Four Characteristics of LCD display

Compared with traditional CRT, LCD display is not only small in size, thin in thickness, light in weight, low in energy consumption, low in operating voltage (1.5 to 6V), but also radiation-free, non-flickering and can directly match CMOS integrated circuits.

(1) Save electricity and do not produce high temperature.

It is a low-power product, and can completely avoid heating (mainly in the backlight lamp or LED), while CRT display, due to the problems of imaging technology, will inevitably produce high temperature.

(2) Thin fuselage, saving space

Compared with bulky CRT displays, LCD display requires only one third of the space of the former.

(3) Low radiation for health

LCD radiation is much lower than CRT display (just low, not completely without radiation, electronic products more or less have radiation), which is a piece of good news for people who work in front of computers all day.

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

Unlike CRT technology, LCD screen will not flicker, which can reduce the damage to the eyes of the display, and the eyes are not easy to fatigue. LCD display is a kind of display using liquid crystal as material. Liquid crystals are organic compounds between solid and liquid phases. When heated, it becomes a transparent liquid, and when cooled, it becomes a crystalline turbid solid. Under the action of electric field, the arrangement of liquid crystal molecules will change, thus affecting the change of light through the polarizer, which can show the change of light and shade. In this way, through the control of electric field, people ultimately control the light and shade changes, so as to achieve the purpose of displaying images.
