Publication number: 20110234569Abstract: A data line driving section (6) outputs a video signal voltage for each pixel to a data line (DL) for each predetermined period in order. In outputting a video signal voltage for a pixel, the data line driving section (6) outputs a gradation signal voltage having a voltage corresponding to a gradation value of the pixel as the video signal voltage during a second part of the predetermined period, and outputs a correction gradation signal voltage different from the gradation signal voltage as the video signal voltage during a first part of the predetermined period. A control section (4) changes a relationship between the correction gradation signal voltage and the gradation signal voltage based on a combination of the gradation value of the pixel and a gradation value of a pixel preceding the pixel.Type: ApplicationFiled: March 18, 2011Publication date: September 29, 2011Inventors: Yoshihisa OOISHI, Misa Owa, Junichi Maruyama, Goki Toshima
