Polishing roller array of multi-unit structure for display panel cleaning device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology for cleaning display panels, and more particularly, to continuously remove foreign substances on upper and lower surfaces of a display panel while moving display panels such as FPD panels including TFT-LCD panels and similar glass in one direction. Display panel cleaning device which improves the cleaning effect of the display panel by multi-arranging the polishing roller unit for polishing the surface of the display panel in the configuration of the display panel cleaning device that is removed by The present invention relates to a polishing roller unit having a multi-array structure for use.

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. One of the flat panel display devices, the liquid crystal display device has developed far beyond the CRT in terms of image quality and color, and has become a main product dominating the world market.

The general manufacturing process of the general TFT-LCD panel (Thin Film Transistor Liquid Crystal Display Panel) 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. Furthermore, to reach a resolution of 1600 x 1200, the number of pixels is 1.19 million, which requires 3 times (R, G, B), considering each sub-pixel, and requires 576 million TFTs. Therefore, a semiconductor level process is required as a process that requires high precision of the entire process itself.

Meanwhile, the manufacturing process of the TFT-LCD panel as described above is largely divided into a TFT process, a color filter (CF) process, a cell process, and a module process, and has two glasses that have undergone a TFT process and a CF process. One panel is made through a cell process, and a panel processed through a cell process is made through a module process, and a TFT-LCD panel that is actually used for a monitor or a TV is made.

First, the TFT (Thin Film Transistor) process is a process of forming a basic electrode, which makes the electrode of each cell 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, the amount of light is controlled by changing the arrangement of liquid crystals, but CF (Color Filter) plays an important role in making 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 without the need for the deposition and cleaning process, by applying a color-sensitive photosensitive material to the process of exposure and development) and the ITO process (Indium 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 and TFT, polyamide 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 of the above-described TFT-LCD panel manufacturing process is a final step for attaching a polarizing plate, a PCB, a backlight unit, etc. to a panel made of a cell process as a final process for making a finished product panel. Attachment, defoaming (autoclave), PCB attachment, BLU (Back Light Unit) assembly, inspection.

Meanwhile, in the process of manufacturing a TFT-LCD panel through a TFT process, a color filter (CF) process, a cell process, and a module process as described above, a process of removing foreign substances and particles on glass or a panel is performed in each process. This prevents defects such as defective pixels of the TFT-LCD panel by cleaning the glass or panel during each process.
