摘要： A liquid crystal display panel 51 of N rows.times.M columns is driven by a segment driver 52 with two different voltages VS1, VS2, and by a common driver 53 with three voltages VC1, VC2, VC3. An output voltage waveform of the segment driver 52 is modulated for gradation display. The two different voltages VS1, VS2 are selected to be low voltages so as not to require high withstand voltage process in the segment driver 52, which makes it easier to integrated to a large scale in the case of realizing the segment driver 52 as a semiconductor integrated circuit.

摘要： In a temperature detecting circuit of the present invention, a bias voltage Vin with relatively steep temperature characteristics is supplied to an inverting input terminal of an inverting amplifier via a resistance R1, a resistance R2 is disposed between the inverting input terminal and an output terminal of the inverting amplifier, and an output of the inverting amplifier is supplied to a non-inverting input terminal of a non-inverting amplifier, and an inverting input terminal of the non-inverting amplifier is connected with a source of a reference potential via a resistance R3 and further connected with an output terminal via a resistance R4. Desired temperature characteristics can be obtained by properly setting resistivities of the resistances R1 and R2, while a desired output voltage value can be obtained for the temperature characteristics given by the inverting amplifier by properly setting resistivities of the resistances R3 and R4. This allows temperature detection with relative accuracy between the two bias voltage sources, by the inverting amplifier outputting a voltage according to a difference between two bias voltages Vin and Vbias with different temperature characteristics, enabling the temperature detecting circuit to be adapted to various temperature characteristics and output dynamic range.
