| 摘 要： | 通过LVDS（低压差分信号）传输方案与单个LCoS（硅基液晶）分时分色显示，设计主电路与头盔结构分离的单LCoS硅片彩色头盔显示系统。利用Ahera公司的CycloneⅡ芯片作为数字逻辑控制，不但提高了系统集成度，更充分发挥了其内嵌LVDS传输特性，大大简化了头盔显示系统的电气结构，降低了头盔重量。测试表明，分离式头盔显示系统能够正常工作。

| Abstract: | With time divided display of single LCoS chip and LVDS transmission, the true color helmet display system of LCoS chip is separated into two parts, the main circuit and the helmet structure. A lot of advantages including higher system integration, simpler electronic connections and much lower helmet weight have been obtained through implementing digital logic control unit with Ahera＇s Cyclone Ⅱ FPGA chip, which fully takes advantage of its embedded LVDS transmission module. The helmet display system is proved to be working properly in practical use. |
