DRIVER FOR DISPLAY APPARATUS

摘要

A driver for a display device is provided to prevent an LCD device from being damaged by an excessive source voltage by lowering an operation voltage of the LCD device, when an operation voltage for a source driver is close to a bonding temperature. A driver for a display device includes a current source(210), a current mirror circuit(220), a thermistor(225), a reference resistor(226), and an output terminal(203). The current mirror circuit delivers the current from the current source to first and second nodes. The thermistor is connected between the first node and a ground voltage and has a resistance varied according to a peripheral temperature. The reference resistor is connected between the second node and the ground voltage and has a predetermined reference resistance. The output terminal outputs the voltage of the second node to the outside.
