Problems solved by technology
[0002] At present, the driving circuit board that drives the display panel to realize the display function often has a sudden change in current due to various reasons, and the large current generated by the sudden change will cause damage to the control module in the display panel or even the entire display panel. After the display panel is burnt, it often takes a long time of debugging and analysis to determine that the control module in the display panel or the display panel has been burned, which greatly increases the detection time and cost of the display panel, so how to avoid the above-mentioned problems during the development and verification stage Damage to the control module or display panel in the display panel caused by sudden large current is critical

Embodiments of the present invention disclose a driving circuit of a display panel and a display panel. The drive circuit includes a control module, the control module includes an enable signal input end and a power signal output end, the control module is used to provide a power signal to the display panel; the detection module, the detection module includes an enable signal output end and a power signal input end, The enable signal output terminal is electrically connected to the enable signal input terminal, and the power signal output terminal is electrically connected to the power signal input terminal; the detection module is used for passing the enable signal when the power signal input at the power signal input terminal is greater than the set power signal The output terminal outputs the enable signal to the enable signal input terminal, and the control module is used for controlling the power signal output terminal to terminate the output power signal according to the enable signal input from the enable signal input terminal. Through the technical solution of the present invention, the problem of damage to the control module or the display panel caused by the abnormality of the power signal output by the control module is effectively avoided.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a driving circuit of a display panel and a display panel. Background technique [0002] At present, the driving circuit board that drives the display panel to realize the display function often has a sudden change in current due to various reasons, and the large current generated by the sudden change will cause damage to the control module in the display panel or even the entire display panel. After the display panel is burnt, it often takes a long time of debugging and analysis to determine that the control module in the display panel or the display panel has been burned, which greatly increases the detection time and cost of the display panel, so how to avoid the above-mentioned problems during the development and verification stage The control module in the display panel or the damage of the display panel caused by sudden large current is very impor...
