Organic light-emitting device

Abstract

The invnetion provides an organic light-emitting device, which includes a first substrate, a light-emitting structure layer, a first electrode layer, a second electrode layer, a second substrate, first conduction members, a second conduction member and protection structures. The light-emitting structure layer is disposed on the first substrate. The first electrode layer is disposed on the light-emitting structure layer and includes pad-like patterns. The second electrode layer is disposed between the light-emitting structure layer and the first substrate. The second substrate is adhered on the first electrode layer and includes a first circuit and a second circuit. The first circuit includes a continuous pattern and contact portions. The first conduction members are connected between the first circuit and the first electrode layer. The second conduction member is connected between the second circuit and the second electrode layer. The protection structures respectively form open circuits or close circuits between the contact portions and the continuous pattern.

Description

technical field [0001] The invention relates to a light emitting device. Background technique [0002] With the development of optoelectronic technology, the performance and quality of organic light-emitting devices are continuously improved to be applied in various fields. For example, large-area organic light-emitting devices can be applied in light-emitting devices that provide surface light sources. Generally, an organic light-emitting device has an anode layer, a cathode layer, and a light-emitting structure layer sandwiched between the anode layer and the cathode layer. The large-area organic light-emitting device may have uneven current distribution during operation, so local parts of the large-area light-emitting device may have current congestion. The phenomenon of current congestion will cause the temperature of local parts to rise, and even damage the components. In addition, due to the unstable electricity caused by the manufacturing process or the material it...

AI Technical Summary

Problems solved by technology

The phenomenon of current congestion will cause the temperature of local parts to rise, and even damage the components

In addition, based on the unstable electricity caused by the manufacturing process or the material itself, short circuits may occur in some parts

Under the electrode layer where the cathodes and anodes of different polarities cover the entire surface, a local short circuit or a single-point disconnection will cause damage to the entire component
