英文摘要：

LED industry has developed rapidly in recent years in China. LED applications has also become more and more widely. Recently, LED began to be used in backlight and will gradually replace the traditional CCFL. This paper focused on the impact of the performance of LED backlight under the different conditions, such as measuring distance, viewing angle, the average number of uniformity, and looks forward to the stand- ard of measuring methods of LED backlight published as soon as possible.
