Abstract:
1. A control circuit for driving a display panel, comprising: a timing controller, outputting a timing control signal in response to a frame data; and a driving module, coupled to the timing controller and the display panel for driving the display panel in response to the timing control signal, wherein the timing controller is switchable to a modifying state according to a driving condition of the driving module, the driving module comprises: a driving unit, electrically coupled to the timing controller and the display panel for outputting a driving signal to drive the display panel in response to the timing control signal; and a driving-condition detecting unit, electrically coupled to the timing controller and the driving unit for detecting the driving condition of the driving unit, and outputting an indicating signal indicating the driving unit in an abnormal state to control the timing controller to operate in the modifying state, wherein the driving-condition detecting unit comprises at least one detector, and the detector comprises: a detecting element, electrically coupled to one of the drivers for detecting the driving condition and outputting a signal when the driving condition is detected to be abnormal; and a logic gate communicable with the detecting element for operating the signal from the detecting element into the indicating signal; wherein one input terminal of the logic gate is coupled to an output terminal of another detector.
