摘要
为获得非常均匀的高亮度,建议采用倾斜LED阵列和平底反射器大型背光系统。倾斜LED重新安排优化光源的角度分布,而不必另外设计光学配置。新式背光系统比传统系统的结构更简单。作为设计范例,在22in显示屏上,LED的最佳倾角为10°,产生的均匀度高达85%,色域比商用CCFL背景灯色域宽1.3倍。
Inclined LED array and flat bottom reflector for large-sized backlight system was proposed to obtain high brightness uniformity. Tilted LEDs rearrange the angular distribution of light source optimized without extra designing optical configuration. The novel backlight system is simpler in structure than the traditional ones. Optimum inclined angle of 10 degrees of LEDs on 22in panel as designed example yields the competitive uniformity of 85% and a color gamut of a factor of 1.3 wider than those of commercial CCFL backlight.
