Choose a small-pitch model for a small-area screen, and choose a large-pitch model for a large area. For example, for an LED transparent screen of about 30 square meters, it is recommended to choose 3.91, not 9.26 or 15.6; for an LED transparent screen of more than 50 square meters, you can choose 9.26, and the budget is sufficient. Of course, the effect of choosing 3.91 is very clear, but the cost will be High, sometimes there is no need to spend more money. In addition, considerations need to be made based on the use environment and budget. For example, indoor and outdoor displays are different. Indoor display brightness is low, while outdoor display brightness requirements are high.
