An in-line operation for manufacturing liquid crystal displays. First, a liquid crystal cell is pulled out from a first stocking region and placed inside a processing station by a loader. The liquid crystal cell is shunt, beveled and corner-cut by a shunt and bevel unit inside the processing station. The liquid crystal cell is next transferred directly to a brush-washing unit for cleaning. After cleaning, the semi-finished product is directly transferred from a linked stocking region to an affixing unit for attaching a polarizer onto the liquid crystal cell. The semi-finished product is transferred to a second stocking region by an unloader. Sample inspection can be carried out when the semi-finished product is still within the linked stocking region.

1. Field of Invention
The present invention relates to a method of manufacturing liquid crystal display (LCD). More particularly, the present invention relates to an in-line operation system and flow plan for manufacturing liquid crystal display.
2. Description of Related Art
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention. In the drawings,
FIG. 1 is a flow chart showing the steps in a conventional off-line operation for fabricating liquid crystal display from the assembly of liquid crystal cell to the assembly of liquid crystal module;
FIG. 2 is a flow chart showing the steps in an on-line operation for fabricating liquid crystal display by integrating the assembly of liquid crystal cell and liquid crystal module according to a first preferred embodiment of this invention;
Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
FIG. 2 is a flow chart showing the steps in an on-line operation for fabricating liquid crystal display by integrating the assembly of liquid crystal cell and liquid crystal module according to a first preferred embodiment of this invention. FIG. 3 is a schematic diagram showing an on-line operation system for fabricating liquid crystal display by integrating the assembly of liquid crystal cell and liquid crystal module according to the first preferred embodiment of this invention.
In this invention, some of the steps for assembling a liquid crystal cell are similar to the conventional technique. When the liquid crystal is sealed inside liquid crystal display panels, fabrication of the liquid crystal cell is considered complete. As shown in FIGS. 2 and 3, a liquid crystal cell 300 is placed into a first stocking region 302 in step 200. To carry out subsequent processing, the liquid crystal cell 300 is pulled out from the first stocking region 302. The first stocking region 302, for example, can be the interior of an automatic stocking machine.
