Problems solved by technology
[0004] In the existing glass substrate cutting method, the cutter wheel of the cutting machine usually directly contacts the surface of the glass substrate, and glass shavings are easily generated during cutting, and the generated glass shavings are easy to splash everywhere, and some of them adhere to the surface of the glass substrate, which affects the glass substrate on the one hand. The cleanliness of the substrate surface requires an additional cleaning process to remove the glass shavings; on the other hand, the glass shavings will scratch the touch film layer formed on the surface of the glass substrate, causing an open circuit in the capacitive touch screen obtained after cutting, affecting the product. Yield rate
In addition, during the cutting process using the cutter wheel, defects such as edge chipping or bright edges are prone to occur on the edge of the glass substrate, which affects the edge strength of the multiple capacitive touch screens obtained after cutting.

The invention relates to the technical field of flat plate display, and particularly relates to a substrate cutting method. The cutting method at least comprises the following steps: providing a substrate which is at least provided with a first surface, wherein the first surface at least comprises a plurality of first areas; forming a plurality of film layers and a plurality of first cutting lines on the first surface, wherein the first film layer at least covers the first areas, the first film layers define a plurality of interval areas for the first surface, and the first cutting lines are positioned in the interval areas; and cutting the substrate along the first cutting lines.
Description
Technical field [0001] The present invention relates to the technical field of flat panel displays, and in particular to a substrate cutting method. Background technique [0002] The current display panel is generally a liquid crystal display panel, or a panel including a touch screen and a display screen. The display screen (or liquid crystal display panel) is used to display images or numbers, and the touch screen, as an input device, is equivalent to an external keyboard. Among them, capacitive touch panels are increasingly replacing traditional resistive touch panels due to their advantages of multi-touch, high transmittance, and long service life. They are used in mobile phones, players, e-books, netbooks, personal digital assistants, and tablet computers. use. [0003] The capacitive touch screen is usually composed of a glass substrate and a touch film layer formed on the surface of the glass substrate. The manufacturing process of the existing capacitive touch screen is ...
