how to choose LCD lcd screen and led lcd screen?

 do you know how to choose LCD lcd screen and led lcd screen? Today for the specific analysis of everyone, I hope to help you.
 The service life LED is longer than that of LCD.
 Refresh rate LED the refresh rate is higher than LCD and the response speed is faster.
 energy consumption LED is much lower in energy consumption than in LCD, so the use LED environmental protection is better.
 The brightness aspect LED compared to the LCD color intelligent display module is more pure, has the wider color domain, the brightness is also relatively high, may increase the display screen angle of view.
 Viewing distance: LCD suitable for close viewing, but the current LED point spacing has achieved 2 mm, close viewing is not a problem.
 LED backlight screen is used for LED lights, luminous diodes, LCD splicing screen is used for cold cathode ray tubes, the price is LCD cheaper.
With the expansion and penetration of the application range of LED display screen, the application competition of LED electronic display screen and LCD splicing screen is becoming more and more fierce. Today both can be applied on some occasions, so how to choose? What are the differences and advantages between them? The following information will be answered in detail for you.
LED display screen, also called electronic display screen, is composed of LED lattice and LED pc panel, which displays the display screen of text, picture, animation, video and content through the bright and out of red, blue, white and green LED lights. It is driven by low voltage scanning and has the characteristics of low power consumption, long service life, low cost, high brightness, less fault, large angle of view and long visual distance. It can display changing text, graphic image, digital, video; not only can be used in the indoor environment but also in the outdoor environment, with LCD screen, projector, TV wall incomparable advantages, but 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 mining enterprises, transportation, education systems, auction houses, industrial enterprise management and other public places.
 LED the rapid development of the display screen due to its wide attention is inseparable from its own advantages. It has: high brightness, miniaturization, long life, low working voltage, low power consumption, stable performance and shock resistance. LED display screen display screen bright color, strong sense of three-dimensional, static as oil painting, moving as film, LED development prospects are extremely broad, at present is moving towards higher brightness, higher climate resistance, higher luminous density, higher luminous uniformity, reliability, full coloration direction.
The LCD splicing screen is a kind of splicing screen body which uses the splicing mode of the LCD display unit to realize the large screen display effect through the splicing control software system. The current common splicing methods are 5.3 MM of 55 inch ultra narrow edge LCD splicing ,6.7 MM of 46 inch ultra narrow edge LCD splicing screen ,47 inch LCD splicing ,60 inch LCD splicing wall and 40 inch narrow edge LCD splicing system.
LCD splicing screen has higher brightness compared to TV and PC LCD screen. The brightness of TV or PC LCD screens is generally only 250~300 cd/m2, and the brightness of DID LCD screens can reach more than 700. Since each point of the LCD maintains that color and brightness after receiving the signal, it does not require constant refresh of the pixel as CRT does. As a result, LCD brightness uniform, high quality and absolutely no flicker, close view, the picture is more delicate.
