Comparison of LCD splicing screen and LED screen(2)
Continued to the last topic of "Comparison of LCD splicing screen and LED screen", we analyzed the advantages and disadvantages of LCD splicing screens. Now, let`s have the analysis of LED displays.
2. LED display
LED display is a common splicing large-screen display, which is mostly used for outdoor advertising, exhibitions, etc. In recent years, as its dot pitch has become smaller and smaller, it has also been gradually used in indoor occasions. For example, press conferences, lecture halls, exhibition halls, etc., are also used in the halls of some enterprises, but they are basically used as display text or video, and the functions are relatively simple.
Advantage: no seams. We all know that no matter how LED is spliced, one unit board is connected to another unit board. There is no seam in the middle of the screen. The integrity of the entire spliced large-screen display is stronger. This is its biggest advantage over LCD splicing. .
Disadvantages: Although the dot pitch of LEDs has been reduced a lot, the resolution still does not meet the requirements of high-definition, so our intuitive feeling is that there will be graininess on the screen when displaying images, and the pixel shape is more obvious, so the resolution is slightly lower.
Secondly, the brightness of LED is higher than that of LCD. This is because it is mainly used outdoors and is set to cope with strong sunlight, but when used indoors, the high brightness becomes its disadvantage, because the brightness is too high, it is very difficult to watch. It is dazzling, but if you reduce its brightness, its gray level will also decrease, and the contrast will decrease, which directly affects the display effect. Finally, the stability of the LED is not as good as that of the LCD. After a long time of use, the LED lamp beads will fall off and the lamp will die, so it will affect the viewing experience to a certain extent.
The LCD splicing screen is mainly suitable for indoor viewing, whether it is viewed from a distance or at a close distance, there`s no effect on viewing; while the LED screen is mainly used outdoors, if it is used indoors, it is not suitable for close viewing. We suggest that if you need high-definition and multiple computer signals to display different content, it is better to use an LCD splicing screen. If you only display some single greetings, pictures, etc., you can also use an LED screen.
