Abstract: The present invention provides a source driver for driving a light emitting diode panel. The source driver includes a buffer including an output terminal; and a plurality of driving circuits coupled to the buffer. Each of the plurality of driving circuits includes a constant current transistor including a gate controlled by a node voltage of the output terminal of the buffer; and a compensation unit for compensating the node voltage of the output terminal of the buffer.

Abstract: The present invention provides a method of controlling a display panel. The display panel includes a plurality of subpixels and a plurality of scan lines coupled to the plurality of subpixels. The method includes steps of: scanning a first scan line among the plurality of scan lines to turn on at least one of the plurality of subpixels coupled to the first scan line during a subframe period among a display frame period; and discharging a second scan line among the plurality of scan lines during a non-display period following the subframe period. Wherein, the second scan line is different from the first scan line.
