RGB三色纯激光光源-晋煤激光
    LRGB    

       LRGB激光显示技术是以红、绿、蓝(RGB)三基色激光为光源的显示技术,区别与激光荧光色轮显示技术通过激光激发荧光色轮上的
荧光粉,从而形成不同颜色光源。 LRGB
作为最理想的光源显示技术彻底突破前几代显示技术色域空间的不足,同时完全继承数字时代的高
分辨率、数字信号等特征,细致地再现客观世界,实现人类有史以来最完美
的色彩还原,提供更具真实、震撼的图像表现力。



    宽色域    

       LRGB显示技术带来的色域比Rec.709色域标准还大,是目前国际显示NTSC色彩标准的2倍。传统显示设备只能再现人眼所见颜色的
35%,而LRGB三色纯激光显示技术可覆盖90%以上。因此LRGB显示技术所呈现的色彩更丰富,更真实。
 


    Laser True Black    
 
      LRGB显示技术其独有的特征是Laser True Black(激光纯黑),由于激光光源本身全通全断的特性以及光路的全密封设计,使得
Laser True Black技术可展现2万:1静态对比度和10万:1动态对比度。显示质量的金标准之一就是对比度,高对比度是图像清晰
和细节表现的保证。传统显示设备亮度越高,对比度越低。而LRGB显示技术可实现真
“黑色”显示,且对比度不随亮度变化。

    更高亮度    
 
    LRGB显示技术带来的高亮度是其他光源显示技术所不及的。纯激光光源的紧凑性以及其大的光功率密度使得纯激光投影显示设备可以
很容易达到高亮度,通过增加激光
光源模组数量,亮度可以无限制提高。而传统投影显示设备目前可显示的最高亮度为35000lm。由于激
光光源的窄色谱特性(单色性高),在相同标称亮度下,三色纯激光
投影机可以带来远远高于传统灯泡投影机的视觉亮度。

    长寿命    
 
       传统投影机所使用的灯泡的寿命指全部生产的灯泡,经过一段时间的工作,有50%的数量出现包括闪烁、不能稳定工作、不能点亮、物理破裂等故障,这个时间定义为灯泡的寿命。传统大功率汞灯寿命最高3000小时,氙灯700小时,输出功率衰减严重,不能长时间连续工作;
       LRGB激光投影机的光源在2万小时的衰减仅仅小于20%,因此激光光源使用寿命可达2万小时以上,输出功率稳定无衰减,可实现7天24小时连续工作。纯激光投影机每天8小时开机可以使用5-6年,与传统灯泡投影机和单色荧光轮投影机相比无需更换灯泡与荧光轮,因此大幅降低了后期的维护成本。


    环保节能    
 
       研究表明,传统灯泡在工作时,产生的能量中只有一部分是可见光,接近50%的能量以红外线和紫外线的形式辐射出来。长时间高能量的红外线和紫外线会影响投影机电子元器件的寿命,紫外线对人体的健康也有较大影响。此外,由于灯泡投影机光源所消耗的能量仅有一多半为有效可见光,因此浪费的能量也较多,导致系统的效率较低。纯激光投影机则基本上不产生红外线和紫外线,而且激光光源的发热量低,与普通灯泡投影机和单色激光投影机相比,具有更高的电光转换率。纯激光显示设备能耗是传统显示技术的1/3,生产过程中无废气,废水和废渣排放,绿色环保。
 
    Phosphor Free    

       LRGB显示技术采用三色纯激光光源,无需荧光轮产生其他颜色的光用于显示,系统结构也不含旋转荧光轮设备。荧光轮解决方案的激光投影系统内含旋转的荧光粉色轮,蓝色激光器轰击荧光粉产生绿色、红色光。因此,到达屏幕的光束失去了激光本征特性,从而不会产生散斑问题。但是由于其对工艺与环境要求高且系统不稳定,在显示画面方面,由于是单DLP色彩精准表达与亮度都不及LRGB三色纯激光显示技术。
