The present disclosure relates to the field of manufacturing liquid crystal display devices, and in particular to a rubbing alignment method. The method includes the following steps: providing a transparent substrate with an alignment film on a surface of the transparent substrate, and driving the transparent substrate to move in a first direction; and rubbing in a rolling manner the alignment film on the surface of the transparent substrate through a rubbing roller with a rubbing cloth on a surface of the rubbing roller, during movement of the transparent substrate. When rubbing in the rolling manner the alignment film on the surface of the transparent substrate through the rubbing roller with the rubbing cloth on the surface of the rubbing roller, the rubbing alignment method further includes carding lint on the rubbing cloth using an ultrasonic wave in real time.
Description
technical field [0001] The invention relates to the field of manufacturing liquid crystal display devices, in particular to a rubbing alignment method and a device thereof. Background technique [0002] In the liquid crystal display panel, the strength of the transmitted light is mainly controlled by the liquid crystal in the panel by the electric field. Therefore, the alignment state of the liquid crystal, especially the initial alignment state, becomes particularly important, which mainly depends on the color filter substrate and the It is controlled by an alignment film with an alignment direction on the TFT array substrate, which can arrange the liquid crystal molecules in a certain direction in the unpowered state. [0003] Traditionally, the alignment direction on the alignment film can be obtained by aligning and rubbing the alignment film with a high-speed rotating rubbing cloth. However, the inventors of the present application have found in the course of experimen...
