长虹无疑是国内电视业界之王,凭借雄厚的实力、经过近二年的内部整合,近来在市场上显现出王霸之气,51PDT18就是其新近推出的一款精密显像背投电视机。该机采用三枪式高亮度投影管,光学系统的镜头具有低发射率,进一步提高了图像对比度。在电路设计上应用数字变频技术、逐行扫描技术与运动补偿电路以及亮度、对比度、色彩、聚焦等自动补偿电路,使图象闪烁与行间闪烁降至极低。51PDT18达到1250线的高清晰度性能,并且获得比一般背投电视机更佳的亮度、对比度、层次丰富等特
Changhong is undoubtedly the king of the domestic television industry, with its solid strength, after nearly two years of internal integration, recently appeared in the market, the king of the gas, 51PDT18 is its recently introduced a precision imaging rear projection television. The machine uses a three-gun high-brightness projection tube, the lens of the optical system has a low emissivity, further improving the image contrast. In the circuit design of digital frequency conversion technology, progressive scan technology and motion compensation circuit and brightness, contrast, color, focus and other automatic compensation circuit, the image flicker and line flashing down to very low. 51PDT18 to 1250 lines of high-definition performance, and get better than the average rear projection TV brightness, contrast, rich levels and other special
