摘要： In an active-matrix LCD device, a coupling signal in accordance with a sum of outputs of data signal lines is detected by a detection-use bus line crossing each of the data signal lines. The coupling signal is superimposed via a coupling capacitor on an input signal that serves as a reference, and is inverted and amplified by a inverting-amplifying section, then it is outputted as a common electrode signal. With this, a waveform that corresponds to a sum of the outputs is coupled with the common electrode signal. As a result, the common electrode signal is caused to have an influence that corresponds to a fluctuation of a potential of the common electrode due to outputs of the data signal lines and that is reverse in phase, thereby enabling to prevent horizontal shadow due to the outputs of the data signal lines. Thus, it is possible to realize an active-matrix-type LCD device in which horizontal shadow can be prevented with low power consumption.

摘要： In one embodiment of the present invention, a display controller includes a stable pixel writing period in one horizontal period in a display device, the stable pixel writing period being a period during which a voltage outputted from a gate driver is at a high level. The display controller also includes a first stable pixel writing period determination circuit which determines, by using a reference signal independent from the frame rate in the display device, the stable pixel writing period during which the voltage is at the high level. Thus, the display controller can be provided in which, regardless of whether and how the frame rate is changed, the stable pixel writing period can be of a target length.

摘要： In one embodiment of the present invention, when a still image is displayed, applied voltages respectively corresponding to a total of n (n being an integer of not less than 4) types of gradation 0 to (n−1) are outputted to pixels. When a moving image is displayed, an applied voltage corresponding to a predetermined gradation m (1≦m≦(n−2)) is applied to the pixels instead of applied voltages respectively corresponding to gradations of less than the predetermined gradation m. Overdrive driving is performed with respect to a total of n types of gradation.
