    Abstract: A sensor-embedded display panel includes a substrate, a light emitting element on the substrate and including a light emitting layer, and a light absorption sensor on the substrate and including a light absorbing layer arranged in parallel with the light emitting layer along an in-plane direction of the substrate. The light absorbing layer is configured to absorb light of a red wavelength spectrum, a green wavelength spectrum, a blue wavelength spectrum, or any combination thereof. The light emitting layer includes a first organic material and the light absorbing layer includes a second organic material. A difference between respective sublimation temperatures of the first and second organic materials is less than or equal to about 150 °C, wherein each sublimation temperature is a temperature at which a weight reduction of 10% relative to the initial weight occurs during thermogravimetric analysis under an ambient pressure of about 10 Pa or less.

    Abstract: An image sensor may (300) include a first photo-sensing device (100) on a semiconductor substrate (200) and configured to sense light of a first wavelength spectrum, and second (210) and third (220) photo-sensing devices integrated in the semiconductor substrate and configured to sense light of a second and third wavelength spectrum, respectively. The first photo-sensing device may overlap each of the second and third photo-sensing devices in a thickness direction of the semiconductor substrate. The second and third photo-sensing devices do not overlap in the thickness direction and each have an upper surface (210p, 220p), a lower surface (210q, 220q), and a doped region (210d, 220d) therebetween. The third photo-sensing device includes an upper surface deeper further from the upper surface of the semiconductor substrate than the upper surface of the second photo-sensing device and a doped region thicker than the doped region of the second photo-sensing device. The image sensor may omit the first photo-sensing device.

    Abstract: A device includes a first electrode and a second electrode, an active layer between the first electrode and the second electrode and a plurality of auxiliary layers between the first electrode and the active layer. The auxiliary layers include first and second auxiliary layers, the first auxiliary layer proximate to the active layer, the second auxiliary layer proximate to the first electrode. An energy level of the active layer, an energy level of the first auxiliary layer, an energy level of the second auxiliary layer, and a work function of the first electrode become deeper sequentially or shallower sequentially.
