  • Publication number: 20240397798
    Abstract: There is provided a display device, a display panel and a manufacturing method thereof. The display panel includes a driving backplane, a light-emitting layer, a first inorganic layer, a lens layer, an organic layer and a second inorganic layer. The light-emitting layer is arranged on a side of the driving backplane and includes a pixel definition layer and light-emitting devices. The first inorganic layer covers the light-emitting layer. The lens layer is arranged on a surface of the first inorganic layer away from the driving backplane, and includes lenses arranged as corresponding to the light-emitting devices. The organic layer covers the lens layer. A refractive index of the organic layer is smaller than a refractive index of the first inorganic layer and smaller than a refractive index of the lenses. The second inorganic layer covers the organic layer.

  • Publication number: 20240147779
    Abstract: A terminal device, a display apparatus, and a display panel and a manufacturing method therefor. The display panel comprises: a drive backplane, which has a display region comprising a light-transmitting display region and a main display region, the light-transmitting display region comprising a light-transmitting region; a pixel definition layer, which comprises openings including a first opening and a second opening; a plurality of light-emitting devices defined in the openings; and a color film layer. The opening spacing between two adjacent first openings satisfies a specific relational expression, thereby improving the light transmittance and also preventing cross-color.

  • Publication number: 20220102687
    Abstract: A display module has a display area. The display area includes a main display area and a sub display area. The display module includes: a display panel, a first color filter layer disposed at a light exit side of the display panel and located in the main display area, and a polarizing layer disposed at the light exit side of the display panel and located in the sub display area. The polarizing layer serves to change a polarization direction of at least part of external light entering an inside of the display panel, so as to prevent the at least part of the external light entering the inside of the display panel from exiting from the light exit side of the display panel.
