  • Publication number: 20240130164
    Abstract: A display device includes a substrate and a plurality of unit pixels disposed on the substrate. Each unit pixel includes a plurality of sub-pixels, a plurality of light sensing pixels, and a plurality of partition wall members. Each of the sub-pixels includes a light emitting element that emits light and a light emitting area from which the light is emitted. Each of the light sensing pixels includes a light receiving element that outputs a sensing signal corresponding to the light and a light receiving area that receives the light. In a plan view, each of the partition wall members surrounds the corresponding light receiving area and overlaps at least some of the sub-pixels.

  • Patent number: 8092926
    Abstract: An organic light emitting diode device includes an organic layer formed of a hole transport material or a hole injection material having a photocurable group. Therefore, the organic light emitting diode device can be formed using a wet process that is simple and can be used for a large substrate. Furthermore, the organic layer and an organic light emitting layer are less affected by a solvent. Thus, the lifespan of the organic light emitting diode device is increased and there is more freedom in selecting materials for the organic layer and the organic light emitting layer. A method of manufacturing the organic light emitting diode device is also disclosed.
