLS. Therefore, the viewer perceives a pseudoscopic image rather than viewing a normal 3D image. In the flip mode, the main system can transmit the opposite left eye image and the right eye image to the display panel PNL driving circuit to match the left eye image and the right eye image and the film pattern retardation film FPR displayed on the display panel PNL. The polarization characteristics of the pattern. In this case, circuits and software for flipping and aligning the left eye image with the right eye image can be added to the host system. According to an embodiment of the present invention, the thin mode retardation film FPR is shifted (or shifted downward) on the line by the flip mode thin film retardation film FPR of the front mode thin film retardation film FPR, by bonding the thin mode retardation film FPR And the display panel, a normal 3D image can be implemented without changing the arrangement of the left eye/right eye image data input to the driving circuit of the display panel PNL.

第22圖與第23圖為說明對應於正面模式的對準標記、以及對應於翻轉模式的對準標記共同形成於顯示面板PNL的平面示意圖。第22圖與第23圖所示之對準標記為形成在顯示面板中央之二相對側的第二對準標記與第五對準標記。22 and 23 are schematic plan views showing that alignment marks corresponding to the front mode and alignment marks corresponding to the flip mode are collectively formed on the display panel PNL. The alignment marks shown in Figs. 22 and 23 are second alignment marks and fifth alignment marks formed on the opposite sides of the center of the display panel.

The alignment marks AK2(R), AK5(R) corresponding to the flip mode are aligned with the second reference line CTL2 of the thin film pattern phase difference film FPR.
正面模式與翻轉模式對應的對準標記AK2(F)、AK5(F)與對準標記AK2(R)、AK5(R)互相可具有不同的形狀,以致左側與右側可易於識別出來,例如,正面模式與翻轉模式對應的對準標記可設計成互相為對稱的。對準標記的每一個可包含記號、特性等等。依據本發明的一實施例,一些特性可正常地形成在正面模式對應的對準標記AK2(F)、AK5(F),而其他特性可反方向地形成在翻轉模式對應的對準標記AK2(R)、AK5(R)。不像是正面模式顯示面板,由於在翻轉模式顯示面板PNL中,上側與下側為互相反向,若相關於正面模式姿態,特性為上下顛倒印刷,當顯示面板PNL巔倒配合於翻轉模式時,該等特性可正常地予以察看。The alignment marks AK2(F), AK5(F) and the alignment marks AK2(R), AK5(R) corresponding to the front mode and the flip mode may have different shapes from each other, so that the left side and the right side are easily identifiable, for example, The alignment marks corresponding to the front mode and the flip mode can be designed to be symmetrical to each other. Each of the alignment marks can include a mark, a characteristic, and the like. According to an embodiment of the present invention, some characteristics may normally form the alignment marks AK2(F), AK5(F) corresponding to the front mode, and other characteristics may form the alignment mark AK2 corresponding to the flip mode in the opposite direction ( R), AK5 (R). Unlike the front mode display panel, since the upper side and the lower side are opposite to each other in the flip mode display panel PNL, if it is related to the front mode posture, the characteristic is upside down printing, when the display panel PNL is tripped in the flip mode. These characteristics can be viewed normally.

如上所述,依據該等實施例,當極化選擇圖案之一線被加到薄膜圖案相位差膜FPR,而薄膜圖案相位差膜FPR與翻轉模式顯示面板對準,薄膜圖案相位差膜將向上偏移或向下偏移一線寬(或一圖案寬度)。結果,該等實施例允許薄膜圖案相位差膜具有可兼容應用於正面與翻轉模式顯示面板的相同結構,致使正常3D影像可施行於正面與翻轉模式,而無須改變互相輸入到顯示面板驅動電路的左眼/右眼影像資料。As described above, according to the embodiments, when one line of the polarization selection pattern is applied to the thin film pattern retardation film FPR, and the thin film pattern retardation film FPR is aligned with the flip mode display panel, the film pattern retardation film will be biased upward. Shift or downward offset by a line width (or a pattern width). As a result, the embodiments allow the thin film pattern retardation film to have the same structure compatible for use in the front side and flip mode display panels, so that normal 3D images can be applied to the front side and flip mode without changing the mutual input to the display panel driving circuit.
