Display apparatus, and driving circuit for the same |
摘要 |
A drive circuit which outputs an output signal to an output terminal, includes a drive transistor configured to output a gradation current to the output terminal; a single differential amplifier; a resistance element connected with the drive transistor; and a plurality of switches. The plurality of switches are controlled such that a precharge voltage is outputted from the differential amplifier to the output terminal in a first period while blocking off an output from the drive transistor and such that a gradation current is outputted from the drive transistor to the output terminal in a second period after the first period.
