An operational amplifying device comprises an input stage and an output stage. The input stage receives and processes an input voltage to output an amplified voltage. The output stage is electrically connected to the input stage in series. The output stage comprises a first switch and a second switch. The first switch is configured to turn on for transferring the amplified voltage. The second switch is connected in parallel with the first switch and is configured to turn on for transferring the amplified voltage. The second switch is turned off when the first switch is turned on such that the amplified voltage is transferred through the first switch to the first resistor array for gamma correction.
