Samsung patents stacked display chips for better color

Patent drawing
Patent drawing from the official filing.

Samsung describes a display design where each pixel uses a single chip containing three stacked layers of light-emitting material. These layers are arranged vertically to produce different colors, such as red, green, and blue, within one small area.

Why it mattersThis approach could make screens thinner and more efficient by combining color layers into one component rather than placing them side-by-side.

In the filing’s own words

A display apparatus includes a display substrate including a plurality of pixel areas, and a plurality of light-emitting device chips on the display substrate and respectively corresponding to the plurality of pixel areas, where each of the plurality of pixel areas includes three subpixel areas, each of the plurality of light-emitting device chips is over the respective three subpixel areas, each of the plurality of light-emitting device chips includes a stacked structure in which a first light-emitting structure, a second light-emitting structure, and a third light-emitting structure are stacked in a first direction on the display substrate, and the first light-emitting structure, the second light-emitting structure, and the third light-emitting structure are configured to generate light of different colors from each other.

What exactly they claim (claim 1)

1. A display apparatus comprising: a display substrate comprising a plurality of pixel areas; and a plurality of light-emitting device chips on the display substrate and respectively corresponding to the plurality of pixel areas, wherein each of the plurality of pixel areas comprises three subpixel areas, wherein each of the plurality of light-emitting device chips is over the respective three subpixel areas, wherein each of the plurality of light-emitting device chips comprises a stacked structure in which a first light-emitting structure, a second light-emitting structure, and a third light-emitting structure are stacked in a first direction on the display substrate, and wherein the first light-emitting structure, the second light-emitting structure, and the third light-emitting structure are configured to generate light of different colors from each other.
