  • Publication number: 20020154085
    Abstract: A method of driving a liquid crystal display panel including the steps of sequentially applying first-polarity gate pulses to odd-numbered gate lines of the liquid crystal display panel such that a portion of one of first-polarity gate pulse applied to one odd-numbered gate line is superposed with at least another first-polarity gate pulse applied to a second odd-number gate line; sequentially applying second-polarity gate pulses to even-numbered gate lines of the liquid crystal display panel such that a portion of one second-polarity gate pulse applied to one even-numbered gate line is superposed with another second-polarity gate pulse applied to a second even-numbered gate line; and applying data pulses to the data lines in synchronization with the gate pulses. The liquid crystal display panel has pixels arranged at intersections between gate lines and data lines.

  • Publication number: 20020140876
    Abstract: A liquid crystal display and a fabricating method thereof that are capable of realizing a high aperture ratio as well as implementing a high-density storage capacitor. The liquid crystal display is provided with a data line supplied with a data signal, a gate line supplied with a scanning signal, a pixel electrode for driving a liquid crystal cell, and a thin film transistor for applying the data signal to the pixel electrode in response to the scanning signal. In the liquid crystal display, a gate insulating film covers the gate line. A storage electrode is formed at the interior of the gate insulating film to overlap with the gate line. Accordingly, the storage electrode is formed within the gate insulating film to reduce a thickness between the conductive materials, thereby increasing a capacitance value. As a result, the storage capacitor area is set to a small size to thereby improve an aperture ratio.

  • Patent number: 6414735
    Abstract: A reflectance-type liquid crystal display device includes a first light scattering unit on a first substrate, a reflecting layer having a second light scattering unit on a second substrate, and a liquid crystal layer between the two substrates. One of the two light scattering units defines a regular-directional scattering unit which can easily control the reflectance characteristics, and the other light scatterin unit defines a random-directional scattering unit which prevents the light interference caused by the regular-directional scattering unit.

  • Publication number: 20020071086
    Abstract: An LCD panel of high resolution (with decreased pixel pitch) and a method for manufacturing the same. In the LCD panel, the even numbered data lines are formed only up to the cell region of a substrate and then extended up to the pad region using conductive patterns. With the use of refracted conductive patterns, the even numbered data pads could be extended from the even numbered data lines and arranged parallel to the odd-numbered data pads along the longitudinal direction of odd-numbered data lines, thereby decreasing the pitch. Instead of using the conductive patterns, the even numbered data lines may be made longer than the odd numbered data lines in the pad region and may be refracted appropriately to arrange the even numbered data pads in parallel to the odd numbered data pads along the longitudinal direction of the odd numbered data lines.

  • Patent number: 6384885
    Abstract: A reflective-type liquid crystal display device is disclosed which comprises first and second substrates; a metal layer having a convex-concave surface over the insulating layer; a &lgr;/4 phase retardation optical film over the second substrate. The convex portion of the metal has a long width in a first direction perpendicular to the main viewing angle direction of the user. Polarization direction of the polarizer is at 90° with respect to the first direction, and slow axis of the optical film is at 45° with respect to the polarization direction. This reflective-type LCD has a high reflective luminance in the main viewing angle direction. Further, because TE(transverse electric) polarized light is incident on the metal transverse electric, the reflective luminance is much more improved.
