An LCD TV is essentially a display device that requires a signal source to provide image signals to display a variety of images. LCD TVs and signal sources must be connected and transmitted through interfaces. Different signal sources have different interface types. Therefore, LCD TVs are usually equipped with multiple sets of different interfaces for users to choose from.
Common interfaces of LCD TVs include AV compound video interfaces, S-terminal interfaces, chromatic aberration interfaces, V
