then compared with LCD splicing screen, who is the real king of screen display, we will be clear at a glance from the following aspects.
service life the service life of LED is longer than that of LCD.
refresh rate the refresh rate of LED is higher than that of LCD, and the response speed is faster.
in terms of energy consumption, LED is much lower than LCD in terms of energy consumption, so it is better to use LED for environmental protection.
in terms of brightness, compared with LCD, the color of LED is relatively pure, with wider color gamut and higher brightness, which can increase the viewing angle of the display screen.
Viewing Distance: LCD is suitable for close viewing, but at present the dot spacing of LED has been 2mm, and close viewing is not a problem.
LED backlight screen uses LED lights, light emitting diodes, LCD splicing screen uses cold cathode ray tube, LCD is cheaper in price.
with the expansion and infiltration of the application scope of LED display screen, the application competition between LED electronic display screen and LCD splicing screen is becoming more and more fierce. Today, both can be applied in some occasions, so how should we choose? What are the differences and advantages between the two? The following information will give you a detailed answer.
LED display screen, also called electronic display screen, is composed of LED dot matrix and LED pc panel, through red, blue, white, the green LED light is on and off to display text, pictures, animations, videos, and content display screens. It adopts low voltage scanning drive and has the characteristics of low power consumption, long service life, low cost, high brightness, few faults, large viewing angle, long visual distance, etc. It can display changing text, graphic images, numbers and videos; It can be used not only in indoor environment but also in outdoor environment, and has incomparable advantages over liquid crystal display screen, projector and TV wall, it 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 system, auction house, industrial enterprise management and other public places.
The reason why LED display screen has received extensive attention and developed rapidly is inseparable from its own advantages. It has: high brightness, miniaturization, long service life, low working voltage, low power consumption, stable performance and impact resistance. The LED display screen shows bright colors, strong stereoscopic impression, as quiet as oil painting and as moving as a movie. The development prospect of LED is extremely broad, at present, it is developing towards higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability and panchromatic direction.
The LCD splicing screen is a kind of splicing screen body that adopts the splicing mode of LCD display units and realizes the large screen display effect through the splicing control software system. At present, there are 5 common splicing methods. 3MM 55-inch ultra-narrow LCD splicing, 6. 7 MM-inch 46-inch ultra-narrow LCD splicing screen, 47-inch LCD splicing, 60-inch LCD splicing Wall and 40-inch narrow-sided LCD splicing system.
LCD splicing screens have higher brightness than TV and pc LCD screens. The brightness of TV or pc LCD screen is generally only 250 ~ 300cd/m2, While did LCD brightness can reach more than 700cd/m2. Because every point of LCD keeps that kind of color and brightness after receiving the signal, it doesn't need to refresh the pixel point like CRT. Therefore, the LCD has uniform brightness, high image quality and absolutely no flicker, and the picture is more exquisite when viewed closely.
