Display device and gate driver thereof

A display device comprising:

• a substrate including:
• a scan line formed in a first direction, and a compensating line substantially parallel to the scan line;
• a data line formed in a second direction;
• at least two wiring lines adapted to provide a first and a second reference voltage;
• and
• a pixel including a transistor and a storage capacitor, wherein a first end of the storage capacitor is connected to the data line via the transistor, and a second end of the storage capacitor is connected to the compensating line;
• a source driver assembled on the substrate and connected with the data line;
• and
• a gate driver assembled on the substrate, wherein the gate driver includes:
• a buffered voltage output module including two operational amplifiers having inputs respectively connected to the wiring lines of the substrate to receive the first and second reference voltages, wherein the operational amplifiers are configured to respectively convert the first and second reference voltages respectively into first and second buffered voltages;
• a compensating signal output module connected to the compensating line, wherein the compensating signal output module is adapted to receive the first and second buffered voltages as power voltages, and output at least one compensating signal on the compensating line;
• a scan signal output module connected to the scan line;
• and
• a control module connected to the scan signal output module and the compensating signal output module.
