回答1:

激光电视并不护眼的说法;激光电视的原理其实就是投影,对光源的要求很高,所以通常需要让室内保持一个比较暗的环境;
你想想看电视时,如果把灯全部关掉,背景就会很暗,小而亮的荧光屏和背景形成强烈的对比,时间一长,我们的眼睛就会感到疲劳,就像我们长时间用眼睛盯着灯光一样;在全黑的环境里看电视,还会增加体内甲种维生素的消耗。 而如果把屋里的灯全部开亮,在明亮的背景下,激光电视就显得灰暗,这样就会使图像的对比度和灰度等级下降,图像变得发淡而层次不清,大大地影响了收看效果,如果长期看这种不清楚的画面,也会影响我们的视力。
所以强烈建议别买激光电视!!

护眼应该不仅仅取决于达到人眼的光线亮度总和,而还应该与光束到达人眼后的亮度分布有关。比如,液晶屏幕发出100条光线,由于是直射进入人眼,每条光线的亮度是基本相等的。假设每条光线的亮度是“A”,那么这100条光线到达人眼的亮度总和就是100A。而激光电视是反射式呈象,即使发出200条光线,经过反射后,到人眼的每条光线的亮度会发生衰减,而且到达人眼的每条光线的亮度也不一样了。激光电视发出200条光线,经反射后到最终达人眼的可能只有150条,而且到达人眼的每条光线的亮度也不一样,这样,即使激光电视发出200条光线,到达人眼的总亮度与液晶相同也是100A,但由于其亮度分布是不均匀的,人眼看着就比较舒服。所以,液晶将亮度调低会给一种整个画面都发暗的感觉,会影响影像效果,而激光电视的亮度低,并不是所有光线整齐划一地调低,而是一种经过自然反射后的不均匀衰减,就是说有的高,有的低。

反射成像不刺眼:光源经过屏幕反射入眼类似自然光
久看近看不累眼:3米就可以看80+英寸大屏幕电视
色彩真实更护眼:画质超越液晶电视标准
没有辐射不伤眼:屏幕不通电、无辐射
其实搞清护眼原理很容易,但是去家电商城多走走才能真正体验到护眼效果究竟是什么样的,我当时就是去海信等好多品牌的柜台实际感受了一下,最终反复比较才定下的海信L6。

因为激光的原理相当于投影是采用的是折射光反射的画面,让用户看到的画面。所以没有直接的光源照射给用户。但是激光它本来就是有害的,虽然反射光没有危害,但是要直接接触激光的对人体的伤害是非常大的。一般小孩儿如果他并不表姐的话,直接接触到激光光源会对眼睛造成非常大的危害。在家里有小孩儿的用户,威胁隐患非常的高。其实现在液晶电视技术非常成熟。护眼和防蓝光做的都是非常到位的。如果在激光和液晶电视中选,不如买一个高端点的Q
LED电视来提升我们的生活品质。
