Patent ID: 8542224

Claim:
A clip system of a display, connected to a gate driver circuit of the display, comprising: a timing controller, for generating a first output enable signal, a first clip trigger signal, and a base working signal whose frame rates are the same as a frame rate of a system input signal according to the system input signal, and outputting the first output enable signal, the first clip trigger signal, and the base working signal, wherein the timing controller adjusts the first output enable signal and the first clip trigger signal to a second output enable signal and a second clip trigger signal for outputting according to the change of the frame rate when the frame rate of the system input signal changed; and a clip module, for receiving the base working signal, the first output enable signal, and the first clip trigger signal, adjusting the base working signal by using the first output enable signal and the first clip trigger signal to form a first clip voltage and output the first clip voltage to the gate driver circuit, receiving the second output enable signal and the second clip trigger signal, and adjusting the base working signal by using the second output enable signal and the second clip trigger signal to form a second clip voltage equal to the first clip voltage and output the second clip voltage to the gate driver circuit, wherein a trigger time length of the first clip trigger signal equals a trigger time length of the second clip trigger signal, a trigger time length of the first output enable signal equals a trigger time length of the second output enable signal, a time interval between a trigger point of the first clip trigger signal and a trigger point of the first output enable signal equals a time interval between a trigger point of the second clip trigger signal and a trigger point of the second output enable signal, so that a charging time length and charging charges of a liquid crystal element connected to the gate driver circuit remain the same.
