Which brand of LED display is good?

Basically, there are only a few companies that do well in LED display, such as Liard, Zhou Ming, Lian Jian, Li Qiang Jucai and Shanghai Sansi. These are listed companies, and their business scope is very wide, not only focusing on LED display. Therefore, the expansion mode mainly depends on the following channels. There is also a long-standing and powerful unlisted company, Nanjing Luopu, which belongs to China Electric Power Branch and has the background of central enterprises. It is the earliest LED display manufacturer and drafter of industry standards in China. The main business of the whole company is also LED display, which is very dedicated and the market personnel are very stable. Basically, the manufacturer goes directly to get the project, and there is no need for a dealer. The LED display screens of Wanda, Longhu, Sunac and other shopping malls are basically theirs. Their fist products, such as the sky screen and the ball screen that can play 8K video, are spectacular and industry-leading. My friend is doing market expansion in the southwest of Lop. I heard it's not bad.
