    • A liquid crystal driving integrated circuit capable of adjusting display contrast and requiring no externally attached components. Transmission gates TG0-TG10 are provided at respective connection points of twelve resistor elements connected in series between a power supply and the ground. One of the voltages V0-V10 derived from the transmission gates TG0-TG10 in accordance with control signals CA0-CA10 is applied to an operational amplifier 8, and used as a reference voltage VLCD0. The control signals CA0-CA10 are obtained by decoding control data D0-D3 supplied from an external source by a decoder 19. Therefore, the reference voltage VLCD0 can be set in a plurality of stages simply by changing control data D0-D3 to a user specified value. As the twelve resistor elements connected in series are formed on the same semiconductor substrate, display contrast can be adjusted without requiring any external components attached to a liquid crystal driving integrated circuit 1.

    • A liquid crystal driving integrated circuit capable of adjusting display contrast and requiring no externally attached components. A resistor formed by four serially connected resistor elements R1 has one end connected to a reference voltage VLCD0 applied from an operational amplifier 8, and the other end connected to an external variable resistor 25 through a terminal 24. Consequently, liquid crystal driving voltages VLCD0, VLCD1, VLCD2, VLCD3, and VLCD4 can be finely adjusted not only by eleven versions of reference voltage VLCD0 in accordance with voltages at respective connection points of twelve serially connected resistor elements, but by changing the resistance of the external variable resistor 25, to thereby provide a liquid crystal driving integrated circuit 1 that can be used for a variety of general purposes. Since only one external variable resistor 25 is required and this resistor is inherently variable, there is no need to consider variation in characteristics.

    • Increase in power consumption and increase in power supply noise of a serial data input system are suppressed, while clock skew is more easily prevented. The serial data input system of this invention includes a shift register that takes in and shifts serially transferred display data in synchronization with a clock SCL, a clock counter that counts the number of clock pulses of the clock SCL and outputs each of clock count signals BIT08, BIT16 and BIT24 when the counted number of the clock pulses of the clock SCL reaches each of count numbers 8, 16 and 24 respectively, and registers into each of which the data stored in the shift register is transferred and stored collectively and in parallel in response to each of the clock count signals BIT08, BIP16 and BIT24 respectively.
