Display device driver circuit

摘要

A display device driver circuit including a first switching circuit for switching connection and disconnection between an output terminal and a first source line; a second switching circuit for switching connection and disconnection between the output terminal and a second source line; and a selecting circuit for switching a voltage output from the output terminal by controlling the first and second switching circuits. The selecting circuit controls the first and second switching circuits so that the timing for opening one of the switching circuits is faster than the timing for closing the other of the switching circuits. Consequently, a time when both switches are open occurs regularly when the voltage output is switched, so that no current will pass between the switching circuits.
