the Relation of Picture Definition with DTV Scaler, Concentricity and
Reproduction Ratio
摘要 针对基于电子束扫描的CRT电视显像管和基于像素寻址的LCD、PDP、DLP和LCoS等固有分辨力显示器，分析了它们显示数字电视图像的区别，重点研讨了固有分辨力显示器像素阵列、同心度、重显率和图像格式变换对重显图像清晰度的影响，给出了部分实验结果，提出了改善数字电视图像清晰度的建议。

Abstract：This paper aimed at CRT TV picture tube based on beam scanning and natural
resolution TV display such as LCD,PDP,DLP and LCoS based on pixel addressing,analyzed
their differences in displaying digital TV pictures, mainly discussed the impact of the pixel
array, concentricity, reproduction ration and picture format transformation of natural
resolution TV display on the definition of reproductive pictures.This paper provided some
experiment results, and gave some advice to improve digital TV picture definition.
Key words：DTV；display device；picture format；picture definition
