Abstract
Provided is a display apparatus including: a first substrate; a first electrode disposed on the first substrate; an organic emission layer disposed on the first electrode and configured to generate light; a ferromagnetic electrode disposed on the organic emission layer and configured to control a spin of the light; a second electrode disposed on the ferromagnetic electrode, the second electrode opposing the first electrode; a polarizer disposed on the second electrode and configured to selectively transmit and convert at least part of the light, the polarizer comprising at least two laminated layers; and a second substrate disposed on the polarizer, the second substrate opposing the first substrate.

A display apparatus, comprising:
- a first substrate;
- a first electrode disposed on the first substrate;
- an organic emission layer disposed on the first electrode and configured to generate light;
- a ferromagnetic electrode disposed on the organic emission layer and configured to control a spin of the light;
- a second electrode disposed on the ferromagnetic electrode, the second electrode opposing the first electrode;
- a polarizer disposed on the second electrode and configured to selectively transmit and convert at least part of the light, the polarizer comprising at least two laminated layers;
- and
- a second substrate disposed on the polarizer, the second substrate opposing the first substrate.
A method of driving a display apparatus, the method comprising:
- generating light;
- passing the light through a ferromagnetic electrode to convert a polarization state of the light;
- passing the light through a second electrode;
- passing the light through a λ/4 phase retardation layer, thereby converting the light into right-circularly polarized light;
- converting the light to vibrate up and down;
- passing the light through a linear polarization layer;
- and
- passing the light vibrating up and down through a second substrate to enable a display of an image.
A method of driving a display apparatus, the method comprising:
- generating light;
- passing the light through a ferromagnetic electrode to convert the light into right-circularly polarized light;
- causing the light to separate into first light and second light, the first light passing through a second electrode, and the second light being reflected from the second electrode;
- converting the second light into left-circularly polarized light;
- passing the second light through a retardation layer;
- converting the passed second light into right-circularly polarized light;
- reflecting the second light from a first electrode;
- converting the reflected second light into left-circularly polarized light;
- passing the second light through the retardation layer;
- converting the second light into right-circularly polarized light;
- passing the second light through the second electrode;
- superposing the first light and the second light in the form of the right-circular polarized light to generate third light;
- passing the third light through a λ/4 phase retardation layer, the superposed third light being the right-circular polarized light;
- converting the third light to vibrate up and down;
- passing the third light through a linear polarization layer;
- and
- passing the light through a second substrate to enable a display of an image.
