With the expansion and penetration of the application scope of LED display, the application competition of LED electronic display and LCD liquid crystal screen is becoming more and more fierce. Today both can be applied in some occasions, so how to choose? What are the differences and advantages of the two? The following information will give you a detailed answer. LED display, also known as electronic display, is composed of LED dot matrix and LED pc panel. It displays text, pictures, animation, video, and content by turning on and off red, blue, white, and green LED lights. It adopts low-voltage scanning drive, which has the characteristics of low power consumption, long service life, low cost, high brightness, few failures, large viewing angle, and long visual distance. It can display changed text, graphic images, numbers, and videos; it can be used not only in indoor environments but also in outdoor environments, with incomparable advantages in LCD screens, projectors, and video walls, and is also widely used in stations, docks, Airports, hotels, banks, securities markets, construction markets, taxation, shopping malls, hospitals, finance, industry and commerce, post and telecommunications, sports, advertising, factories and mines, transportation, education systems, auction houses, industrial enterprise management and other public places.
The reason why the LED display has been widely valued and developed rapidly is inseparable from its own advantages. It has: high brightness, miniaturization, long life, low operating voltage, low power consumption, stable performance and impact resistance. The LED display screen has bright colors and strong three-dimensional sense. It is as quiet as an oil painting and moving as a movie. The development prospect of LED is extremely broad. Currently, it is moving towards higher brightness, higher weather resistance, higher luminous density, higher Lighting uniformity, reliability, and full color development.
The LCD liquid crystal screen is a splicing screen body that uses the splicing method of LCD display units to realize the large-screen display effect through the splicing control software system. At present, the common splicing methods include 5.3MM 55-inch ultra-narrow LCD splicing, 6.7MM 46-inch ultra-narrow LCD splicing screen, 47-inch LCD splicing, 60-inch LCD splicing wall and 40-inch narrow-edge LCD splicing system. Compared with TV and PC LCD screen, LCD LCD screen has higher brightness. The brightness of TV or PC LCD screen is generally only 250~300cd/m2, while the brightness of DID LCD screen can reach more than 700cd/m2. Because each point of LCD maintains the color and brightness after receiving the signal, unlike CRT, it needs to constantly refresh the pixel points. Therefore, the LCD brightness is uniform, the picture quality is high, and there is absolutely no flicker, and the picture is more delicate when viewed at close range. Then compared with the LED display screen and the LCD liquid crystal screen, who is the real king of the screen display, we will understand at a glance from the following aspects. The service life of LEDs is longer than that of LCD screens. The refresh rate of the LED is higher than that of the LCD screen, and the response speed is faster. In terms of energy consumption, the energy consumption of LEDs is much lower than that of LCD screens, so the use of LEDs is more environmentally friendly. In terms of brightness, LEDs have relatively pure colors compared to LCDs, have a wider color gamut, and have higher brightness, which can increase the viewing angle of the display. Viewing distance: The LCD screen is suitable for close-up viewing, but the current LED dot pitch has been 2mm, so close-up viewing is not a problem. The LED backlight screen uses LED lights, light-emitting diodes, and the LCD liquid crystal screen uses a cold cathode ray tube, which is cheaper in terms of price. So to choose between the two, it depends on the scope and requirements of the specific use. LCD is a low-brightness liquid crystal screen, which is suitable for viewing within ten meters indoors, mostly for monitoring centers or video conferences. LED is composed of numerous light-emitting diodes, with large dot pitch, suitable for viewing outdoors or far away. The indoor screen brightness can reach 1000 -2000 models have different brightness, and the best viewing distance can reach 6-80 meters, which is suitable for use in larger venues. However, since the dot pitch of the LED display has reached 2mm, the current LED electronic display has entered the monitoring field, and the application field of the display will continue to expand in the future.
