The basic types and application industries of LCD display screens

LCD display screens are classified according to display technology, generally including dot matrix screens, character screens, code break screens, and TFT color screens. They are classified according to display type: positive display, negative display, full transparency, semi transparency, and radiation. According to the material structure used in LCD display screens, liquid crystals can be divided into three categories: TN, STN, TFT, etc. According to current technical principles, they can be further divided into many categories such as TN, STN, FSTN, DSTN, TFT, etc.

The characteristics of LCD liquid crystal display screens are small size, thin shape, light weight, low energy consumption (1-10 micro watts/square centimeter), low heat generation, low working voltage (1.5-6 volts), pollution-free, radiation-free, and static induction free. Especially, they have a wide field of view, large display information, no flicker, and can be directly matched with CMOS integrated circuits. At the same time, they are also true "flat panel" display devices.

LCD displays are often seen in various industry applications, including control equipment in the industrial control industry, POS machines in financial terminals, telephones in the communication industry, charging stations for new energy equipment, fire alarms, 3D printers, and other instruments and equipment.
