另一方面,使用具有可使特定波長之光順利穿透,而 ’ 5 遮斷其他波長之光之特性的彩色慮光片’可實現彩色液晶 顯示面板。即,R濾光片可使紅色光順利穿透,且使其他波 長之光無法穿透,G濾光片可使綠色光順利穿透,且使其他 波長之光無法穿透,而B濾光片則可使藍色光順利穿透’且 使其他波長之光無法穿透。 10 生產液晶顯示面板的業者判斷液晶顯示面板是否有瑕 疵的基準在於液晶顯示面板所含之瑕疵晶胞數。瑕疵晶胞 可分成亮點晶胞和暗點晶胞,但通常可容許之亮點晶胞數 較暗點晶胞數嚴格。根據此種理由,將亮點晶胞暗點化可 提高液晶顯示面板的產率。例如,在完全不能容許有亮點 ‘ 15晶胞存在,而可容許1個暗點晶胞存在時,若在具有一個亮 點晶胞之液晶顯示面板將亮點晶胞替換成暗點晶胞,液晶 顯示面板即可成為正常面板。 專利文獻1揭示使亮點晶胞暗點化來修復液晶顯示面 板的技術。具體地參照該修復技術看來,為使因異物引起 2〇之亮點晶胞暗點化,係將雷射照射在黑色矩陣上,以、溶化 黑色矩陣’然後將已溶化之黑色矩陣的物質引導至異物 处、X使儿·、、、占日日胞暗點化。但是,前述方式在溶化黑色矩 陣日守,已令化之黑色矩陣的物質會移動至與瑕疵晶胞隣接 之正“曰胞,此時會有連正常晶胞都被暗點化的嚴重問題 6 200827819 【專利文獻1】韓國專利公開第2006-0067042號公報 發明揭示 5 發明所欲解決之問題 本發明者了解到,需要可使對隣接晶胞之影響最小 化,並使亮點晶胞暗點化的方案。即,藉由將雷射直接照 射在透光之晶胞區域(彩色濾光片區域),來代替熔化黑色矩 陣,而完成本發明。 10 但是,以雷射照射彩色濾光片使瑕疵像素暗點化的方 式有如第2圖所說明之問題點。 一般而言,在雷射照射時,雷射穿透的深度越大,雷 射的能量或強度就下降的越多,而某種程度之雷射能源可 傳達至比較深的層。因此,如第2圖所示,即 b點已對準彩色遽光片17’還是會有-部分的能源傳達= 晶層15。由於傳達至液晶層的能源,會有在液晶㈣產生 氣體的可能,此種氣體就會成為液晶層内產生氣泡22的原 因。 20 入液晶層,故還 就算雷射能源無法傳達至液晶層,但由於在雷射的昭 射過程中於彩色濾光片產生之氣體等會侵 、 是會有氣泡產生的可能性。 產生於液晶層之氣、泡也會對所欲修復之像素以外 致命性曙。而且,也有__面_ B曰層的氣泡而無法❹的情形,必須盡量避免氣泡現 7 200827819 象的發生。 -

INSTRUCTIONS: [Technical Field] Technical Field The present invention relates to a technique for repairing a liquid crystal display panel, and more specifically, and the "Lv" is related to removing a mad pixel of a liquid crystal display panel. Method and apparatus for implementing the method. BACKGROUND OF THE INVENTION A liquid crystal display device adjusts the transmittance of a liquid crystal by an image signal to display an image. Therefore, the liquid crystal display device includes a liquid crystal display panel provided with a unit cell arranged in a matrix, and a drive circuit for controlling the light transmittance of each unit cell by an image signal. Fig. 1 is a view showing a simple structure of a unit cell of a conventional liquid crystal display panel. The liquid crystal display panel unit cell includes a liquid crystal layer 15 1 which is polarized by a voltage between a thin film transistor (τρτ) • 15 glass (10) color filter (CF) glass 19 to achieve full color R, G, color-changing light film 17; and controllable ship crystal-shaped partial wire, joint light transmittance of the half (four) circuit layer 12. Further, the unit cell of the liquid crystal display panel further includes a pixel electrode 13, an alignment film 14, a common electrode 16, a black matrix a, and the like. 20 The principle of adjusting the brightness of the unit cell is as follows. Light supplied from a backlight (not shown) passes through the liquid crystal layer 15 and is polarized, and the polarized light passes through a polarizing plate (not shown) disposed outside the tft glass (10) CF glass 19 to enter the flesh. At this time, the closer the direction of the polarized light is to the direction perpendicular to the polarization direction of the polarizing plate, the more the polarized light passes through the polarizing plate, and the closer it is to the parallel side 5 200827819, the more the polarized light passes. Can pass the polarizer smoothly. As a result, the brightness of the unit cell can be adjusted by controlling the bias period of the liquid crystal layer by controlling the voltage applied between the two glasses. On the other hand, a color liquid crystal display panel can be realized by using a color filter sheet having a characteristic of allowing light of a specific wavelength to smoothly penetrate and '5 blocking light of other wavelengths'. That is, the R filter allows the red light to penetrate smoothly, and the light of other wavelengths cannot be penetrated. The G filter can smoothly penetrate the green light and make the light of other wavelengths unable to penetrate, and the B filter The film allows the blue light to penetrate smoothly and prevents other wavelengths of light from penetrating. 10 The manufacturer who produces the liquid crystal display panel determines whether the liquid crystal display panel has a flaw. The benchmark is the number of cells in the liquid crystal display panel. The germanium unit cell can be divided into a bright spot cell and a dark spot cell, but the number of bright spot cells can usually be tolerated to be stricter than the dark cell. For this reason, darkening the bright spot cells can increase the yield of the liquid crystal display panel. For example, when a bright spot '15 cell is completely unacceptable and one dark spot cell can be allowed to exist, if a liquid crystal display panel having a bright spot cell replaces the bright cell with a dark cell, the liquid crystal display The panel becomes the normal panel. Patent Document 1 discloses a technique of darkening a bright spot cell to repair a liquid crystal display panel. Referring specifically to the repair technique, in order to darken the bright spot cell caused by the foreign matter, the laser is irradiated onto the black matrix to melt the black matrix and then guide the dissolved black matrix material. To the foreign body, X makes the children, and, in the day, dark spots. However, the above-mentioned method dissolves the black matrix and keeps the material of the black matrix moving to the positive "cell" adjacent to the unit cell. At this time, there will be a serious problem that even the normal unit cell is darkened. 200827819 [Patent Document 1] Korean Patent Publication No. 2006-0067042 DISCLOSURE OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION The present inventors have learned that it is necessary to minimize the influence on adjacent cells and to darken the bright spot cells. That is, the present invention is completed by directly irradiating a laser in a light-transmissive cell region (color filter region) instead of melting a black matrix. 10 However, the color filter is irradiated with laser light. The way in which the pixels are darkened is as described in Figure 2. In general, the greater the depth of laser penetration during laser illumination, the more the energy or intensity of the laser decreases. The laser energy of a certain degree can be transmitted to a deeper layer. Therefore, as shown in Fig. 2, that point b is aligned with the color calender sheet 17' or there will be a part of the energy transmission = the crystal layer 15. Energy to the liquid crystal layer, There is a possibility of generating a gas in the liquid crystal (4), and this gas causes the generation of the bubble 22 in the liquid crystal layer. 20 Entering the liquid crystal layer, even if the laser energy cannot be transmitted to the liquid crystal layer, due to the laser emission process The gas generated in the color filter will invade, and there is a possibility that bubbles will be generated. The gas and bubbles generated in the liquid crystal layer will also be fatal to the outside of the pixel to be repaired. Moreover, there are also __面_ In the case of bubbles in the B layer, it is necessary to avoid the occurrence of bubbles. - A. To prevent the bubble phenomenon as described above, the penetration depth of the laser should be reduced. f ° The wavelength is the best, and the laser wavelength is shortened best - from the transparency of the color filter. : 5 Figure 3 shows a graph of the light transmittance characteristics of the color filter. The color W light sheet is excellent in light transmittance for light near a specific wavelength, but has low transmittance to light of other wavelengths. For example, the wavelength of light near the wavelength of 46 Gnm of the B-wave film is excellent, and the light is bright. The sheet η is excellent in light transmittance at a wavelength near 52 〇 nm, The light η is excellent in light transmittance for wavelengths above _ leg 10. Therefore, when it is desired to use a laser to change the physical properties of the color filter, it is preferable to use a color filter with low light transmittance. The laser of the wavelength to improve the efficiency of energy transmission. Referring to Figure 3, a laser is used to change the physical properties of 'R, G, Congguang, preferably using a wavelength of about 41 Gnm or less* 15 Laser. However, in the process of changing the physical properties of the color filter using a laser with a very short wavelength, there is a possibility that other components of the liquid crystal display panel (such as a polarizing plate) cannot be used. Therefore, it is best not to use it. Continuous use of short-wavelength lasers. 20 Here, in the way of directly irradiating a laser to a color filter to repair a liquid crystal display panel, from the light absorption rate of the color filter and the bubble phenomenon of the liquid crystal layer, The laser is the most important, and the present inventors focused on this point and studied it, and found that the color filter included in the pixel is irradiated with laser light by transmitting two different steps with different lasers. ,may have 8200827819 repairing flaws glimpse cell, and completed the present invention. The present invention has been made in view of the foregoing problems, and an object thereof is to provide a method for minimizing the influence of adjacent cells of a liquid crystal display panel, and capable of repairing a germanium cell of a liquid crystal display panel and for implementing the method. Installed, 5 sets. Means for Solving the Problems In order to solve the above problems, a method for repairing a liquid crystal display panel according to an embodiment of the present invention includes: illuminating a first laser to cause a π color filter included in a shouting pixel to be in a color light passing sheet a step of forming a gap near the glass; and a step of irradiating the second laser to change the physical properties of the color filter formed by the gap to reduce the light transmittance. At this time, the first laser is preferably a nanosecond pulse laser. Further, the first laser is preferably a pulsed laser having a wavelength of about the lung.

EFFECT OF THE INVENTION 200827819 According to the method and apparatus for repairing a liquid crystal display panel of the present invention, the influence on the adjacent unit cell of the liquid crystal display panel can be minimized by changing the physical properties of the color filter of the unit cell. Further, in the repairing method and apparatus for a liquid crystal display panel, the yield of the south liquid crystal display panel can be effectively improved by not darkening the van Gogh point without affecting the adjacent unit cell. BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments will be described in detail below, so that those skilled in the art can fully implement the present invention. Moreover, it is to be understood that the various embodiments of the present invention are different and are not mutually exclusive. For example, the specific shapes, configurations, and characteristics disclosed herein may be made in a single embodiment without departing from the spirit and scope of the invention. In addition, it is to be understood that the position and arrangement of the individual components in the embodiments disclosed herein may be modified without departing from the spirit and scope of the invention. Therefore, the detailed description is not to be construed as limited to the scope of the invention, and the scope of the present invention is to be construed as being limited to the scope of the claims. In the drawings, like reference characters indicate the same or similar functions in the various aspects. Fig. 4 is a flow chart showing the repair process of the liquid crystal display panel of one embodiment of the present invention. First of all, in order to repair the liquid crystal display panel, it is necessary to detect the bright spot cell (si) present in the liquid crystal display panel of 200827819-5. Since the manner in which the bright spot cells are detected is a well-known technique, the description thereof will be omitted. When a bright spot cell is found on the liquid crystal display panel, and the bright spot cell needs to be darkened, that is, when the bright spot cell is darkened to repair the liquid crystal display panel, the liquid crystal display panel is repaired. First, the first laser is used for the color filter of the spot cell and the film formation is performed (S2). The reason why the gap between the color filter and the light sheet is formed before the physical properties of the color filter are changed is that the physical properties of the color filter can be smoothly changed. In other words, when the first laser is irradiated on the color filter, the color filter forms a gap near the glass of the color filter, and the 10 color filter formed with the gap is easily changed by the laser. Characteristics of physical properties (transparency). When a gap is formed in the color filter, the second laser is used to reduce the light transmittance of the color filter (S3). When the second laser is irradiated onto a color light-emitting sheet formed by a gap, the physical properties of the color light-emitting sheet are changed. At this time, the light transmittance of the color filter - 15 light sheet is rapidly lowered. As described above, in order to repair the liquid crystal display panel, a first laser for forming a gap between the color filters and a second laser for changing the physical properties of the color filter having the gap are required. Thus, a repairing apparatus for a liquid crystal display panel capable of generating a first laser and a second laser will be described with reference to Fig. 5A. Fig. 5A is a block diagram showing a repairing device 40 of a liquid crystal display panel according to an embodiment of the present invention. The repair device 40 for the liquid crystal display panel includes a first laser generator 41, a second laser generator 42, and a laser transmission path 43. The first laser generator 41 generates a first laser 44 for forming a gap between the color chips included in the solar cell 47 of the liquid crystal display panel 12 200827819 46 in the vicinity of the color core glass. In order to minimize the damage of other parts of the liquid crystal display panel during the process of forming the gap between the color filter 'slabs, it is necessary to concentrate the energy of the third laser to be 5 in the portion where the gap is formed. For this reason, the wavelength of the short shot is required. After using a laser of various wavelengths to form a gap in a color filter, it was confirmed that a fine-wavelength laser showed excellent performance. On the other hand, a 532 fine-wavelength laser can also form a gap in the color filter. 10 materials, from the experimental results can be found in the first! When a laser uses a nanosecond laser, it can smoothly form a gap in the color pupil. This is because the crystal lattice of the color filter f is carried out in nanoseconds. When the nanosecond laser is produced, the color and the color filter are resonated, and the color filter can be smoothly formed in the gap. To produce a laser of this nature, the i-th laser generator can use a 1064 nm wavelength nanosecond pulsed laser. The 355 fine-wavelength pulsed laser is obtained from the third harmonic of the nanosecond pulsed laser with a wavelength of l〇64nm. Similarly, a 532-wavelength pulsed laser is obtained from a second spectral wave of a nanosecond pulsed laser having a wavelength of 64 nm. 20 ^ The test results show that the gap size of the color light film is about 〇·4~〇·8μιη, which has less influence on other parts of the liquid crystal display panel, and the color filter can be smoothly filtered by the second laser. The physical properties of the light sheet change. The second laser generator 42 can generate a second laser # which can reduce the light transmittance of the color filter formed by the gap. 13 200827819 The second laser is used to change the physical properties of the color filter formed by the existing gap, so that a laser with a longer wavelength than the first laser can be used. The experimental results show that when the wavelength of the second laser is in the range of about 4 〇〇 to 49 〇 nm, the physical properties of the color filter formed by the gap are relatively easy to change, and the other parts of the liquid crystal display panel are displayed. Less impact. Brother 2 can use femtosecond pulsed lasers or continuous lasers. The physical properties of the color filter when using a 450nm femtosecond pulsed laser during the experiment

Usually, the time required for the lattice vibration of the molecule is in nanosecond units, whereby the physical properties of the color filter can be smoothly exhibited when using a femtosecond laser that concentrates energy in a very short period of time. 15 On the other hand, in a continuous laser generator, a photodiode laser generator that produces a continuous laser of 408 (±8) nm or a photodiode laser generator that produces a continuous laser of 446 nm is used. In the case of the color filter, the physical properties of the color filter are excellent. Fig. 5B is a perspective view showing an example of a repair device for a liquid crystal display panel. The laser and optical sections (corresponding to 40 of Fig. 5A) are movable in the γ-axis direction, and the stage mounted on the liquid crystal display panel (corresponding to 46 of Fig. 5A) is movable in the X-axis direction. In this way, the laser, the optics and the stage can move relative to each other so that the laser corresponds to the unit cell to be repaired. 14 200827819 The Laser and Optics section contains a first laser generator (corresponding to 41 of Figure 5A) that produces a laser for forming a gap in a color filter, which produces a physical H-quality for the color filter. The second laser generator of the changing laser (corresponding to 42 of Fig. 5A) and the laser transmitting path from the laser of the laser generator to the laser cell of the fatigue cell (corresponding to 5A® 43). Fig. 5C is a view showing an example of a laser and an optical portion in the repairing apparatus for realizing the liquid crystal display panel of Fig. 5B. The laser and optics contain laser generation and laser propagation paths. The laser transmission path includes a collimator that improves laser straightness, an attenuator with adjustable 10-section laser output, a lens, a beam, a beam splitter, and a mirror. To achieve the object of the present invention, a laser generator for changing the physical properties of the color illuminator and a ray for transmitting the laser generated by the laser generator to the color filter of the plague cell can be provided. Shoot the path. Therefore, the laser and optical portion shown in Fig. 5C is only an example, and the arrangement of the attenuator, the lens, the beam, the beam splitter, and the mirror can be changed. In addition, the aforementioned optical elements may be deleted or added as needed. Figs. 6A and 6B are cross-sectional views showing a state in which a color filter is formed into a gap by an embodiment of the present invention. Fig. 6A is a photograph showing a case where the first laser beam is irradiated to the color filter of the bright spot cell 2 to form a gap of 46 〇 nm, and Fig. 6B is a photograph of the case where the gap of 736 nm is formed. As shown in these figures, the gap is not formed in the vertical direction but in the horizontal direction. Fig. 7A, Fig. 7B and Fig. 7C are photographs showing the case where the physical properties of the sorrow are changed to reduce the light transmittance of the color filter by one of the inventions. In particular, the 7A, 7B, and 7C images are photographs of a situation in which the physical properties of the gamma wave are changed around the gap when the laser beam is irradiated on the color fascia formed by the gap. - 5 Fig. 7A shows the change in physical properties around the gap when the laser is irradiated with an intensity of 82 degrees, and Fig. 7B shows the change in the physical properties around the gap when the laser is irradiated with an intensity of 84 degrees, On the other hand, when the laser is irradiated with the intensity of 86 degrees, the physical properties around the gap are changed. As a result, as the laser energy increases, the thickness of the portion of the physical property changes increases. Thus, the portion of the physical property change of the color filter can block the light, so that when the physical property change portion has a certain thickness or more, the bright spot cell can become a dark spot cell. However, since there is a possibility that the unit cell becomes bulky, it is important to maintain the physical property change portion at an appropriate thickness. 15 Industrial Applicability According to the present invention, the influence on the adjacent unit cell of the liquid crystal display panel can be minimized by changing the physical properties of the color filter of the germanium unit cell. Further, in the method and apparatus for repairing a liquid crystal display panel, the bright spots are darkened without affecting the adjacent cells, and the yield of the liquid crystal display panel can be effectively improved. Therefore, the industrial applicability of the present invention can be said to be extremely high.
