3D显示技术凭借主动式快门3D眼镜与被动式偏振3D眼镜技术的高速发展,已经全面融入到家庭影院投影领域,各大投影机与投影幕厂家在推出全新一代产品之时都充分融入了3D的元素,家庭影院投影机会将主动式快门或被动式偏振技术纳入其中,并成为基本功能。家庭影院投影幕则在维持色彩还原度的基础上设法提高投影幕的增益。在3D家庭影院投影机技术发展方面,已经从早期的720p高清3D机型全面过渡到1080p全高清3D机型,随着HDMI 1.4传输标准的建立,完善地解决了对于3D信号支援较差的问题,可以完整兼容Frame Sequential(帧连续)、Frame Packing(帧封装)、Side by Side(左右并排)、Top and Bottom(上下并排)的3D传输信号格式,也就是能够支持蓝光3D、电视3D以及电脑3D等主流的信号源,使得3D家庭影院投影机开始进入到实用阶段。此外,由于制造成本以及技术难度等方面的优势,主动式快门眼镜技术更加受到投影机厂家的青睐,目前绝大部分的3D家庭影院投影机都采用了这种技术。但是由于技术上的限制,闪烁、左右眼图像串扰等问题依然困扰着众多用户,主动式快门3D技术还有待进一步的成熟。而被动式偏振眼镜技术也开始进入到家庭影院投影机领域,尽管目前这类投影解决方案仍然是建立在双投的方式上,构建成本相当高,普通消费者恐怕很难接受,但是其无闪烁感、低失真的立体影像确实令人难忘,期待将来能够降低建立成本,进入到主流投影机市场。在3D家庭影院投影幕方面,为了补偿由于3D信号传输以及3D眼镜的光损耗,各大投影幕厂商都通过对幕料的改良,增加幕布的增益之余也不会损害到画面的整体色彩准确度。下面将会就3D家庭影院投影技术进行全面的分析与讲解,涵盖了两种不同家庭影院3D技术之间的各个优势与限制、对投影幕的要求等多方面,同时也会介绍最新热门的3D家庭影院投影机,让更多的影音爱好者能够更深入地了解3D家庭影院投影技术上的细节以及主流3D家庭影院投影机的特点,掌握建立优秀的三维立体大画面的关键。
3D display technology with active shutter 3D glasses and passive polarized 3D glasses technology has been fully integrated into the field of home theater projection, the major projector and projection screen manufacturers in the launch of a new generation of products are fully integrated into the 3D elements , Home theater projectors incorporate active shutter or passive polarization technology and become the basic function. Home theater projection screen is to maintain the color reproduction on the basis of trying to increase the projection screen gain. In 3D home theater projector technology development, from the early 720p HD 3D models fully transition to 1080p Full HD 3D models, with the HDMI 1.4 transmission standard, the perfect solution to the problem of poor support for 3D signals Compatible with Frame Sequential, Frame Packing, Side by Side, Top and Bottom 3D transmit signal formats that support Blu-ray 3D, TV 3D, and PC 3D and other mainstream sources, making 3D home theater projectors began to enter the practical stage. In addition, due to the manufacturing cost and technical difficulty, the active shutter glasses technology is more and more favored by projector manufacturers. At present, most 3D home theater projectors adopt this technology. However, due to technical limitations, flashing, left and right eye image crosstalk and other issues still plagued many users, active shutter 3D technology remains to be further matured. The passive polarized glasses technology has also begun to enter the field of home theater projectors, although this type of projection solution is still based on the double-vote approach, the construction cost is quite high, the average consumer may find it difficult to accept, but its flicker-free , Low distortion of the three-dimensional video is really memorable, looking forward to the future can reduce the establishment of cost, into the mainstream projector market. In 3D home theater projection screen, in order to compensate for the 3D signal transmission and 3D glasses of light loss, the major projection screen manufacturers through the improvement of the curtain material, while increasing the screen gain will not undermine the overall color of the screen accurate degree. The following will be 3D home theater projection technology to conduct a comprehensive analysis and explanation, covering the two different home theater 3D technology between the various advantages and limitations, the requirements of the projection screen and many other aspects, but also introduce the latest popular 3D Home theater projectors, so that more video enthusiasts to more in-depth understanding of 3D home theater projection technology details and the characteristics of the mainstream 3D home theater projector, master the key to create excellent three-dimensional large screen.
