摘要： A small-sized, light-weight display device having an audio output circuit is provided. A display device of the present invention has a flat speaker and an audio signal processing device is constructed from thin film semiconductor elements, typically, thin film transistors, on the display device. The speaker is driven by BTL driving, thereby reducing the power supply voltage and preventing degradation of the thin film transistors. A display device with a built-in audio signal processing circuit is thus reduced in size and weight.

摘要： 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.
