Abstract

The embodiment of the invention discloses an organic light-emitting display device, a manufacturing method thereof and organic light-emitting display equipment. The organic light-emitting display device comprises a first electrode and a second electrode which are arranged oppositely; a first light-emitting layer and a second light-emitting layer are arranged between the first electrode and the second electrode; the first light-emitting layer is arranged close to the first electrode and is prepared from the composing materials including a first subject material and a first object material; the second light-emitting layer is arranged close to the second electrode and is prepared from the component materials including a second subject material and a heat activation delay fluorescent material. In the embodiment of the invention, the heat activation delay fluorescent material can reduce electron injection obstruction, and an exciplex is difficult to generate; the first light-emitting layer and the second light-emitting layer are arranged, so that a light-emitting center position can be flexibly regulated, the efficiency of the device is improved, and the service life of the device is prolonged; and in addition, the strongest radiation wavelength of the device is fixed after the light-emitting center position is determined, so that the problem that the light color, the brightness and the color error are changed because of offset of the light-emitting center position, is solved.

Description

technical field [0001] Embodiments of the present invention relate to organic light emitting display technologies, and in particular to an organic light emitting display device, a manufacturing method thereof, and an organic light emitting display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display device is a self-luminous display device with an organic light-emitting layer located between the cathode and the anode as the illuminant. It has ultra-thin, high brightness, high luminous efficiency and good shock resistance. Advantage. The constituent materials of the organic light-emitting layer usually include a host material and a guest material. After a voltage is applied to the cathode and anode, the triplet exciton energy of the host material is transferred to the triplet exciton energy of the guest material, thereby realizing electroluminescence. [0003] In the organic light-emitting layer of the existing organ...
