Compared with the traditional CRT, the LCD liquid crystal display is not only small in size, thin in thickness, light in weight, low in energy consumption, low in working voltage (1.5 to 6V), no radiation, no flicker, and can be directly matched with CMOS integrated circuits.



(1) Power saving, no high temperature

It is a low power consumption product, which can achieve no heat at all (the main power consumption and heating part are in the backlight tube or LED), and the CRT display screen inevitably generates high temperature due to the imaging technology.



(2) Thin body, saving space

Compared with the more bulky CRT display, the LCD display only needs one-third of the space of the former.



(3) Low radiation, good health

The radiation of liquid crystal display is much lower than that of CRT display (it is only low, not completely without radiation, electronic products have more or less radiation), which is a boon for people who work in front of computers all day.



(4) The picture is soft and does not hurt the eyes

Unlike CRT technology, the LCD screen does not flicker, which can reduce the damage of the screen to the eyes, and the eyes are not easy to fatigue. The LCD display is a display that uses liquid crystal as its material. Liquid crystals are organic compounds between solid and liquid. It will become a transparent liquid when heated, and a crystalline turbid solid after cooling. Under the action of an electric field, the arrangement of the liquid crystal molecules will change, which will affect the change of light passing through it. This change of light can be expressed as a change of light and dark through the action of the polarizer. In this way, people finally control the light and dark changes through the control of the electric field, so as to achieve the purpose of displaying images.
