  • Patent number: 11686980
    Abstract: A display panel including a first substrate, a second substrate, a display medium layer and a sealant is provided. The second substrate is assembled with the first substrate. The display medium layer is disposed between the first substrate and the second substrate. The sealant is disposed between the first substrate and the second substrate, surrounds the display medium layer and includes a continuous one-piece pattern, wherein the continuous one-piece pattern includes a first segment and a second segment, and a difference between a width of the first segment and a width of the second segment is greater than or equal to a third of the width of the second segment.
    Type: Grant

  • Patent number: 11036091
    Abstract: A display panel may have a first region and a second region encircled by the first region. The display panel may include first substrate, second substrate, sealant, conductive layer, and display medium layer. The first substrate may have a first recess in the first region. The second substrate may be disposed opposite to the first substrate. The sealant may be disposed between the first and second substrates, and may be received by the first recess. The conductive layer may be disposed on the first substrate, cover the first recess in a conformal manner, and be interposed between the first substrate and the sealant. The display medium layer may be disposed between the first and second substrates and may be encircled by the sealant. A thickness of the sealant may be larger than a distance between the first substrate and the second substrate in the second region.

  • Patent number: 10684514
    Abstract: A display panel includes a first substrate and a second substrate assembled together with a sealant, and the resultant assembly encloses a display medium layer. An organic alignment layer and an inorganic alignment layer are disposed between the first substrate and the display medium layer. A first gap exists between the inorganic alignment layer and the sealant, and the organic alignment layer is located in the first gap. The inorganic alignment layer may contact the display medium layer, and the organic alignment layer may be in contact with the display medium layer in the first gap. A portion of the organic alignment layer may overlap the inorganic alignment layer. The inorganic alignment layer may be coated with a coating of hydrophobic molecules. The display panel may further include an opposite organic alignment layer and an opposite inorganic alignment layer between the second substrate and the display medium layer.
