Martin Schubert, a Rensselaer Polytechnic Institute student, has developed a new type of
light emitting diode (LED) that could lead to the widespread use of LED’s as light sources for liquid crystal displays (LCDs) which can be found on everything from computers and
televisions to cell phones and cameras. This is the first polarized LEd to be developed and this innovation could immensely improve LCD screens and pave the way for the next generation of ultra-efficient LEDs. Schubert, a doctoral student in electrical, computer, and systems engineering, has earned the $30,000 Lemelson-Rensselaer Prize for this innovation. The prize,which was first given in 2007, “is awarded to a Rensselaer senior or graduate student who has created or improved a product or process, applied a technology in a new way, or otherwise demonstrated remarkable inventiveness”.Schubert’s polarized LEd has the ability to have a better control of the direction and polarization of the light being emitted. Less energy is wasted when there is better control over the light because less light is scattered and more light reaching the desired location. Because of this, polarized LED is best suited as backlighting unit for any kind of LCD. The images that would be produced with focused light are more crisp, colorful, vibrant, and lifelike, and with almost zero motion artifacts.
