Scan driver and related display apparatus

A display apparatus comprising:

• a display panel comprising a plurality of scan lines, a plurality of data lines and a plurality of pixels connected to the plurality of scan lines and the plurality of data lines;
• a scan driver comprising a plurality of stages, the plurality of stages being connected to the plurality of pixels through the plurality of scan lines, the plurality of stages being sequentially disposed;
• and
• a data driver configured to provide data voltages to the plurality of data lines,
• wherein each of the stages comprises a signal output part configured to output a scan writing signal to a corresponding scan line,
• wherein a buffer size of the signal output part of an x-th stage of the stages is unequal to a buffer size of the signal output part of a y-th stage of the stages,
• wherein x is a natural number, and
• wherein y is another natural number.

A scan driver comprising:

• a first stage comprising a first output part, the first output part comprising a first output transistor and configured to provide a first signal, the first output transistor having a first buffer value;
• a second stage electrically connected to the first output transistor, configured to receive a copy of the first signal, and comprising a second output part, the second output part comprising a second output transistor and configured to provide a second signal, the second output transistor having a second buffer value;
• and
• a third stage electrically connected to the second output transistor, configured to receive a copy of the second signal, and comprising a third output part, the third output part comprising a third output transistor and configured to provide a third signal, the third output transistor having a third buffer value, at least one of the second buffer value and the third buffer value being unequal to the first buffer value.
