Sony patents light-emitting device with extended contact structures
Sony describes a light-emitting device design that improves how electrical connections are made around the active display area. The invention uses specific structures in the contact electrode that extend outward from the light-emitting region to increase the contact area with the main electrode.
In the filing’s own words
Provided is a light-emitting device capable of securing a carrier path in a direction away from a light-emitting region while increasing a contact area between a first electrode and a contact electrode. The light-emitting device includes a plurality of light-emitting elements in a light-emitting region, a contact electrode provided in a peripheral region located around the light-emitting region, and a first electrode extending from the light-emitting region to the peripheral region and connected to the contact electrode. The contact electrode includes a plurality of first structures at a portion where the first electrode is connected, and a plurality of the first structures extends in a direction away from the light-emitting region.
What exactly they claim (claim 1)
1. A light-emitting device, comprising: a plurality of light-emitting elements in a light-emitting region; a contact electrode provided in a peripheral region located around the light-emitting region; and a first electrode extending from the light-emitting region to the peripheral region and connected to the contact electrode, wherein the contact electrode includes a plurality of first structures at a portion where the first electrode is connected, and a plurality of the first structures extends in a direction away from the light-emitting region.
