1. A gate driver, comprising:
a scan signal generating unit having a plurality of output channels, used for sequentially outputting a scan signal through the output channels according to a basic clock and a start pulse; and a compensation unit coupled to the output channels, used for compensating a total resistance of each of the outputting channels, and sequentially receiving and transmitting the scan signal to a display panel, wherein the compensation unit comprises:
a plurality of compensation circuits respectively corresponding to the output channels, each of the compensation circuits comprising:
a buffer having an input terminal used for receiving the corresponding scan signal;a first resistor having a first terminal coupled to an output terminal of the buffer;a second resistor having a first terminal coupled to a second terminal of the first resistor;a third resistor having a first terminal coupled to a second terminal of the second resistor, and a second terminal coupled to the display panel;a first switch having a first terminal coupled to the first terminal of the first resistor, a second terminal coupled to the second terminal of the first resistor, and a control terminal used for receiving a first external configuration signal;a second switch having a first terminal coupled to the first terminal of the first resistor, a second terminal coupled to the second terminal of the second resistor, and a control terminal used for receiving a second external configuration signal; anda third switch having a first terminal coupled to the first terminal of the first resistor, a second terminal coupled to the second terminal of the third resistor, and a control terminal used for receiving a third external configuration signal. |
