Description of the Invention: [Technical Field] The present invention relates to a method for repairing defects of a liquid crystal display (LCD), in particular, a black method for eliminating light leakage caused by impurities inside a liquid crystal cell Device and method. [Previous technology] Recently, liquid crystal displays are considered to be the next generation of sophisticated display elements due to their low power consumption, convenient carrying, high technology, and high added value. - Such a liquid crystal display is an active matrix type liquid crystal display device having a switching element capable of switching a voltage applied to each pixel, and has attracted attention due to its high definition and image display function. The liquid crystal display adopts a bidirectional combination of an upper substrate color filter and a lower substrate/substrate transistor (Thin Film Transistor) array substrate, and a dielectric anisotropy is formed therebetween. In the liquid crystal layer structure, a thin film field effect electric u crystal TFT to which hundreds of thousands of pixels are added is switched by an address wiring for pixel selection, and is driven in such a manner as to apply a voltage to the corresponding pixel. In order to manufacture the above liquid crystal display, a thin film field effect transistor TFT array substrate processing, a color light beam substrate processing, and a liquid crystal cell processing are required. The thin film field effect transistor TFT array substrate is repeatedly deposited, photolithographically processed, Processing such as money etching, forming gate wiring, data wiring, thin film field effect transistor, and pixel electrode processing on a glass substrate. The color filter substrate processing is performed by placing a color filter layer of red-green-blue (RGB) which displays colors in a predetermined order on a glass substrate on which a black matrix (black 5 200827821 matrix) is formed, and then using indium tin. An oxide (Indium Tin Oxide, ITO) film forms a common electrode. Further, the liquid crystal cell processing is a process of bonding a thin film field effect transistor TFT array substrate and a color filter array substrate while maintaining a certain gap, and injecting liquid crystal between the slits to form a liquid crystal layer. During the inspection of the liquid crystal display device described above, a test pattern is displayed on the face of the liquid crystal display to determine whether or not there is a non-conforming pixel, and when the defective pixel is found, it is repaired. The failure of the liquid crystal display can be classified into point defects, line defects, and display unevenness, in which the TFT element, the pixel electrode H is inferior to the wiring of the photoreceptor, and the like; the open circuit, the short circuit, the TFT damage caused by the static electricity, Driving circuits and poor contact can cause line defects; unevenness of cell thickness, unevenness of liquid crystal orientation, diffusion of TFT at a specific point, or relatively high transient time constant can cause display unevenness. Among them, the 'point defect and the line defect are caused by the failure of the wiring. In the past, if the wiring of the open circuit (Gpen) was found, the open portion was connected, and if there was a short circuit, the relevant wiring was opened. In addition, there are some pixel units that emit special bright light. The spoon sees s s, and it is easy to detect the light leakage phenomenon at such a specific point. It is found that the liquid crystal display which is a light phenomenon is classified into a non-conforming product. However, the open circuit or the short circuit of the drain wiring is irrelevant, and the conventional technique of processing the wiring cannot solve the problem. In the process of liquid crystal display, impurities such as dust 'organic matter or impurities such as ruthenium' are adsorbed, such as being adsorbed on a color light-emitting sheet attached to 200827821. The ''pixel' unit is driven to emit more normal pixel units than when it is driven. The more party's light's brightness-inferior pixels that cause the formation of light leakage may be classified as substandard products during the display inspection process. Research work is being carried out using lasers to eliminate such impurities. Japanese Patent No. 2006-72229 discloses a technique of irradiating a laser to an alignment film to change the alignment characteristics of the liquid crystal, thereby reducing the transmittance of light to the liquid crystal, and eliminating the light leakage phenomenon. But these methods do not completely eliminate the permutation characteristics' and the program takes more time. Further, Korean Patent No. 2006_65134 discloses a repairing technique of irradiating a laser onto a facing film to make it translucent. The above-mentioned laser uses a neodymium YAG laser, a diode, a carbon dioxide (c〇2) laser, and the like. However, in the above method, a laser having a nanosecond pulse width is generally used, and when it is irradiated onto the substrate to be repaired, the range of the substrate is damaged due to thermal diffusion, and the liquid crystal substrate becomes unsatisfactory. . In particular, when the organic layer is hazing, the area subjected to laser irradiation is less than the area of the organic material, which requires a longer processing time and is not suitable for mass production. In the factory production line.

Selecting a laser oscillator surrounded by the wavelength (10) absorbed by the film according to the position of the defective pixel and the film to be blackened, and the laser beam oscillated by the selected laser oscillator passes through the beam adjusting unit 104, 105, 106 adjusts its angle, intensity, and polarization, and the beam forming unit 1G7, (10), and (10) smoothes the beam profile to the same day, and adjusts the beam size to coincide with the position to be blackened. In addition, through the two semi-transparent mirrors 11 and Sichuan, each of the laser beams is used to form a beam. ϋ By the above method, the energy distribution of the irradiated light beam is uniform, and the size can be adjusted. Therefore, the light beam can be scanned to the portion to be blackened to perform blackening, and (4) the large light beam can also be adjusted. Irradiation of the whole body "b丨〇ck shot" (the way in which only the primary beam is irradiated to the portion to be blackened). The first half mirror 110 transmits the laser 1红色1 in the red wavelength range, 12 200827821 Laser 102 reflecting the near-infrared range; the second half-transparent mirror 彳11 transmits the laser in the red wavelength range 1 01 and the laser in the near-infrared range 1 02, reflecting the laser in the green wavelength range 1 03. (a) and (b) of the three figures are graphs of transmission and reflection according to the wavelengths of the first half mirror 11 分别, respectively, and the sum of the fourth figure ((9) is according to the second half mirror 111, respectively. The transmission and reflection curves of the wavelengths. That is, the transmission wavelengths of the first half mirrors and the second half mirrors are different, so the design is based on the characteristics of the laser wavelengths. Coating. The first half of the mirror is 11 〇 and the second The transmission and reflection characteristics of the transflective mirror can be varied according to the characteristics of the laser oscillator and the above-mentioned half mirror. As described above, the beam adjusting units 1〇4, 1〇5, 1〇6 will The oscillating laser beam is adjusted to a state suitable for blackening. If the output laser intensity is too large, it will damage other fingers than the film to be blackened, and the entire liquid crystal display will become waste. After being adjusted to an appropriate state, the laser beam forming unit 1〇7, 1〇8, 1〇9 is further rotated by the beam transmitting unit (2) by the half mirror 11G, and then incident. Moving to the scanning unit 131 by the Z-axis. The laser beam is condensed by the scanner 131 and the scanning mirror 135, and then irradiated onto the liquid crystal display (10). While the laser beam is being irradiated, the scanning unit 134 is moved by the χ γ axis to move the required size and The shape of the laser beam 'is blackened the film. The blackening of the enamel film which constitutes the liquid crystal display 14 from 1 匕 ' ' ' ' ' ' ' ' ' ' ' 扫描 扫描 135 135 135 135 扫描 135 135 135 扫描 扫描Strongly seeing the processed image reflected to the camera The image in the machine connecting device 132 is half-transparent into the continuous lens 132-1 and transmitted to the ccd 13 200827821 camera 133 for real-time monitoring. At this time, the camera connecting device 1 32 can be inserted for use as needed. A relay lens (not shown) that enlarges or reduces the image or a Cut-Offfiiter (not shown) that eliminates a certain wavelength of wavelength for obtaining a clear image. An enlarged view of the scanning mirror 1 35 and the illumination source 136. As shown, the illumination source 136 is looped around the scanning mirror 135. The illumination source 136 includes a plurality of LED illuminations 137. When the processed light source 136 transmits the processed image to the CCD camera 133 by the scanning mirror 135, it is concentrated to a size slightly larger than the processing range to supplement the insufficient light. For example, if you want to blacken one of the RGB pixels of the LED board color filter, use the laser that absorbs the widest wavelength of the spectrum. In order to eliminate each pixel, the laser oscillator can be selectively oscillated and outputted inside the laser oscillator constructed as described above, so that the pixel can be blackened with high efficiency. The laser oscillation unit 1 选择 selects a wavelength according to the presence or absence of the polarizing film 280 on the surface of the color filter glass 260a to be processed, and when the polarizing film 280 is pasted, it is preferable to use a red wavelength of 〇1. A laser having a green wavelength of 103 or a near-infrared wavelength of 102 is preferably a laser having a red wavelength of 101, a green wavelength of 1 〇 3, and a blue wavelength of 1 〇 2 -1 before being attached to the polarizing film, that is, According to the presence or absence of a polarizing film, a laser having a cyan wavelength of 102-1 replaces a laser having a near-infrared wavelength of 1 〇 2 . More commonly used is the use of a polarizing film 28 on the liquid crystal display for blackening, and is also suitable for use in finished products. The processing can be carried out in a state in which the polarizing film 280 is provided, and the processing can be carried out under the unpolarized film 28 under the condition of 200827821. However, the shorter the wavelength of 疋, the higher the absorbance in the material. If there is no polarizing film 28Q _, instead of the near-infrared wavelength 1 G2, the laser with a cyan wavelength of 1 〇 2_1 is better. The seventh figure is a graph of the transmittance of the color filter in the liquid crystal display. To blacken one of RGB, refer to the above graph. For example, to blacken a wavelength range of 530 nm - green wavelength - if a laser using a green wavelength is transmitted, blackening cannot be performed.

The k-picture shows that the transmittance in the visible light band is 5% or less, and the wavelength in the ultraviolet (UV) band is not transmitted at all, and the transmittance is increased as it approaches the near-infrared range. Therefore, in order to blacken one of the rgbs of the pixel having the polarizing film, it is preferable to use a laser in the near ultraviolet range. For example, if one pixel of the color grading sheet W RGB of the blackened LCD panel is used, it is necessary to use a laser that absorbs the widest wavelength of the spectrum of each pixel. In order to eliminate the 'pixels', the lasers configured as described above can selectively oscillate the respective lasers for the respective pixels, so that the pixels can be blackened with high efficiency. Example: If you want to blacken the blue (8) band of the color filter in the liquid crystal display, == wavelength of the laser; if you want to blacken the red (... skin segment, you need to use near, νί long laser; if you want In the blackened green (G) band, it is necessary to use a laser with a near-infrared wavelength. According to the specific situation, if you want to love the media, the color band of the color filter in the black liquid crystal display device is It is necessary to oscillate the yellow wavelengths of 汝 and ..., (greater than or equal to the yellow wave $ π Η, $ wavelength below the wavelength of the laser; if you want ...,,, the color band, you must revitalize the old year &;, g, 撖 street out of the green wavelength below or near-infrared wavelength 15 200827821 or more laser; if you want to blacken the green band, it is necessary to oscillate a laser below the cyan wavelength or above the yellow wavelength. The organic matter constituting the film undergoes intermolecular bond cleavage, releasing plasma including neutral atoms, molecules, positive and negative ions, free radicals, ion clusters (CLUSTER), electrons and photons (PHOTON), and then burned (ABLA Ding)丨〇N) Blackening. Burning # (ABLATION) is The phenomenon of the dissociation between the molecules constituting the organic molecules becomes a phenomenon of molecules, ions, etc., and the organic matter absorbs energy above the energy level for such dissociation. The ninth figure is a graph of the outline of the laser beam embodying the present invention. The laser irradiated by the oscillator is Gaussian (the state energy is concentrated in the middle range. With such a laser: beam formation 2 108 1 (beam shaper or homogenizer), the intensity of the laser beam is m in a certain range, and is converted into The contour of the enlarged flat top 'the illumination area of the laser along with the beam profile also changes at the same time. At this time, it can be changed to a four-corner flat top 3〇〇 or a round flat top form period. According to an embodiment of the present invention The beam forming unit and the beam adjustment adjust the size and intensity of the irradiated laser beam, and the irradiated laser light-shooting is small. The longer it takes to blacken the entire majority of the pixels, the larger the size of the upper beam can be. It is suitable for production lines that are mass-produced. It is transformed into a laser with a 301 angle flat top 3〇0 or a round flat top shape, and the RGB material in multiple films is moved through the Z-axis. The liquid crystal display is blackened to the required thickness. Figure 10 shows the focus convergence range designed according to the thickness of the film to be blackened to the desired thickness of 16 200827821: film removal and blackening treatment (De_ A schematic diagram of the coffee s, D0F), that is, the process of removing the focal length after the thin mold of the required thickness is removed. The z-axis moving scanning unit 131 is used to align the range of the (D) of the thickness of the D element, and then χγ Axis movement scanning list:: '亍,., and CCD camera to confirm the degree of blackening. When blackening is insufficient, the position of the reel movement scanning unit 131 is moved again, 胄D〇F and a range equivalent to 20% of the pixel thickness. After alignment, the Leo χ γ axis moves the scan: =134 to perform the division. After repeated elimination for 2 to 4 times, the blackening reaches a satisfactory degree of privacy and the blackening is terminated. Prepare for the next step. The eleventh figure is a flow chart for performing the blackening process by moving the focus distance in accordance with the above steps. As shown in the figure, the laser light S1 is initially irradiated, and the blackening S20 of 1% is completed. After confirming the degree of blackening S30, it is judged whether or not the blackening degree s4〇 is satisfied. If the blackening reaches the requirement, the blackening S5 is terminated. Upon reaching the requirement, the z-axis moves the S60 focal length to re-illuminate the laser for blackening. The focus convergence range is not more than 1 pm, and is calculated based on the focal length of the Z-axis moving scanning unit 1 31 and the scanning mirror 1 35 and the diameter of the incident beam. Mathematical expression 1 DOF = ^/2(NA)2 Mathematical expression 2 NA = nsin0 Mathematical expression 3 17 200827821 f/# = 1 / 2(NA) Shirt type 4 f/# = efl Ιφ Using the above mathematical formula 3 and mathematical formula 4 can be derived from Mathematical Formula 5. Argon #式5 NA =0/2(efl) In the above mathematical formula, where NA (numerical aperture) is a digital aperture ’, (lambda) is the wavelength of the laser, and ef丨 is the focal length. "T knows that the larger the diameter of the incident beam, the shorter the laser wavelength, the narrower the focus convergence range. If the focal length ef| of the lens (丨ens) is short, the digital aperture will become larger, and the focal convergence range (DOF) will be narrower. . In the present invention, a focus convergence range (D〇F) of 1 " m or less is produced, and a large-diameter scanning mirror 1 35 is used, and an optical apparatus corresponding thereto is designed. The color light-passing sheet 24 使用 used for the liquid crystal display preferably has a thickness of 20 to 40%, preferably not more than 9% by weight, so that light leakage does not occur in the field of view of the night display. If the blackening treatment is to be carried out at a degree of less than 2%, it is impossible to carry out 1GQ% ::: excessive blackening may damage the film of the lower layer. In addition, it plays an important role in properly: blackening the film's laser energy as much as possible. That is, the rounding energy of the concertment adjusts the blackening thickness. Tian Twelve. a, twelve b, twelve C picture is a blackening process of the film of the pixel of the blackening image according to the present invention, and scanning can be performed (the single f adjusts the beam size of the laser pair to generate light leakage) a picture 18 200827821 Multiple times of multi-block Sh0t (block shot (10th-6th) or whole block), the laser is irradiated to the way It means that the block shot method is a method of irradiating only one i-speed to the part that is to be irradiated, and is also called the range (sc〇pe); -bl(5cksh()t) is a combination of the scanning method and the whole piece of the radiative radiation method 'continuous irradiation with the scanning side C shot while performing the irradiation. For example, a liquid crystal display having a computer screen size has a far-reaching area of pixels, and is converted into a pixel size by the beam formation. When the pixel area of the Yachi liquid crystal display is the same, a laser (4) ock shot is used. ) The entire area of the pixel can be blackened (p.: c). In another example, the pixel of a liquid crystal display for a 30-inch large-sized television set is hundreds of thousands of square micrometers (_2), and the entire area of the film corresponding to the pixel cannot be blackened only by the laser irradiation. At this time, by scanning in the "Z" shape on the entire surface of the film (12th 3rd figure) or by multiple pieces of radiation (mum she ck sh〇t) (twelfth c picture) Laser exposure. Figure 13 is a block diagram of the blackening device according to another embodiment of the present invention, comprising: a plurality of laser oscillators; and a beam adjusting unit that adjusts an output intensity of a beam oscillated by the laser oscillator And including: a beam forming unit for changing the contour of the above-mentioned laser beam and a laser detecting unit 100 for selecting a half mirror for transmitting or reflecting the laser beam in 200827821; ^ 70 for controlling the above-described laser oscillation unit 100 An image of the irradiated laser beam and an imaged focused optical unit 400. ~ Here, the description of the overlapping portion with the first figure is omitted. The optical unit 400 includes a direction conversion mirror 401 for guiding a laser beam output from the above-described laser oscillation unit 1 to a liquid crystal display to be blackened. In the present embodiment, only one direction conversion mirror 4〇1 is displayed, but the number and position of the above-described direction conversion mirror 401 can be variously changed depending on the positions of the laser oscillation unit 1〇〇 and the target object 14〇. The above-described direction conversion mirror 401 is to reflect the laser beams of all wavelengths oscillated from the laser oscillator, and is therefore designed to be used over a wide range of wavelengths. The plating shown in the sixth figure can be equally applied to this embodiment. Further, the optical unit further includes a focus sensor 415 and a focus lens (419) for automatically focusing a film to be blackened in a plurality of films. a slit (s I it) for adjusting the laser beam 41 3; a slit (s丨it) illumination 41 2 for determining the size and position of the slit (s I it ); reflecting the slit (s I It is a slit half mirror 411 for illumination; two half mirrors 414, 417 for confirming pixels of unacceptable brightness; a CCD camera 416 and a light source 418. After confirming the position of the luminance defective pixel, the focus of the laser is adjusted by the focus sensor and the focus lens to the film to be blackened among the plurality of films. After the focus sensor 41 5 and the light source 41 8 are irradiated to a specific one of the plurality of films, the re-reflected light is sensed by a splitter. 20 200827821 If the focus of the image is not allowed, the focus sensing stomach 415 controls the focus lens 419 'up and down to get a clear image and instantly pass the cCD camera. The "CCD camera determines the position of the luminance defective pixel and the black film to be blacked out". According to the type, a laser oscillator suitable for blackening is activated, 1〇2, 1〇3. The beam adjusting units 104, 1〇5, 1〇6 adjust the output laser to a state suitable for blackening processing. The laser beam adjusted to an appropriate state is irradiated to the liquid crystal display 14 through the focus lens 419 after passing through the beam forming units 107, 108, 1〇9 and then adjusting the size thereof via the slit (sm) 4i3. The process of blackening the film constituting the liquid crystal display 140 can be immediately monitored by the CCD camera 41.
