  • Patent number: 11069757
    Abstract: An OLED display panel providing color compensation without overdriving light emitting units includes the light emitting units and a substrate. Each light emitting unit includes a light emitting element and an electrochromic element. The light emitting element is on a side of the electrochromic element away from the substrate. The electrochromic element includes first anode and cathode, and an electrochromic layer between them. The light emitting element includes second anode and cathode, and light emitting material between them. A portion of the second anode is shared with the first cathode. The present disclosure also provides a method for making such OLED display panel. The OLED display panel uses the electrochromic elements for color compensation, reducing the energy consumption of the display panel and prolonging service life.

  • Publication number: 20150077687
    Abstract: A liquid crystal display device includes a first substrate, a second substrate opposite the first substrate, a fence structure, a plurality of cholesteric liquid crystals having mutually different color, and a medium layer. The fence structure is disposed between the first substrate and the second substrate to divide a space between the first substrate and the second substrate into different sub-pixel channels. The cholesteric liquid crystals are disposed into the sub-pixel channels to form different liquid crystal cells having mutually different colors. The medium layer is disposed in at least one of the sub-pixel channels to allow the liquid crystal cells to have mutually different cell gaps.
