问题 单项选择题

据美国《时代周刊》报道:美国施乐公司和3M公司签署了一项协议将产生像纸一样薄的显示器。纸张一直是用来显示信息的最好手段,它易于阅读、易于携带、易于储藏和不易破损,似乎同显示器毫无关系。而现在几十年前科幻小说中描述的梦想将要实现,科研人员将纸张的优点同我们每日接触的显示器结合起来,生产出“电子纸张” 。施乐公司同3M公司签署这项协议,准备将“电子纸张”生产商业化。 “电子纸张”的确切意思是什么正如你能想象到的:这片“纸”不仅可显示文章和图片,而且还可以像计算机显示器一样,对文章和图像进行任意刷新。如果电子纸张真的问世,报纸便可以实现自动刷新新闻、股票行情和体育成绩。 施乐的“电子纸张”是一张薄的、几乎透明的“纸张”,包含有几百万颗只有在显微镜下才可看清的珠子。珠子一面为白色,另一面为黑色,每颗珠子都浮在各自的充满油的小匣中,它可以任意旋转。一个充电器用来控制珠子的显示颜色——白色或黑色,既不像显示器的显示像素一样发光发热:也不像液晶显示屏一样,受观看角度的限制,它可以从任一角度看清。 “电子纸张”日前虽然还不能显示彩色并且还有诸多不尽如人意处,但研究人员正在努力工作力争提高“电子纸张”的解像度,同传统显示器进行竞争。从长远角度看, “电子纸张”的优点是不可否认的。

A.使纸张具有显示器的作用。

B.使显示器具有纸张的优点。

C.使显示器可以像纸张一样显示信息,并像纸张一样薄。
