Who Invented OLED?

What is OLED?

OLED stands for Organic Light Emitting Diode. It is a type of display technology that is widely used in today's electronic devices such as smartphones, televisions, and digital cameras. Unlike traditional LED displays, OLEDs do not require a backlight to produce light. Instead, individual pixels emit light themselves, resulting in brighter, more energy-efficient displays with improved color accuracy and contrast ratio.

Early OLED Development

The development of OLED technology began in the 1970s, with early research conducted by scientists at Eastman Kodak and Philips. However, it wasn't until the 1980s that OLED technology started to gain serious attention. One milestone achievement during this time was the demonstration of a working OLED display by University of Michigan researchers in 1987.It was during this time that Ching W. Tang and Steven Van Slyke, researchers at Eastman Kodak, made significant breakthroughs in OLED technology. Tang and Van Slyke were able to produce an OLED that emitted green light, using a simple organic compound sandwiched between two electrodes. This achievement led to the development of a red OLED in 1989, which paved the way for the development of full-color OLED displays.

Discovery of Efficient Blue OLED

While green and red OLEDs had already been developed in the late 1980s, researchers continued to struggle with the development of an efficient blue OLED. Blue OLEDs were seen as the "holy grail" of OLED technology, as they were needed to produce full-color displays.In 1992, Ching W. Tang and Steven Van Slyke achieved a major breakthrough in the development of blue OLEDs. They discovered that by using a carefully crafted blend of two organic molecules, they could create a blue OLED with an external quantum efficiency of 5%. This discovery made it possible to create full-color OLED displays, which are widely used today in a range of electronic devices.In conclusion, while the development of OLED technology was a collaborative effort involving many researchers, it was the breakthroughs made by Ching W. Tang and Steven Van Slyke at Eastman Kodak that paved the way for the widespread use of OLED displays today. Their discovery of efficient blue OLEDs was a major achievement, which opened up new possibilities for display technology.

Who Invented OLED?

OLED technology has revolutionized the field of display technologies, bringing us brighter, more vibrant and energy-efficient displays that are flexible and bendable. Nowadays, OLED technology can be seen in almost all aspects of life, including smartphones, televisions, lighting, and even wearable devices. But who invented this amazing technology?

Patent and Commercialization

The creation of OLED technology was a combined effort by Professor Ching W. Tang, a chemist at the University of Rochester, and Steven Van Slyke, then a researcher at Kodak. Their research was initially focused on conventional LED displays in the early 1980s and moved to OLEDs shortly thereafter.

Kodak's Role and Patent Dispute

While Professor Tang and Van Slyke were both instrumental in the early research and development of OLED technology, Kodak's involvement in the development and maturation of OLED technology is also noteworthy. It was during Steven Van Slyke's tenure at Kodak that the company filed several key OLED patents, which were central to the company's efforts to commercialize the technology.

However, Kodak's OLED patents proved to be the center of controversy later on when they emerged as a major point of contention in a patent dispute with the University of Southern California, where former Kodak researcher Mark E. Thompson had taken up the post of professor. In 2001, research at the University of Southern California prompted Kodak to file a lawsuit against the university, claiming that it had infringed its OLED patent. The lawsuit was settled in 2009, but it demonstrated that Kodak's role in the development of OLED technology was not insignificant.

First OLED Commercialization

The first commercialization of OLED technology was small and happened in the early 2000s. The technology first gained attention in the high-end television market, with Sony being among the first companies to release an OLED screen. In 2008, OLED displays were introduced to mobile phone screens, with Samsung being the first company to feature OLED technology in their phones. OLED technology quickly became a popular choice for high-end smartphones, due to their energy efficiency and excellent bright color representation.

Recent Innovations and Future of OLED

Recent innovations in OLED technology have been focused on creating products with foldable displays and flexible screens that can be bent and curved. This technology promises to revolutionize the way we use displays, making them more versatile and rugged. Some companies have also been exploring the use of OLED technology in the health and wellness industry, using the unique properties of OLED screens to treat certain conditions.

The future potential for OLED technology is vast and spans many different industries. From lightweight, durable displays in the automotive industry, to medical devices and treatment products in the health industry, OLED technology is poised to transform many different aspects of our lives.


In conclusion, OLED technology was co-invented by Professor Ching W. Tang and Steven Van Slyke, with Kodak playing an important role in the commercialization and patenting of the technology. The ongoing innovation in OLED technology and its potential applications in various industries is proof of its solid future in the market.
