Problems solved by technology
[0004] During the formation of the alignment groove, the rubbing cloth will generate frictional static electricity when rubbing on the surface of the alignment film, which may short-circuit the TFT substrate, thereby damaging the TFT element, resulting in defects in the TFT substrate and poor quality of the liquid crystal panel
In addition, the frictional static electricity generated during friction will also increase the amount of friction debris. During the friction process, the friction debris is sandwiched between the friction cloth and the substrate, which will cause uneven force on the substrate, resulting in unnecessary scratches, resulting in liquid crystals The display quality of the panel is reduced

Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a rubbing cloth and a rubbing device. Background technique [0002] During the preparation of liquid crystal panels, it is necessary to form alignment grooves on the alignment films of the TFT (ThinFilmTransistor, thin film transistor) substrate and the CF (ColorFilter, color filter) substrate, so that when the TFT substrate and the CF substrate are aligned, and When liquid crystal molecules are injected therein, the liquid crystal molecules can form a pre-tilt angle according to the alignment groove, which facilitates the deflection of the liquid crystal molecules under the action of an electric field. [0003] Generally, a rubbing process is used to form alignment grooves on the alignment film. For example, a rubbing cloth attached to a rubbing roller can be used to quickly rub the surface of the alignment film to form fine alignment grooves on the alignment film...
