Problems solved by technology

[0006] The working voltage of the OLED screen is constant, generally 4-5V, and when there is a circuit failure, the voltage will rise, the OLED screen will become very bright, and then the OLED screen will be burned out, and the voltage will exceed the safety limit. The higher the voltage, the shorter the time from when the OLED screen is highlighted to burning out; therefore, generally OLEDs have a safe voltage, and the safety voltage of different OLED screens varies according to the device structure. Generally, when the voltage of the OLED screen is greater than the safe voltage After a period of time, the screen body will be burned

Abstract

The present application discloses an organic optoelectronic device, comprising a substrate, and a first electrode layer, an organic functional layer and a second electrode layer sequentially formed on the substrate; There is an over-electric confinement layer in parallel with the organic functional layer, and the over-electric confinement layer is formed of a pressure-sensitive material. In the present application, an over-electricity limiting layer connected in parallel with the organic functional layer is provided between the first electrode layer and the second electrode layer of the organic optoelectronic device. The resistance of the electrical confinement layer becomes smaller, allowing the current to pass through the over-electric confinement layer without damaging the organic optoelectronic device. When the voltage returns to normal, the resistance of the over-electric confinement layer returns to infinity, and the organic optoelectronic device can work normally.

Description

technical field [0001] The present disclosure relates to the technical field of organic optoelectronics, and in particular, to an organic optoelectronic device. Background technique [0002] Organic optoelectronics is an emerging research field formed by the intersection of many disciplines such as organic chemistry, physics, information electronics science and materials science.
