  • Patent number: 6919872
    Abstract: A driver for driving an STN LCD is disclosed. A preferred embodiment comprises a 3-line output display data for storing display data, an XOR block for finding mismatches between each 3-line output set of the stored display and orthogonal function signals, a decoder block for calculating mismatch numbers, a level shifter block for shifting the data level of the mismatch numbers to another level, and a voltage selector block for selecting a voltage level from 2 levels of voltage. Because data latches and output latches are not necessary, the driver of the present invention achieves significant reduction in the circuit components and chip size without compromising the display quality.

  • Publication number: 20050024575
    Abstract: A liquid crystal display device, and a fabricating method thereof, with improved bonding of an upper plate to a lower plate. The lower plate includes an organic protective film over an inorganic gate insulating layer that is on a substrate. Channels through the organic protective film expose either metal patterns or the gate insulating layer. A seal coated with a sealant is then placed over the organic protective film and channels. The sealant passes through the channels to the metal patterns or to the gate insulating layer. Bonding of the seal to the lower plate is improved by the sealant that contacts the metal patterns and/or the gate insulating layer. During LCD fabrication, the metal patterns act as etch stops when etching the channels. Alternatively, an etch stop semiconductor layer is placed on the gate insulating film. The etch stops prevent the etching process from exposing the lower substrate.

  • Publication number: 20040050795
    Abstract: To more effectively remove contaminants from fluid streams, several types of metal precursors can be incorporated onto highly ordered mesoporous molecular sieves, such as SBA-15, without producing of clogging effects within pore structures. Lanthanum and aluminum are the most favorable incorporated metals in terms of their adsorption capacities and fluid velocities. The lanthanum impregnated SBA-15 also has a very strong selectivity for arsenic because its adsorption capacities do not deteriorate even if several other anionic species, such as sulfate and nitrate, are found in high concentrations in the fluid along with any arsenic. As a result, these hybrid materials have many advantages for use in POE/POU applications, among others, due to its rapid and high adsorption capacity, and its high selectivity of arsenic for removal from the fluid stream.

  • Publication number: 20030058203
    Abstract: A single-chip column driver for organic light emitting diode (OLED) display is disclosed. Instead of using two column drivers for dual scan, the present invention uses one column driver driving both the upper and the lower OLED panels. The column driver has a two set of output circuitry: one for driving the upper panel and the other for driving the lower panel. The single chip solution of the present invention eliminates the problem of display uniformity without increasing the part count. The invention also enables independent control of RGB without further increasing the part count.

  • Patent number: 6104065
    Abstract: A semiconductor device and a method for fabricating the same, wherein a thick side wall oxide film or polysilicon film is formed on the edge portion of the second silicon substrate. At the side wall of the oxide film or polysilicon film, the thickness of an active semiconductor substrate at its edge portion increases, thereby obtaining an increased threshold voltage at the edge portion. That is, the formation of the side wall oxide film is carried out to prevent a gate oxide film of the semiconductor device from being directly formed on each side wall of the active silicon substrate. As a result, it is possible to prevent a degradation in electrical characteristic due to a degradation in threshold voltage caused by a reduced thickness of the active semiconductor substrate at its edge portion.
