The 2014 Nobel prize in Physics has been awarded to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura, for their invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources. In fact, red, green and blue (RGB) light emitting diodes were developed before 80's decade. Then, this has emerged as the efficient white light source based on array technology. For instance, an incandescent lamp consumes 60 W electrical power while a similar white LED needs only 6 W. It leads to a significant global energy saving. The other potential applications are high quality displays and monitors.
Furthermore, GaN LED has opened a window to develop the UV and deep UV LEDs that are very useful sources for compact spectrometers.
On the other hand, the Nobel Prize in Chemistry was dedicated to Stefan Hell of the Max Planck Institute for Biophysical Chemistry, Germany, and W. E. Moerner of Stanford University, USA, along with their colleague Eric Betzig of the Howard Hughes Medical Institute, USA, for " the development of super-resolved fluorescence microscopy".
It is delightful that both Nobel prizes in Physics and Chemistry are allocated to light and its applications.
What is your opinion? Particularly, which criteria are essential and deterministic to select the Nobel laureates.
Its help to improve the developments in LED lights and TV Displays for better resolution and Magnification. Its a Fabulous Invention.. Congrats and Best wishes to Winners..
Here is very useful information about Nomination and Selection of Nobel Laureates in each field of science as well as the Lists of Nobel Prizes and Laureates:

The development of super-resolved fluorescence microscopy, which brings optical microscopy into the nano-dimension, using this technology for visualization, researchers are ebale to see details of how HIV shape-shifts to enter T-cells, opening a clear development path to a vaccine capable of blocking HIV infection and this would improve human health.
