Abstract
A method for driving a display panel includes generating a plurality of gate signals, providing the plurality of gate signals to a plurality of switching elements connected to a plurality of gate lines, respectively, providing the plurality of gate signals to a monitoring element, and restoring the plurality of switching elements based on an output signal from the monitoring element.
Claims20
A method for driving a display panel, the method comprising:
- generating a plurality of gate signals;
- providing the plurality of gate signals to a plurality of switching elements connected to a plurality of gate lines, respectively;
- providing a gate signal of the plurality of gate signals to a monitoring element;
- and
- restoring the plurality of switching elements based on comparison of an output signal of the monitoring element with an initial value, a maximum allowable value and a minimum allowable value of at least one of the plurality of switching elements.
