摘要

阐述了满足能源之星6.0的液晶显示器的背光源设计思路和方法。介绍了能源之星6.0的功耗标准以及测试方法

在原有51.1 cm(20.1 in)能源之星5.0液晶显示器的基础上

将原来低光效的3020-LED灯条更换为高光效的4014-LED灯条

使得背光源的功耗大幅度下降。对实际样品进行测试

整个液晶显示器的能源之星6.0功耗在14.34 W左右

远低于能源之星6.0对此款液晶显示器的最大功耗标准16.60 W。且对能源之星6.0功耗的预估值和实测值进行了对比和分析

发现预估值和实测值基本吻合。

Abstract

This paper presents the backlight design ideas and methods of liquid crystal display which meets Energy Star 6.0. The standard of Energy Star 6.0 power consumption and testing method were introduced

and we replaced 3020-LED bar with low luminous efficiency to 4014-LED bar with high luminous efficiency on 51.1 cm(20.1 in) liquid crystal display Energy Star 5.0

which made the power consumption of backlight significantly decreased. Tested data show the Energy Star 6.0 power consumption is about 14.34 W of whole liquid crystal display

which is much lower than the requirement value 16.60 W. Besides

the estimated and tested data were compared and analyzed

the result shows the estimated and tested data are almost same.
