Abstract

Local dimming (LD) has been selected as the next mainstream display technology for automotive. The advantages over current edge‐lit LCDs and AMOLEDs are significant. Nevertheless, there are still many issues to be addressed. It must meet tough automotive requirements and safety standards and display automotive HMIs with high contrast and circular structures. The fault tolerance with HMI is much lower compared to displaying natural contents like that of TVs. Such an LD display is a tradeoff between performance like power saving and visual quality at one side and cost at other side. To lift this tradeoff, three methods need to be worked on and combined.
