In recent years, liquid crystal displays have become the focus of next generation high-tech display devices because of low power consumption, high portability, technical intensiveness, and high added value. Active array liquid crystal displays include a switching element for switching the potential applied to each ''pixel', which is highly regarded for its high resolution and advantages for action sheets. Referring to FIG. 1, a liquid crystal panel 500' is constructed in which a color filter substrate 530 (as an upper substrate) and a thin film transistor (TFT) array substrate 51 (as a lower substrate) are bonded to each other face-to-surface The liquid crystal layer 520 is injected therebetween. The liquid crystal panel 500 is driven by switching the tFt that has been connected to thousands of pixels, and the pixels are selected via the address lines to apply the potential to the corresponding pixels. Here, the color filter substrate 530 includes a broken substrate 53 1 , a red/green/blue (Rgb) color filter 532 , a black matrix 533 formed between the color light guide sheets 532 , and a common electrode. An indium tin oxide (ITO) film 535 and an alignment film 536. A polarizing plate 537 is attached to the top of the glass. A thin film transistor array substrate process, a color filter substrate process, and a liquid crystal cell process are performed to fabricate the liquid crystal panel. 5 133*5461 The above-described thin film transistor array substrate process is a process of repeatedly performing deposition, photolithography, and etching on a glass substrate to form a gate line, a material line, a thin film transistor, and a pixel electrode. The color wading substrate process described above is a process for fabricating RGB color filters arranged in a predetermined order on a glass having a black matrix to perform color and form a common electrode. A required indium tin oxide (ITO) film.

The liquid crystal cell process described above enables a process for bonding a thin film transistor array substrate and a color filter substrate such that a gap is maintained between the thin film transistor array substrate and the color filter substrate, and liquid crystal is injected into the gap. * To form a liquid crystal layer one drop filling (ODF) process to uniformly apply liquid crystal to the thin film transistor array substrate, and then connect the thin film transistor array substrate and the color filter substrate to each other. When inspecting such a liquid crystal display, a test pattern is displayed on the liquid crystal panel to test for the presence of defective pixels. When a defective pixel is found, a process for repairing defective pixels is implemented. Liquid crystal defects may include spot defects, line defects (Hne defec〇, and display unevenness (display n〇nunif〇rmity). Point defects are usually due to poor tft, poor element electrodes, or color splicing lines. The line defect is caused by the open circuit between the lines, the short circuit between the lines, the TFT collapse due to static electricity... The connection with the drive circuit is poor. The display of the uneven mark m?疋+ is usually caused by the liquid crystal Cell average, liquid crystal alignment unevenness, TFT distribution in another special position or connection time constant is too the same

1335461 Point defects and line defects are generally caused by poor wiring. In the art, when an open circuit is found, the open circuit is connected only when a short circuit is found, and the short circuit connection is only separated from each other. In addition to the above defects, dust, organic matter, and gold are adsorbed onto the liquid crystal panel during the manufacture of the liquid crystal panel. When adsorbed to an area near the color filter, the pixels of the corresponding slice emit brighter light than the rest of the pixels, and the light-leakage phenomenon» is currently being shot to fix this bright pixel defect. The patent application No. 2006-7229 discloses an alignment film which damages the alignment film to weaken the light of the liquid crystal alignment property, and the technical technique of eliminating the light leakage phenomenon is that the alignment property of the liquid crystal cannot be completely excluded. A lot of time can be done to complete this process. In order to solve the above problem, Korean Patent Application No. 1 proposes to use a femtosecond laser to make a defect image. When a femtosecond laser is used, the pixel can be blackened; however, it is expensive to oscillate to produce a femtosecond laser. SUMMARY OF THE INVENTION Therefore, the present invention has been made in an effort to overcome the above problems, and thus one of them is to provide a repair of a bright pixel deficiency on a display device. In the conventional technology, the impurities are connected to each other, and these impurities are also used as color filters. This is called leak. R&D uses lightning to illuminate the laser and thus reduce it. However, this method, which requires the blackening of 2006-86569, effectively makes the lack of equipment quite obscure. The method of 1335461 can utilize laser to effectively repair bright pixel defects on a display device. The above and other features in accordance with the present invention can be accomplished by providing a method of repairing a bright pixel defect comprising a display device having black matrices, the method comprising: laser filtering a color filter having a bright pixel defect A gap is formed between the color filter and the glass on the light sheet; and the black matrix around the color light sheet is resolved by laser. Preferably, the step of forming the gap is performed when a polarizing plate is not attached to the display device and the color filter is a red (R) region, i.e., a laser having a wavelength of 27 〇 to 55 〇 nm. When the polarizing plate is not attached to the display device and the color filter is a green (G) region, the step of forming the gap is performed by a laser having a wavelength of 270 to 4 80 nm or 600 to 75 nm. . Further, when the polarizing plate is not attached to the display device and the color filter is a blue (B) region, the step of forming the gap is performed by a laser having a wavelength of 270 to 390 nm or 520 to 750 nm. Preferably, the step of forming the gap is performed by a laser having a wavelength of 4 〇〇 to 55 〇 η when a polarizing plate is attached to the display device and the color filter is a red (R) region. When the polarizing plate is attached to the display device and the color light-emitting sheet is a green (G) region, the step of forming the gap is performed by a laser having a wavelength of 4 〇〇 48 〇 ηη or 600 750 750 nm. Further, when a polarizing plate is attached to the display device and the color filter is a blue (B) region, the above-described step of forming a gap is performed with a laser having a wavelength of 520 to 750 nm. Preferably, 'the pulse period of the laser is 100 ns or less' when performing the step of forming the gap and the laser has a repetition frequency of 1335461 between about 1 Hz and 1 kHz. Preferably, when performing the step of forming a gap, when the display has no overcoat layer, the pulse period of the laser is 5 ns or less, and the laser has a range of about 1 Hz to 丨〇〇. The repetition frequency between Hz and the laser power is about 10 mW or less. The teaching method is that the method further includes adjusting the intensity of the laser when performing the step of forming the gap. Preferably, the method further comprises the step of performing the step of forming a gap, the laser used having a flat top shape. Preferably, when the step of forming the gap is performed, the thickness of the gap corresponds to 20% to 90% of the thickness of the color filter. Preferably, 'in performing the step of forming a gap, laser light is created with at least one laser selected from the group consisting of: Ytterbium laser, titanium sapphire laser, Nd: YLF laser, Nd : Glass laser, Nd: Y2 (XV04) laser, Nd: YAG laser, fiber laser and dye laser. Preferably, when the black matrix contains a metal component, the laser pulse period is 50 ns or less in the step of decomposing the black matrix. Preferably, when the polarizing plate is not attached to the display device, the step of decomposing the black matrix is performed by a laser having a wavelength between 270 and 75 nm. Conversely, when a polarizing plate is attached to the display device, the step of decomposing the black matrix is performed with a laser having a wavelength between 400 and 75 nm. Preferably, the step of decomposing the black matrix is performed by the laser used in the step of forming the gap. Preferably, the method further comprises diffusing the decomposed black matrix into 9 1335461

In the gap. In this case, the diffusion has decomposed the black matrix including moving the laser toward the color filter to direct the black moment filter to flow. Preferably, the step of performing the diffusion matrix is performed using a laser that was originally used to decompose the matrix step or the same specifications as the laser. In this case, it is preferred to irradiate the laser with a block shot type laser method or a multi type laser irradiation method. When the step of forming the gap, the step of decomposing, and the step of diffusing the decomposed black matrix are performed, the color intensity is lowered. [Embodiment] Hereinafter, referring to the drawings, a preferred embodiment of the present invention will be described with reference to FIG. 2A. When a color filter is drawn in a z-shape along a laser, the laser is completely irradiated to the confirmed trap. On the color filter 532, a gap G is formed between the color filters 532 (see Fig. 1P, of course, in the thickness direction of the gap G color filter 532 and between the color pupil sheets 531. Next, in Fig. 2B, when the laser light is irradiated onto the black matrix 533 by the laser beam, it is decomposed. The matrix 533 is introduced into the gap G. The step of arranging toward the color ray is The light-dissipating type of the light film of the black matrix of the color filter is broken. The way forward is scanned with bright pixels and the glass 531 can be formed when the color is 5 3 2 and the glass matrix is decomposed. Black 10 1335461

Finally, as shown in FIG. 2C, when the laser is in a Z-shaped black matrix and a color filter, the laser can be completely irradiated on the 533 and the color filter 523 to accelerate the decomposition of the black matrix. The black matrix 5 3 3 is diffused, with the result that the decomposed blacks can be uniformly distributed in the gap G.] The transmittance of the color filter 533 with the black matrix 533 being uniformly distributed in the gap G Will fall. As a result, the color filter transmits light and becomes absorbing light generated from the display source (black; thus, the defective pixel defect can be repaired to cause defective color filter pixels. Unlike the above description, depending on the characteristics of the display, the gap The energy required for G and the energy required to decompose the black matrix 533, the step of forming the gap-solving black matrix can be performed at almost the same time. Referring to FIG. 3, the laser light is an illumination array 533 and a color filter. On 532, the laser is sequentially swept 5 3 3 and the color filter 5 3 2 to repair a bright pixel defect decomposition and diffusion black matrix 5 3 3 and the formation of the gap G is sequentially performed simultaneously. Meanwhile, as described above, according to the present invention, it is necessary to use a laser which can form a gap G in repairing a bright pixel, and it is possible to decompose a black shot and a laser which can diffuse the decomposed black matrix into a gap. In particular, a gap can be formed. The laser of G must be able to satisfy, for example, the type of color filter, whether the display device is attached with a display device or not, and the like. Array 533 and 533 at the same time that the matrix, the color unit 532 can not fc). The film becomes dark when forming between the almost identical steps and points in the black moment to describe the black moment. That is, but almost flawed, the matrix of the mine conditions, polarizing plate, conditional thunder 11 1335461

Shooting can be split by the side ® A to solve the black matrix and make the

In the gap. Because of the black matrix expansion of the knife solution, the common laser is common. In addition, 1 or less of the gap is formed, and the specification of the laser for forming #t will be described in detail. Irradiated by a sputum, such as a color 泸 will interrupt the group, say #慝光片, such as organic ', into the organic matter of the film, it -||JM ife λ *, the connection, -1» The organic film layer is blackened by being separated from and emitting free radicals, clusters, electrons, a neutral atom, molecular bauxite ions and negative ions. Ablation is a process in which organic molecules are decomposed into ions and ions by the coupling molecules of organic matter. However, for this dissociation, it is necessary to absorb higher energy than the energy level of organic matter. Therefore, when forming a gap, it is necessary to irradiate a laser having a low transmittance (i.e., a wavelength having a high absorbance) onto the color filter, and select a wavelength with reference to Fig. 4. For example, when a color filter having a defect is a red (R) region, it can be seen that the wavelength at which the red light is highly absorptive is 550 nm or less. When the red light region is irradiated with a laser having a wavelength above, the transmittance is high, and therefore, the amount of energy, as a result, severely damages the layer under the color filter, including the cover layer 'IT0 layer and the alignment layer. If the color filter layer is destroyed, the liquid crystal will run over the damaged area, resulting in a defect that causes the color filter to be more severe. At the same time, a laser with a wavelength less than 270 nm cannot pass through the glass. Light film. When a laser with a wavelength greater than 750 nm enters the interjection, the photonic layer of the organic film can be dissociated and the wavelength is reached. The bright pixel region of the 5 5 0 nm region requires a large number of diaphragms underneath. Bubbles, the result is Ray Penetrating the 12 1335461 color filter results in the laser not being able to react on the color filter. The conclusion is that when the color filter that needs to form a gap is a red (R) region, it is preferable to irradiate a laser having a wavelength between 270 and 550 nm onto the color filter, thereby effectively A gap is formed in the color filter without damaging the film layer under the color filter.

Accordingly, when such a gap is formed on a color filter, it is necessary to irradiate a laser having a wavelength of low color filter transmittance. For the red (R) region, it is preferred to irradiate a laser having a wavelength between 270 and 550 nm as described above onto the color filter. For the green (G) region, it is preferred to irradiate a laser having a wavelength between 270 and 480 nm or between 600 and 700 nm to the color filter. For the blue (b) region, a laser with a wavelength between 270 and 3 90 nm or between 520 and 750 nm is illuminated. When a polarizing plate is attached to the display device, it is necessary to refer to the light transmittance map of Fig. 5, which shows the light transmittance of the polarizing plate according to the present invention. As shown in Fig. 1, the polarizing plate is attached to the top of the color filter. The laser light used to illuminate must pass through the polarizer.

It can be seen from Fig. 5 that the polarizing plate has a light transmittance of about 50% or less in the visible light range, opaque in the ultraviolet light range, and light transmittance as the wavelength approaches the near-infrared light region. It also increases. For this reason, when it is necessary to form a gap on any of the RGB fluted sheets on the panel to which the polarizing plate is attached, it is preferable to use laser light having a wavelength of 400 nm or more. Therefore, it is necessary to exclude the wavelength in the range of 400 nm or less from the wavelengths obtained in Fig. 4 to form a gap in order to effectively repair the display to which the polarizing plate is attached. Conclusion, when the color filter that wants to form the gap is a red light 13 1335461

For the (R) region, a color filter with a wavelength between 400 and 500 nm can be used. When a color (G) region having a bright pixel defect is irradiated, a laser having a wavelength between 400 and 480 nm is irradiated to illuminate the color filter. When a color filter is a blue (B) region, the color filter can be illuminated using a laser between the inverse nm. Figures 6A to 6C show the irradiation of the laser to the color filter method. Specifically, Figure 6A shows a scanning laser 6B showing a barrier-illuminated laser irradiation method and a J-blocking laser irradiation method. Here, the scanning laser irradiation method is to scan a portion of a region of a light color filter 532 corresponding to a Ray to be irradiated on the entire area of the color filter 523. The radiation method is immediately A laser having a beam shape corresponding to a portion of a color-one region, the entire multi-barrier laser irradiation method is combined with both a scanning and a barrier-illuminated laser irradiation method. That is, the multi-emitter irradiation method is based on the barrier-illuminated laser irradiation method, and the irradiation of the laser is continued according to the scanning-type laser irradiation method. When the laser is irradiated by the above method, whether or not the black matrix is diffused during the separation period, The color filter will drop. Therefore, the bright pixels on the color filter will change as the color filter does not transmit light, but instead turns into light (black light unit) generated by the source. In this way, the repairable color laser can be used to illuminate the light sheet which is a green light-go 600~750 nm bright pixel defect ί long in 520~750 pieces on various side illumination methods, the first 6C picture shows multi-beam shape and a color shot The laser is blocked from the area of the illuminating lightning filter 532 once. Laser irradiation method Blocks the illuminating thunder to illuminate the laser and shoot. The transparency of the color filter strips is dark pixels, which are brightened by 14 135461 pixel defects from the display color filter while diffusing the black matrix.

Referring to Figure 7, it shows the process of lasering several times to form a gap. In detail, when the first laser is irradiated (S 1 ), the Z-axis movement scan is used to find the depth of focus (DOF) corresponding to the 10% thickness of the color filter, and then The color filter is blackened by moving the scan with the XY-axis. When the degree of blackening of the color filter has been confirmed by the charge coupled device (CCD) camera, if it is determined that the gap on the color filter is not sufficient, the Z-axis is scanned to scan and the corresponding color filter is found again. The depth of focus (DOF) of the region of the 0% thickness of the light sheet, followed by the second laser scan (S2) with the XY-axis movement scan. By repeating this step 2 to 4 times, a desired gap can be formed on the color filter. The focal depth (D0P) can be calculated by moving the focal length between the scanner and the scanning lens from the Z-axis and the incident light diameter in the range of 2 microns or less. [Math 1]

DOF = X/2{NAf [Math 2] NA = nsin Θ [Math 3] //# = 1/2_ [Math 4] //# = efl/φ Math 5 can be from Math 3 and Math Formula 4 is derived from both. [Math 5] 15 1335461 ΝΑ = φ/2(βΑ) In the above mathematical formula, ΝΑ 矣 + effective aperture value (λ) represents the wavelength of the laser e·^ represents the effective focal length. It can be confirmed that the diameter of the incident beam is shorter than that of the 'large' laser, and the shallower the DOF. It is also possible to confirm that the focal length of the lens is larger, so the shallower the 'DOF will be. The thickness of the gap is preferably less than 碁 + ^, which is 90% of the large value, preferably between 20% and 40% of the thickness of the color filter. Go

A plurality of gaps can be formed at different thicknesses of the color filter. Referring to Figure 8, there is shown a 'overcoat layer' display to reduce manufacturing costs and simplify the process. At the same time, a cover layer has absorbance as shown in Fig. 9 of the flute Qra. It can be seen from Fig. 9 that there is almost no light transmission below the ultraviolet (uv) envelope, and about 80% of the light in the UV range will be absorbed and only about 20% of the light will penetrate. Therefore, when a gap is formed on the display device without the cover layer, it is necessary to make

The shorter the aperture size (ΝΑ) will be, the different laser specifications will be used when forming a gap on a covered display with overlays. This is because the energy 'generated from the irradiated laser' is absorbed by the cover layer. So for a display without an overlay? The energy of the translucent calender reaches the liquid passage layer, resulting in damage to the liquid crystal layer. A low-energy laser can be used to avoid damage to the liquid crystal layer, but no reaction occurs at this time. Therefore, in considering the above problems, it is necessary to satisfy the conditions of low energy 4 laser and 16 1335461 energy application time. The experimental results show that satisfactory results can be obtained when a laser pulse of 50 ns or less is used, and a repetition frequency is between 1 Hz and 100 Hz, and a power of 10 mW or less is obtained. The specifications of the laser must be selected according to the above conditions before they are used to form the gap. Alternatively, the above-described laser for forming a gap can be used to decompose the black matrix and diffuse the decomposed black matrix into the gap.

However, when a black matrix contains a metal component such as titanium, it is particularly suitable to use a laser having a pulse period of 50 ns or less to effectively decompose the black matrix. The laser emitted from the laser oscillator is a Gaussian laser beam whose energy is concentrated in the central region. When the laser beam passes through a beam shaper or a beam homogenizer, the intensity of the laser beam within a specific range can be uniformized, and as a result, the laser beam can be converted into a flat top shape of an enlarged size. The area of the shot illumination also changes as the shape of the beam changes. This flat top shape can also be changed to a rectangular flat top 300 or a circular flat top 3 0 1 .

A beam shaper or beam homogenizer can also be used to vary the size and intensity of the illuminated laser. The smaller the area of the laser that is illuminated, the longer it takes to completely blacken the pixel. The size of the laser beam can be uniformly converted to increase the speed of blackening, whereby the present invention can be applied to a production line to mass-produce a product. In the organic film layer constituting the liquid crystal panel, Z-axis movement scanning can be utilized to appropriately convert the laser intensity to have a rectangular flat top 300 or a circular flat top 301 to form a gap. According to the present invention, In addition to the above description, the Ray 17 1335461 can be selectively used to effectively repair the bright pixel defect β of a color filter, especially the 'gap can be formed on a color filter with bright pixel defects' to effectively spread Black matrix. In addition, when the color filter is blackened and the black matrix is decomposed and diffused in the defect area of the color film, the bright pixel defect of a display device can be effectively repaired.

In addition, the gap can be effectively formed with or without the attachment of the polarizing plate, the presence or absence of the cover layer, and regardless of the nature of the color filter. The present invention has been described in detail with reference to the particular embodiments thereof. It is to be understood that those skilled in the art can change or modify the embodiment without departing from the scope and spirit of the invention.
