摘要： A selector (103A) outputs a gray level voltage corresponding to pixel data (D-A) as drive voltage (Va). When the drive voltage (Va) is written in a source line (LineS-A), switches (105A-1, 105A-2) are ON while a switch (106A) is OFF. When the drive voltage (Va) written in the source line (LineS-A) is retained, the switches (105A-1,105A-2) are OFF while the switch (106A) is ON.

The current output part takes three operation modes. Under a voltage supply mode, the current output part receives a voltage from the voltage supply part and holds the voltage in the voltage holding capacitance element. Under a current supply mode, the current output part receives the current from the current supply part, generates a second voltage by the current-voltage converting function and holds the voltage in the voltage holding capacitance element. Under a current output part, the current output part outputs an output current according to the voltage held in the voltage holding capacitance element by the voltage-current converting function.

摘要： A switching-controlling section turns ON one of a transfer gate for high voltages or a transfer gate for low voltages and subsequently turns ON the other one of the transfer gates according to the outputs from the data latches only when the outputs from data latches are different from each other. Source lines are sequentially connected to a capacitor element for high voltages or a capacitor element for low voltages. For those source lines in which applied voltages change in a previous period and a subsequent period, an electric charge is stored and supplied effectively and power consumption is reduced, whereas for those source lines in which the applied voltages do not change, retained voltages do not vary so power is not consumed when subsequent voltages are applied. Power consumption in a liquid crystal panel driving device is reduced, and the time required for storing and supplying an electric charge is shortened. The circuit scale is also reduced.
