With the expansion and penetration of LED display, the competition of LED electronic display and LCD LCD is becoming more and more intense. Today, the two can be applied on 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 screen, also called electronic display, is made up of LED dot matrix and LED PC panel. The display screen of text, picture, animation, video and content is displayed by the light of red, blue, white and green LED lights. It uses low voltage scanning drive, and has the characteristics of less power consumption, long service life, low cost, high brightness, few failures, large viewing angle, and long viewing distance. It can display the changing characters, graphics, figures, and video. It can be used not only in the indoor environment but also in the outdoor environment. It has the advantages of the LCD screen, the projector and the TV wall. It is also widely used in the station, the dock, the airport, the hotel, the bank, the securities market, the construction market, the tax, and the business. Field, hospital, finance, industry and commerce, post and telecommunications, sports, advertisement, factory and mining enterprise, transportation, education system, auction house, industrial enterprise management and other public places.
The reason why LED display has been widely regarded and developed rapidly is that it is inseparable from its advantages. It has: high brightness, miniaturization, long life, low working voltage, low power consumption, stable performance and impact resistance. LED display display screen color bright, three-dimensional sense, static such as oil painting, such as film, LED development prospects are extremely broad, is currently facing higher brightness, higher climate resistance, higher luminous density, higher luminescence uniformity, reliability, color direction development.
The LCD LCD is a splicing screen that uses LCD display unit to splice and control the software system to achieve the effect of large screen display. The common splicing methods are 5.3MM 55 inch ultra narrow edge liquid crystal splicing, 6.7MM 46 inch ultra narrow edge LCD splicing, 47 inch LCD splicing, 60 Inch LCD splice wall and 40 inch narrow edge liquid crystal splicing system.
LCD LCD screen
Compared with TV and PC LCD, LCD LCD has higher brightness. The brightness of TV or PC LCD is only 250~300cd/m2, while the brightness of DID LCD can reach more than 700cd/m2. Because each point of LCD keeps the color and brightness after receiving the signal, unlike CRT, it needs to constantly refresh pixel points. Therefore, LCD has uniform brightness, high quality and absolutely no flicker.
Then LED display and LCD LCD screen, who is the real screen king, specifically from the following several aspects of analysis we will be clear at a glance.
The service life of LED is longer than that of LCD LCD screen.
The refresh rate of LED is higher than that of LCD LCD, and the response speed is faster.
In terms of energy consumption, LED is much lower in energy consumption than LCD LCD screen. Therefore, the use of LED is better in environmental protection.
In terms of brightness, LED is more pure than LCD, and has wider gamut and higher brightness. It can increase the viewing angle of the display.
Viewing distance: LCD LCD screen is suitable for close viewing, but at present LED's point spacing has been 2mm, and close viewing is not a problem.
The LED backlight source uses LED lights, light emitting diodes, LCD LCD screens with cold cathode ray tubes, and LCD is cheaper in terms of price.
Therefore, the choice of the two party depends on the scope and requirements of the specific use. LCD is a liquid crystal screen with low brightness for less than ten meters to watch for monitoring center use or video conference, LED is composed of numerous light-emitting diodes, big spot, suitable outdoor or far distance to watch, indoor screen brightness can reach 1000-2000 models different brightness is not the same, the best viewing distance can reach 6-80 Rice is suitable for large site environment. However, as the point spacing of LED displays has been 2mm, the current LED electronic display screen has entered the monitoring field, and the future application field will continue to expand.
