Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
As shown in Figure 1, it is the conceptual scheme of the uneven method of the elimination LCD friction groove of one embodiment of the invention.
A kind ofly eliminate the uneven method of LCD friction groove, friction is carried out directed by the ito glass substrate 200 of friction roller 100 to coating PI layer, ito glass substrate 200 has PIN (stitch) region 210, electrode pattern region 220 and side 230, comprises the steps:
Step S10, is close to the surface of ito glass substrate 200 by friction roller 100, the axis being parallel of friction roller 100 is in side 230;
Step S20, rotates the surface of friction roller 100 along ito glass substrate 200, with side 230 shape of the axis and ito glass substrate 200 that make friction roller 100 in an angle;
Step S30, pivoting friction roller 100, move linearly ito glass substrate 200 simultaneously, and the rectilinear movement direction of ito glass substrate 200 is vertical with the axis direction of friction roller 100.
Wherein, in step S20, the angle that the axis of friction roller 100 and the side 230 of ito glass substrate 200 are formed is between 10 degree to 20 degree.
Preferably, ito glass substrate 200 moves linearly along the rotation direction of friction roller 100.Move linearly compared to the rotation direction of ito glass substrate 200 against friction roller 100, ito glass substrate 200 can reach better friction effect along the rotation direction rectilinear movement of friction roller 100.
Be noted that friction roller 100 has flannelette 110, friction roller 100 is by the surface contact of flannelette 110 with ito glass substrate 200.In friction orientation process, friction roller 100 runs up towards certain sense of rotation in fixing position with flannelette 110, and electrode pattern region 220 is moved along ito glass substrate 200 traffic direction, and phase mutual friction forms friction groove.
Electrode pattern region 220 electrode is coated with certain thickness PI (Polyimide, polyimide), PIN region 210 only has electrode and is not coated with PI.Because electrode pattern region 220 electrode and PI layer have certain thickness, microcosmic can cause the friction intrusion at corresponding flannelette electrode pattern region 220 and flannelette PIN region 210 place on friction flannelette 110 have seriously inconsistent phenomenon.When the flannelette 110 on friction roller 100 long towards certain sense of rotation high speed rotary grinding time, PIN region 210 and electrode pattern region 220 edge friction groove can be caused to occur depth non-uniform phenomenon, PI tilt angle and PI herein is finally caused to the anchoring energy difference of liquid crystal, to form display uneven bad.
As shown in Figure 2, it is the conceptual scheme of the uneven method of traditional elimination LCD friction groove.The uneven method of traditional elimination LCD friction groove is with the main difference part eliminating the uneven method of LCD friction groove of the present invention: the rectilinear movement direction of the ito glass substrate 300 of the method that traditional elimination LCD friction groove is uneven is not vertical with the axis direction of friction roller 400.
This kind of traditional method, can produce following technical disadvantages:
1, the uneven frequent generation of friction groove, fraction defective is high;
2, process friction groove uneven abnormal time, frequently change friction cloth, material waste is large, and production efficiency is low and cost is high;

4, for preventing the uneven product of friction groove from flowing out, frequent inspection when friction is produced, is needed, and the more difficult control of friction groove inequality, easily undetected.
And the invention provides a kind of uneven method of LCD friction groove of eliminating, realize especially by following scheme:
As shown in Figure 1, the electrode pattern region 220 of ito glass substrate 200 to be rubbed rotates a certain angle, friction roller 100 with flannelette 110 is towards the same angle of same direction rotation electrode area of the pattern 220, the friction track of flannelette 110 at PIN region 210 and electrode pattern region 220 adjacent edges can be changed like this, the flannelette 110 in each place on friction roller 100 can be rubbed to the PIN region 210 not having PI layer and the electrode pattern region 220 having PI layer, the Frotteurism otherness of flannelette electrode pattern region 220 place's flannelette state corresponding on friction flannelette 110 and flannelette PIN region 210 place flannelette is reduced.When the flannelette 110 on friction roller 100 long towards certain sense of rotation high speed rotary grinding time, just the phenomenon that intrusion is inconsistent can not be caused in friction operation, ensure that no matter be center, electrode pattern region 220, or the friction groove near edge, PIN region 210 is even.
Because friction roller 100 and ito glass substrate 200 to be rubbed all rotate same angle towards same direction, after final laminating, on upper and lower two panels electrode pattern, PI layer friction groove angle does not change, so can not impact the visual angle of product.
As shown in Figure 1, this kind of scheme, friction roller 100 is with when the ito glass substrate 200 rubbed turns clockwise, and rubbing intensity and frictional strength all slightly increase; And rubbing intensity and frictional strength slightly reduce when being rotated counterclockwise, but larger impact can not be caused on display effect.
This programme is angularly rotate friction pulley angle and electrode pattern angles of product to be rubbed simultaneously, eliminates LCD friction groove non-uniform phenomenon, enhance productivity and product yield under the principle not affecting product visual angle and quality.
This scheme is simply easy to realize, do not need to increase utility appliance, only need change friction roller angle and treat that frictional product operation angle can eliminate the uneven phenomenon of LCD friction groove, friction front glass can be cancelled and keep in operation, enhance productivity, reduce friction cloth consumption, guarantee product yield and quality.
For eliminating the uneven phenomenon of LCD friction groove further, also can increase peripheral auxiliary electrode, and increase PI on auxiliary electrode block, make flannelette consistent with normal viewing area electrode Frotteurism in friction, also can reach same object.
Above-described embodiment is the present invention's preferably embodiment; but embodiments of the present invention are not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present invention and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
