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。
In order to obtain a very uniform high brightness, it is recommended to use a tilting LED array and flat-bottomed reflector large backlighting system. Tilt LEDs rearrange the angular distribution of the optimized light source without having to design an optical configuration separately. The new backlight system is simpler than the traditional system. As a design paradigm, the LED has an optimum tilt angle of 10 ° on a 22in display, producing up to 85% uniformity and a 1.3 times wider color gamut than the commercial CCFL backlight color gamut.
