Abstract
A liquid crystal display for recognizing a flicker with the naked eyes in a step of inspecting a flicker in the case where a liquid crystal display is driven with a frame frequency of 120 Hz is disclosed. In the liquid crystal display, a timing controller supplies a first frame inversion polarity signal which is used at a first frame inversion and, at the same time supplies a gate start pulse which indicates a supply of a scanning pulse. A frame polarity signal converting means converts a first frame inversion polarity signal into a second frame inversion polarity signal in response to the gate start pulse. And a data driver changes the inputted frame into a second frame inversion in response to the second frame inversion polarity signal.
Claims31
A liquid crystal display, comprising:
- a timing controller that supplies a first frame inversion polarity signal which is used at a first frame inversion and, supplies a gate start pulse which indicates a supply of a scanning pulse;
- a frame polarity signal converting means that converts a first frame inversion polarity signal into a second frame inversion polarity signal in response to the gate start pulse;
- and
- a data driver that changes the inputted frame into a second frame inversion in response to the second frame inversion polarity signal.
A liquid crystal display, comprising:
- a first signal generating means that generates a first period signal and a first inversed period signal in accordance with a gate start pulse;
- a second signal generating means that generates a second period signal and a second inversed period signal in accordance with the first period signal;
- and
- a third signal generating means that generates a second frame inversion polarity signal using the second period signal and the first frame inversion polarity signal.
A method of driving a liquid crystal display, comprising:
- generating a 1 frame inversion polarity signal which is used at a 1 frame inversion and a gate start pulse that indicates a supply of a scanning pulse;
- converting the 1 frame inversion polarity signal into a second frame inversion polarity signal in response to the gate start pulse;
- and
- changing the inputted frame to a second frame inversion in response to the 2 frame inversion polarity signal.
