  • Patent number: 8289253
    Abstract: In a method of driving a display device and a driving circuit using the driving method, when a current needed to display an image corresponding to one frame is calculated based on a data signal, a second vertical start signal delayed by a first time interval more than a first vertical start signal based on the calculated current. A first gate signal is sequentially output in response to the first vertical start signal, and a display data voltage obtained from the data signal is output during a high period of the first gate signal. A second gate signal is sequentially output in response to the second vertical start signal, and a black data voltage is output during a high period of a second gate signal. Thus, the current applied to a display part is controlled, thereby reducing power consumption and improving moving image.

  • Patent number: 8279149
    Abstract: 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.
