  • Patent number: 12185602
    Abstract: A display device comprises a substrate; a circuit array layer comprising pixel drivers, data lines, first dummy lines, and second dummy lines; and a light emitting array layer. The display area comprises middle, first side, and second side regions. The data lines comprise first, second, and third data lines disposed in the middle, first side, and second side regions, respectively. The first dummy lines comprise a first data detour line disposed in the first side region and adjacent to a part of the second data line, and auxiliary lines. The second dummy lines comprise a second data detour line configured to connect the first data detour line to the third data line, and additional lines. The auxiliary lines comprise a bias auxiliary line to which a bias power is applied; and a second power auxiliary line to which a second power is applied.

  • Patent number: 11842685
    Abstract: A pixel includes: a light emitting element; a first transistor generating a driving current flowing from a first power line to a second power line; a second transistor being turned on in response to a fourth scan signal; a third transistor being turned on in response to a second scan signal; a fourth transistor being turned on in response to a first scan signal; a fifth transistor being turned on in response to a third scan signal; a sixth transistor being turned off in response to a first emission control signal; a first capacitor; and a second capacitor. A period in which the second transistor is turned on and a period in which the third transistor is turned on do not overlap with each other.
