OLED Device Nearer To 3D Magic
Posted on Feb 25, 09 09:34 AM PDT
Eiji Shiko from the Japan Advanced Institute of Science and Technology has successfully developed an OLED device which is able to emits circularly polarized light in the visible light range, resulting in the possibility of 3D displays on OLEDs in the near future. In order to produce such a circular polarized light in the visible light range, one has to make sure that the spin state during the light emission process is controlled via injecting a spin-polarized carrier from the ferromagnetic negative electrode into the emission layer. When a magnetic field intensity of 3,000Oe is applied at room temperature, it seems as though light emission with a circular polarization degree of about 0.5% was observed.
