1. A method for detecting gate line defects, comprising following operations:
upon receiving a startup signal, controlling a display panel to enter a self-checking mode;
performing row scanning on the display panel according to a first preset frame rate, wherein the first preset frame rate is greater than a normal frame rate when the display panel works normally; and
upon determining that the display panel is abnormal, issuing a prompt message;
wherein after the operation of upon determining that the display panel is abnormal, issuing a prompt message, the method further comprises:
controlling the display panel to close a self-checking interface and exit the self-checking mode.
 
8. A display panel, comprising: a memory, a main control circuit board, and a gate line defect detection program stored in the memory and executable by the main control circuit board, wherein when the gate line defect detection program is executed by the main control circuit board, following operations of a method for detecting gate line defects are realized:
upon receiving a startup signal, controlling a display panel to enter a self-checking mode;
performing row scanning on the display panel according to a first preset frame rate, wherein the first preset frame rate is greater than a normal frame rate when the display panel works normally; and
upon determining that the display panel is abnormal, issuing a prompt message.
 
14. A non-transitory computer-readable storage medium, storing a control program of a method for detecting gate line defects, when the control program of the method for detecting gate line defects is executed by a main control circuit board, following operations of the method for detecting gate line defects are realized:
upon receiving a startup signal, controlling a display panel to enter a self-checking mode;
performing row scanning on the display panel according to a first preset frame rate, wherein the first preset frame rate is greater than a normal frame rate when the display panel works normally; and
upon determining that the display panel is abnormal, issuing a prompt message.
