The System Behind Projection HDTV高清晰度投影系统背后

Projection HDTV has 4 fundamental components.4投影清晰度已基本组成. These are the projector, screen, control panel, and the sound system.这些都是投影机、屏幕、控制面板、音响系统. These parts can be purchased separately or installed as a built-in feature.这些部件可单独购买或安装一个内置的特色.

The projector is the main part of the projection HDTV.投影机的主要部分是投影高清晰度电视节目. This is the portion where all the system is centered.这是该系统核心部分是各. It applies two different methods in forming a screen image.它适用两种不同的方法形成屏幕形象. The first is the Transmittive.一是透射. With this approach, a shine of light passes through an image.这种做法,光普照穿过形象. This is generally used in LCD panel TVs.这是普遍采用的液晶屏电视机. The second one is the Reflective; wherein a light bounces off an image through a reflective chip.二是反光;其中轻型客踢形象透过反光片. Microelectromechanical systems or MEMS (such as digital micromirror device and grating light valve) and liquid crystal on silicon or LCOS are two of the latest byproducts of reflective projection.微电子机械系统或微机电系统(如数码微镜装置、光栅光阀)和液晶硅或LCoS显示两项最新的投影反射副产品.

The two methods are then collected by a lens.那么这两种方法都收集了镜头. This will be then enlarged and displayed into the TV screen.那么这将放大到电视屏幕展示. The one device responsible for both the Transmittive and Reflective projection is the “optoelectronics” found inside the projection HDTV.一个负责的透射装置及反光投影是"光电子"内投影高清晰度电视节目.

The projection HDTV’s screen is comparable to those found in theaters.投影清晰度的屏幕是媲美找到便车. The control panel of a projection HDTV is usually included as a built-in feature.控制小组通常包括了高清晰度电视投影内置特征. It functions along with a remote control.但随着遥控功能. Its core units vary according to its primary use.其核心单位随其主要用途. If you are using your projection HDTV as a home theater system, the central hub will be the audio and video receiver.如果你是用你的HDTV作为家庭影院投影系统中部枢纽将影音接收机. However, if it is used in a conference room, the core will be the audio & video receiver and a computer.不过,如果是用一间会议室,核心是音视频接收机和电脑.

When it comes to the projection HDTV’s speakers, advanced sound systems are applied.说到投影清晰度的发言,先进的音响系统是应用. These include the Home THX, Dolby Surround Sound, and the Dolby Digital EX.这包括民政thx、杜比环绕声、杜比数字恩.

One of the most popular projection HDTV item is the 47-inch Samsung Tantus HCL473W.其中最受欢迎的项目是高清晰度电视投影47英寸三星tantushcl473w. Its main features include the Auto Perfect Focus, Multi Digital Convergence, HD Fine Pitch Screen, and the 1000 Lines Resolution.其主要特点包括:自动完美的焦点,多数码收敛,房屋优良草地屏、1000线决议案.
