近年,世界彩电技术向两极发展:微型化与大型化。大屏幕彩电视角宽、清晰度高、画面与制式多、音质好,故对彩管、整机电路提出了更高要求,应是我国彩电发展方向之一。 目前发达国家大屏幕彩电的社会拥有量,美国为37％、日本为47％,而我国不足3％,可见市场前景广阔。行家予测,近期国内大屏幕彩电市场将是:沿海城市高于内地城市,将占总需求的60～70％;而大城市需求集中,占总数60～70％。
In recent years, the world’s color TV technology has developed toward two poles: miniaturization and large-scale. Large-screen color TVs are wide in angle, high in definition, have many pictures and systems, and are of good sound quality. Therefore, higher demands are placed on the color tubes and the whole circuit, which should be one of the development directions of color TV in China. At present, the social ownership of large-screen color TVs in developed countries is 37% in the United States and 47% in Japan, but less than 3% in China, showing a broad market prospect. Experts predict that the recent domestic large-screen color TV market will be: coastal cities higher than inland cities, will account for 60-70% of total demand; and large cities demand concentration, accounting for 60 to 70% of the total.
