无论是手机还是液晶电视,凡是以LED为背光源的消费类电子产品不断地追求越来越小的背光源的尺寸,以匹配日益变薄的显示器,而且要求LED背光系统制造商用更少数量的LED实现更佳的性能,而且把系统做得更纤细。本文探讨的就是如何在不牺牲亮度以及均匀性的前提上,用背光所需的最少的LED来实现“更薄”的目的。 Whether it is a cell phone or a LCD TV, any consumer electronics product that uses an LED as a backlight continues to pursue smaller and smaller backlight sizes to match increasingly thinner displays, and requires LED backlighting system manufacturers to use a smaller number of LED to achieve better performance, but also to make the system more slender. This article explores how to achieve the “thinner” goal with the minimum number of LEDs required for backlighting without sacrificing brightness and uniformity.
