| titleOfInvention | Six-color intermixed and spectrally tunable parallel white light organic electroluminescent device and preparation method thereof |
| abstract | The invention discloses a parallel type white light organic electroluminescence device with six-color intermixing and adjustable spectrum; the device comprises a substrate/anode layer/hole injection layer/hole transport layer/light-emitting layer/electron transport layer/ The stack structure of electron injection layer/cathode layer; the light-emitting layer adopts a parallel structure of six light-emitting films, and the six films correspond to six light-emitting colors. The cathode layer can use separate strip electrodes, and each strip electrode corresponds to the light-emitting layer. In a strip-shaped light-emitting film, the cathode layer is divided into three groups to form three terminals, corresponding to red light, green light and blue light. Three independent controllers control the working voltage of these three groups of light-emitting devices, so as to obtain Different luminescence spectra. The prepared device is driven by a direct current voltage, and high-efficiency white light with a color rendering index suitable for various application occasions can be obtained. The present invention can solve the problem that the spectrum of the traditional white light device changes with the increase of use time. The device manufacturing process is simple, the cost is low, and the power consumption is low. |
