Abstract:
1. A gate driver suitable for use in a display device, wherein the display device includes a substrate adapted to have the gate driver mounted thereon, the substrate including a scan line, a compensating line, a data line, at least a first wiring line adapted to provide a first 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, the gate driver comprising: a first input buffer including a first operational amplifier, wherein the first operational amplifier has a first input connected to the first wiring line of the substrate to convert the first reference voltage into a first buffered voltage; a control circuit adapted to output at least one scan starting signal and compensating starting signal; a compensating output buffer adapted to receive the compensating starting signal and the first buffered voltage as a power voltage, and output a compensating signal on the compensating line of the substrate; and a scanning output buffer adapted to receive the scan starting signal and output a scan signal on the scan line of the substrate.
