  • Patent number: 10858588
    Abstract: The present invention discloses a negative dielectric anisotropic liquid crystal composition, characterized in that the liquid crystal composition comprises one or more compounds represented by formula I, one or more compounds represented by formula II, one or more compounds represented by formula III and one or more compounds represented by formula IV, In the liquid crystal molecules of the composition, the van der Waals force therebetween is used as a motive force, such that the liquid crystal molecules generate an attractive force at an appropriate distance and positional relationships, thereby enabling the liquid crystal molecules to have excellent regular alignment characteristics, which is favorable for the liquid crystal molecules to modulate the transmission and blocking of light in the liquid crystal display device.

  • Patent number: 10703974
    Abstract: Provided is a liquid crystal compound represented by formula I, the compound having a positive dielectric anisotropy, a great elastic constant and a good solubility. Further provided is a liquid crystal composition comprising the liquid crystal compound represented by formula I, the liquid crystal composition having a good stability against light and heat, a lower viscosity, a wider refractive index that may be achieved by the adjustment of the monomer ratio, and a higher clearing point (a very wide service temperature range), and in particular, the liquid crystal composition has a higher light transmittance, thus allowing a display device to have a higher brightness or an energy saving effect.

  • Patent number: 9436646
    Abstract: Combined sockets for selectively removable cards in computing devices are disclosed. In one embodiment, a socket is provided that can accommodate both a subscriber identification module (SIM) card and a secure digital (SD) card. The cards are held in place within the socket in a back to back configuration by springs which further help insure that contacts on the cards are electrically coupled to conductive pins in the socket. While it is contemplated that the socket will be used in mobile terminals such as smart phones and tablets, the socket may be used in other computing devices that use such cards.
