0420 Supply of LED strip screens in Hefei, Anhui [Recommended quotation, manufacturer, maintenance, wholesale]

An independent unit of LED display screen that is determined by circuit and installation structure and has display function. Simply put, for the convenience of assembly and display, semi-finished products that leave the factory are usually provided in the form of display modules, which combine multiple display modules and display drivers together. Indoor screens are commonly known as "unit panels"; Outdoor screens are commonly known as "modules", which are then combined with several modules such as a chassis, fan, power supply, etc. to form a "box", often used for large full-color screens
