INSTRUCTIONS: [Technology of the invention] The present invention relates to a technique for repairing a liquid crystal display panel, and more specifically, it relates to removing a pixel of a liquid crystal display panel. And a device for implementing the method. BACKGROUND OF THE INVENTION A liquid helium 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 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 unit cell of the liquid crystal display panel comprises a liquid crystal layer 15 which is polarized by controlling a voltage between a thin film transistor (TFT) 15 glass 11 and a color filter (CF) glass 19; for achieving full color r, g, The B color filter π; and the semiconductor circuit layer 12 which can control the degree of polarization of the liquid crystal layer to adjust the light transmittance. Further, the unit cell of the liquid crystal display panel further includes a pixel electrode 13, an alignment film 14, a common electrode 16 and a black matrix 18. 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. The polarized light enters the naked eye through a polarizing plate (not shown) disposed outside the TFT glass and the CF glass 19. At this time, the closer the direction of the polarized light is to the direction perpendicular to the polarizing 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 200829977 . The more smoothly you can pass the polarizer. As a result, the brightness of the unit cell can be adjusted by controlling the degree of polarization of the liquid crystal layer by controlling the voltage applied between the two glass. On the other hand, a color liquid crystal display panel can be realized by using a color filter having a characteristic that light of a specific wavelength can be smoothly penetrated and light of other wavelengths of ~5 lin. 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 makes it impossible for Φ light of its wavelength to penetrate. 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, the dark spot cells can be darkened to a longer extent: the yield of the liquid crystal display panel. For example, when a bright cell 15 cell is completely unacceptable, and one dark cell is allowed to exist, if a liquid crystal display panel having a bright-dot cell replaces the bright cell with a dark cell, the liquid crystal • The display 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 cells caused by the foreign matter, the laser is irradiated on the black matrix to melt the black matrix, and then the substance of the melted black matrix is guided to the foreign matter. In order to darken the cells. However, in the foregoing manner, when the black matrix is melted, the substance of the melted black matrix moves to the normal unit cell adjacent to the unit cell, and there is a serious problem that the normal unit cell is darkened. 200829977 [Patent Literature] 1] Korean Patent Publication No. 2006-0067042 L. 】 Disclosure of the Invention The present inventors have found that it is necessary to minimize the influence on adjacent cells and to darken the bright spot cells. Program. Namely, the present invention is completed by directly irradiating a laser in a light-transmissive region (color filter region) in a unit cell instead of melting a black matrix. 10 However, the way of illuminating the color filter with a laser to darken the 瑕疵 pixel is as explained in Fig. 2. In general, the greater the depth of laser penetration during laser illumination, the more the energy or intensity of the laser decreases, and some degree of laser energy can be transmitted to the deeper layers. Therefore, as shown in Fig. 2, even if the focus 15 of the laser 21 is aligned with the color filter 17, the energy of the - portion is transmitted to the liquid crystal layer 15. Due to the energy transmitted to the liquid crystal layer, there is a possibility that a gas is generated in the liquid crystal layer 15, and such a gas causes a bubble 22 to be generated in the liquid crystal layer. Even if the laser energy cannot be transmitted to the liquid crystal layer, the gas generated in the color filter may intrude into the liquid crystal layer during the laser irradiation process, so that there is a possibility that bubbles are generated. Bubbles generated in the liquid crystal layer can also have a fatal effect on adjacent pixels other than the pixel to be repaired. Further, there is also a case where the entire liquid crystal display panel cannot be used due to the bubble of the liquid crystal layer, and it is necessary to avoid the occurrence of the bubble phenomenon as much as possible. 200829977 In order to prevent the bubble phenomenon as described above, the penetration depth of the laser should be reduced. To this end, the laser wavelength is fulfilled. The laser wavelength is preferably measured from the transparency of the color filter. Fig. 3 is a graph showing the light transmittance characteristics of the color filter. As shown in Fig. 5, each of the color filters is excellent in light transmittance for light in the vicinity of a specific wavelength, but is relatively low in light transmittance at other wavelengths. For example, the B filter 33 is excellent in light transmittance at a wavelength of around 46 〇 nm, the G filter 32 is excellent in light transmittance at a wavelength around 520 nm, and the R filter 31 is fused to 64 〇 11111 or more. Long light transmittance is excellent. 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 laser having a wavelength of a low transmittance of the color filter to improve the energy transmission efficiency. Referring to Fig. 3, a laser is used to vary the physical properties of the R, g, and B filters, preferably using a laser having a wavelength of about 410 nm or less. 15 However, in the process of using a laser with a very short wavelength to make the physical properties of the color filter - changes may occur, other components of the liquid crystal display panel (such as a polarizing plate) may not be used. Therefore, it is best not to continue to use short-wavelength lasers. Here, in the manner in which the laser is directly irradiated on the color filter to repair the liquid crystal display surface 2, the laser is most important in view of the absorbance of the color filter and the bubble phenomenon of the liquid crystal layer, and the present inventors Focusing on this point, and researching on it, it is found that by irradiating the color filter contained in the pixel with a different laser through two stages, the germanium cell can be effectively repaired, and The present invention has been completed. 8 200829977 - The present invention has been made in view of the foregoing problems, and its object is to provide a method and apparatus for minimizing the influence on adjacent cells of a liquid crystal display panel and repairing a germanium cell of a liquid crystal display panel To implement the apparatus of the method. ^ - 5 means for solving the problem, in order to achieve the above object, the repair method of the liquid crystal display panel of the present invention is to irradiate a laser to a color filter included in a pixel of the liquid crystal display panel, so that the color filter is The physical properties are changed, whereby the light transmittance of the aforementioned color φ sheet is lowered. 10 At this time, it is preferable to make the aforementioned laser a continuous laser having a wavelength of about 400 to 490 nm. Further, it is preferable to make the aforementioned laser system a continuous laser having a wavelength of about 440 to 490 legs. Further, it is preferable that the aforementioned laser system has a pulse of a wavelength of about 4 GG to 490 nm. Li Zizi described the laser beam with a wavelength of about 440~490nm. Furthermore, it is preferable to make the aforementioned laser a femtosecond laser having a frequency band of several + MHz. Further, it is preferable that at least one of the irradiation energy, the irradiation time, and the irradiation line width of the laser is irradiated to the color filter. In order to achieve the above object, the repairing device of the liquid crystal display panel of the present invention preferably has a field emission, and the laser system can illuminate the color transfer film included in the castor pixel of the liquid crystal display panel, so that the color transfer film is The physical properties of 200829977 are reduced in light transmission. This ~ month, J Shuo Zhou shot is preferably a continuous laser with a wavelength of ~ ~ Liu. Further, the aforementioned laser is preferably a continuous laser having a wavelength of about 440 to 490 nm. In addition, the 'month ij laser is preferably a pulsed laser having a wavelength of about 4 〇 0 to 49 〇 nm. Further, the A laser is preferably a pulsed laser having a wavelength of about 440 to 490 nm. Moreover, the aforementioned laser is preferably a femtosecond laser having a frequency band of several tens of MHz. The invention has the effect of repairing the liquid crystal display panel of the present invention by the effect of splicing the unit cell on the liquid crystal display panel of 10 Minimized, and the physical properties of the filter and color patches of the unit cell are changed to repair the mad cell. Further, the method and apparatus for repairing a liquid crystal display panel of the present invention can greatly improve the productivity and productivity of the liquid crystal display panel. [Embodiment] -15 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Figure 4 shows a flow chart of the repair process of the liquid crystal display panel of the present invention. To repair the liquid crystal display panel, the bright spot cell (S1) present on the panel of the liquid crystal display 20 is first detected. 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 there is a need to darken the dot-free cell, the liquid crystal display panel is repaired when the bright spot cell is spotted to repair the liquid crystal display panel. Next, the spot cell to be repaired (the germanium cell) is irradiated with a laser to change the physical properties of the color filter included in the cell: 200829977: dot cell, thereby reducing the light transmittance of the color filter. . Thus, in order to repair the liquid crystal display panel, a laser that changes the physical properties of the color filter is required. A repairing apparatus including the liquid crystal display panel of such a laser 5 will be described with reference to Fig. 5A. Fig. 5A is a block diagram showing the repairing apparatus of the liquid crystal display panel of the present invention. The liquid crystal display panel repairing apparatus 100 includes a laser generator 11 and a laser light transmission path 12A. In the process of illuminating the color filter by the laser generated by the laser 110, in order to minimize damage to other portions of the liquid crystal display panel 130, it is necessary to concentrate the laser energy 10 on the germanium cell. Color filter. The laser is irradiated onto the color filter included in the unit cell to change the physical properties of the color filter. Thereby, the color filter can exert the effect of shielding the light emitted from the backlight of the liquid crystal display panel, and dark spots the bright spot cells. At this point, the choice of laser wavelength is very important. As described above, in the method of directly irradiating the laser light onto the color-transparent sheet, it is necessary to take into consideration all of the light absorption rate, the bubble phenomenon of the liquid crystal layer, and the damage of the polarizing plate. In the present invention, it has been found from various experimental results that when the laser wavelength is in the range of about gamma to lye, it is most likely to change the physical properties of the color-changing sheet, and it does not affect other parts of the liquid crystal display panel (eg, Polarizer) has an impact. Further, it has been found from the experimental results that it is preferable to further suppress the damage of the polarizing plate, and the laser wavelength is preferably in the range of about 440 to 490 nm. Thus, the repairing method of the present invention has an effect of ensuring the light-shielding property of the coloring sheet and suppressing generation of bubbles and damage of the polarizing plate. In particular, the present invention can be repaired for a liquid crystal display panel including a polarizing plate by suppressing the damage of the polarizing plate.

In the present invention, when experiments were conducted using continuous lasers, it was found that a continuous laser such as a melon can cause a significant change in the physical properties of the color filter. However, when considering the absorbance of the color filter (refer to Fig. 3), the laser wavelength is such as (5), since the transmittance of the B 10 color filter is significantly increased, and the physical properties of the B color filter are present. The possibility of change is not effectively produced, but in view of the fact that there is no plague for the B color filter, it does not become a big problem in the actual repair process. When a pulsed laser is used, the pulse width is not particularly limited, and not only the nanosecond pulse laser's irradiation of the femtosecond pulse laser but also the transmittance of the color filter is lowered by 15. In the present invention, when using a pulsed laser to carry out an experiment, it is found that a 45 〇 femtosecond pulse yokes a W-shooting 3 to make a color-------- only Zhuang Wang Xian’s change ω 20 in selecting a pulse ray At the time of shooting, in the characteristics of the pulsed laser, the amount of laser light can be concentrated in the laser irradiation region of the color filter, which has the advantage of less influence on the lower portion and the peripheral region of the color filter. In particular, when a femtosecond laser that can concentrate energy in a non-short time is used, the noise around the color filter can be minimized, and the physical properties of the color filter can be revealed. The heat transmission is low, and it takes a lot of time to change the physical properties of the color filter, so it will increase the shortcomings of the repair time, and the high price will increase the disadvantage of the unit price of the repair device. When using continuous lasers, the moonlights of the 2008 2008977 can be transmitted to the periphery by the laser winning boat. Therefore, the filter, the lower layer and the surrounding area are available. However, contrary to the pulsed laser, since the heat of the laser energy can be transmitted, there is an advantage that the repair time can be shortened, and the advantage is cheap. Thus, the repairing method of the present invention can use continuous or pulsed thunder (four), and it is preferable to select the color cut filament, the repair time, and the unit price of the repairing device. 10 15 20 In the actual repair process, the laser is irradiated on the enamel sheet to adjust the irradiation energy, the irradiation time and the illumination line width of the laser. The stronger the irradiation energy of the laser, the greater the degree of change in the color filter f. This is known from the fact that the stronger the irradiation energy of the laser, the thicker the thickness of the physical (four) portion of the enamel or the color film. When the thickness of the portion of the (4) (4) change of the color filter is above a predetermined thickness, the shading of the color patch can be confirmed, and the bright spot cell can thereby become the dark spot cell 1. When the thickness is very thick, it must be considered « Color (4), and the possibility of affecting the periphery of the job color m irradiation time is related to the scanning speed of the laser. The slower the scanning speed, the laser energy per (single) (4) (4), and the physical properties of the color filter The degree of change in nature will also increase. The laser's illumination line is wider than the laser's focus«, and the irradiation of the money is more [the county-unit phase is within the Zhao's shot. The laser energy is reduced, and the physical property of the color filter is changed. . When selecting the most suitable conditions for the above three parameters: The shading degree of the sheet is preferably also considered as the bribe time. ~ When irradiating a laser, the area to be illuminated preferably contains the entire area. In other words, Qian Qi did not have a full part of the laser in the whole of Miyazaki, because it can surely ensure that the film is 13 200829977. Of course, even if the laser is not applied to the entire area of the pixel, the color of the color filter can be ensured, and the laser can be irradiated only to the area of the pixel. For example, when two thin film transistors are individually provided for each pixel, repair can be performed even if only a surface corresponding to one thin film transistor is irradiated with laser light. When the laser is irradiated to the entire pixel, the laser irradiation areas can be overlapped with each other. In other words, the entire 瑕疵 pixel is irradiated with a laser having a line width not exceeding a range of several μm, and it is necessary to irradiate it several times. At this time, if the irradiation area is not superimposed to a certain extent to illuminate the laser, 0 cannot contain all the pixels. The repetition of the laser irradiation area of 10 degrees is best determined after considering the repair time. Further, in order to make the shading of the color film more reliable, it is preferable to irradiate in the two directions of the pupil pixel, and in the horizontal (horizontal) and vertical (vertical) directions, which has the disadvantage of increasing the repair time. If the repair time is taken into account, it is better to set the laser only in any direction of the pixel. In the present invention, it has been confirmed that even if the laser is irradiated only 15 in the longitudinal direction of the pupil pixel, the light shielding property of the color filter can be ensured, and it is confirmed that it is compared with when the laser is irradiated in both directions. Reduce the repair time to less than 1/2. The _ 帛 5 Β diagram shows a perspective view of an example of a repair device for realizing a liquid crystal display panel. The laser and optical section (corresponding to 1〇〇 of Figure 5) can be moved in the γ-axis direction, and the stage mounted on the liquid crystal display panel (corresponding to 13〇 of Figure 5) can be in the 20 X-axis direction. mobile. In this way, the laser and optical sections and the stage can move relative to each other so that the laser corresponds to the unit cell to be repaired. 'The laser and optics contain a laser generator that produces a laser that changes the physical properties of the color filter (corresponding to Figure 11 of Figure 5), and is used for 14 200829977, 5 The laser produces a 1 § laser that correctly reaches the laser transmission path of the mad cell (corresponding to 120 of Figure 5A). 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 generators and laser transmission paths. The laser transmission path includes a collimator that improves the straightness of the laser, an attenuator that adjusts the output of the laser, a lens, a beam, a beam splitter, and a mirror. To achieve the object of the present invention, it is only necessary to provide a laser generator for changing the physical properties of the color filter, and a color filter for transmitting the laser generated by the laser generator to the color filter of the unit cell. The laser can communicate 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. Further, the optical element described above may be deleted or added as needed. Industrial Applicability 15 • 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 瑕/疵 unit cell. Moreover, the repair method and apparatus for the liquid crystal display panel can darken the bright spot cells without causing influence on the adjacent cells, thereby effectively improving the yield of the liquid crystal display panel. Therefore, the industrial applicability of the present invention can be said to be extremely high. 20 I: Simple description of the figure 3 The 1st figure shows a cross-sectional view of the cell structure of the liquid crystal display panel.
