  • Patent number: 12159572
    Abstract: Discussed is a display device in which a photo transistor that senses light from a light-emitting element is disposed in a separate wiring substrate from a panel unit in which the light-emitting element is disposed. Thus, the photo transistor is used as a component of a compensation unit that compensates for a difference between luminance of pixels based on a sensing result of the light from the light-emitting element.
