  • Patent number: 10446091
    Abstract: A display control method of an electronic device is provided. The display control method includes sensing, by the electronic device, a chromaticity and an illuminance of an incident light, calculating an optimal white of a display based on the chromaticity of the incident light, and correcting the calculated optimal white by using the illuminance of the incident light.

  • Patent number: 9827799
    Abstract: Disclosed herein is a transfer printing technology. A transfer printing substrate includes a plurality of pillar structures and a sacrificial layer applied thereon. In situ alignment of a transfer layer is performed by the pillar structures and a structural confinement by a concave structure formed on a bottom surface of the transfer layer corresponding to the pillar structures, or a chemical bond of the pillar structure and the transfer layer. In the in situ alignment by the structural confinement, the remaining sacrificial layer after being removed may serve as an adhesive component. The transfer process is performed by a separation of the bond by the sacrificial layer, a cutting of the pillar structures in the chemic bonding state of the pillar structures and the transfer layer, or a separation of the bond between the pillar structures and the handling substrate.

  • Patent number: 9656502
    Abstract: The present disclosure provides a method for fabricating a substrate for transfer printing using a concave-convex structure and a substrate for transfer printing fabricated thereby. The method includes preparing a handling substrate having a concave-convex structure formed thereon; forming a sacrificial layer along the concave-convex structure on the handling substrate; coating a polymer on the handling substrate having the sacrificial layer formed thereon to form a polymer substrate having bumps filling a concave portion of the concave-convex structure; and removing the sacrificial layer from the handling substrate. The substrate for transfer printing includes a handling substrate having a concave-convex structure formed thereon; and a polymer substrate placed on the concave-convex structure and having bumps filling a concave portion of the concave-convex structure of the handling substrate.

  • Patent number: 9368346
    Abstract: A method of preparing zinc oxide nanostructures using a liquid masking layer is disclosed. The method includes preparing a substrate having a zinc oxide seed layer formed thereon; loading the substrate in a reactor in which a lower liquid masking layer, a precursor liquid layer for hydrothermal growth, and an upper liquid masking layer are disposed in order; and forming zinc oxide nanostructures in a pattern on the substrate through hydrothermal growth by heating the precursor liquid layer for hydrothermal growth.
