摘　　要：在低碳节能成为全球热门话题的背景下,采用LED背光源已成为当前液晶电视背光应用主流,以降低功耗为目的的动态背光调节技术应运而生。本文设计一款基于FPGA(现场可编程门阵列)的液晶电视动态LED背光调节系统,结果测试表明降低功耗最高可达48%。Under the background that low carbon and saving energy become the global hot topics, the LCD TV backlight which is made of LEDs is the mainstream absolutely at present. The technology of backlight dynamic adjusting which could greatly reduce the power consumption has emerged as the times require. Designed a dynamic regulation system based on FPGA for LCD TV backlight, Test results show that the system is able to save up to 48% power consumption.

关 键 词：背光源 液晶电视 降低功耗
