LED display, also called electronic display, is composed of LED dot matrix and LEDpc panel. It displays the display screen of text, picture, animation, video and content through the 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, less failure, large viewing angle and long visible distance. It can display changing texts, graphic images, numbers, and videos. It can be used not only in indoor environments but also in outdoor environments. It has the advantages that LCD screens, projectors, and TV walls cannot match. It is also widely used in stations and 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 rapid development of LED display screens has been widely recognized, and it is inseparable from its own advantages. It has: high brightness, miniaturization, long life, low operating voltage, low power consumption, stable performance and impact resistance. LED display screen display is bright, three-dimensional, strong as oil painting, moving like a movie, LED development prospects are extremely broad, currently moving towards higher brightness, higher weather resistance, higher luminous density, higher Uniform illumination, reliability, and full colorization.
The LCD splicing screen is a splicing screen body that uses a splicing method of the LCD display unit to realize a large screen display effect through a splicing control software system. At present, the common splicing methods are 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.
LCD splicing screens have higher brightness than TV and PC LCD screens. The brightness of a TV or PC LCD screen is generally only 250~300cd/m2, while the brightness of a DID LCD screen can reach 700cd/m2 or more. Since each point of the LCD maintains that color and brightness after receiving the signal, unlike the CRT, it is necessary to constantly refresh the pixel points. Therefore, the LCD has uniform brightness, high image quality and absolutely no flicker, and the picture is more delicate when viewed at close range.
Then, compared with the LCD splicing screen, who is the real king of the screen display, we will know at a glance from the following aspects.
Lifetime LEDs have a longer life than LCDs.
The refresh rate of the refresh rate LED is higher than that of the LCD, and the response speed is faster.
In terms of energy consumption, LEDs are much lower in energy consumption than LCDs, so LEDs are more environmentally friendly.
In terms of brightness, the LED is relatively purer than the LCD, has a wider color gamut, and has a higher brightness, which can increase the viewing angle of the display.
Viewing distance: LCD is suitable for close-up viewing, but currently the dot spacing of LEDs has been 2mm, and close-up viewing is not a problem.
The backlight LED screen uses LED lights, LEDs, LCD splicing screens are cold cathode ray tubes, and the LCD is cheaper in terms of price.
So to choose between the two, depends on the scope and requirements of the specific use. LCD is the LCD screen with low brightness. It is suitable for indoor use within 10 meters. It is used for monitoring center or video conference. LED is composed of countless LEDs. It has large dot distance and is suitable for outdoor or remote distance viewing. Indoor screen brightness can reach 1000. -2000 models have different brightness, the best viewing distance can reach 6-80 meters for larger venues. However, since the dot pitch of the LED display has been 2mm, the LED electronic display has entered the field of monitoring, and the application field of the display will continue to expand in the future.
