基于MBI5024的多彩LED点阵模块设计及应用

Design and Application Lattice Display Module for Colourful LED Based on the MBI5024

设计了基于MBI5024的多彩LED点阵显示模块并给出其二次开发应用方案.采用LED专用16位元恒流驱动器MBI5024为点阵数据列驱动控制,4线/16线译码器74HC154及PNP型中功率三极管为点阵行驱动控制,利用三基色混色原理,模块中的每个像素点都由红、绿、蓝三种颜色的LED组合而成,模块化设计,将三基色高亮LED制成16×3×16点阵模块.并给出了利用该模块组建彩色图文显示系统的应用方案.

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.
