  • Patent number: 11914825
    Abstract: A flexible display device including a display panel providing a base surface and a touch screen disposed on the base surface. The display panel may include a plurality of light emitting areas and a non-light emitting area disposed adjacent to the light emitting areas. A plurality of touch electrodes and a plurality of insulating layers of the touch screen may have a mesh shape through which openings corresponding to the plurality of light emitting areas are defined. Accordingly, a flexibility of the flexible display device is improved, and the touch electrode is prevented from being cracked.

  • Patent number: 10100161
    Abstract: The present disclosure relates to a polyamide-based polymer composition with superior fluidity and a polyamide-based composite material with superior mechanical strength prepared therefrom. More specifically, it relates to a polyamide-based polymer composition containing 0.1-5 parts by weight of dicyclohexylmethane bisdecanoamide, which is a cyclic compound, as a fluidity control agent based on 100 parts by weight of a mixture consisting of 20-90 wt % of a polyamide-based resin and 10-80 wt % of a reinforcing fiber, a polyamide-based composite material prepared using the same, and a method for preparing the same. The polymer composition according to the present disclosure, wherein dicyclohexylmethane bisdecanoamide is used as a fluidity control agent, provides an effect of reducing friction between a molten resin and a processing machine and greatly reducing torque by effectively dispersing a reinforcing fiber in a polyamide-based resin.
