Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0029] An embodiment of the present invention provides a rubbing cloth processing device. The rubbing cloth processing device includes: a carrier and a rubbing substrate, and the rubbing substrate is fixed on the carrier; the rubbing substrate includes a substrate and a plurality of protrusions on the substrate.

[0030] The rubbing cloth treatment equipment provided by the embodiment of the present invention can be used to process the rubbing cloth during the alignment process of the alignment film. The protrusion...

Abstract

An embodiment of the invention discloses a rubbing cloth treatment apparatus and a rubbing alignment apparatus, wherein the rubbing cloth treatment apparatus comprises a carrier and a rubbing baseplate fixed to the carrier; the rubbing baseplate comprises a baseplate and a plurality of protrusions positioned on the baseplate. The technical scheme provided in the embodiment of the invention allows pile knots on rubbing cloth to be opened and piles to be smoothened, foreign matters on the rubbing cloth are removed, and it is also avoided that piles of the rubbing cloth knot and residue in the piles damages an alignment film during generation of a display panel. When piles of the rubbing cloth bifurcate and gather, the rubbing alignment apparatus may comb the piles of the cloth again, and therefore, the pile knots on the rubbing cloth are opened in time and the foreign matters on the piles are removed in time, the piles that are deviated and gathered are combed and returned. It is possible for the display panel to gain uniform alignment, display effect of the display panel is improved, and production yield of the display panel is increased.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of rubbing orientation, and in particular, to a rubbing cloth processing device and a rubbing orientation device. Background technique [0002] The main function of the alignment film alignment process in the liquid crystal display production process is to make the alignment film produce a uniform alignment ability, thereby inducing the alignment of liquid crystal molecules and achieving the purpose of controlling light. During the alignment process of the alignment film, it is necessary to use a rubbing cloth to rub the alignment film on the color filter substrate and the array substrate. The two most important steps in the rubbing process are pre-rubbing aging and rubbing production. [0003] Aging before rubbing refers to the relative frictional movement between the rubbing cloth and the aging substrate, the function is to open the knots of the cloth and return the cloth, and re...
