昨天对于投影机市场而言是非常重要的一天,因为它标志着3LCD显示技术已经走过20个年头了。
有史以来首款标明使用3LCD投影显示技术的投影机是爱普生VPJ-700,该投影机亮度为100 ANSI流明,对比度为100:1,采用320×220的分辨率,这样的分辨率甚至不如现在的手机投影,但它依然是一款里程碑式的产品。
虽然投影技术在初始阶段还很简陋,但它经过多年的发展,已经初具规模了,比如现在您看到的爱普生的投影机产品,如PowerLite家庭影院6500 UB,其分辨率已经达到了1920×1080(全高清),亮度为1600 ANSI流明,对比度更是惊人,达到了75000:1。
“3LCD技术对于投影机行业的影响是深远的,3LCD能够提供鲜亮、自然的色彩和惊人的细节表现,几乎可以满足所有消费者和专业人士的每一种商业和娱乐应用需求”爱普生美国市场和发展董事Rajeev Mishra说到,“20周年庆典对于3LCD是一个机会,使其展示其巨大的价值,并得到领导者和业界的关注,继续推动这一产业向前发展。随着爱普生成为全球销量第一的投影机品牌,而且作为3LCD技术的领导者,爱普生为能够给消费者提供各种家用和商务投影产品而自豪。
