摘　　要：得益于小间距发光二极管(Light Emitting Diode,LED)显示屏的无缝拼接和显示色彩自然真实的优势,小间距LED显示屏受到显示行业青睐,开始飞速发展。以主流的P0.9小间距LED显示屏为例,阐述此类印制线路板(Printed Circuit Board,PCB)的设计思路以及可能存在的问题,供广大设计人员参考。Thanks to the advantages of seamless splicing of small-pitch LED display screen and it displays true color, small-pitch Light Emitting Diode(LED) display screen is favored by the display industry. It begins to develop rapidly. Taking the mainstream P0.9 small pitch LED display screen as an example, this paper describes the design ideas and possible problems of this kind of Printed Circuit Board(PCB) for reference by the majority of designers.
