发明名称 Display unit and display panel driver including operational amplifier to apply reference voltage to resistance ladder having impedance adjusting circuit
摘要 A display driver includes an operational amplifier which receives a gradation power source voltage and outputs a reference voltage, a resistance ladder which receives the reference voltage to generate a gradation voltage, and a resistor including a first end coupled to an output of the operational amplifier and a second end supplied with a voltage having the same potential as the reference voltage.
