Local Dimming的背光与OLED比较


这是Local Dimming分区调光的背光,由成百上千颗单独的LED发光源组成。原则上可以控制每一颗LED的开和关,从而实现高对比度。
效果可以比肩OLED


Local Dimming是基于传统LCD基础上进行升级,所以在以下几个方面无法达到OLED的水平。

色域,OLED色域更广。

黑边,黑边更窄,

异形,能做大曲率异形,手机里面的瀑布屏就是OLED的。

OLED有它的缺点,寿命短,烧屏,成本太高。

 

所以,接下来很长时间是两者共存。长期来看等OLED解决了寿命问题,并且体量上去以后成本快速下降,OLED将会取代Local Diming

高端车型明年开始量产OLEDandLocal Diming产品,相比于传统LCD显示效果是质的飞跃。中低端品牌及车型也会快速铺开。所以现在各家OEM都在关注这两种技术的发展。
