In the last issue, I gave you some popular science on the characteristics of LED light pole screens, but in fact everything has two sides. Today, the editor will tell you about the shortcomings of LED light pole screens, hoping to be helpful to everyone~
1. The contrast is low
0 Relatively speaking, the color contrast of LED display screen is average, so when displaying more colorful images, the effect it displays is not very bright, especially when reducing its brightness, the entire screen will be gray, not as rich in color as the LCD screen.
2. Clarity Generally, the clarity of the
LED display is determined by the resolution, and the resolution is determined by the density of the lamp beads. The smaller the lamp beads in the same area, the higher the resolution, and naturally the clearer it will be when displaying the image.
So some LED displays with large spacing are not as clear as small spacing, but even the minimum spacing LED displays have a sharpness that still does not reach the height of the LCD screen, especially when viewed close, there will be mosaic phenomena, so it is not suitable for viewing too close. If you want to achieve better clarity, you can only try to choose a small spacing product.
3. The lights are prone to die, and the after-sales rate is high. The lamp beads of the
LED display often fall during transportation, installation and use, resulting in the occurrence of individual pixel points not illuminating, which will affect the overall image display effect. If you want to repair it, you can only use professional technicians to go to the door for welding or replacement, which increases after-sales and later costs.
So the advantages and disadvantages of LED displays are quite obvious. We should also know this when choosing. How to play to its advantages and at the same time weaken its shortcomings as much as possible is what we want.
OK! That’s all for today’s editor’s sharing! See you next time ~
