Abstract: In a liquid crystal display device that performs horizontal divisional-drive operation, writing of a pixel voltage to pixels in a head row in vertical scanning of each display region becomes insufficient, and a dark line is displayed when the head row is located at the screen center, deteriorating the image quality. For example, a scanning line drive circuit to drive gate lines of a lower display region sequentially outputs a scanning pulse (Pk) for selecting a (n+k)th row of an image. A video line drive circuit to drive source lines of the lower display region outputs a pixel voltage corresponding to data (Dn+k) during a period of the scanning pulse (Pk). An application start timing of the pixel voltage with respect to application of the scanning pulse (Pk) is set earlier in a (n+1)th row, a head row, during an effective scanning period (TEFF) than in the subsequent rows.

Abstract: A liquid crystal display (LCD) device and a method for driving LCD. Such a device may have a plurality of LCD pixels in a matrix, a driver that inputs a drive signal to each pixel selectively and a controller that controls a level and a polarity of the drive signal, and a memory storing corrected charge voltage values. Each pixel is provided with the drive signal based on the corrected charge voltage values for the corresponding pixel during the entirety of a horizontal period, and the corrected charge voltage value has a predetermined value corresponding to a charge for an intended gray scale level of the pixel at the end of the horizontal period without an over shooting of the driving voltage. When the target gray scale of the pixels is at the brightest level, a predetermined negative corrected charge is applied to the pixel to avoid an after image.
