LCD display and LED display are the two most widely used display technologies, and there are some obvious differences between them. In this article, we will give you a detailed introduction to the differences between LCD display and LED display.


First, let's look at the LCD display. LCD, the full name of liquid crystal display, is a display screen that uses the optical properties of liquid crystal molecules under the action of electric fields. The screens are illuminated by an external light source, usually a cold cathode fluorescent lamp (CCFL). The advantage of CCFL is that the brightness is high and uniform, but it requires a complex optical path design, so the thickness of the LCD is relatively large. At the same time, due to the low energy efficiency of CCFL, the LCD screen consumes more power. In addition, because the life of CCFL is relatively short, the service life of the LCD screen is also short, generally about 40,000 hours.


Compared with LCD display, LED display uses light-emitting diodes as backlight, which makes LED display have many advantages. First, the brightness of leds is higher and more uniform, so the display quality of LED displays is higher. Second, the volume of leds is smaller, so LED displays can be made thinner and lighter. In addition, leds are more energy efficient, so LED displays consume less power and have a longer service life. Data shows that LED screens consume 48% less power than LCD screens. At the same time, the service life of the LED screen is more than 50,000 hours.


In addition, LED display and LCD display also have differences in color gamut. Color gamut refers to the range of colors that a display device can display. NTSC is the standard for determining the gamut of colors that a color display can display. Ordinary flat display CRT can reach the NTSC100% level, while ordinary LCD can only reach about 78%. However, LED backlights can easily get more than 100% of the NTSC color area. This means that the LED display can display a wider range of colors, more colorful.

Besides, the refresh rate of LED displays is much higher than that of LCD displays. Refresh rate refers to the number of times the display device refreshes per second, which affects the degree of flicker of the picture. LED display refresh rate of more than 125HZ, the picture is stable and smooth, there will be no common flicker and jitter LCD phenomenon.


Finally, the LED display also has a wider viewing Angle. The LED provides a viewing Angle of more than 160°, which means that you can get a clear image no matter which Angle you view the screen from. In contrast, the viewing Angle of LCD is about 100° to 120°, and the viewing Angle is small.


In general, LED display and LCD display have their own advantages and disadvantages. However, with the continuous progress and development of technology, LED display has become the current mainstream display technology. It is widely used in various display devices for its advantages of high brightness, high refresh rate, high life and low energy consumption. At the same time, with the reduction of costs and the popularization of technology, the application field of LED display will continue to expand.
