| Abstract: | 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. |
