世界上最小的SVGA彩色显示屏上市

CyberDisplay SVGA LVS显示器的像素大小为11.25微方比平板电视使用的像素小1000倍。
通过置入单晶硅晶体管,Kopin公司 (美国麻州, Westboro; www.kopin.com) 宣称已成功研制出世界上最小的SVGA彩色显示屏。此款CyberDisplay SVGA LVS显示屏对角线长为0.44英寸,与公司现有的VGA显示器尺寸相同,但是此款显示器分辨率更高,达640 480像素。潜在的医疗应用包括内窥镜系统与视力辅助系统领域。

此款显示器使用的设计架构与大型LCD显示器相同,但其像素为11.25微方比平板电视机像素小1000倍。同用于手机等日常小型显示屏上的多硅晶体管技术相比,单晶体硅晶体管技术能提供更高的像素密度,尽管像素小,但可使图像更清晰。平板多金属层处理、液晶对齐纳米技术处理和盒间隙液晶组合处理进一步实现了研制进程。

此公司过去最小的SVGA彩色显示器对角为0.59英寸。与公司以前的小型SVGA显示器相比,电力消耗也随之从100mW降低至70mW。首席技术官Hong Choi指出,低电力消耗是此种尺寸大小显示器的本质特点。他说:这样小的显示屏可通过一种眼镜仪器使其在光学上放大,从而使图像更逼真。若要使这种仪器正常运作,必须是电池供电,因而显示屏不能消耗太多电量。

使用该显示屏的仪器与显微镜运作方式类似,用户通过镜头观测放大物体,在此情况下则是通过显示屏。按照Choi的说法,只有这样的仪器才能置于内窥镜系统中。他说:在现今的系统中,外科医生必须不时抬头才能观测到显示屏上的体内图像,连续上下扫视会占用时间并且会增大误差。高分辨率眼镜仪器可使外科医生无须移动头部就能看到清晰而又详细的体内图像。Choi补充说显示器尺寸小实现了仪器的轻盈便捷,这样外科医生只需在仪器(就像戴了一副眼镜)下方移动眼睛就可在正常视野内看清操作范围。

Choi表示Kopin过去的产品主要用于消费和军用市场,但是公司打算增加在医疗设备行业的份额。
