摘要： An object of the present invention is to provide (i) a display device which, during a display of a moving image and a still image, reduces electric power consumption without causing a deterioration in display quality, and (ii) a method for displaying the display device. In an intermittent drive mode in which driving and a pause of the driving are repeated, an image identification section (6) identifies an input image (image data (DA)) as a still image or a moving image. In a case where the input image is identified as the moving image, a drive/pause control section (7) generates a drive/pause control signal (DSC) in accordance with a period ratio which is in accordance with the moving image. A timing control section (8) generates a driver control signal so that intermittent driving is carried out. Then, a source driver (3) and a gate driver (4) drives a display section (2) so that the drive period and the pause period are repeated in accordance with a predetermined period ratio, so that the input image (DA) is displayed. The drive/pause control section (7) sets a time ratio between the drive period and the pause period so that the time ratio is variable for each of the moving image and the still image.

摘要： In one embodiment of the present invention, LUTs (T3) through (T5) are stored in a table memory. When an overshoot calculation section switches over from the LUT (T4), which is being used, to the LUT (T5), the overshoot calculation section obtains the LUT (T5) not out of an external memory but out of the table memory. At this time, in order that the overshoot calculation section can switch over quickly from the LUT (T5) to an LUT (T6) at the next time, a table managing section deletes, from the internal memory, the LUT (T3) to which the LUT (T5) does not switch over directly, meanwhile the table managing section obtains the LUT from the external memory so as to store the LUT (T6) in the table memory. With the arrangement, it becomes possible for a drive circuit to (i) operate at the same processing speed as a drive circuit in which all tables are stored in the internal memory, and simultaneously, (ii) reduce the amount of memory.

摘要： In one embodiment of the present application, a memory stores a lookup table storing, in accordance with a combination of a value of a video signal of a current frame and a value of a video signal of a previous frame, each of correction values, the correction values in each of which a temporal change of a video signal is enhanced. A correcting circuit carries out, with respect to a correction value selected from the lookup table, a predetermined correcting operation in accordance with a polarity of a voltage to be applied to each of data signal lines S1 through Sm, with the use of a correction coefficient which is set based on properties of liquid crystal. Thus found is a corrected video signal in accordance with a positive or negative polarity. This makes it possible to find, with less memory capacity, an optimum corrected video signal in accordance with a polarity of a voltage to be applied to a data signal line.
