Abstract: A thin film circuit substrate is provided with a voice-output-section driving section, formed of a thin film layer on an insulative substrate, for driving a voice output section. An antisurge section, provided on a wiring between the voice-output-section driving section and an output terminal section thereof, includes an antisurge element.

Abstract: A D/A converter inputted with non-linear conversion digital data such as a digital signal encoded according to a ?-Law system or the like as it is to convert into an analog signal. A D/A converter is of resistor string type, in which a resistance value of each of resistors of a resistor string is not set uniform but weighted so that a non-linear relationship between an encoded input digital signal and an output analog signal is converted into a linear relationship. Consequently, a decode circuit for converting non-linear conversion digital data into linear conversion digital data is not required.

The font conversion section converts the input text code into a corresponding font, and transmits the font to a display drive section via a video signal input section, and the display drive section causes a display section to display the font.

With this structure, superior convenience is ensured for a display apparatus which serves only as an individual displaying apparatus and relies on an external device (server) for the major functions of the system.

Abstract: A thin film circuit substrate is provided with a voice-output-section driving section, formed of a thin film layer on an insulative substrate, for driving a voice output section. An antisurge section, provided on a wiring between the voice-output-section driving section and an output terminal section thereof, includes an antisurge element.
