the framework for post-maintenance is easier. the product's utilization rate is increased since after five years of usage, you only need to change the module power supply (only the module needs to be replaced in the same series). the approval process for customers is significantly shortened by the fact that the same product from the m series can be assembled with various pitches to produce a mixed assembly effect. additionally, because the cabinets with various pitches are all the same size, the size and weight of the entire screen are unaffected.
