摘要
针对现有LED显示屏不能现场修改显示内容的缺点,设计了LED点阵书写显示屏的控制器,提出了一种新的控制方案:可手写输入修改显示内容,并实现"点亮、划亮、反显、擦除、连写多字、对象拖移和整屏显示"等书写显示功能.本系统由控制模块、点阵及驱动模块、光笔、液晶显示等组成.设计了硬件和软件,并制作了样机,试验调试结果表明,效果非常好.
As LED display screen showing contents cannot be modified instantly,LED display screen writing controller is designed.A new control method is proposed by modifying the displays by hand written input and the screen to achieve the results of ＂light up,draw light,anti-colordisplay,erasing,continuously write multi-characters,objects drag and full-screen display＂.The system consists of control module,dot matrix and the drivermodules,light pen and LCD.Hardware and software are designed.A sample is made and the test is conducted.The results show good effects.
