  • Publication number: 20240267504
    Abstract: An optical see-through display apparatus includes an image output module, a display panel, an optical shutter panel to adjust a transmittance of an external light for each of R, G, and B colors. The display apparatus includes an optical sensor to measure a color of the external light. The display apparatus includes a processor that generates R, G, and B shutter data through a first compensation algorithm. The first compensation algorithm is operated to: compare a color of a mixed virtual image with a color of a target mixed virtual image, and when a color difference therebetween is a threshold value or less, designate a transmittance of the optical shutter panel as a candidate transmittance, and select a candidate transmittance implementing the mixed virtual image most similar to the target mixed virtual image, and generate the R, G, and B shutter data corresponding to the selected candidate transmittance.

  • Publication number: 20240215297
    Abstract: A light emitting device is described, which has a first encapsulation film enclosing an outside and a top surface of a light emitting diode. The first encapsulation film comprises an organic thin film of a fluorine-based polymer and an inorganic material infiltrated into a void of the fluorine-based polymer and linked chemically to the fluorine-based polymer. Optionally, a second encapsulation film can be disposed between a substrate and the light emitting diode. The encapsulation film provides a moisture barrier, while being flexible. Since the encapsulation film provides improved barrier properties to moisture and the like, the light emitting device can maintain good current density, luminous efficiency and luminance. The light emitting device can be a display device, a lighting device, a touch screen, etc.
