Many people in our lives cannot really distinguish between LCD screens and LCD screens. Let me introduce the difference between the two in detail today!
The brightness is good, which makes the backlight more uniform. Such a display can be made thinner and more power-saving, the life of the LED is also longer than that of the CCFL, and the color is stable and not easy to yellow.
LED displays use LED light sources, which are light-emitting diodes (like the red and blue indicator lights on household appliances). Such light-emitting diodes are very power-saving, and because they are not light tubes, they can be formed into an array and evenly distributed behind the LCD screen.
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 has a certain life span and will turn yellow over time.
Ordinary LCD screens use CCFL light sources, which are cold cathode fluorescent tubes. There are one on each side of the screen. There is a backlight board on the back of the display. It is composed of fluorescent materials. Make the entire screen light up evenly.
The LED display is the same as the liquid crystal display, the main difference is that the backlight of the screen produces bright light.
