Abstract: A gamma voltage generator includes a reference gamma selector, a reference gamma converter, and a gamma curve adjuster. The reference gamma selector selects a top reference gamma voltage and a bottom reference gamma voltage that are between first and second reference voltages. The reference gamma converter converts the bottom reference gamma voltage to a conversion reference gamma voltage based on the top reference gamma voltage. The gamma curve adjuster generates a plurality of grayscale gamma voltages based on the conversion reference gamma voltage and the top reference gamma voltage.

Abstract: A display device may include a first substrate, a second substrate, a light emitting structure, a seal member, a seal structure, a pad electrode, and a connection wire. The second substrate may overlap the first substrate. The light emitting structure may be positioned between the first substrate and the second substrate. The seal member may be positioned between the first substrate and the second substrate. The seal structure may be spaced from the seal member. A section of the seal member may be positioned between the light emitting structure and the seal structure. The seal structure may be positioned between the seal member and the pad electrode. The connection wire may electrically connect the seal structure and the pad electrode.
