未来的家庭影院形式更加多样化,除了普通家庭影院外,还有计算机家庭微型影院(HCPC),利用计算机输出图像和声音信号而用大型显示器或投影机来显示图像的大型家庭影院。因此,在介绍视频图像及其显示时,不能不谈到计算机及其显示器。此外,在谈到高清晰度电视机时,许多人都喜欢用计算机的显示器来作比对,认为要达到近似计算机显示器点距的电视机,才能够得上高清晰度电视机。除了对这个问题存在不同看法之外,还有一些问题,比如,对于为什么对计算机显示的图像不提清晰度而只讲分辨率,显示器与电视机在图像显示特点上有何不同,显示器的分辨率与清晰度之间存在什么关系等。因此,根据计算机在家庭影院中的作用和读者对显示器存在的问题,本文对这方面也作一些分析和讨论。作为计算机的显示器,目前以传统的阴极射线管(CRT)显示器为主,近年也有少量时尚的液晶显示器加入。因为液晶显示器和等离子电视在前面的文章中已经介绍过,所以在这里不再专门介绍,而只以传统的阴极射线管显示器为例来讨论计算机显示器中的有关问题。
The future of home theater is more diversified. In addition to the normal home theater, there are also HCPCs, large home theater that uses computers to output images and sound signals and display images on large displays or projectors. Therefore, in introducing video images and their display, we can not but talk about the computer and its display. In addition, when it comes to HDTVs, many people prefer to use computer monitors for comparison. They think that TV sets that reach the dot pitch of a computer monitor can get HDTVs. In addition to the different views on this issue, there are some issues, such as the resolution of why the computer displays the image without mentioning the resolution, the display and the TV in the image display features are different, the resolution of the display What is the relationship between rate and clarity? Therefore, based on the role of the computer in home theater and readers’ problems with the display, this article also makes some analysis and discussion in this respect. As a computer monitor, the current cathode ray tube (CRT) display is currently the main, in recent years, there are a small number of stylish LCD monitors to join. Because LCD monitors and plasma TVs have been introduced in previous articles, they will not be discussed here anymore. Instead, the traditional cathode ray tube monitor is used as an example to discuss computer monitor issues.
