Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] see figure 1 , figure 1 It is a structural schematic diagram of the first embodiment of the organic light-emitting device provided by the present invention.

[0030] like figure 1 As shown, the organic light-emitting device 100 includes a substrate layer 110, a first electrode layer 120, a light-emitting layer 130, and a second electrode layer 140 stacked in sequence, and also includes a barrier disposed between the first electrode layer 120 and the l...

Abstract

The invention provides an organic light-emitting device, which comprises a base plate layer, a first electrode layer, a light-emitting layer and a second electrode layer, wherein the base plate layer, the first electrode layer, the light-emitting layer and the second electrode layer are laminated in sequence; the organic light-emitting device also comprises a blocking layer arranged between the first electrode layer and the light-emitting layer or between the second electrode layer and the light-emitting layer; the blocking layer comprises a light-emitting main body material; the triplet-state energy level T1 of the light-emitting material is not less than 2.5ev. As the organic light-emitting device which is provided by the invention is provided with the blocking layer comprising the light-emitting main body material, the light-emitting main body material has the quite high triplet-state energy level T1, and when being used as the blocking layer, can block the diffusion of triplet-state excitons; the annihilation of the excitons is reduced; therefore, the service life of the organic light-emitting device is prolonged.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic light-emitting device. Background technique [0002] Compared with LCD panels, AMOLED (abbreviation for Active-matrix organic light emitting diode, referred to as AMOLED) display panels have advantages such as self-illumination, simple structure, low cost, fast response speed, wide viewing angle, high color saturation, high contrast, and thinness. , more and more smartphones and wearable devices are beginning to use AMOLED panels. [0003] With the large-scale application, more and higher requirements are put forward for the performance of AMOLED, such as low voltage, high brightness, high efficiency, low energy consumption, long life and so on. Contents of the invention [0004] The invention provides an organic light-emitting device to solve the technical problem of short service life of AMOLED devices in the prior art. [0005] In order to solve the abo...
