Discharge circuit, display panel and display device

The utility model provides a discharge circuit, display panel and display device, the discharge circuit includes a control module, connects the enable signal end respectively, black matrix and earth potential, and when the beginning of start drive signal STV signal, control enable signal makes black matrix and earth potential switch on in the time of predetermineeing after the start to the inducedcharge that produces on the in -process black matrix of will starting shooting dredges the earth potential, through this discharge circuit can fundamentally to solve the start white line bad. 本实用新型提供了种放电电路、显示面板和显示装置，所述放电电路包括控制模块，分别连接使能信号端，黑色矩阵以及地电位，当开机驱动信号STV信号开始时，控制使能信号使黑色矩阵和地电位在开机后的预设时间内导通，从而将开机过程中黑色矩阵上产生的感应电荷疏导到地电位，通过该放电电路可以从根本上解决开机白线不良。
