摘　　要：针对平板电视(显示器)亮度均匀性采用两种测量方法其测量结果存在差异,以某品牌47吋液晶电视为测量对象,通过实验室多次测量,并选取其中一组实验数据进行计算分析。实验结果表明:采用移动式测量法测出的亮度值普遍高于定点式测量法,亮度均匀性也明显要大,以该测量对象为例,平均亮度增加约12cd/m2;亮度均匀性增加3%~4%。Aimed at brightness uniformity of flat panel TV(display),two measurement methods are used of which the measurement results are different.A 47" LCD TV of a brand is taken as the measurement object.Measurement is carried out for many times in which a group of experimental data is selected for calculation and analysis.The experimental results show that the brightness value measured by mobile measurement method is generally higher than that measured by fixed-point measurement method.Also,the former brightness uniformity is obviously greater.For this measurement object,the average brightness increases by about 12 cd/m2;the brightness uniformity increases by 3%~4%.
