Patent ID: 8525768

Claim:
A display panel comprising a gate line circuit, the gate line circuit comprising: a gate driver having an output terminal for generating a first driving signal with alternate high and low levels, wherein the first driving signal has a first rising edge and a first falling edge; a control circuit having an input terminal connected to the output terminal of the gate driver for receiving the first driving signal and an output terminal for generating a second driving signal, wherein the second driving signal has a second rising edge and a second falling edge, and the second rising edge and the second falling edge of the second driving signal are respectively smoother than the first rising edge and the first falling edge of the first driving signal; and a gate line connected to the output terminal of the control circuit, wherein the control circuit comprises: at least one capacitor, the at least one capacitor is charged in a first direction in response to the first rising edge of the first driving signal, and the at least one capacitor is charged in a second direction in response to the first falling edge of the first driving signal; a first inverter having an input terminal connected to the input terminal of the control circuit; a resistor; and a second inverter having an input terminal connected to an output terminal of the first inverter through the resistor, wherein the at least one capacitor is interconnected between the input terminal of the second inverter and an output terminal of the second inverter, and the output terminal of the second inverter is connected to the output terminal of the control circuit.
