  • Publication number: 20080252831
    Abstract: A color filter substrate for a liquid crystal display and a method of fabricating the same are provided. The color filter substrate for a liquid crystal display includes: light shielding parts formed on a substrate at predetermined intervals to prevent light leakage; color filter Layers disposed between the light shielding parts and including color filter patterns of red (R), green (G) and blue (B) for implementing a color image; and a transparent conductive layer formed on a rear surface of the substrate, on which the color filter layers are formed, and formed in a porous structure having a plurality of holes spaced at predetermined intervals. Therefore, it is possible to shield an electrostatic field due to external static electricity and improve image display quality, thereby increasing high brightness characteristics and readability.

  • Publication number: 20080129737
    Abstract: A method for producing cartoon animation using character animation and mesh deformation is provided. The system includes a motion analysis module, a mesh deformation module, a motion deformation module, and a skinning module. The motion analysis module receives existing motion data having information about non-deformed motions of a character, and extracts parameters from the existing motion data by analyzing an animation value that a character's each joint has. The mesh deformation module receives existing mesh data having information about an external appearance of a character and existing skinning data having information for cohering the parameters or bones with mesh, and generates deformed mesh data. The motion deformation module receives the existing motion data and deforms motion using the parameters. The skinning module receives the deformed mesh data, the deformed motion data, and the existing skinning data and generates character animation data having cartoon like motion.

  • Publication number: 20080100782
    Abstract: A transflective liquid crystal display device has improved light efficiency. A method of fabricating a transflective liquid crystal display device including a thin film transistor substrate having a transmissive region and a reflective region, includes forming a retardation layer on a lower surface of the thin film transistor substrate, aligning a mask having a reflective region pattern on the lower surface of the thin film transistor substrate, and forming a light efficiency enhancer by selectively removing the retardation layer by irradiating a laser onto the lower surface of the thin film transistor substrate through the mask.

  • Publication number: 20070024781
    Abstract: A display panel assembly includes a display panel, a first polarizing plate disposed over the display panel, a second polarizing plate disposed under the display panel, and a polarization compensation film disposed over the first polarizing plate. The polarization compensation film includes a polarization prism film and a phase difference film. The polarization prism film divides a natural light wave into an ordinary wave with a first polarization state, and an extraordinary wave with a second polarization state. The phase difference film changes the second polarization state of the extraordinary wave into the first polarization state.

  • Patent number: 7062271
    Abstract: A system and method for managing communications in a mobile terminal selects a serving cell of a first PLMN for the mobile terminal, monitors signal strengths of neighboring cells in at least a second PLMN, classifies the neighboring cells as signal-receivable cells and signal non-receivable cells based on the monitored signal strengths, determines whether cell reselection is required, searches for state information corresponding only to the signal-receivable neighboring cells, and selecting one of the same receiving cell or one of the signal-receivable neighboring cells as a new serving cell. By searching only a pre-stored list of signal-receivable cells instead of all neighboring cells around the mobile terminal, the time for reselecting a cell during mobile terminal operation is significantly reduced.

  • Publication number: 20030224790
    Abstract: A system and method for cell reselection in a radio communication network is provided. The system comprises a mobile terminal transmitting a receive signal strength list after measuring signal strengths of at least a neighbor cell; and a host system selecting a cell suitable for the mobile terminal based on a suitable cell list and the receive signal strength list and transmitting the cell reselection information to the mobile terminal. The suitable cell list comprises information representing whether or not the neighbor cell is suitable for selection by the mobile terminal.
