Light is one of life’s necessities and most people would not even want to imagine living in a world without light. In particular, artificial light provides massive benefits to human lives and it is one of the most important technologies that have been invented.
Let’s take a closer look at the history of lighting and LG OLED light.
History of lighting
In the 1780s, the first scientifically made oil lamp, called the Argand Burner, was patented in England by the Swiss born Aimé Argand. It was the first time lamps had changed in over a thousand years. However, it had a greater oil consumption compared to the earlier lamps because it emitted 10 times more light.
Approximately 10 years later, a Scottish Engineer called William Murdock began experimenting with gas lighting by distilling gas from coal for illumination. This was the first step in the production of the gas light.
Later, an arc lamp named the YABLOCKOV Candle was used for street lighting in Paris and other European cities. Interestingly, the YABLOCKOV Candle was inspired by Humphry Davy’s invention, which used a battery of 2,000 cells to create a 100-millineter arc between 2 charcoal sticks.
The incandescent lamp, which passes an electric current through a wire filament to produce light, was invented in late 19th century by Thomas Edison and sir Joseph Wilson Swan, independently. Later, the two inventors formed the Edison & Swan United Electric Light Company.
In the 1890s, Nikola Tesla experimented with the first Neon and fluorescent lights to light his laboratory and after 22 years, a Neon sign type advertisement was seen in Paris.
In the 1970s, the first commercial compact fluorescent lights which used 75% less energy than incandescent light bulbs were invented by Edward E. Hammer in response to the oil crisis.
A Light-Emitting Diode (LED), which produces light by passing an electric current through a semiconductor was created in the 1920s, but it was not fully developed until Nick Holonyak, Jr. developed the first visible-spectrum LED in the 1960s. In the early 1990s, Isamu Akasakic, Hiroshi Amano and Shuji Nakamura developed the first blue LEDs. By combining red, green and blue diodes, it could generate a bright white light.
In the 1980s, Ching W. Tang and Steven Van Slyke developed the world’s first working OLED at Eastman Kodak, and researchers at Pacific Northwest National Laboratory and the Department of Energy invented two technologies necessary to make flexible OLEDs in the early 2000s.
History of LG OLED light
With continuous experiments and efforts from researchers, including LG Display, lighting technology has developed, providing massive benefits to our daily lives. LG Display will continue this research and promise to produce high-end lightings.
