  • Publication number: 20100164776
    Abstract: A source driver in a display may include a latch capable of latching input data received from a timing controller in a display, a delta-sigma digital-to-analog converter configured to convert the input data stored in the latch to an analog signal by delta-sigma modulation, and an output buffer configured to output a column drive signal by buffering the analog signal received from the delta-sigma digital-to-analog converter. Accordingly, a source driver in a display modulates input data of 10-bit or higher by delta-sigma modulation with high accuracy, and then converts the data to an analog signal. Therefore, although an area occupied by the source driver of embodiments becomes smaller than that occupied by the related art source driver with a high resolution of 10-bits or higher, a display panel can provide an image of high resolution.

  • Publication number: 20080229522
    Abstract: Customers obtain customized textile materials by selecting style, shape, size, pattern and color for an undyed textile product. Based on a selection made by the customer, the textile product is transformed by a dyeing operation performed on a single item to yield a product, such as a shirt, pants, or jacket, which has a color and pattern of his or her own choosing, in the size and style he or she desires. The process can be performed in a retail setting using a dye machine which allows the process to be viewed by the customer. Preferably, the textile material is constructed from yarns which include cationic cotton alone or in combination with natural cotton or other natural or synthetic fibers, and using anionic dyes, such as a fiber reactive dye, such that the dye is exhausted during the process and effluent from the dye machine is environmentally friendly without excess dye, salts, and alkalis.
