Reliability of OLED display encapsulation technology in automotive applications
Organic light emitting diode(OLED)as a new generation of display technology,compared to the liquid crystal display(LCD)has many advantages,including wide color gamut,high contrast,low power consumption and lightweight,etc.There is a replacing trend of LCD in the field of consumer electronics such as smart phones,tablets,monitors,televisions.With the increasing intelligent demand of new energy vehicles,and the display,as the final output unit of the human-machine interface of the electronic system in the intelligent cabin,has the trend of large screen and multi-screen.Considering the limitation of space in the cabin,the light and thin self-emitting OLED has obvious advantages,especially its characteristics of fabricating on flexible substrates,which makes OLED displays more suitable for multi-form flexible display schemes.At present,OLED displays are rarely used in vehicle applications,which is mainly limited by the poor environmental reliability of OLED devices.This paper analyzes the methods of improving the environmental reliability of OLED display by improving the thin film encapsulation in three aspects:improving the barrier ability,improving the stability and improving the heat dissipation ability,which provides reference for the subsequent application of OLED display in automotive intelligent cabin.
