  • Patent number: 9711102
    Abstract: A method of differently producing driving clock signals for a shift register of a gate lines driving circuit of a Liquid Crystal Display (LCD), the method includes the steps of determining whether an ambient temperature is greater than or not in comparison to a predetermined threshold temperature; in response to the determining indicating that the ambient temperature is greater, using a first ON voltage and a first charge canceling method; and in response to the determining indicating that the ambient temperature is not greater, using a second ON voltage and a second charge canceling method, where the second ON voltage is different from the first ON voltage and where the second charge canceling method is different from the first charge canceling method. The second charge canceling method may have a shorter duration than that of the first charge canceling method. The second ON voltage may be greater than the first ON voltage.

  • Patent number: 9589516
    Abstract: A method of driving a display panel, the method including outputting video data to a display panel during an N-th (N is a natural number) frame, outputting video data to the display panel during an (N+1)-th frame, comparing polarities of video data of the N-th frame and corresponding polarities of video data of the (N+1)-th frame, and controlling polarities of video data of an (N+2)-th frame, according to the result of the comparison.

  • Publication number: 20150170598
    Abstract: A method of driving a display panel includes comparing a previous frame data and a present frame data, outputting an inversion control signal of the present frame based on a result of the comparing the previous frame data and the present frame data, generating a positive pixel voltage and a negative pixel voltage based on the inversion control signal and displaying an image based on the positive pixel voltage and the negative pixel voltage.
