What is the purpose of various information of LCD? What are the characteristics? What are the advantages?

The characteristics of LCD screen: no radiation, good for health: LCD screen is completely radiation-free, light and save space: compared with relatively bulky LED screen, LCD screen only needs one-third of the space; Power saving, no high temperature: it is a low-power product, which can not generate heat at all (the main power consumption and heating part exist in backlight tubes or LEDs), while CRT monitors will inevitably generate high temperature due to imaging technology; Soft screen does not hurt the eyes: LCD screen will not flicker, which can reduce the damage of the monitor to the eyes, and the eyes are not easy to get tired. Selection of LCD: The design adopts 1602 LCD, and the 1602 LCD module has the characteristics of small size, low power consumption and rich display contents. The Chinese name of LCD monitor is LCD monitor, which is widely used in all fields of the world. There are many kinds of liquid crystals, which are usually classified according to the characteristics of the central bridge bond and ring of liquid crystals.

At present, more than 10000 kinds of liquid crystal materials have been synthesized, among which there are thousands of commonly used liquid crystal display materials, mainly biphenyl liquid crystal, phenylcyclohexane liquid crystal and ester liquid crystal. Liquid crystal display materials have obvious advantages: low driving voltage, low power consumption, high reliability, large display information, color display, no flicker, harmless to human body, automatic production process, low cost, and can be made into liquid crystal displays of various specifications and models, which is convenient to carry. Due to these advantages, the sizes of computer terminals and televisions made of liquid crystal materials can be greatly reduced. Liquid crystal display technology has a far-reaching impact on the structure of display imaging products, and promoted the development of microelectronics and photoelectric information technology. According to the color change of liquid crystal, people use it to indicate temperature, alarm poison gas and so on. For example, liquid crystal can change from red to green and blue with the change of temperature.
