What particularly point out is in the present embodiment, to form the coating route that intersects between the two adjacent default liquid crystal overlay areas, therefore, during the cutting liquid crystal cell, cut in X position, the point of crossing of C-X-D and Q-X-R, cause the situation of leaking liquid crystal to avoid the frame adhesive pattern to disconnect.
Fig. 6 shows the synoptic diagram of the coating route of liquid crystal panel frame adhesive coating process the 3rd embodiment of the present invention.Default liquid crystal overlay area is rectangle, and default liquid crystal overlay area is arranged in rows.Only through once, the coating route of frame adhesive is A-B-C-D-E-F-G-H-I-J-K-L-M to the injecting glue device on each limit of default liquid crystal overlay area, and only through once, wherein A is starting point on each limit of default liquid crystal overlay area, and M is terminal point.Preferably, starting point A and terminal point M are outside the frame adhesive pattern of closure.Certainly, starting point A and terminal point M also can select one outside the frame adhesive pattern of closure.Arbitrarily continuously the coating route on the both sides of coating once turns to mostly occurring, and the steering angle that turns to is 90 °, and the both sides of coating comprise both sides that same default liquid crystal overlay area is continuous and adjacent adjacent both sides, two default liquid crystal overlay areas continuously arbitrarily.Compare first embodiment, continuously the default liquid crystal overlay area of coating while arrive another default liquid crystal overlay area the time, the angle that turns to is 90 °, 180 ° steering angle can not occur, therefore the radius r of corner can be bigger, therefore the vibrations that can alleviate board equally.
Fig. 7 shows the synoptic diagram of the coating route of liquid crystal panel frame adhesive coating process the 4th embodiment of the present invention.Default liquid crystal overlay area is rectangle, and the diagonal line of default liquid crystal overlay area be arranged in parallel, but is with top three embodiment differences: default liquid crystal overlay area is not to be arranged in rows, and arranges but be diagonal line.Only through once, the coating route of frame adhesive is A-B-C-D-E-F-G-H-I-J-K-L-M to the injecting glue device on each limit of default liquid crystal overlay area, and only through once, wherein A is starting point on each limit of default liquid crystal overlay area, and M is terminal point.Preferably, starting point A and terminal point M are outside the frame adhesive pattern of closure.Certainly, starting point A and terminal point M also can select one outside the frame adhesive pattern of closure.The same with the 3rd embodiment, the coating route on the both sides of coating once turns to mostly occurring continuously arbitrarily, the steering angle that turns to is 90 °, and arbitrarily continuously the both sides of coating comprise both sides that same default liquid crystal overlay area is continuous and adjacent adjacent both sides, two default liquid crystal overlay areas.
Be appreciated that, the path of frame adhesive coating route when turning to of above-mentioned each embodiment can be the combination of arc or straight line or arc and straight line, though and the frame adhesive of above-mentioned each embodiment coating route all be the frame adhesive that once is coated with three liquid crystal panels be example, but this just describes frame adhesive coating route as demonstration, the quantity of the frame adhesive of a coating of liquid crystalline panel of the present invention is not made restriction, its quantity can be more than three.In addition, the coating route of liquid crystal panel frame adhesive of the present invention can have other variations, is not limited by above-described embodiment, does not break away from the situation of technical solution of the present invention essence, all belongs to the scope of protection of the invention.
