The applications of liquid crystal displays include small-sized portable information products, such as personal digital assistants (PDAs), or ordinary-sized notebook computers or desktop-type LCD screens, and even large-sized LCD TVs.

And a fixed interlocking body is formed after punching each time, only a fixed number of cold cathode lamp tubes can be installed, and the number of lamp tubes cannot be expanded or reduced, and the expansibility in use is limited.
