新型军用头盔微晶显示器

A NEW MICRO LIQUID CRYSTAL DISPLAY FOR USE IN MILITARY HELMETS

液晶显示器以其高清晰度、低功耗、重量轻和无辐射等一系列优异性能发展十分迅速。本文介绍了一种采用虚拟显示技术研制的新型军用头盔微晶显示器 ,主要用于单兵系统中数字图像、数据和文字信息的传递 ,通过头盔显示器士兵可看到计算机产生的图形数据、战场地图、敌方情报、己方位置等信息。该显示器选用动态向列液晶材料 ,将液晶显示器 (LCD)微晶片紧贴到集成电路硅片上 ,由这些电路直接驱动微晶材料 ,并用发光二极管 (LED)作光源 ,使红、绿、蓝点光源按域顺序在微晶显示器上产生全彩色图像。该微晶显示器还利用人眼的视觉原理 ,设计特殊光学系统 。

Liquid-crystal display has seen very rapid development due to its excellent properties, vid. its high definition, low power consumption, light weight, no radiation et al. The paper introduces a new micro liquid crystal display (Micro-LCD) for use in a military helmet adopting the virtual-display technology. It is used to convey messages of digital image, data and text for the individual's system. Through it can be seen the information in figures, maps of the battleground, his and the enemy's positions etc. The kind of micro-LCD uses a dynamic array liquid crystal material, where as the micro liquid crystal piece closely pasted onto an integrated circuit silicon slice. Through the electric circuits, the liquid crystal materials are directly driven. It uses the LED as the illuminant, and lets the R, G, B light source to produce the full-colored images on the micro-LCD according to order. The micro-LCD also includes a special optical system according to the principle of vision of human eyes. So a visual image can be seen.
