| Abstract: | It designed lattice display module for colourful LED based on MBI5024, and gived its secondary develop- ment application program. The module used LED special 16 bit constant current driver MBI5024 for column to drive control of lattice data, 4/16 line decoder 74HC154 and PNP type power transistor for drive control of lattice. It used the three primary colors mixing principle, in which each pixel consists of red, green, blue three colors of LED combination for the modules, modular design, and the three primary colors was designed to highlight LED into 16 × 3 ×16 lattice module. At last, it gived applications of the module to form a color graphic display system. |
