  • Patent number: 8780305
    Abstract: A liquid crystal display includes a first substrate with pixel electrodes, and a second substrate with a common electrode facing the first substrate. The common electrode has depression patterns corresponding to the pixel electrodes. The side wall of each depression pattern is at an angle of 30-120 degrees with respect to the first substrate. The depression patterns of the common electrode are formed through making depression patterns at color filters. In this structure, the liquid crystal display bears wide viewing angle and good picture quality.

  • Patent number: 8719343
    Abstract: A system and method for managing membership in real-time using a community page that enables communication between a member and a provider is disclosed herein. The membership management system may include an information transferring unit to transfer access information, used to encourage an access to a community page associated with or created by the provider, to at least one member, and a business information providing unit to provide business information of the provider to members who access the community page, via the community page. The membership management system may transmit information associated with an access to a community page to a member, thereby encouraging the member to access the community page. Therefore, the community page may provide real-time communication between the provider and the member.

  • Patent number: 6717637
    Abstract: Color filters of an LCD are formed so as to have grooves. A common electrode is formed thereon to have a rugged non-smooth profile due to the grooves. A skewed electric field is formed due to the rugged non-smooth profiled common electrodes. Two domains in which alignment directions of liquid crystal molecules are opposite to each other are separated by the grooves as a boundary, and hence, the viewing angle of the LCD is broadened. A black matrix may be formed to overlap the grooves to reduce light leakage induced due to the groove. To prevent common electrodes from disconnecting around the groove, the common electrode layer is preferably thinly deposited two times.
