Dr. Ching W. Tang, who is known as the ‘father of OLED’, explained the merits of OLED displays at LG’s presentation and spoke about where he sees the future of the technology.
Without backlight and other auxiliary layers, the OLED display is fundamentally less complicated compared to LCD, and in time less costly to manufacture. I have no doubt, given its advanced features and superior performance – foldable, wearable, flexible and transparent, OLED is the display technology for the next generation.
if it's cost effective to use it, it will be used. That should keep oil under 60 or 70 for the next few years.
