ABSTRACT:
When a digital video signal inputted to a latch circuit is Hi electric potential, undesirably a current flows continuously for one horizontal period at maximum, and this causes a great increase in power consumption of a semiconductor device. Therefore an object of the present invention is to provide a display device in which power consumption can be reduced by minimizing occurrence of the current path during the circuit operation, as well as a driving method. The present invention provides a semiconductor device in which two outputs, a non-inverted output and an inverted output, are obtained when a digital video signal is inputted and therefore occurrence of the current path can be minimized in a downstream buffer driven by these signals. Furthermore, a semiconductor device with reduced power consumption is provided by using the structure described above.
