A liquid crystal (LC) cell process is included in the overall process of fabricating a TFT_LCD, which is one of the flat display panels. The LC cell process refers to a fabrication-unit 1^: cell process in which a driver circuit is provided to a complete TFT substrate and a color filter substrate such that the unit LC cell can be driven by a signal. LC cell process The characteristics are generally not required to be duplicated when compared to TFT process or color filter process. The overall cell process can be roughly divided into an alignment layer formation process (for aligning LC molecules) and a cell gap formation. Process, liquid crystal injection process, and a polarizing film attachment process. Individual processes have different characteristics, so different processes are required, such as a polymer film forming process, a rubbing process, a vacuum liquid crystal injection process, and the like. Before the unit process, a unit repair process is performed to repair the "unit. However, there is no method in the prior art for repairing bright pixels generated after the unit repair process. Therefore, a method for repairing bright pixels is required. Similarly, A repair process capable of optimizing the process of the whole process should be proposed. [Invention] Therefore, the present invention has been considered for a purpose. Providing a method for repairing a defect rate of a flat display product, as in the case of using a laser, and the method of the present invention, which can reduce one of the bright pixels generated by the unit repair process and convert into a dark pixel, thereby At the same time, this method can optimize the overall repair process, because after converting bright pixels into dark pixels, when the light transmission system is less than a specific value, the laser is not used to convert the bright pixels into In the dark pixel process, a repair process is applied to apply a repair process to red (R), green (G), blue (B), and black (BK) color pixels that are not converted into dark pixels, thereby improving process efficiency. One aspect of the present invention can be achieved by providing a method for repairing a flat panel display panel, comprising: performing a cell repair process; determining whether a brightness defect is caused after the unit repair process Generating: when the brightness defect has been generated, performing a repair process to convert the bright pixel into a dark pixel; determining - light transmission after the repair process Whether it is less than a certain value; and when the light transmission system is less than a specific value, use a dispenser to repair red (r), green (G), blue (B), and black (BK) colors that are not converted into dark pixels. Pixel. Determine whether the brightness defect is generated by the soft,., Wang Wang step, when a defect is generated by a variety of reasons, it is better to determine whether a defect occurs, the multiple reasons are: a liquid crystal Internal particles, w 9-pole open circuit, pixel to data line short circuit, amorphous 矽 (a-Si) residue, pixel pass 延 delay short circuit, TFT with poor characteristics, pixel to pixel short across data line, Hole, S/D open circuit, and pixel 9 no contact 1 rumor short circuit across the gate line. The steps to perform the repair process are performed using lasers. When the light transmission exceeds a certain value, the scent is applied again. The step of performing the repair process is preferably 7 1342073. [Embodiment] A preferred embodiment of a method of repairing the structure having the flat display panel of the present invention will now be described in detail with reference to the accompanying drawings. Figure 2 is a flow chart depicting a method of repairing a flat panel of a flat panel in accordance with an embodiment of the present invention. First, after the "typical unit repair process (S10)" is performed, a determination is made as to whether or not a brightness defect has occurred (S20). When the decision is made, or the luminance defect has been generated, a repair process is performed to convert the bright pixel into a dark pixel (S30). Then, the light transmission 値 is read to determine whether it is smaller than a certain value (S40). When the light transmission 値 is smaller than a certain value, the red (R), green (G), and blue (B) are not converted into dark pixels. And black (Βκ) pixels are converted by using a splitter (S50). Here, a determination as to whether or not a brightness defect has occurred is performed as shown in Figs. 3 and 4. Fig. 3 is a cross-sectional view showing an example of a defect due to particles on a flat display panel, which can be solved by the second circle method. Fig. 4 is a plan view showing an example of various types of defects occurring on a flat display panel, which can be solved by the method of Fig. 2. As shown in Figures 3 and 4, when a defect occurs for one or more reasons, a brightness defect has been determined, including particles in the liquid crystal (1), gate open (2), and pixel-to-data. Line short circuit (3), amorphous germanium residue (4), pixel channel short circuit (5), TFT (6) with poor characteristics, pixel to pixel short across data line (7), data line residual under pixel ( 8), no contact hole (9), S/D open circuit (1〇), pixel to pixel short circuit across the gate line (Η), TFT channel 8 1342073 hole missing (12), high TFT off current (13) , pixel to gate line short circuit (14), and low TFT turn-on current (15). A laser performs a process of converting bright pixels into dark pixels. Meanwhile, when the light transmission 値 exceeds a certain value, it means that an appropriate efficiency has not been reached, and the repair process of converting bright pixels into dark pixels is repeated. A preferred embodiment of a method of repairing a flat panel display panel having a certain configuration in accordance with the present invention will be described in more detail with reference to the accompanying drawings. ® If a detailed explanation of the relevant functions and constructions is made to make the concept of the invention unclear, a detailed explanation will be omitted. The following terms to be interpreted are defined in consideration of the functions of the present invention, which may differ depending on the intention of the user, the operator or the former. Therefore, each noun should be understood based on what is covered by the description of the present invention. First, the present invention relates to the use of a laser to convert a bright pixel generated after a unit repair process into a dark pixel to reduce the defect rate of the product to improve product usability. • Conventional techniques have not provided any process for repairing bright pixels after performing a cell repair process, or after performing a cell repair process and then completing a liquid crystal cell process. Here, the bright pixel represents a sub-pixel of the R, G, and B sub-pixels that form a complete pixel on the color filter, and is displayed on a monitor regardless of the applied voltage. The same color of the color light film Similarly, the bright pixel can even be produced in a black matrix (BK). When the sub-pixel continues to be on (ie, if it continues to be bright 9 1342073 pixels), the problem of monochrome (black or white) quiescent state may occur exclusively. Therefore, the operation mode of the present invention is to make the certain sub-pixels have a constant name (i.e., a dark pixel). That is, the brightness defect generated during the TFT process is converted into darkness for a pixel generated during the attachment process of the TFT and the color light film, and the brightness defect is also converted into a dark image in a unit process. Produced in the following cases. That is, the defect is caused by the generation of foreign matter during the TFT process, the abnormal operation of τρτ, and the short circuit caused by the manual insertion of foreign matter during the process. The case where the brightness defect is generated can be classified as the 3rd and 4th circles (1) Particles inside (2) Gate open circuit (3) Pixel to data line short circuit (4) Amorphous dream (a-Si) residue (5) Pixel channel short circuit

Here, a penetration depth can be adjusted by controlling the intensity of the laser.

Then, as shown in Fig. 7d, the laser system is used to repair the certain sub-pixels' to convert them into dark pixels (7〇6). Therefore, the present invention uses a laser to convert bright pixels generated after the repair process into dark pixels, thereby reducing product defect rate and improving product usability. However, since it takes a long time to convert a bright pixel into a dark pixel using a laser, the process efficiency may be slightly lowered. Therefore, the operation mode of the present invention uses a laser to convert a certain number of bright pixels into a dark image. 11 1342073 converts bright pixels into R, G, B, and BK pixels. More specifically, in performing bright pixel conversion After a certain number of repair processes for dark pixels, the repair process using the laser is terminated, and then the light transmission is read to measure the efficiency. That is, it is determined whether the light transmission 値 is smaller than a certain value. When the light transmission 値 is less than a certain value, it implies that a desired efficiency for the panel has been obtained. Otherwise, the desired efficiency is not achieved. The value—depends on the consumer of the product. When the light transmission 値 is smaller than a certain value, it is determined that a desired rate has been obtained. Therefore, the use of laser conversion to dark pixels is no longer performed. R, G, 8, and 8& pixels that are not converted to dark pixels are converted to unique pixels using a splitter by considering process efficiency. If the light transmission value exceeds the certain value, it is determined that it does not reach the desired efficiency for the panel. Therefore, the repair process of converting a bright pixel into a dark pixel using a laser will be repeated. As described above, in the method of repairing a flat display panel according to the present invention, the bright pixel generated after the unit repair process is converted into a laser using a laser. Dark pixels, which reduce product defect rates and improve product usability. Similarly, when the light transmission 値 is converted to a dark pixel and the light transmission 値 is smaller than a certain value, and the process of converting the bright pixel into a dark pixel by using the laser, the method of the present invention applies a dispenser repair instead. It is converted into R 〇, Β, and ΒΚ pixels of dark pixels to optimize the overall repair process and increase process efficiency. As described above, although the preferred embodiment of the present invention has been disclosed for exemplary purposes, the invention is not limited thereto, but various modifications, variations, and equivalents are available. Therefore, it is not appropriate to change the scope and spirit of the invention to apply it.
