    Abstract: A display device includes first and second initialization voltage sources and first and second pixel circuits. The first initialization voltage source provides a first initialization voltage. The second initialization voltage source provides a second initialization voltage less than the first initialization voltage. The first pixel circuit includes a first organic light emitting diode. The second pixel circuit includes a second organic light emitting diode with an organic material having a band gap different from a band gap of an organic material in the first organic light emitting diode. The first pixel circuit is coupled to the first initialization voltage source and the second initialization voltage source. The second pixel circuit is coupled to a single initialization voltage source.

    IPC: H01L27/32

    Abstract: A display device includes a substrate including a pixel region and a peripheral region. A plurality of pixels is disposed in the pixel region of the substrate. Each of the plurality of pixels includes a light emitting element. Data lines and scan lines are connected to each of the plurality of pixels. A power line is configured to supply power to the plurality of pixels. The power line includes a plurality of first conductive lines and a plurality of second conductive lines intersecting the plurality of first conductive lines. The plurality of second conductive lines is arranged in a region between adjacent light emitting elements of the plurality of pixels. At least some of the plurality of second conductive lines extend in a direction oblique to a direction of extension of the data lines or the scan lines.

    Abstract: A display device includes a substrate including a display area and a peripheral area disposed around the display area. The peripheral area includes a bending region and a contact region adjacent to the bending region. A first connection line includes a first portion disposed in the contact region, and a second portion disposed in both the bending region and the contact region, and including a first layer and a second layer. At least part of the second layer of the second portion overlaps the first layer of the second portion. In the contact region, the first layer of the second portion is electrically connected to the first portion, and the second layer of the second portion is electrically connected to the first layer of the second portion.
