Mobile LED Takes the Lead in Automotive Applications

Mobile LED has been adopted as backlight for automotive displays such as HUDs, dashboards, in-vehicle infotainment systems and rearview mirror displays. Some LED producers also introduced conceptual applications of external automotive lighting with mobile LED.

According to industry sources, some automotive LED suppliers have delivered sample products of mobile LED backlight display module to OEM for validation. Meanwhile, mobile LED packager also showcased a conceptual mobile LED taillight application which could show information for alarming other road users.

In comparison with the rival technology, OLED, mobile LED has the advantages of lower cost and higher reliability. Adopting OLED displays for interior display systems would be too pricey for mid-range cars and thus has limited its impacts on LEDs. Moreover, OLEDs are sensitive to UV lighting and its lifetime is thus limited for external applications. This is the Achilles heel of OLED for automotive application as reliability and stability are crucial for vehicles. For the reasons, currently OLED technology has difficulties to compete with LEDs in the automotive market.
