Abstract: An image display method includes generating luminance data, correcting the luminance data, generating gradation setting data, and controlling a backlight to operate based on the luminance setting data and a liquid crystal panel to operate based on the gradation setting data. The luminance data indicates a luminance value for each light-emitting region of the backlight and is generated based on a maximum gradation value among gradation values of image pixels of an input image that correspond to the light-emitting region. The luminance data is corrected such that, with respect to each light-emitting region, the luminance value is within a predetermined range below a maximum value among the luminance values of neighboring light-emitting regions, and luminance setting data is generated therefrom. The gradation setting data sets a gradation value of each pixel of the liquid crystal panel, and generated based on the input image and the luminance setting data.

Accordingly, variation in luminance of each pixel is suppressed.

Abstract: The occurrence of flicker is effectively suppressed particularly in a liquid crystal display device that performs low-frequency driving. Provided are a gradation-to-voltage value conversion table for converting a gradation to a voltage value, a correction value map for storing a correction value, and a voltage value-to-gradation conversion table for converting a voltage value to a gradation. A gradation of an input image signal is converted to a first voltage value, using the gradation-to-voltage value conversion table. The correction value specified in accordance with a location of a pixel to be processed is added to or subtracted from the first voltage value so that a second voltage value is obtained. The second voltage value is converted to an output gradation, using the voltage value-to-gradation conversion table. A driving video signal is applied to a source bus line, based on the output gradation.

Abstract: The present invention provides a liquid crystal display device capable of suppressing a decrease in display quality when pause drive is performed in an alternating-voltage drive mode, as well as a method for driving the same. In a first drive frame, overshoot drive is performed using correction values provided by an LUT to apply overshoot voltages whose absolute values are higher than absolute values of signal voltages to data signal lines. Subsequently, in a second drive frame, normal drive is performed to write signal voltages of the same polarity as the overshoot drive voltages to the data signal lines. Thereafter, a pause period in which an image written by normal drive is displayed continues until the start of a drive period in the next pause drive period. As a result, a decrease in luminance immediately after the signal voltages are written during the second drive frame is suppressed significantly, so that the viewer barely recognizes flicker.

Abstract: There is provided an image display device, in which a pixel includes sub-pixels of four or more colors that include a color in addition to the three primary colors, and which can display a high-quality image in which false colors or artifacts are suppressed. The image display device includes a pixel area in which a plurality of pixels P are arranged in a matrix shape, and each of the pixels P includes m (m is an integer which is equal to or greater than 4) sub-pixels SP. When it is assumed that the colors of the m sub-pixels SP included in one pixel are C1, C2, . . . , and Cm, the m sub-pixels SP which are sequentially arrayed from an arbitrary position include all of the colors of C1, C2, . . . , and Cm in both the vertical direction and the horizontal direction in the pixel area.

Abstract: Grayscale values for previous and current frames are different, and therefore, an overshoot voltage, which has a higher absolute value than a signal voltage, are applied to a data signal line. Next, in a second drive frame, normal drive is performed, so that a signal voltage of the same polarity as the overshoot voltage is written to the data signal line. Moreover, in a first drive frame of a third pause drive period, the grayscale values for the previous and current frames are equal, and also greater than or equal to a boundary value, and therefore, undershoot drive is performed. An undershoot voltage, which has a lower absolute value than a signal voltage, is applied to the data signal line. Next, in a second drive frame, normal drive is performed, so that a signal voltage of the same polarity as the undershoot voltage is written to the data signal line.

Abstract: An image determination part configured to determine whether or not an image based on an input image signal is an image analogous to a polarity reversal pattern in a reversal driving scheme employed by default and to output a determination result, and a reversal pattern decision part configured to decide a reversal driving scheme based on the determination result are provided as constituent elements anterior to a liquid crystal drive unit. With regard to each unit area where the determination by the image determination part is made, the reversal pattern decision part decides the reversal driving scheme in the unit area, as a reversal driving scheme different from the reversal driving scheme employed by default, when the determination result indicates that the image based on the input image signal is the image analogous to the polarity reversal pattern in the reversal driving scheme employed by default.
