Samsung patents display layers using magnesium or zinc additives
Samsung has filed a patent for a display device that uses light-emitting elements with specific semiconductor layers. The design adds magnesium or zinc to the second semiconductor layer of at least one of the three color subpixels to adjust how the light is produced.
In the filing’s own words
Provided is a display device including a first light-emitting structure including a first light-emitting element, a second light-emitting structure including a second light-emitting element, and a third light-emitting structure including a third light-emitting element, wherein the first light-emitting element, the second light-emitting element, and the third light-emitting element respectively includes a first semiconductor layer of a first conductivity type, an active layer, and a second semiconductor layer of a second conductivity type that are sequentially stacked, and at least one of the second semiconductor layer in the first light-emitting element, the second semiconductor layer in the second light-emitting element, and the second semiconductor layer in the third light-emitting element includes a magnesium (Mg) dopant or zinc (Zn) dopant.
What exactly they claim (claim 1)
1. A display device comprising: a first light-emitting structure comprising a first light-emitting element; a second light-emitting structure comprising a second light-emitting element; and a third light-emitting structure comprising a third light-emitting element, wherein the first light-emitting element, the second light-emitting element, and the third light-emitting element respectively comprises a first semiconductor layer of a first conductivity type, an active layer, and a second semiconductor layer of a second conductivity type that are sequentially stacked, and at least one of the second semiconductor layer in the first light-emitting element, the second semiconductor layer in the second light-emitting element, and the second semiconductor layer in the third light-emitting element comprises a magnesium (Mg) dopant or zinc (Zn) dopant.
