A color-tunable and high-effective organic light-emitting diode device with forward-inverse structure as intelligent lighting display

In recent years, the tunability of solid-state light sources has become an ideal feature for the illumination and exhibition industries. However, the ability of spectral and intensity tunability independently is still crucial. In this paper, an integrated OLED device, serving as a conceivable solvent to illuminant utilized in the tunable luminous scheme, is put forward as the intelligent color displays. The manufactured OLED device consists of a forward and an inverted sub-cell, which allows the demand of different materials for device structure compared to devices composed of the same structure, thus realizing the requirements of high-efficiency, high-brightness, and easy-fabrication. Then, the working mechanism of this organic electroluminescent device is discussed and utilized with AC electrical signals to address each emitter cell independently for adjusting the corresponding color temperature and intensity. The functional structure using forward and inverse integration with AC-driven can be integrated into commercial power systems for various lighting situations, thus bringing potential development of future intelligent displays.
