Abstract
The present disclosure provides a display device and a driving method thereof. The display device has a first working mode and includes a display panel and a driving circuit board electrically connected to the display panel. In the first working mode, the driving circuit board is configured to perform an overcurrent protection on the display panel when a current in the signal line is greater than a preset current during at least two consecutive frames.
Claims9
A display device, having different working modes for executing different overcurrent protection operation processes comprising a first working mode applicable to a test of an electrostatic discharge capability of the display device, and comprising:
- a display panel comprising a signal line;
- and
- a driving circuit board electrically connected to the display panel,
- wherein in the first working mode, the driving circuit board is configured to perform an overcurrent protection on the display panel when a current in the signal line is greater than a preset current during at least two consecutive frames;
- wherein
- the driving circuit board is configured to determine whether the current in the signal line is greater than the preset current in one frame by determining whether an absolute value of the current in the signal line is greater than the preset current in two periods spaced apart within the frame;
- and/or
- the driving circuit board is configured to determine whether the current in the signal line is greater than the preset current in one frame by determining whether a case that the absolute value of the current of the signal line is greater than the preset current in the frame persists for at least a preset duration.
A driving method of a display device having different working modes for executing different overcurrent protection operation processes comprising a first working mode applicable to a test of an electrostatic discharge capability of the display device, comprising:
- acquiring, by a driving circuit board, a current in a signal line of a display panel;
- in the first working mode, determining, by the driving circuit board, whether the current in the signal line is greater than a preset current during at least two consecutive frames;
- and determining whether the current in the signal line is greater than the preset current in one frame by determining whether an absolute value of the current in the signal line is greater than the preset current in two periods spaced apart within the frame;
- and/or determining whether the current in the signal line is greater than the preset current in one frame by determining whether a case that the absolute value of the current of the signal line is greater than the preset current in the frame persists for at least a preset duration;
- and
- if yes, performing, by the driving circuit board, an overcurrent protection on the display panel.
