摘要： In one embodiment of the present invention, an active-matrix type display unit, and a drive method thereof are disclosed. Gate-bus lines are provided at both top and bottom sides of each row. Two sub-pixels are formed at a region surrounded by two adjacent source-bus lines and two adjacent gate-bus lines. At the odd-numbered rows, for the left-side sub-pixel of those two sub-pixels, a scanning signal is supplied from the top-side gate-bus line, while a video signal is supplied from the left-side source-bus line. For the right-side sub-pixel, on the contrary, a scanning signal is supplied from the bottom-side gate-bus line, while a video signal is supplied from the right-side source-bus line. At the even-numbered rows, the gate-bus line from which a scanning signal is supplied is reversed to the case of the odd-numbered rows. The gate-bus lines are sequentially selected one by one, and all the video signal polarities are made the same during each horizontal scanning period.

摘要： A gradation conversion unit 23 performs, on an input image, gradation conversion in which a predetermined gain is applied to a gradation smaller than a boundary gradation CVth and a characteristic becomes a spline curve for a gradation larger than the boundary gradation. To determine a characteristic of the gradation conversion unit 23, an image analysis unit 22 obtains the boundary gradation CVth and a maximum gradation CVmax based on the input image, and determines a linear gain shift coefficient LGs so that the brightness decreasing rate of the maximum gradation CVmax when brightness control of a backlight 30 is performed becomes a limit value or less. In such a manner, power consumption of the backlight is reduced while suppressing deterioration in picture quality.
