Abstract
The control circuit for controlling a display panel is provided. The control circuit includes a first driving circuit and a second driving circuit for driving the display panel. The first driving circuit includes first output terminals and first input terminals. The first driving circuit outputs a plurality of test signals to the first output terminals sequentially during different periods in a diagnosis stage. The second driving circuit includes second input terminals and second output terminals. The second driving circuit receives the test signals through the second input terminals in the diagnosis stage, and outputs a plurality of response signals to the second output terminals sequentially during different periods in response to the test signals. The first driving circuit receives the response signals through the first input terminals, and judges a connecting status of the first driving circuit and the second driving circuit according to the response signals.
