系统是以STC12LE5404AD单片机作为主控器，通过3DU33光敏三极管，采集屏上的光信号，经适当的放大后反馈给单片机来控制在点阵屏上显示字符。整个书写过程和平常书写汉字一样流畅。而且能实现对字符的擦除、反显和移动，具有很大的实用价值。
繫統是以STC12LE5404AD單片機作為主控器，通過3DU33光敏三極管，採集屏上的光信號，經適噹的放大後反饋給單片機來控製在點陣屏上顯示字符。整箇書寫過程和平常書寫漢字一樣流暢。而且能實現對字符的抆除、反顯和移動，具有很大的實用價值。
계통시이STC12LE5404AD단편궤작위주공기，통과3DU33광민삼겁관，채집병상적광신호，경괄당적방대후반궤급단편궤래공제재점진병상현시자부。정개서사과정화평상서사한자일양류창。이차능실현대자부적찰제、반현화이동，구유흔대적실용개치。
The system is based on STC12LE5404AD microcontroller as the main controller,through 3DU33 phototransistor,optical signal acquisition on the screen,by properly amplified feedback to the microcontroller to control the characters displayed on the screen.The whole process of writing and writing Chinese characters as smoothly as usual.But also can realize the character of erasing,reverse display and mobile, and has great practical value.
