A display has a display panel of a first aspect ratio and is able to display on the display panel an image of a second aspect ratio whose width element is larger than that of the first aspect ratio. The display has a gate driver, a data driver, and a timing controller. The gate driver sequentially selects gate lines of the display panel. The data driver stores data for one gate line and supplies the data to one of the gate lines selected by the gate driver. The timing controller supplies control signals to the gate and data drivers so that predetermined data is displayed in top and bottom non-image areas of the display panel during a vertical blanking period. The display is capable of displaying images of different sizes.

Display and method of and drive circuit for driving the display

The present gamma correction circuit is provided with a memory for supplying correction data for the gamma correction of the luminance of a display means, and a selector for selecting either from N-bit uncorrected digital display data and corrected data for outputting as driving data for the display means. A liquid crystal driver is provided with gamma correction means for gamma-correcting the luminance of a liquid crystal panel inputting the N-bit digital display data for liquid crystal displaying and means for converting the N-bit digital display data into analog data, the gamma correction means comprises a gamma correction circuit of the invention. A liquid crystal display device is provided with a liquid crystal display panel inputting the N-bit digital display data for liquid crystal displaying, and gamma correction means or a liquid crystal driver for gamma-correcting the luminance of the liquid crystal display panel. The gamma correction means or the liquid crystal driver comprises a gamma correction means or a liquid crystal driver of the present invention.
