Abstract：

In　this　study,　the　STM32　microcontroller　is　used　to　drive　a　passive　matrix　(PM)　Micro-LED　through　two-wire　serial　transmission　and　row-column　integration.　STM32　exhibits　superior　properties,　including　simple-to-operate,　cost-friendly,　and　flexible　programming.　Moreover,　it　has　a　lower　cost　and　more　straightforward　implementation　for　testing　the　quality　of　the　device　and　realizing　the　graphics.　In　this　design,　the　connection　between　the　STM32　and　the　PM　array　is　realized　by　an　LED　driver　board　and　flexible　printed　circuit　(FPC)　structure.　The　two-wire　serial　protocol　and　row-column　integration　are　adopted,　which　not　only　optimizes　the　circuit　structure　but　also　avoids　coupling　problems.　Compared　to　the　existing　structures,　it　is　more　concise　that　only　four　connecting　wires　are　required　to　transmit　data　in　display　devices　of　any　resolution.　Besides,　the　problem　of　graphics　distortion　is　solved　through　two　buffers　to　form　a　data　handshake.　Using　this　method,　the　blue　PM　array,　which　has　a　resolution　of　48　×　48,　a　refresh　rate　of　60　Hz,　a　pixel　size　of　300　μm,　and　a　luminous　area　of　50　μm,　is　successfully　realized.　In　addition,　p-metal　fractures　caused　by　the　bulge　in　the　p-lines　are　also　resolved　by　adding　the　GaN　as　a　raised　substrate.　©　Published　under　licence　by　IOP　Publishing　Ltd.
