Organic Light Emitting Devices

The DPVBi (4,4′-bis(2,2-diphenylvinyl-1,1′-biphenyl) is a blue-light organic fluorescence doped material, which can be used as a hole barrier layer or a luminescent layer for fabricating organic light-emitting devices. A blue light device with stable color stability and high efficiency was prepared by co-doping blue light dye DPVBi and red light dye DCJTB as light-emitting layer. In order to prevent the infiltration of O2 and moisture inside the device from affecting the luminescence lifetime of the device, the device was encapsulated by atomic layer deposition. Since the driving voltage of the organic light-emitting device is generally above 5 V and the power consumption is low, in order to facilitate driving with a low voltage, a boost driving circuit based on the XL6009 chip was designed. The driver of the fabricated blue-light device was tested. The results showed that circuit had low-voltage drive characteristics and could be widely used in small toys, lighting, and portable devices. Through the test to achieve the desired goal, the requirements of low voltage and low energy consumption were realized, and the life of the light-emitting device can be tested, which has certain practicability and reference value.
