Abstract

The invention discloses an organic light-emitting device. The organic light-emitting device comprises a substrate, and a first electrode, a luminous layer and a second electrode that are stacked on the substrate in sequence; the first electrode comprises an electronic control birefringent material film layer and multiple conductive film layers that are arranged in a laminated manner; and the conductive film layers are partially arranged on the same side of the electronic control birefringent material film layer. The organic light-emitting device provided by the invention can regulate and control the reflectivity of the first electrode through the electronic control birefringent material film layer for regulating and controlling a microcavity length so as to realize high luminous efficiency; a method for regulating and controlling the microcavity length through a multi-layer luminous layer structure in the prior art is also avoided; meanwhile, the device is simple in structure and mature in technology; and the production cost is effectively reduced and the product yield is improved.

Description

technical field [0001] The invention relates to the field of organic electroluminescence, in particular to an organic electroluminescence device. Background technique [0002] Organic Light-Emitting Device (English full name OrganicLight-EmittingDevice, referred to as OLED) is an active light-emitting device with low power consumption, wide color gamut, and thinner volume. It is expected to become the next generation of mainstream lighting and flat panel display technology. Organic electroluminescent devices mostly adopt a sandwich-type sandwich structure, that is, the organic layer is sandwiched between electrodes on both sides, holes and electrons are respectively injected from the electrodes on both sides, and transported in the organic layer, and form excitons after meeting. , exciton recombination luminescence. [0003] According to the different directions of light emission from the device, organic electroluminescent devices in the prior art are mainly divided into tw...
