  • Publication number: 20080218232
    Abstract: A display device includes a timing controller and a display unit. The timing controller receives an external clock signal, reads signal generation information, and generates and outputs an internal clock signal based on the read signal generation information. The display unit receives the internal clock signal and displays an image. When the internal clock signal is abnormal, the timing controller rereads the signal generation information and generates and outputs the internal clock signal based on the reread signal generation information.

  • Patent number: 7334200
    Abstract: A low-error fixed-width multiplier receives a W-bit input and produces a W-bit product. In an embodiment, a multiplier (Y) is encoded using modified Booth coding. The encoded multiplier (Y) and a multiplicand (X) are processed together to generate partial products. The partial products are accumulated to generate a product (P). To compensate for the quantization error, Booth encoder outputs are used for the generation of error compensation bias. The truncated bits are divided into two groups, a major least significant bit group and a minor least significant bit group, depending upon their effects on the quantization error. Different error compensation methods are applied to each group.

  • Publication number: 20060247125
    Abstract: The present invention provides for titanium oxide-based photocatalysts having a general formula of TiO2-X-?CXN? and self-cleaning materials that are prepared by substituting O of pure TiO2 with C and N. A preparation method comprising a process for forming thin films of TiO2-X-?CXN? by using gases such as Ar, N2, CO2, CO and O are used for reactive sputtering, and a process of heat treating at around 500° C., thereby crystallizing, is provided. The titanium oxide-based photocatalysts having a general formula of TiO2-X-?CXN? and self-cleaning materials according to the present invention have a smaller optical bandgap compared to pure titanium oxides, and therefore, the photocatalysts can be activated under the visible light range. In addition, they comprise only pure anatase crystallization phase, and since the crystallized particles are small in size, the efficiency and self-cleaning effect of the photocatalysts are very high.
