一种驱动电路、显示面板、显示装置及其控制方法
摘要：
本发明提供了一种驱动电路、显示面板、显示装置及其控制方法。所述驱动电路包括逻辑板、栅极驱动电路和接口控制模块；所述接口控制模块，用于检测由所述逻辑板输入至所述栅极驱动电路的时序控制信号；当所述时序控制信号不满足预置条件时，控制所述逻辑板的信号传输接口关闭，停止向所述栅极驱动电路输出信号，从而使得栅极驱动电路在时序控制信号异常时不工作，保护了栅极驱动电路的安全，实现了安装有该驱动电路的显示面板的自动保护，保证了驱动电路、显示面板以及显示装置的使用寿命。
摘要（英）：

The invention provides a drive circuit, a display panel, a display device and a control method thereof. The drive circuit includes a logic board, a gate drive circuit, and an interface control module. The interface control module is used for detecting a timing control signal input from the logic board to the gate drive circuit, and when the timing control signal does not satisfy a preset condition, making the signal transmission interface of the logic board closed to stop outputting a signal to the gate drive circuit. Therefore, the gate drive circuit does not work when the timing control signal is abnormal, and the safety of the gate drive circuit is protected. The display panel equipped with the drive circuit has an automatic protection function. The service life of the drive circuit, the display panel and the display device is ensured.
