DISPLAY DEVICE HAVING EMBEDDED VOICE SIGNAL PROCESSING CIRCUIT

摘要

PURPOSE: A display device is provided to reduce a size and weight of the display device by embedding a voice signal processing circuit. CONSTITUTION: A display device includes thin film semiconductor elements on a substrate. The display device also includes an electric signal processing circuit for driving an output device which outputs other signals than a video signal. The electric signal processing circuit is composed of the thin film semiconductor elements. The display device also includes a voice signal processing circuit(105). The voice signal processing circuit is composed of the thin film semiconductor elements. An output signal of the audio signal processing circuit is used to drive a speaker(106).
