Description

Large size TFT-LCD panel cutting device {Cutting apparatus of TFT-LCD panel}

The present invention relates to a large-sized TFT-LCD panel cutting device, and more particularly, to form a groove and a crack for cutting, as well as attaching a TAB to the upper and lower surfaces of the substrate for fixing the substrate through the chuck to separate the panel. It relates to a large-sized TFT-LCD panel cutting device that allows the operation of a single panel cutting device to form grooves and cracks in the lower substrate.

In general, as much attention has been paid to the increase in size and quality of display devices as a medium for transmitting image information, it is noted that various flat panel display devices have been developed and disseminated in place of CRT (Cathode Ray Tube), which has been used until now. same. It is well known that the liquid crystal display, which is one of the flat panel display devices, has been developed to a level higher than the CRT in terms of color of image quality.

A general manufacturing process of a liquid crystal display panel (LCD) constituting the liquid crystal display device as described above is as follows. First, as an overview, one pixel (comprising three subpixels R, G, and B) of a TFT-LCD panel is as fine as about 0.3 mm in width. Of course, the TFT (Thin Film Transistor) that fits in it is smaller. What's more, the resolution is 1600 x 1200, which means that the number of pixels is 1.19 million. If you consider each sub-pixel, you need 3 times (R, G, B), so you need 576 million TFTs. Therefore, a semiconductor level process is required as a process that requires high precision of the entire process itself.

Meanwhile, TFT-LCD panel manufacturing process is divided into TFT process, color filter (CF) process, cell process, and module process. One panel is made through it, and a panel processed through the cell process is made through a module process, and one TFT-LCD panel is actually made into a monitor or TV.

First, the TFT (Thin Film Trasistor) process is a process of forming a basic electrode, which makes an electrode of each cell as the most basic and essential process. The process sequence includes five steps of gate electrode generation, insulating film and semiconductor film generation, data electrode generation, protective film generation, and pixel electrode generation, but at least one pattern process is required for each step. This pattern process can be called the core of the TFT-LCD panel manufacturing process. Similar pattern processes are required for the CF process as well as the TFT process.

The pattern process as described above is a very precise and complicated process by itself. At least this process is performed several times to make a single TFT-LCD panel. Of course, the same process is not used then, but the schematic process is similar. This pattern process consists of deposition, cleaning, photoresist (PR) coating, exposure, development, etching (PR) process, PR stripping (Strip process), and inspection process. This is necessary.

TFT-LCD, on the other hand, does not emit light on its own like PDP or OLED (organic EL), but controls the brightness of light by controlling the arrangement of liquid crystals in each cell for constant light from the backlight. Since the backlight itself is white light, CF (Color Filter) plays an important role in changing the arrangement of liquid crystals to control the amount of light, but to make R, G, and B to realize color. This CF is located on the top of the TFT-LCD panel and is made through a process separate from the TFT process. The CF process also requires the pattern process described above.

The above-described CF (Color Filter) process requires a BM (Black Matrix) process (deposition, cleaning, PR coating, exposure, development, etching, and peeling pattern process), and pixel-by-pixel process (this pattern process was performed as described above. It is a slightly different process from the process of evaporation and cleaning, and it is possible to apply the photosensitive material with color and go through the process of exposure and development) and ITO process (Indum Tin Oxide: good permeability and conductivity, chemical and thermal stability Excellent transparent electrode material). In addition, some additional processes may be added depending on the type of panel (VA, IPS, TN, etc.).

In addition, the cell process is a process of combining and cutting two glasses made in the CF process and the TFT process into one, and cleaning the CF, TFT, alignment printing, rubbing process, spacer scattering, and bonding. (TFT substrate and CF substrate are precisely bonded), cutting (the bonded substrate is cut and separated into respective panels), liquid crystal injection, and final inspection.

The module process in the above-described manufacturing process is the final step for attaching the polarizing plate, PCB, and backlight unit to the panel made of the cell process as the final process for making the finished product panel. The cleaning, attaching the polarizing plate, attaching the TAB, and defoaming (Autoclave) ), PCB attachment, BLU (Back Light Unit) assembly, and inspection.

Meanwhile, a cutting process of cutting the bonded substrates through a bonding process of precisely bonding the TFT substrate and the CF substrate through the TFT process and the CF process in the cell process of the TFT-LCD panel as described above. In this cutting process, the bonded substrate is cut to separate the substrate on which the TFT substrate and the CF substrate are bonded into a panel, and then one end of the CF substrate for attaching the TAB is cut. At this time, the LCD panel cutting device is an apparatus for cutting one end of the CF substrate for cutting the bonded substrate of the TFT substrate and the CF substrate and for attaching the TAB.

However, since the LCD panel cutting device according to the prior art has a configuration in which a long cutting knife is placed directly on the cutting line of the substrate where the TFT substrate and the CF substrate are bonded, the substrate is directly stressed on the substrate during the cutting operation. The problem is that a small grain progresses. For this reason, there exists a problem that the linearity of a panel will become bad after cutting of a board | substrate.

In addition, the LCD panel cutting device according to the general technique as described above is useful in forming grooves and cracks by supporting a small substrate, because it is configured in a structure that can move the front and rear moving table respectively, but larger than 30 inches (large) There is a limiting problem in supporting the substrate to form grooves and cracks.

Moreover, the LCD panel cutting device according to the prior art is to form grooves and cracks in the bonded substrates to separate the substrates on which the TFT substrates and the CF substrates are bonded into the panel, and the grooves at one end of the CF substrate for attachment of the TAB. And there is a problem that can not work in the work line to form cracks.

The present invention has been made to solve the above-mentioned problems of the prior art, the substrate support device in the state in which one end is bitten by the substrate fixing chuck by configuring the substrate support device configured with the conveyor before and after the linear motor to move back and forth through the linear motor A large TFT-LCD supported by a conveyor configured at the top of the substrate to form grooves and cracks for cutting in the bonded substrates of the TFT substrate tube CF substrate by linear movement of the substrate support device and lateral movement of the crack wheel. The object is to provide a panel cutting device.

Another object of the present invention is a wheel assembly consisting of upper and lower wheel units for forming grooves and cracks on the bonded substrates of TFT and CF and a roller pressing the TFT substrate when forming grooves and cracks at one end of the CF substrate for attaching TAB. Through a single TFT-LCD panel cutting device configured with grooves and cracks at one end of the CF substrate for the formation of grooves and cracks on the upper and lower surfaces of the substrate for separating the TFT substrate and the CF substrate into panels To work simultaneously to form the

Another object of the present invention is to configure the conveyor before and after the upper side of the substrate support device to clock or counter the conveyor when the substrate support device moves forward and backward to form grooves and cracks in the longitudinal direction of the bonded substrate of TFT and CF. It is to minimize the contamination or scratches of the substrate by rotating in a clockwise direction so that interference due to friction between the substrate support device and the substrate that is linearly moved back and forth is not generated.

In addition, the technology according to the present invention can improve the working environment by minimizing the occurrence of glass chips during the formation of grooves and cracks on the substrate where the TFT and CF are bonded, as well as the surface of the grooves and cracks is clean and The present invention provides an LCD panel having excellent linearity.
