Description

Liquid crystal module manufacturing method

The invention relates to a manufacturing method, in particular to a method for manufacturing a liquid crystal module of a specific size by cutting.

Generally, liquid crystal panels have specific mainstream dimensions when they are manufactured. The mainstream size of each generation will be different. For example, the size of the motherboard of the seventh generation panel is 1870×2200 mm. If it is cut into 32 inches, it can be used without waste. 12 pieces of liquid crystal panels with mainstream dimensions have been produced, so it is most economical in terms of cost. However, since most of the early LCD panels were used in computer imaging, there were not many requirements for size. With the advancement of technology, LCD panels are gradually moving toward larger sizes, but in terms of economic benefits, Small-size LCD screens or large-size LCD TVs are cut to the mainstream size. Although the aforementioned liquid crystal panel having a mainstream size is suitable for use as a television or a computer screen, it is not suitable for use in fields such as advertisements and the like which require special specifications.

1 and 2 are US 7,525,633 B2 invention patents, which provide a method for manufacturing a module unit 1 into a liquid crystal module 11 having a specific size, that is, a cutting line 10 for distinguishing the module The unit 1 can be cut into the liquid crystal module 11 and a remaining module 12. The module unit 1 comprises: two spaced substrates 13 , a peripheral sealing strip 15 connected between the substrates 13 and jointly defining a chamber 14 , a liquid crystal medium 16 filled in the chamber 14 , and Two sheets of polarizing plates 17 respectively adhered to the outer sides of the substrates 13 are provided for the purpose of development. A member such as an alignment film, a color filter or the like is often installed, and since the improvement of the present invention is not related to the aforementioned elements, it will not be described.

The method of the aforementioned US invention patent includes the following steps:

Step 1: Prepare the module unit 1. The module unit 1 is generally a commercially available product having a mainstream size specification.

Step 2: cutting the module unit 1 into the liquid crystal module 11 and the remaining module 12 along the cutting line 10. After cutting, the liquid crystal module 11 is formed adjacent to one side of the cutting line 10. A bare side 111, that is, after cutting, the liquid crystal medium 16 originally enclosed by the peripheral weather strip 15 can flow out from the bare side 111.

Step 3: A portion of the liquid crystal medium 16 is removed along the exposed side 111 of the liquid crystal module 11 to form a filling space 113 between the substrates 13 of the liquid crystal module 11.

Step 4: Applying an adhesive to the filling space 113 of the liquid crystal module 11 to form a side seal 114 for preventing the liquid crystal medium 16 from flowing out.

According to the method disclosed in the foregoing invention patent, the module unit 1 of the mainstream size can be changed into the liquid crystal module 11 having the size specifications, but in the process of manufacturing, the polarizing plates 17 and the substrates must be cut. In addition to the 13th, a portion of the liquid crystal medium 16 is first removed to form the filling space 113, and then the adhesive is filled in the filling space 113 to form the side seal 114. The above processing method is not only complicated in removing the portion of the liquid crystal medium 16 to form the filling space 113, but also filling the inside of the fine filling space 113 is troublesome.

It is an object of the present invention to provide a method of fabricating a liquid crystal module that is easy to process and that simplifies the processing steps.

In the manufacturing method of the present invention, a module unit is cut and fabricated into a liquid crystal module having a specific size, which is distinguished by a cutting line, and the module unit includes the liquid crystal module and a remaining module. The manufacturing method comprises the following steps: Step 1: Preparing the module unit; Step 2: immersing the remaining modules of the module unit and the cutting line together under one liquid surface of a glue solution; and Step 3: along the cutting The tangentially dividing the module unit, when the module unit is cut, and the respective openings are formed on the liquid crystal module and the remaining module, the adhesive solution will close the slit.

The beneficial effect of the invention is that the adhesive solution can be quickly closed by cutting under the liquid surface of the adhesive solution and separating the liquid crystal module from the remaining module below the liquid surface. Incision to achieve the convenience of sizing and simplifying the processing steps.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Referring to FIGS. 3, 4, and 5, a preferred embodiment of the manufacturing method of the present invention is to cut a module unit 2 having a mainstream size into a liquid crystal module 20 of a specific size, that is, The cutting line 21 is distinguished. The module unit 2 includes a residual mode in addition to the liquid crystal module 20. Group 22. The module unit 2 includes two spaced initial substrates 23 ′, two initial polarizing plates 24 ′ respectively attached to the outer sides of the initial substrates 23 ′, and one connected between the initial substrates 23 ′ and An initial seal 26' defining an initial chamber 25' and a liquid crystal medium 27 loaded in the initial chamber 25' are defined.

The liquid crystal module 20 includes two cutting substrates 23 having a smaller area than the initial substrates 23', two cutting polarizing plates 24 having a smaller area than the initial polarizing plates 24', and a surrounding and connecting in the cutting A sealing unit 26 of the substrate 23, and a cutting chamber 25 interposed between the cutting substrates 23 and filled with the liquid crystal medium 27. Each of the cutting substrates 23 has an outer side surface 231, an inner side surface 232, and an end surface 233 adjacent to the cutting line 21.

The seal unit 26 has a U-shape and is connected to the first colloid 261 between the inner sides 232 of the cutting substrate 23, and a first colloid 261 is connected to the first colloid 261 and closes the cutting chamber 25. a second colloid 262, which is a straight strip disposed along the cutting line 21, and has two side rubber portions 263 respectively bonded to the outer side surface 231 of the cutting substrate 23, and a joint The end rubber portion 264 between the side rubber portions 263 and the end surface 233 of the substrate 23 should be cut and so on.

The manufacturing method of this embodiment includes the following steps:

Step 1: First, a module unit 2 having a mainstream size is selected. Preferably, the width of the module unit 2 is equal to the width of the liquid crystal module 20, but the height of the liquid crystal module 20 is smaller than that of the module unit 2. The height is then marked on the module unit 2 to separate the liquid crystal module 20 and the remaining module The cutting line 21 of 22 is cut, and the initial polarizing plates 24' of the module unit 2 are cut in advance.

Step 2: This step is carried out in conjunction with a processing tool 3, which includes a glue tank 32 in which a glue solution 31 is disposed. The glue solution 31 has a liquid surface 311, which is a general liquid crystal display field. Commonly used adhesives are not illustrated. The processing tool 3 further includes two spaced apart cutters 33, two slide rails 34 respectively guiding the cutter blades 33 to reciprocate in a straight line direction, and a clamp 35 for clamping the module unit 2, Each of the cutters 33 has a cutting portion 331 which projects below the liquid level 311 of the adhesive solution 31 and respectively corresponds to the cut substrate 23' of the module unit 2.

In the second step of the embodiment, the module unit 2 is clamped by the clamp 35, and the cutting line 21 of the module unit 2 and the remaining modules 22 below are immersed under the liquid surface 311 of the adhesive solution 31. That is, the liquid surface 311 of the adhesive solution 31 is slightly higher than the cutting line 21, but lower than the cutting polarizing plate 24.

Step 3: The cutters 33 that drive the processing tool 3 are synchronously moved along a straight line to cut the initial substrates 23' of the module unit 2. When the initial substrate 23 ′ of the module unit 2 is broken due to dicing, the liquid crystal module 20 and the remaining module 22 are separated and formed, and a first slit is formed on the liquid crystal module 20 . 200, and forming a second slit 220 on the remaining module 22.

The liquid crystal module 20 is still clamped by the clamp 35, and the first slit 200 is immersed in the adhesive solution 31, because the specific gravity ratio of the adhesive solution 31 used in the general liquid crystal display is loaded in the cutting Liquid in the chamber 25 The crystal medium 27 has a large specific gravity. Therefore, when the liquid crystal module 20 and the remaining module 22 are broken and separated, the liquid crystal medium 27 located in the cutting chamber 25 temporarily remains in the relationship due to the difference in specific gravity. In the cutting chamber 25, the adhesive solution 31 is also quickly wrapped around the first slit 200, and the second colloid 262 of the liquid crystal module 20 is formed.

On the other hand, the remaining module 22 separated from the liquid crystal module 20 will fall into the adhesive groove 32, and the adhesive solution 31 will quickly close the second slit 220 to prevent the remaining module. The internal liquid crystal medium 27 flows out to contaminate the adhesive solution 31. Wait for a period of time and accumulate a larger number of remaining modules 22 and then take them out together.

As can be seen from the above description, the manufacturing method of the present invention is to process a module unit 2 having a mainstream size, and to form a liquid crystal module 20 of a specific size in accordance with cutting and dipping. The above manufacturing method can not only use some low-cost mainstream size module units 2 to manufacture various specific size liquid crystal modules 20, and the manufacturing method is similar to the US7,525,633 B2 invention patent, and also has no need to take out after cutting. The liquid crystal medium 27, as well as the quick and convenient effect of sizing, has the advantages of convenient processing and simplified processing steps compared to the U.S. patent.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
