An Inorganic Light Engine: Monolithically Integrated LED Arrays as Projection Sources


Presenter: Vincent Lee of Columbia University


Wednesday, February 1, 2011

Columbia University

Members and non-members of SID are welcome



LEDs are the brightest controllable light source and can achieve a high optical power densities exceeding 40 W/cm2.  The high brightness enables the use of LEDs, if patterned into an array, as a light and pattern generation source for projection displays.  Compared with current projection display systems, these arrays would allow for significant improvements in power consumption and overall system efficiency.  I will present the current state of development of our proof-of-principle LED arrays.  In addition, I will discuss the use of laser-crystallized thin film silicon transistors integrated with these LEDs for active matrix arrays.


Speaker’s Bio:

Vincent Lee graduated with his B.S. in electrical and computer engineering at Rutgers University and M.S. in electrical engineering at Columbia University in 2007 and 2009 respectively. He is currently a graduate student at Columbia University working in the Columbia Laboratory for Unconventional Electronics (CLUE) on integration of compound semiconductors with laser crystallized thin film silicon transistors.
