Abstract

The invention discloses an organic light-emitting diode device, comprising: an anode, an anode, and an organic emitting layer arranged in the cathode and the anode, the organic emitting layer includes a multilayer functional film layer; any adjacent multilayer functional film layer A diffusion layer is arranged between at least two functional film layers, and the diffusion layer dissociates metal ions, and the metal ions diffuse into the functional film layers adjacent to the diffusion layer for trap states in the functional film layer disposed adjacent to the diffusion layer are filled. The organic light-emitting diode device of the present invention can fill the trap states of organic molecular materials, reduce the Joule heating effect caused by the organic light-emitting diode device to get rid of the trap state to the carrier, so as to improve the service life and luminous performance of the device. Effect. In addition, the invention also discloses a display device with the organic light emitting diode device.

Description

technical field [0001] The invention relates to the field of organic electroluminescence, in particular to an organic light emitting diode device capable of improving luminous performance and service life and a display device with the organic light emitting diode device. Background technique [0002] Organic light emitting diode (OLED), as a new type of display technology, has become the mainstream trend in the display industry. Compared with Liquid Crystal Display (LCD), it has low power consumption, fast response, large viewing angle, wide color However, the problems of service life and luminous performance have always been a major technical problem of OLED. Please see figure 1 , figure 1 is the service life curve of OLED devices in the prior art. like figure 1 As shown, along with the increase of the OLED device service time (Time) ( figure 1 The value on the horizontal axis), the current brightness (L) and the initial brightness (L) of the OLED device 0 ) between t...
