摘要
双色8×8点阵LED矩阵发光屏采用逐行扫描方式驱动,以8031单片机为核心,MAX7219作为行、列驱动器,完成了双色8×8点阵LED矩阵发光屏驱动板设计与制作,实现了LED显示器件的动态驱动。通过对驱动波形的测试与分析,加深了学生对显示像素4种状态(全选点,行、列半选点和非选点)的理解。通过对该实验系统功能的扩展,可以强化学生平板显示器件驱动技术方面的训练。
Two-color 8 × 8 LED matrix is driven by scanning one line at a time. Using 8031 as controller and MAX7219 as the row and column driver, the LED panel is demonstrated, and the dynamic display is obtained. The driving wave form can be measured and analyzed. The selected pixel, half-selected pixel and nonselected pixel are clearly indicated by the driving wave form. This experiment system can be extended to further intensify the technical training of the fiat panel display driver.
