Abstract: The liquid crystal display device has a liquid crystal panel in which liquid crystal cells are disposed in intersection areas of scanning lines and data lines, respectively. A picture signal and a synchronous signal are supplied via external terminals, respectively. A timing controller generates a driving timing of the scanning lines and a driving timing of the data lines in response to the synchronous signal. Further, the timing controller varies at least one of the driving timing of the scanning lines and the driving timing of the data lines according to a cycle of the synchronous signal in order to keep a writing time of the picture signal supplied to the liquid crystal cells constant. Therefore, it is possible to keep the writing time constant even when the cycle of the synchronous signal varies, which can prevent the deterioration in display quality.

Abstract: In a pixel circuit formed by using a MOS process, a constant current is applied from a second transistor (T2) as a constant current source to an organic EL device coupled to a third transistor (T3) so that the organic EL device emits light, during the period when the third transistor (T3) is in the conductive state. The third transistor (T3) is switched on and off based on its gate voltage dependent upon a signal value written to a capacitor (Cs) and a ramp signal voltage (Vcs). Thus, the organic EL device emits light during the period dependent upon the signal value. That is, displaying operation is implemented with gray-scale being controlled according to a video signal value.
