  • Patent number: 11929024
    Abstract: The organic light emitting display device is driven to be divided into a refresh frame when the data voltage is programmed in the pixel and a reset frame when the anode electrode of the organic light emitting diode is reset, and the data voltage is maintained to a first level during the reset frame. Accordingly, a separate stage for applying an on bias stress is not provided so that the bezel may be reduced.
    Type: Grant

  • Publication number: 20240079540
    Abstract: A display module includes a substrate, a first pixel circuit, a first light emitting element, a second pixel circuit and a second light emitting element. The first pixel circuit is configured to control the first light emitting element. The first pixel circuit is located inwardly from an edge of the substrate with respect to the first light emitting element.

  • Patent number: 10367045
    Abstract: Embodiments disclosed herein relate to an electroluminescence display device including a first electrode, a second electrode facing the first electrode, an emission layer between the first electrode and the second electrode, and a bank layer defining the emission layer. The bank layer may be disposed between the first electrode and the second electrode. The bank layer may include a first bank layer and a second bank layer. The second bank layer may include a black pigment. The first bank layer may be closer to the first electrode than the second bank layer, and the first bank layer may have a lower permittivity than the second bank layer.
