  • PHOTOSENSOR AND SENSOR EMBEDDED DISPLAY PANEL AND ELECTRONIC DEVICE
    Publication number: 20240057438
    Abstract: A sensor-embedded display panel includes a light emitting element on a substrate and including a light emitting layer, and a photosensor on the substrate and including a photosensitive layer extending at least partially in parallel with the light emitting layer along an in-plane direction of the substrate. The light emitting element and the photosensor include separate, respective portions of each of first and second common auxiliary layers each extending continuously as a single piece of material under and on, respectively, each of the light emitting layer and the photosensitive layer. The photosensitive layer may include a light absorbing semiconductor having a HOMO energy level having a difference of less than about 1.0 eV from a HOMO energy level of the first common auxiliary layer and a LUMO energy level having a difference of less than about 1.0 eV from a LUMO energy level of the second common auxiliary layer.

  • SENSOR EMBEDDED DISPLAY PANEL AND ELECTRONIC DEVICE
    Publication number: 20240008351
    Abstract: Disclosed are a sensor-embedded display panel and an electronic device including the sensor-embedded display panel. The sensor-embedded panel may include a light emitting element and a photosensor on a substrate. The light emitting element may include a light emitting layer and the photosensor may include a photosensitive layer in parallel with the light emitting layer along an in-plane direction of the substrate. The light emitting element and the photosensor include respective portions of a first common auxiliary layer. The first common auxiliary layer may be continuous along the in-place direction of the substrate and under each of the light emitting layer and the photosensitive layer. The photosensitive layer may include a fluorine-containing p-type semiconductor and a non-fullerene n-type semiconductor. The non-fullerene n-type semiconductor may form a pn junction with the p-type semiconductor.
