The advantages and working principle of LCD.

- Nov 07, 2019-

Liquid crystal display, or lcd (liquid crystal display), is a flat ultra-thin display device, which consists of a certain number of color or black and white pixels, placed in front of the light source or reflection surface. Liquid crystal refers to a substance with both liquid and crystal characteristics in a certain temperature range. Liquid crystals are not liquid, solid and gaseous, but the fourth state of matter. Because liquid crystals are very sensitive to electricity, magnetic field, light and temperature, using this characteristic to convert them into visual signals is liquid crystal display.

LCD (liquid crystal display), may not be a new term for many users, but the history of this technology may far exceed our imagination. Lcd display is liquid crystal display, the advantage is that the fuselage is thin, the area is small, the radiation is small, and gives people the image of a healthy product. But liquid crystal displays do not necessarily protect the eyes, which depends on everyone's habit of using computers.

The working principle of lcd liquid crystal display is that there are many liquid crystal particles in the display. They are arranged regularly in a certain shape, and the colors on each side of them are different: red, green, blue. These three primary colors can be restored to any other color, and when the display receives the display data from the computer, it will control each liquid crystal particle to rotate to a different color surface to combine into a different color and image!

Also because of the shortcomings of liquid crystal display screen is that the color is not bright enough, but the visual angle is not high and so on. Maybe you see a good display in the store where you buy the LCD, but when you move the product home, you find that the effect is very different and disappointing. This is because the main light source of the LCD screen is to reflect the external light source, and there is enough light where you buy the product, so there will be a different display effect.
