1. Area scalability. It is difficult to achieve seamless splicing when the LCD area is large, and the LED display can be extended arbitrarily and achieve seamless splicing.

　　2. The luminous flux of the LCD plasma screen decays very quickly. Generally, it needs to be replaced after a year and a half of operation. However, the LED display of Chenzhi Technology will be no problem for at least five years under the same operating conditions.

　　 3. The LED screen swipe machine can use interactive technology to enhance the interaction between the screen swipe machine as an advertising medium and the advertising audience, such as customizing the touch screen and implementing cloud technology broadcast control management.

　　4. In terms of display effects, the high brightness, wide viewing angle and good color reproduction capability of LED displays are also superior to LCD screens. LED swipe screens are generally used in airports, shopping malls, hotels, high-speed railways, subways, cinemas, exhibitions, office buildings, etc. The target customers have strong consumption power and have huge advertising value.

　　 LED screen classification

　　(1) According to the use environment, it is divided into indoor, outdoor and semi-outdoor

The indoor screen area generally ranges from less than 1 square meter to more than ten square meters. Indoor LED displays are used in indoor environments. Such displays have moderate brightness, large viewing angles, close color mixing distance, light weight, and high density, which are suitable for closer viewing .

The outdoor screen area generally ranges from a few square meters to tens or even hundreds of square meters, with a relatively sparse dot density (mostly 2500-10000 dots per square meter), and the luminous brightness is 5500-8500cd/square meter (different orientations and different brightness requirements), which can be used in sunlight When used under direct sunlight, the viewing distance is tens of meters away, and the screen has good wind and rain resistance and lightning protection capabilities.

　　 Semi-outdoor screen is between outdoor and indoor. It has high luminous brightness and can be used outdoors in non-direct sunlight. The screen body is sealed to a certain extent, usually under the eaves or in the shop window.

　　(2) According to the color, it is divided into single color, double primary color, three primary color (full color)

　　Monochrome refers to the luminescent material with only one color of the display screen, mostly single red, and yellow-green can also be used in some special occasions (such as funeral homes).

　　The dual-color LED display consists of red and green LED lights. The dual-color display with 256-level grayscale can display 65,536 colors (the dual-color screen can display 3 colors of red, green and yellow).

　　The full-color LED display consists of red, green and blue LED lights, which can display white balance and 16,777,216 colors.
