摘要： A simultaneous precharge type display device source driver includes supply control circuits each of which is provided on each of source bus lines. Each of the supply control circuits receives (a) a precharge control signal for precharging each of the source bus line and (b) a sampling control signal for writing data, which should be written on pixels, onto the source bus line. The one of two switches turns ON in response to the precharge control signal and the sampling control signal. The other of the switches turns ON in response to the sampling control signal. In the sampling operation, both the switches are turned ON so as to quicken the writing operation. In the precharge operation, the other switch does not operate, so that it is possible to reduce the power consumption.

摘要： A display driving circuit which carries out CC driving is configured such that a polarity of a data signal to be supplied to a source line is reversed every two horizontal scanning periods and a signal electric potential written from the source line to a pixel electrode changes in a different direction every two adjacent rows. In at least one example embodiment, this allows, in a display device which carries out CC driving, enhancement of a display quality by removing lateral stripes that are produced in a display video while n-line reversal driving is being carried out.

摘要： In one embodiment of the present invention, on each source bus line, an electric charge escaping transistor is provided having the same polarity as a pixel transistor and having a gate to which a turn-off voltage signal of the pixel transistor is supplied. When an active matrix liquid crystal display device is powered off, the turn-off voltage signal is made to reach the GND level before a turn-on voltage signal of the pixel transistor reaches the GND level, so that the pixel transistor and the electric charge escaping transistor are made half-open. This lets electric charges accumulated in the pixel escape to a common electrode TCOM.
