大屏幕HDTV显示器设计技术方案比较

Comparison among technical schemes for the design of large screen HDTV displays

重点讨论阴极射线管大屏幕ＨＤＴＶ显示器设计中的一些关键技术问题和总体设计中的技术发展趋势。以总体设计中的图像扫描格式选择的三种方案：单频技术方案、双频技术方案和变频技术方案为例，从技术、材料、成本、生产、市场适应面等方面进行了深入分析讨论。阐明由于电视技术、计算机技术和通信技术的互相融合，由此而产生的信息家电，因其显示的图像信息格式多样化，而决定了ＨＤＴＶ显示器设计中的变频技术是今后的主要发展趋势。

This paper mainly discusses some key technology programs during the design of Large screen HDTV Ready and the technology-developing trend in general design. For example we select three patterns for picture scanning lattice in general design which are mono frequency technology pattern dual frequency technology pattern and mutative frequency technology pattern and analyze and discuss in depth the technology material cost production market accommodation and so on. The paper leads to a conclusion that the mutual fusion of television technology computer technology and communication technology brings about information domestic appliance. The diversification of the picture information displaying format decides that mutative frequency technology is the main developing trend in the design of HDTV Ready.
