Publication number: 20080309600Abstract: A display apparatus includes pixels, a signal controller, a gray-scale voltage generator, and a data driver. The signal controller converts input image signals having a first frame frequency to first and second output image signals having a second frame frequency. The second output image signal is an interpolation between the input image signal for the present frame and an input image signal for a next frame after the present frame. The gray-scale voltage generator outputs a first gray-scale voltage group and a second gray-scale voltage group. The data driver converts the first output image signal to a first data voltage based on the first gray-scale voltage group and converts the second output image signal to a second data voltage based on the second gray-scale voltage group, and outputs the first and second data voltages to the pixels in a present frame.Type: ApplicationFiled: January 11, 2008Publication date: December 18, 2008Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Jun-Woo LEE, Hee-Seop KIM, Hyeok-Jin LEE, Ji-Won SOHN
