  • Publication number: 20020090798
    Abstract: A contact structure of a touch panel having X-axis (Y-axis) potential compensating electrodes arranged along peripheries of the conductive film of a substrate; a FPC contact for another substrate constructed on an electrode arrangement defined by electrodes; the electrodes arranged along outermost peripheries of the transparent conductive film of the another substrate; and another FPC contact for the another substrate constructed on the electrode arrangement defined by the electrodes arranged on the film of the another substrate.

  • Publication number: 20020089492
    Abstract: A flat panel display with input device having enhanced assemblability and lowered failure rate is achieved by connecting a touch screen driver with a display driver. Signal distortion is reduced by simplifying wiring. Reduction of signal distortion in an input device or a flat panel display and economic benefit in its manufacture occurs by constructing a display driver and a touch screen driver on the identical printed circuit board (PCB).

  • Patent number: 6365067
    Abstract: Compositions and methods have been discovered for inhibiting corrosion of metals, particularly iron alloys, in contact with fluids, either hydrocarbons, alcohols, or aqueous fluids, employing mercaptoalcohols. The mercaptoalcohols should have at least one water solubilizing hydroxyl group. In particular, suitable mercaptoalcohols have the formula: (HS)n—R—(OH)m where R is a straight, branched, cyclic or heterocyclic alkylene, arylene, alkylarylene, arylalkylene, or hydrocarbon moiety having from 1 to 30 carbon atoms; n and m each independently averages from 1 to 3; and the heteroatom in the heterocyclic moiety substituent, if present, may be N, O, S and/or P. Preferred mercaptoalcohols include 2-mercaptoethanol, 2-mercaptopropanol, 1-mercapto-2-propanol, and 2-mercaptobutanol, in part because they are soluble in many fluids. These corrosion inhibitors show improved inhibition of both generalized and localized corrosion, specifically in high shear and high flow environments.

  • Patent number: 6297866
    Abstract: An in-plane switching mode liquid crystal display device includes first and second opposed substrates having inner surfaces in which a liquid crystal layer formed therebetween, a data bus line and a gate bus line arranged perpendicularly and/or horizontally in a matrix on the first substrate thereby defining a unit pixel region, and a pair of data electrode and common electrode applying a plane electric field in the liquid crystal layer, the electrodes being inclined with respect to the data bus line and parallel to each other.

  • Patent number: 6061106
    Abstract: A liquid crystal display device with an enhanced viewing angle characteristics includes a liquid crystal layer between first and second substrates, and a first portion having a first thickness and a second portion having a second thickness smaller than the first thickness. The first portion of the liquid crystal layer satisfies a condition .DELTA.n.multidot.d.gtoreq..lambda./2, where .DELTA.n is optical anisotropy of the liquid crystal, d is a thickness of the liquid crystal layer, and .lambda. is a wavelength of transmitted light in the liquid crystal layer.
