  • Publication number: 20250221280
    Abstract: A display apparatus in which a light-emitting device and a pixel lens are disposed in each pixel area is provided. An encapsulation structure can be disposed between the light-emitting device and the pixel lens of each pixel area. A lens passivation layer covering the pixel lenses and a lens dam surrounding the lens passivation layer can be disposed on the encapsulation structure. The lens dam can include a first region having a first width and a second region having a second width different from the first width. Thus, in the display apparatus, loss and deformation of the lens dam due to a process of forming the pixel lenses and/or the lens passivation layer can be prevented. Therefore, in the display apparatus, damage of the pixel lenses due to external impact and moisture can be effectively prevented.

    Abstract: A display apparatus having a light-emitting device and a touch electrode is provided. An optical pattern may be disposed on the light-emitting device. A side of the optical pattern may be sloped. A surface of the optical pattern opposite to the light-emitting device may be covered by an intermediate insulating layer. The intermediate insulating layer may be harder than the optical pattern. The touch electrode may overlap the side of the optical pattern. Thus, in the display apparatus, the surface defect of the optical pattern in the forming process of the touch electrode may be prevented.

  • Patent number: 11556016
    Abstract: A three dimensional (3D) display apparatus can include lenticular lenses between a display panel and a viewing angle control film. The display panel can have a curvature. The viewing angle control film can include a plurality of light-blocking patterns between a first control substrate and a second control substrate. A pitch and a height of the plurality of light-blocking patterns can be determined by a curvature radius of the lenticular lenses, a distance between the viewing angle control film and a set viewing region, and a length of the display panel corresponding to the set viewing region. Thus, in the 3D display apparatus, the quality of 3D images provided to a user can be improved.
