    • A driving apparatus driving method of a flat panel (e.g., LCD) display device. The driving apparatus of the display device includes: a data processor that selects a (at least) two of output gray levels (output image data ) based on an input gray level (of received image data) and outputs the two output grays for each pixel to a data driver that selects two gray (reference) voltages corresponding to the output image data output from the data processor and applies the gray (reference) voltages to the pixels as data voltages. The first output gray level may be less than the second output gray level, and less than the input gray level. The first and second output gray level (and thus the first and second output grays) applied to the pixel as data voltages are optically averaged at the pixel, to have the same (average) transmittance as the original input gray level. A gray voltage generator generates and outputs a plurality of gray (reference) voltages for selection by the data driver. At least one of the plurality of gray (reference) voltages may have a value less than a liquid crystal threshold voltage.
    • 一种平板显示装置的驱动装置驱动方法。 显示装置的驱动装置包括:数据处理器,其基于所接收的图像数据的输入灰度级选择输出灰度级(输出图像数据)中的至少两个(输出图像数据),并输出每个像素的两个输出灰度 到数据驱动器,其选择与从数据处理器输出的输出图像数据相对应的两个灰度(参考)电压,并将灰度(参考)电压作为数据电压施加到像素。 第一输出灰度级可能小于第二输出灰度级,小于输入灰度级。 作为数据电压施加到像素的第一和第二输出灰度级(以及因此第一和第二输出灰度)在像素处被光学平均,以具有与原始输入灰度级相同的(平均)透射率。 灰度电压发生器产生并输出多个灰色(参考)电压供数据驱动器选择。 多个灰色(参考)电压中的至少一个可以具有小于液晶阈值电压的值。

    • Disclosed is an electrophoretic display and a method for driving the electrophoretic display. The method for driving the electrophoretic display, which includes a first electrode, a second electrode, and an electrophoretic layer including electrophoretic particles disposed in a plurality of pixels receiving the voltage for driving from the first electrode and the second electrode and provided between the first electrode and the second electrode includes applying a reset voltage to the pixels, applying a reset compensation voltage including reversed polarity to the reset voltage to the pixels, applying an image display voltage including the same or different polarity during a predetermined time between the neighboring pixels, and applying an image display compensation voltage including reversed polarity to the image display voltage to the pixels during a predetermined time. The foregoing method provides a potential distribution which is symmetrical in the boundary region between the neighboring pixels such that the display size of the real image of each of the pixels is uniform and an afterimage may be prevented, thereby improving the display performance.

    • Provided is a wiper driving apparatus for an automobile. The wiper driving apparatus includes: a housing; a driving motor; a worm wheel installed in the housing to be rotated by the driving motor, connected to a wiper arm, and having protrusions formed on a surface thereof; and a clutch member eccentric with respect to the center of the worm wheel to be rotatably installed in the housing such that power supply to the driving motor is selectively turned on or off according to the position of the rotating clutch member relative to the housing, wherein the clutch member has an engagement unit which is caught by the protrusions of the worm wheel when the worm wheel is rotated in a first direction, and is not caught by the protrusions of the worm wheel when the worm wheel is rotated in a second direction. Accordingly, the wiper driving apparatus enables the clutch member to be disposed within the radius of rotation of protrusions without deviating from its normal track although the protrusions are rotated in a reverse direction.
