Cutting technique

Abstract

The invention provides a cutting technique suitable for cutting a workpiece. The cutting technique comprises the following steps: at first, an optics membrane is stuck on the surface of the workpiece; then, the surface of the workpiece is cut by a machining tool, so as to form an initial crack on the edge of the workpiece; finally, a cutting beam is supplied by which the workpiece and the optics membrane are cut simultaneously starting from the initial crack. Employing the cutting technique of the invention can not only save the technique time, and reduce the technique cost, but also have a better rate of finished products.

Description

technical field [0001] The present invention relates to a cutting process, and in particular to a cutting process using a cutting beam. Background technique [0002] A liquid crystal display panel is mainly composed of two substrates sandwiching a liquid crystal layer, such as an active element array substrate and a color filter substrate, and the substrates of these substrates are usually made of glass. Therefore, how to improve the yield of these substrates during cutting and molding is very important. [0003] Figure 1A to Figure 1C It is a schematic flow chart of a cutting process for a known liquid crystal display panel, and Figure 1D It is a schematic cross-sectional view of cutting a liquid crystal display panel with a knife wheel. Firstly, a finished product 100 after assembly of an active element array substrate (not shown) and a color filter substrate (not shown) is provided, as shown in Figure 1A shown. Among them, the finished product 100 has multiple stri...

Problems solved by technology

Additionally, due to the use of Figure 1D The illustrated cutter wheel 130 mechanically cuts the finished product 100, so the edge of the obtained liquid crystal display panel 110 is likely to have an uneven section (burr), which in turn affects the processing accuracy and the yield of the subsequent process.
