1、 Small spacing LED display screen: the performance of small spacing LED display screen is very eye-catching. Due to the fundamental difference in luminous principle and structure, small spacing LED products can not only realize seamless splicing, but also have a very wide color gamut and excellent color performance. These are not comparable to DLP and LCD, and have fast response speed, no ghosting, drag and other problems. It is almost a rewriting of the previous indoor large screen.

2、 DLP splicing screen: DLP is stable. In terms of splicing gap and mirror reflection, it performs better than LCD, but it can not be compared with small spacing; In terms of resolution and heat generation, it is not comparable to liquid crystal display, but also better than small spacing. Overall, the overall performance of DLP is "moderation", which is basically good except for the bottom brightness.

3、 LCD splicing screen: the advantages and disadvantages of LCD are also obvious. The biggest disadvantage is that the splicing seam is too large. Even the 1.8mm splicing seam is within the visible range of the naked eye, which has an impact on the overall visual performance. Secondly, the picture is greatly affected by external light, and the problem of easy reflection also needs to be solved. However, it still has great advantages in resolution, heat generation and maintenance, and the indoor display has low requirements for brightness. In addition, the price is low and the maintenance cost is not high. LCD still has obvious advantages in indoor display and has become the mainstay in the large screen splicing market.

Over the past two years, small spacing LED display products have been widely popular in the field of high-end large screens. They are the first choice in various summits, on-site display of press conferences, large command centers and other fields. They even began to enter cinemas and exist as movie screens. These are undoubtedly based on the display effects of small spacing products, such as good picture integrity and strong color expressiveness. However, before we are excited about this, we still need to focus on the same obvious defects in the indoor application of small spacing LED displays.
