LCD Innovations vs. OLED Performance for Automotive Applications

Abstract

LCDs are today’s workhorse for automotive displays. In recent years, some premium OEMs started to ship cars with OLED displays. The advantages of OLEDs compared to LCDs are short response time at low temperature (relevant for e-mirrors) and perfect black at night as well as highly curved and transparent versions. Replacing edge-lit backlight of LCDs by FALD (full array local dimming) results in highest luminance at acceptable halo. Furthermore, LCDs have a large supply chain, which results in competitive cost. Well-known challenges of OLEDs deal with high luminance and temperature sensitivity, which can result in reduced lifetime (LT) incl. Burn-In. Challenges and solutions for LCDs and OLEDs such as halo measurements and viewing angle performance will be discussed more in detail. Latest automotive demonstrators show the potential of micro-LEDs and electrically pumped Quantum Dots (QD) displays. Both have the potential to outperform LCDs and OLEDs.
