Joint research and development of new achievements, effectively improve the efficiency of LED light-emitting

Recently, the United States RenssELaer Polytechnic Institute University in South Korea and the joint efforts of Electro-Mechanics company, published a new research results. The results of this study can improve the luminous power 18%, photoelectric conversion efficiency of 22%, which significantly reduces the efficiency of the problem.

According to the researchers, polarization mismatch can be significantly reduced by introducing a new quantum well. They replaced the GaInN/GaN layer in the active region of LED with GaInN/GaInN, so that the buffer layer of the active region has better polarization matching, thus effectively reducing the electron leakage and reducing the efficiency. In the CES 2009 consumer electronics show can be seen, LED LCD TV backlight has been widely used. If this technology can be applied, will further enhance the LED backlight LCD TV energy efficiency, reduce energy consumption.
