Problems solved by technology
Once this kind of frictional copying pattern occurs, it will directly affect the display quality of the LCD, and even make it scrapped.
At the same time, the friction copy pattern is caused by the limitation of the equipment in the friction industry and the particularity of the design. It is difficult to eliminate it. The only way to improve it is to change the typesetting direction and modify the friction angle. However, if targeted modifications are made, it will Change the viewing angle of LCD and reduce the utilization rate of ITO glass substrate

Embodiment Construction
[0023] The principles and features of the present invention will be described below with reference to the accompanying drawings, and the exemplary examples are intended to be construed as they are intended to limit the scope of the invention.
[0024] A method for eliminating rubbing friction LCD replication of patterns, such as figure 2 , One end of the ITO glass substrate 2 having the marking portion 3, numerals 3 mark information indicating section.
[0025] Specifically, the marker portion 3 are disposed at an edge of one side of the ITO glass substrate 2, low-grade type LCD section 3 may be labeled PI / TOP alignment mark, the alignment mark silk screen, bonding alignment mark, mark cutting, high-grade a plurality of LCD type alignment mark and the IC design and the like. 3 by unit marks TIO TIO layer plated on the glass substrate obtained by etching, and forming a concavo-convex structure on the stepped surface of the ITO glass substrate 2. These differences in height of une...

The invention discloses an LCD rubbing method for eliminating rubbing and copying lines. The ITO glass substrate coated with a PI layer is rubbed and oriented by a wool wheel. One end of the ITO glass substrate has a marking part, and the marking part is used to represent marking information, including the following steps : S1, move the ITO glass substrate horizontally to the right or left, so that the end with the marked part on the ITO glass substrate is away from the hair wheel; S2, move the ITO glass substrate upwards so that the surface to be rubbed is tangent to the rotation direction of the hair wheel; S3 1. Turn the hair wheel, and at the same time move the ITO glass substrate linearly to the left or right along the direction close to the hair wheel to make the ITO glass substrate and the hair wheel contact, and rub the groove on the ITO glass substrate through the hair wheel. The invention eliminates the rubbing reproduction lines generated in the rubbing process while keeping the viewing angle of the LCD unchanged, improving the display quality of the LCD and increasing the production yield of the LCD.
Description
Technical field [0001] The present invention relates to emergency monitoring technical field, particularly relates to a method for eliminating rubbing friction LCD pattern of replication. Background technique [0002] LCD production, the need for PI layer coated ITO glass substrate rubbing orientation. Friction is milled grooves in a certain direction in the PI layer, the consistency of the liquid crystal alignment direction can be milled. Current processes generally use rubbing cloth hair sticky glass friction wheel, so that PI alignment layer to give a dense and uniform grooves, so that the ability of the liquid crystal molecular orientation. [0003] Current LCD equipment suppliers in order to make the friction device has higher accuracy and stability, the hair is generally regarded as a fixed wheel 30 degrees, using only the rotary platform to meet the needs of an LCD rubbing process, while the glass edge irregularities are present design, this will have two types of friction...
