Description
本發明是關於一種偏光片檢查裝置，更詳細而言是關於一種可檢查偏光片之黑模式之偏光片檢查裝置。The present invention relates to a polarizer inspection apparatus, and more particularly to a polarizer inspection apparatus capable of inspecting a black mode of a polarizer.
偏光片用以將光往特定方向進行偏光。偏光片係例如用以於液晶顯示裝置(LCD)，黏貼於液晶胞之雙面以形成液晶面板。就理論上而言，偏光片在2片偏光片呈正交而重疊時(亦即，2片偏光片之穿透軸互呈垂直而重疊時)，不應會有通過偏光片之光。此時，拍攝有偏光片之影像係光受到阻隔而顯示黑色，此稱為偏光片之黑模式(Black Mode)。 一般而言，偏光片之黑模式狀態是從設於一側之光源，對呈正交而重疊之2片偏光片照射光，設於另一側之相機拍攝偏光片而檢查。然而，從光源照射之光不僅包含可見光，亦包含紅外線及紫外線，具有拍攝了偏光片之黑模式之影像未顯示黑色而顯示白色的問題點。 亦即，偏光片一般製造為使得可見光區段之光進行偏光。因此，當從光源照射之光包含紅外線及紫外線時，即使將2片偏光片呈正交而重疊，紅外線及紫外線區段之光仍不受阻隔而通過，因此使得拍攝了偏光片之黑模式之影像顯示白色。此時，具有不能檢查偏光片之黑模式本身，也不能藉由偏光片之黑模式來檢測存在於偏光片之缺陷的問題點。 具體而言，於偏光片之黑模式狀態下，理論上光無法通過偏光片，因此拍攝有偏光片之影像整體應顯示黑色，但於製造偏光片之過程中，於偏光片存在缺陷(例如染料不均之染著、黏著不良、表面刮痕、異物等)時，由於無法100%阻隔光，因此於拍攝有偏光片之黑模式之影像本身顯示白色的情況下，不能檢測該類偏光片之缺陷。The polarizer is used to polarize light in a specific direction. The polarizer is used, for example, in a liquid crystal display device (LCD), and is adhered to both sides of a liquid crystal cell to form a liquid crystal panel. Theoretically, when the polarizers are orthogonal to each other and the two polarizers overlap each other (that is, when the transmission axes of the two polarizers are perpendicular to each other), there should be no light passing through the polarizer. At this time, the image in which the polarizer is photographed is blocked to display black, which is called the black mode of the polarizer. In general, the black mode state of the polarizer is to illuminate two polarizers that are orthogonal to each other from the light source provided on one side, and the polarizer is photographed by the camera provided on the other side. However, the light irradiated from the light source includes not only visible light but also infrared rays and ultraviolet rays, and the image in which the black mode in which the polarizer is photographed does not display black and displays white. That is, the polarizer is generally manufactured such that light in the visible light section is polarized. Therefore, when the light irradiated from the light source includes infrared rays and ultraviolet rays, even if the two polarizers are orthogonally overlapped, the light of the infrared rays and the ultraviolet rays are not blocked, and thus the image display of the black mode in which the polarizer is photographed is performed. white. At this time, there is a black mode in which the polarizer cannot be inspected, and the problem of the defect existing in the polarizer cannot be detected by the black mode of the polarizer. Specifically, in the black mode state of the polarizer, theoretically, the light cannot pass through the polarizer, and therefore the image on which the polarizer is photographed should display black as a whole, but in the process of manufacturing the polarizer, there is a defect in the polarizer (for example, a dye). In the case of uneven dyeing, poor adhesion, surface scratches, foreign matter, etc., since the light cannot be blocked 100%, when the image in which the black mode of the polarizer is photographed is white, the polarizer cannot be detected. defect.
發明所欲解決之課題 本發明之目的在於提供一種偏光片檢查裝置，其係可檢查偏光片之黑模式。 解決課題之手段 1.本發明之一實施形態之偏光片檢查裝置包括：光源，其係產生光；照射部，其係於穿透軸呈垂直而相互交叉之偏光片，照射從前述光源產生之光；攝影部，其係從前述照射部之相反側，拍攝前述偏光片；光傳遞構件，其係將從前述光源產生之光，傳遞給前述照射部；連通部，其係分別連通前述光源與前述光傳遞構件、及前述光傳遞構件與前述照射部；及波長阻隔濾光片，其係設於前述連通部，從前述光源所產生的光，阻隔紅外線區段及紫外線區段中之至少一者。 2.如前述項目1，其特徵在於：前述光傳遞構件為光纖；前述連通部為光纖配接器。 3.如前述項目1，其中前述連通部包括：第1連通部，其係連通前述光源與前述光傳遞構件之一端；及第2連通部，其係連通前述光傳遞構件之另一端與前述照射部；前述波長阻隔濾光片包括：第1波長阻隔濾光片，其係設於前述第1連通部，從前述光源所產生的光，阻隔紅外線區段及紫外線區段中之某一者；及第2波長阻隔濾光片，其係設於前述第2連通部，從前述光源所產生的光，阻隔紅外線區段及紫外線區段中之另一者。 4.如前述項目1，其中前述攝影部包括紅外線阻隔濾光片；前述波長阻隔濾光片係從前述光源所產生的光，阻隔紫外線區段。 發明之效果 若依據本發明之實施形態，藉由利用波長阻隔濾光片，從光源所產生的光，阻隔紅外線及紫外線區段，可使得拍攝偏光片之影像顯示黑色，藉此可藉由攝影影像，檢查偏光片之黑模式。屆時，若於偏光片存在有缺陷，則於攝影影像，缺陷所存在的部分會發生亮度差，因此可容易檢測偏光片有無缺陷。SUMMARY OF THE INVENTION Problem to be Solved by the Invention An object of the present invention is to provide a polarizer inspection apparatus which can inspect a black mode of a polarizer.

用以實施發明之形態 以下參考第1圖、第2圖，來說明本發明之偏光片檢查裝置之具體實施形態。然而，該等只是作為例示之實施例，本發明不受該等所限制。 說明本發明時，判斷關於本發明之習知技術之具體說明並無需要，得脫離本發明之要旨時，則省略其詳細說明。然後，後述之用語是考慮本發明之功能所定義的用語，該等可依使用者、運用者之意圖或慣例等來變更。因此，其定義應根據本說明書整體所記載的內容來定義。 本發明之技術思想係由申請專利範圍的記載來決定，以下實施形態只是用以對於具有本發明所屬技術領域中之一般知識的人士，有效率地說明進步的本發明之技術思想。 第1圖係表示本發明之一實施形態之偏光片檢查裝置之圖。 參考第1圖，偏光片檢查裝置100包括：光源102、連通部104、光傳遞構件106、波長阻隔濾光片108、照射部110、偏光片112、及攝影部114。 光源102發揮產生光的作用。光源102可利用金屬鹵素燈(Metal Halide Lamp)、LED燈(Light Emitting Diode Lamp：發光二級體燈)等，但不限定於該等，可利用其以外之各種光源。 連通部104包括第1連通部104-1及第2連通部104-2。第1連通部104-1係於光源102與光傳遞構件106之間，連通光源102與光傳遞構件106。第2連通部104-2係於照射部110與光傳遞構件106之間，連通照射部110與光傳遞構件106。 光傳遞構件106發揮將從光源102產生之光，傳遞給照射部110之作用。光傳遞構件106可利用例如光纖(Optical Fiber)。此時，可減少從光源102產生的光之損失，同時迅速傳遞給照射部110。利用光纖作為光傳遞構件106時，作為第1連通部104-1及第2連通部104-2可利用光纖配接器(Optical Fiber Adaptor)。然而，光傳遞構件106不限定於光纖，可利用其以外可傳遞光之各種構件(光導波管等)。 波長阻隔濾光片108發揮從光源102所產生的光，阻隔紅外線(IR)及紫外線(UV)區段之作用。波長阻隔濾光片108包括第1波長阻隔濾光片108-1及第2波長阻隔濾光片108-2。第1波長阻隔濾光片108-1可設於第1連通部104-1，第2波長阻隔濾光片108-2可設於第2連通部104-2。然而，不限定於此，第1波長阻隔濾光片108-1及第2波長阻隔濾光片108-2亦可全都設在第1連通部104-1及第2連通部104-2。 第1波長阻隔濾光片108-1可設置為從光源102產生之光，阻隔紅外線(IR)區段，第2波長阻隔濾光片108-2可設置為從光源102產生之光，阻隔紫外線(UV)區段。然而，不限定於該等，第1波長阻隔濾光片108-1亦可設置為從光源102產生之光，阻隔紫外線(UV)區段，第2波長阻隔濾光片108-2亦可設置為從光源102產生之光，阻隔紅外線(IR)區段。此時，光源102所產生的光之紅外線區段及紫外線區段，係由第1波長阻隔濾光片108-1及第2波長阻隔濾光片108-2阻隔，因此經由光傳遞構件106傳遞給照射部110之光成為可見光區段之光。 在此，藉由於連通部104設置波長阻隔濾光片108，可利用少數(最大2個)以及小尺寸之波長阻隔濾光片108，從光源102所產生的光，阻隔紅外線及紫外線區段，藉此可刪減偏光片檢查裝置100之製造成本。 照射部110發揮於偏光片112照射光之作用。屆時，照射部110會於偏光片112，照射可見光區段。照射部110可由透明材質組成。此時，從光傳遞構件106傳遞之光係經由照射部110照射於偏光片112。 偏光片112包括第1偏光片112-1及第2偏光片112-2。第1偏光片112-1之穿透軸及第2偏光片112-2之穿透軸設置為相互呈正交。例如第1偏光片112-1之穿透軸設置為橫向(↔)時，第2偏光片112-2設置為縱向(↕)。第1偏光片112-1與第2偏光片112-2分別設置為使得可見光區段之光進行偏光。 攝影部114係從照射部110之相反方向拍攝偏光片112。在此，第1偏光片112-1及第2偏光片112-2係設置為分別將可見光區段之光進行偏光，穿透軸相互呈正交，因此照射於偏光片112之光(亦即可見光區段之光)無法通過偏光片112。此時，攝影部114不能接受光，拍攝有偏光片112之影像顯示黑色。因此，可藉由拍攝了偏光片112之影像來檢查偏光片112之黑模式。 另，於攝影部114中，可設置紅外線(IR)阻隔濾光片。例如攝影部114中之鏡片可於已施加紅外線阻隔處理的狀態下製造。此時，波長阻隔濾光片108可具體實現從光源102所產生的光，阻隔紫外線(UV)區段。 若依據本發明之實施形態，藉由利用波長阻隔濾光片108，從光源102所產生的光，阻隔紅外線及紫外線區段，可使得拍攝偏光片112之影像顯示黑色，藉此可藉由攝影影像，檢查偏光片112之黑模式。屆時，若於偏光片112存在有缺陷，則於攝影影像，缺陷所存在的部分會發生亮度差，因此可容易檢測偏光片112有無缺陷。 第2圖係於本發明之一實施形態之偏光片檢查裝置，比較適用了波長阻隔濾光片的情況與未適用的情況下之攝影影像之圖。 參考第2圖，適用了波長阻隔濾光片108時，確認拍攝有偏光片112之影像顯示黑色。另，未適用波長阻隔濾光片108時，確認拍攝有偏光片112之影像顯示白色 以上透過代表性之實施形態來說明了本發明，但具有本發明所屬技術領域中之一般知識的人士，應理解對於上述實施形態，可於不脫離本發明範疇之範圍內施以各種變形。因此，本發明之權利範圍不得限定於所說明的實施形態來制訂，不僅須藉由後述之申請專利範圍，還須藉由與該申請專利範圍同等之技術等來制訂。MODE FOR CARRYING OUT THE INVENTION A specific embodiment of the polarizer inspection device of the present invention will be described below with reference to Figs. 1 and 2 . However, these are merely exemplary embodiments, and the invention is not limited thereto. In the description of the present invention, the detailed description of the prior art of the present invention is not required, and the detailed description thereof will be omitted when the gist of the present invention is omitted. Then, the terms to be described later are terms defined in consideration of the functions of the present invention, and these may be changed depending on the intention of the user, the user, or the convention. Therefore, the definition should be defined in accordance with the contents described in the entire specification. The technical idea of the present invention is determined by the description of the scope of the patent application, and the following embodiments are merely used to efficiently explain the technical idea of the present invention to those having ordinary knowledge in the technical field to which the present invention pertains. Fig. 1 is a view showing a polarizer inspection device according to an embodiment of the present invention. Referring to Fig. 1, a polarizer inspection device 100 includes a light source 102, a communication portion 104, a light transmission member 106, a wavelength blocking filter 108, an illuminating portion 110, a polarizer 112, and a photographing portion 114. The light source 102 functions to generate light. The light source 102 can be a metal halide lamp (Metal Halide Lamp) or an LED lamp (Light Emitting Diode Lamp), but is not limited thereto, and various light sources other than the above can be used. The communication unit 104 includes a first communication unit 104-1 and a second communication unit 104-2. The first communication portion 104-1 is connected between the light source 102 and the light transmission member 106, and communicates the light source 102 and the light transmission member 106. The second communication portion 104-2 is connected between the irradiation unit 110 and the light transmission member 106, and communicates the irradiation unit 110 and the light transmission member 106. The light transmitting member 106 functions to transmit the light generated from the light source 102 to the illuminating unit 110. The light transmitting member 106 can utilize, for example, an optical fiber. At this time, the loss of light generated from the light source 102 can be reduced, and at the same time, it is quickly transmitted to the illuminating portion 110. When an optical fiber is used as the optical transmission member 106, an optical fiber adapter (Optical Fiber Adaptor) can be used as the first communication portion 104-1 and the second communication portion 104-2. However, the light-transmitting member 106 is not limited to an optical fiber, and various members (light-guide tubes, etc.) capable of transmitting light other than the above may be used. The wavelength blocking filter 108 functions to generate light from the light source 102 and blocks infrared (IR) and ultraviolet (UV) sections. The wavelength blocking filter 108 includes a first wavelength blocking filter 108-1 and a second wavelength blocking filter 108-2. The first wavelength blocking filter 108-1 may be provided in the first communication portion 104-1, and the second wavelength blocking filter 108-2 may be provided in the second communication portion 104-2. However, the first wavelength blocking filter 108-1 and the second wavelength blocking filter 108-2 may be provided in the first communication portion 104-1 and the second communication portion 104-2, respectively. The first wavelength blocking filter 108-1 may be disposed as light generated from the light source 102 to block an infrared (IR) section, and the second wavelength blocking filter 108-2 may be disposed to generate light from the light source 102 to block ultraviolet rays. (UV) section. However, the first wavelength blocking filter 108-1 may be provided as light generated from the light source 102 to block ultraviolet (UV) sections, and the second wavelength blocking filter 108-2 may be provided. For the light generated from the light source 102, the infrared (IR) section is blocked. At this time, the infrared ray segment and the ultraviolet ray segment of the light generated by the light source 102 are blocked by the first wavelength blocking filter 108-1 and the second wavelength blocking filter 108-2, and thus are transmitted via the light transmitting member 106. The light given to the illuminating unit 110 becomes light in the visible light section. Here, by providing the wavelength blocking filter 108 by the connecting portion 104, a small number (up to two) and a small-sized wavelength blocking filter 108 can be utilized to block the infrared rays and the ultraviolet rays from the light generated by the light source 102. Thereby, the manufacturing cost of the polarizer inspection apparatus 100 can be reduced. The illuminating unit 110 functions to illuminate the polarizer 112. At this time, the illuminating unit 110 will illuminate the visible light section on the polarizer 112. The illuminating unit 110 may be composed of a transparent material. At this time, the light transmitted from the light transmitting member 106 is irradiated to the polarizer 112 via the irradiation unit 110. The polarizer 112 includes a first polarizer 112-1 and a second polarizer 112-2. The transmission axis of the first polarizer 112-1 and the transmission axis of the second polarizer 112-2 are disposed to be orthogonal to each other. For example, when the transmission axis of the first polarizer 112-1 is set to the lateral direction (↔), the second polarizer 112-2 is set to the longitudinal direction (↕). The first polarizer 112-1 and the second polarizer 112-2 are respectively disposed such that light in the visible light section is polarized. The photographing unit 114 takes the polarizer 112 from the direction opposite to the irradiation unit 110. Here, the first polarizer 112-1 and the second polarizer 112-2 are arranged to polarize the light in the visible light section, and the transmission axes are orthogonal to each other, thereby illuminating the light of the polarizer 112 (ie, the visible light region). The light of the segment cannot pass through the polarizer 112. At this time, the photographing unit 114 cannot receive light, and the image in which the polarizer 112 is photographed displays black. Therefore, the black mode of the polarizer 112 can be checked by taking an image of the polarizer 112. Further, an infrared (IR) blocking filter may be provided in the photographing unit 114. For example, the lens in the photographing unit 114 can be manufactured in a state in which the infrared ray blocking treatment has been applied. At this time, the wavelength blocking filter 108 can specifically realize the light generated from the light source 102, blocking the ultraviolet (UV) section. According to the embodiment of the present invention, by using the wavelength blocking filter 108, the light generated from the light source 102 blocks the infrared rays and the ultraviolet rays, so that the image of the polarizing film 112 can be displayed in black, thereby enabling photography. Image, check the black mode of the polarizer 112. At this time, if there is a defect in the polarizer 112, a difference in luminance occurs in the portion where the defect exists in the photographic image, so that it is possible to easily detect the presence or absence of the defect of the polarizer 112. Fig. 2 is a view showing a polarizing plate inspection device according to an embodiment of the present invention, in which a wavelength blocking filter is applied and a photographic image in the case where it is not applied. Referring to Fig. 2, when the wavelength blocking filter 108 is applied, it is confirmed that the image on which the polarizer 112 is photographed is black. Further, when the wavelength blocking filter 108 is not applied, it is confirmed that the image in which the polarizing film 112 is imaged is white and the representative embodiment is described. However, those having the general knowledge in the technical field of the present invention should It is to be understood that various modifications may be made without departing from the scope of the invention. Therefore, the scope of the present invention is not limited to the embodiments described, and is not limited by the scope of the patent application described below, but also by the same technology as the scope of the patent application.
