In fact, the LED display and the LCD display are the same, they are all liquid crystal, and there is no difference. The main difference is that the backlights that make the screen shine are different.
In fact, the LED display and the LCD display are the same, they are all liquid crystal, and there is no difference. The main difference is that the backlights that make the screen shine are different.Ordinary LCD uses CCFL light source, that is, cold cathode fluorescent lamp (similar to the scanning lamp in the copy). There is one on each side of the screen, and there is a backlight on the back of the display, which is composed of fluorescent materials. The light sources on both sides can be evenly distributed on the back of the whole screen, so that the whole screen can be evenly lit. However, due to technical limitations, the brightness of such a display is not completely uniform, but it is difficult to find it. At the same time, the lamp also has a certain life, and it will turn yellow after a long time.Led liquid crystal display uses LED light source, which is light-emitting diodes (like the red and blue indicator lights on household appliances). This led is very energy-saving, and because it is not a lamp, it can form an array one by one and distribute evenly behind the LCD screen. Good brightness, more uniform backlight. This kind of display can be thinner and more power-saving, the life of LED is longer than that of CCFL, the color is stable, not easy to yellow.Remember that both monitors use the same screen, no difference. It's just that the backlight is different...
