Enhanced light emission from top-emitting organic light-emitting diodes by optimizing surface plasmon polariton losses [PDF]

, 2015
We demonstrate enhanced light extraction for monochrome top-emitting organic light-emitting diodes (OLEDs). The enhancement by a factor of 1.2 compared to a reference sample is caused by the use of a hole transport layer (HTL) material possessing a low ...

Algorithms for longer OLED lifetime [PDF]

ACM Journal of Experimental Algorithmics, 2007
We consider an optimization problem arising in the design of controllers for OLED displays. Our objective is to minimize the amplitude of the electrical current flowing through the diodes, which has a direct impact on the lifetime of such a display.
