Abstract

The invention provides an organic light emitting diode device, a manufacturing method thereof and a display device, and belongs to the technical field of display. The problem that an existing top-emitting AMOLED cathode material is poor in light transmittance or conductivity can be solved. A first spacer on a second substrate in the organic light emitting diode device has an uneven structure, so that adhesion of an auxiliary electrode material is facilitated; the height of the first spacer is different from that of a main spacer, wherein the high spacer mainly plays a role in supporting, and when the device bears pressure, the high spacer can achieve supporting and pressure buffering functions so that an auxiliary electrode on the first spacer can be protected when making contact with a first electrode on a first substrate, the auxiliary electrode is prevented from being broken, and the conductivity of the whole first electrode is enhanced. The organic light-emitting diode device is suitable for various display devices.

Description

technical field [0001] The invention belongs to the technical field of display, and in particular relates to an organic light-emitting diode device, a preparation method thereof, and a display device. Background technique [0002] At present, organic light emitting diode (Organic Light Emitting Diode, OLED) devices are developing rapidly in the field of flat panel display with the characteristics of thinness, low consumption, high response, and high resolution, and their potential market prospects are favored by the industry. [0003] Top emission passive organic light emitting diodes (Active-matrix organic light emitting diodes, AMOLEDs) can effectively solve the problems of reduced aperture ratio and display brightness caused by complex TFT (thin film field effect transistor) compensation circuits. The microcavity effect existing in the structure of the top emission AMOLED device can also improve the color gamut of the AMOLED display screen and improve the display effect. ...
