简介:2010年,3D潮流可谓锐不可挡,以主动快门式3D技术为代表的眼镜式3D电视大规模登陆市场,市场销售呈现开门红,预计全年全球销量将突破300万台,因此2010年可以称得上真正的"3D电视发展的开元之年"。眼镜的束缚似乎没有阻挡消费者对3D电视的欣赏热情,但冷静之余,我们却不得不面对眼镜式3D电视可能会对视力造成的不良影响,以及长时间观看所带来的头晕、恶心等不良感受,而且对近视眼患者因佩戴"双重"眼镜所带来的痛苦更是不可言状,因此,我们不得不承认,目前的眼镜式3D电视只能作为3D电视技术发展的过渡产品,而最终必然被成熟的裸眼3D电视技术所取代,裸眼3D显示将是未来3D电视技术发展的必然归宿。
