Liquid crystal display and method of driving the same

A liquid crystal display (“LCD”) includes an LCD panel, a data driving unit, and a selection unit. A configuration of the selection unit, which includes a plurality of switching devices driven by a selection control signal to connect a plurality of data lines to each channel of the data driving unit, is adjusted according to the selection control signal, so that charging voltages of the same color pixels of the LCD panel are made the same, whereby no stripe defect appears. In addition, the configuration of the selection unit is adjusted according to the selection control signal and the polarity change of the data signal supplied from the data driving unit, so that color aggregation caused by supplying the same polarity voltage to adjacent color pixels of the LCD panel can be minimized.

Authentication with built-in encryption by using moire parallax effects between fixed correlated s-random layers

This invention discloses new methods and security devices for authenticating documents and valuable products which may be applied to any support, including transparent synthetic materials and traditional opaque materials such as paper. The invention relates to parallax moire shapes which occur in a compound layer consisting of the superposition of specially designed and possibly geometrically transformed s-random base layer and s-random revealing layer with a small gap between them. The base and revealing layers are formed respectively by base layer element shapes and revealing layer sampling elements positioned at s-random locations, where the base layer locations and the revealing layer locations are strongly correlated. When tilting the compound layer or changing the viewing angle, a parallax moire intensity profile of a chosen shape is seen moving in the superposition, thereby allowing the authentication of the document. A major advantage of the present invention is in its intrinsically incorporated encryption system due to the arbitrary choice of the s-random number sequences used for defining the positions of the specially designed base layer element shapes and revealing layer sampling elements that are used in this invention.

Pressure-sensitive adhesive optical film and image display

A pressure-sensitive adhesive optical film of the present invention comprises: an optical film comprising a transparent base film and a discotic liquid crystal layer on one side of the transparent base film; and a pressure-sensitive adhesive layer that is provided on the discotic liquid crystal layer, wherein the pressure-sensitive adhesive layer is made from a pressure-sensitive adhesive containing an acrylic polymer comprising an alkyl(meth)acrylate (a1) and a ring structure-containing (meth)acrylate (a2) as monomer units and having a weight average molecular weight of 1,000,000 to 3,000,000, and a crosslinking agent. The pressure-sensitive adhesive optical film has durability and can be prevented from causing display unevenness in a peripheral portion of a display screen.

Seal for an adjustable threshold assembly

An adjustable threshold assembly for disposition below a door includes a sill, a rail spaced from the sill and configured to be vertically adjustable relative to the sill, and a seal disposed between the rail and the sill. The seal includes a first portion and a second portion each engaging one of the sill and the rail, respectively, and a flexible intermediate portion connecting the first and second portions. The seal includes a bulb extending from the first portion and contacting the second portion. The bulb includes a first end and a second end each extending from the first portion. The bulb encloses a cavity between the first and second ends such that the bulb resiliently collapses between the rail and the sill as the rail is vertically adjusted relative to the sill to maintain contact between the bulb and the second portion.
