Sony patents display design that blocks moisture from reaching pixels
Sony describes a display panel where the active screen area is surrounded by a separate ring of organic material. This outer layer acts as a barrier to stop moisture from entering the delicate light-emitting parts of the screen.
In the filing’s own words
For example, there are provided a display device, electronic equipment, and a manufacturing method of the display device capable of preventing entry of moisture or the like into an effective pixel region. A display device includes a drive substrate including an effective pixel region and a peripheral region between the effective pixel region and an outer edge portion, in which the effective pixel region includes a plurality of pixels, each of the pixels includes a first electrode, a second electrode disposed opposite to the first electrode, and a first organic layer provided between the first electrode and the second electrode and including a light emitting layer, and the peripheral region includes a second organic layer separated from the first organic layer included in the pixel.
What exactly they claim (claim 1)
1. A display device comprising a drive substrate including an effective pixel region and a peripheral region between the effective pixel region and an outer edge portion, wherein the effective pixel region includes a plurality of pixels, each of the pixels includes a first electrode, a second electrode disposed opposite to the first electrode, and a first organic layer provided between the first electrode and the second electrode and including a light emitting layer, and the peripheral region includes a second organic layer separated from the first organic layer included in the pixel.
