Abstract: The present invention provides a display panel driving circuit and compensation method thereof. The display panel driving circuit comprises a near end load, a far end load, an operating circuit and a pre-charging control circuit. The operating circuit is configured to receive display data. The pre-charging control circuit is coupled to the near end load and the far end load respectively. The pre-charging control circuit outputs a first signal and a second signal to the near end load and the far end load respectively according to the display data that a first waveform from the near end load is the same as a second waveform from the far end load.

Abstract: A display device of the present invention includes a display substrate and a source driver. The display substrate includes a display area and a peripheral area surrounding the display area. At least a fan-out portion is formed on the peripheral area and distributes along a first direction. The fan-out portion has a plurality of fan-out wires. The source driver is connected to one side of the fan-out portion opposite to the display area. The source driver includes a plurality of driving circuits. An output end of each driving circuit has a modulation unit coupled to one of the plurality of the fan-out wires. The fan-out portion has a resistance value distribution along the first direction. The resistance value of the modulation unit in each driving circuit is modulated according to the resistance value distribution.
