The printed components include an electroluminescence display and the RFID antenna as well as the conductive paths ... In addition, the prototype contains a (conventional) micro battery keeping the electroluminescence light on even after the RF field has been removed. (EETimes) Wallpaper TV in the pipeline  Feb 25, 2009 The breakthrough is the result of improvements in organic electroluminescence (OLED) technology that gets the paper to emit light, according to Toshiba. Scientists had to find a way to increase the efficiency of existing OLED devices, such as television sets, that used the reduced-energy material. (Sydney Morning Herald -- World) Scientists Control The Spin Of Semiconductor Quantum Dot Shell States  Feb 11, 2009 In contrast with previous work, they resolve features in the electroluminescence (EL) spectra associated with the individual quantum levels (s-, p-, d-, and f- shells). As the bias current is increased, the shell states fill, and the EL from the QDs exhibits peaks characteristic of the shell energies, as labeled in figure 3.
