Abstract: A gate driver, a configuration system, and configuration method thereof is provided. The gate driver is used for providing a gate drive signal for a TFT array substrate and comprises at least a drive capability detection module and a drive capability adjustment module. The configuration system is configured to configure the driving capabilities of a plurality of gate drivers and comprises a controller provided outside the plurality of gate drivers. The driving capability of the gate driver becomes adjustable and configurable. The well balance of the drive capabilities of the drive control signals received by the different TFT array regions driven by the plurality of gate drivers configured by the configuration system can avoid the occurrence of a splitting-screen phenomenon.
