OLED TECHNOLOGY MARKING MAJOR MILESTONE, BECOMING UBIQUITIOUS IN DEVICES

2017 is a significant milestone for OLED (organic light-emitting diode) technology – it will be 30 years since its introduction via a paper published by Ching Tang and Steven Van Slyke.
 
In brief, OLED utilizes an emmisive layer comprised of carbon-based thin-film that’s held between two charged electrodes.  There’s no backlighting which necessitates an extremely high contrast ratio. OLED technology is now frequently being used in mobile phones, digital cameras, PDAs, mp3 players, and more.Takatoshi Tsujimura, Ph.D., SID Fellow, SID Treasurer
 
2017 is a significant milestone for OLED (organic light-emitting diode) technology – it will be 30 years since its introduction via a paper published by Ching Tang and Steven Van Slyke.
 
In brief, OLED utilizes an emmisive layer comprised of carbon-based thin-film that’s held between two charged electrodes.  There’s no backlighting which necessitates an extremely high contrast ratio. OLED technology is now frequently being used in mobile phones, digital cameras, PDAs, mp3 players, and more.
 
And while OLED displays still represent a small percentage of the worldwide display market, they are poised for rapid growth.  Cambridge, UK-based market research firm IDTechEx, for instance, forecasts that annual global sales of OLED displays will grow from $16 billion last year to $42 billion by 2020.
 
"OLED displays can be lighter, they can be flexible, and they allow designers more leeway with the shape of their devices", said Guillaume Chansin, an IDTechEx senior technology analyst.  "Because they are manufactured on a plastic substrate instead of a glass one, OLED displays can make phone screens shatterproof or even foldable."
 
Tadashi Uno, a senior analyst at the market research firm IHS Technology, added that OLED displays provide significant advantages over LCDs in terms of weight, thinness, robustness and flexibility ; if manufacturers can develop a process that achèves high yields, I’m certain the whole display industry will shift to OLEDs."
 
Meanwhile, according to Chemical & Engineering News, commitments to OLED production are increasing.  Last November, LG Display announced a $9 billion investment in an OLED TV plant that will open next year.  And Applied Materials, which supplies precision manufacturing equipment, said last month that demand for tools to make OLEDs rose sharply last year.
 
Want to learn more about OLED displays ? Come to Los Angeles in May for Display Week 2017. During Display Week there will be a 30th anniversary celebration, attended by many of the pioneers who helped launch OLED.
