摘要： A method and apparatus for driving a display device, as well as a display device incorporating such method and apparatus, are presented. The method includes determining a first difference Δ1, wherein Δ1 is a difference between gray signals of two consecutive frames, comparing Δ1 to a predetermined value to obtain a comparison result, and using the comparison result to determine a modified current gray signal. The modified current gray signal is applied to a current frame to improve image quality. In another aspect, the invention includes a method of driving a display device by determining the gray signal levels for a first frame, a second frame that follows the first frame, and a third frame. A modified current gray signal is determined based on the relative magnitudes of the three gray signal levels, and applied to the current frame.

摘要： Ultrahigh resolution patterning, preferably carried out by DIP PEN™ nanolithographic printing, can be used to construct peptide and protein nanoarrays with nanometer-level dimensions. The peptide and protein nanoarrays, for example, exhibit almost no detectable nonspecific binding of proteins to their passivated portions. This work demonstrates how DIP PEN™ nanolithographic printing can be used in a method to generate high density protein and peptide patterns, which exhibit bioactivity and virtually no non-specific adsorption. It also shows that one can use AFM-based screening procedures to study the reactivity of the features that comprise such nanoarrays. The method encompasses a wide range of protein and peptide structures including, for example, enzymes and antibodies. Features at or below 300 nm can be achieved. In a preferred embodiment, parallel printing with multipen systems are used.

摘要： An apparatus of driving a liquid crystal display (LCD) includes a gray voltage generator generating a range of gray voltages that correspond to different LC light transmittance levels. These gray voltages, along with image data, are fed into a data driver. The data driver converts the gray voltages to a data voltage that properly generates the image indicated by the image data. The gray voltage values are chosen from a wider range of values than the pixel voltages, and this conversion may include determining a conversion factor based on the relative range sizes. This conversion may also include calculating the voltage difference between the previous data and the current data and adjusting the data voltage according to the magnitude of this difference. Generally, the larger the voltage difference, the larger is the data voltage magnitude that is needed to bring the pixel voltage to the target voltage within limited time.

摘要： A digital driving circuit for a liquid crystal display which sequentially receives and displays n-bit digital video information from a data bus on a bit basis. The digital driving circuit comprises a first data latch for sequentially storing the digital video information from the data bus on a bit basis, a shift register for synchronizing a latching operation of the first data latch with bit positions of the digital video information from the data bus, a second data latch for storing the digital video information stored in the first data latch temporarily before digital/analog conversion, and a digital/analog converter for sequentially converting the digital video information stored in the second data latch into analog signals on a bit basis. The digital driving circuit is able to sequentially process bit information of digital video information to reduce the number of data bus lines for loading the bit information thereon and the number of data catches arranged vertically to a column direction. Therefore, the driving circuit can be significantly reduced in its occupying width, thereby making it possible to make the display higher in density.
