Abstract:
1. A display device comprising a plurality of scanning signal lines and a plurality of data signal lines, the data signal lines being provided to pixel arrays in such a manner that first and second pixel arrays being adjacent to each other and each including a plurality of pixels are provided with two data signal lines each, wherein each pixel includes one or plural pixel electrodes; the scanning signal lines are selected in such a manner that every N number of the scanning signal lines are selected concurrently (N is an integer of 1 or greater); each of the first and second pixel arrays is such that one pixel electrode contained in one of two pixels arranged in sequence and one pixel electrode contained in the other one of the two pixels arranged in sequence are connected with different ones of the data signal lines via respective transistors; a transistor connected with the one pixel electrode contained in the one of two pixels arranged in sequence, and a transistor connected with the one pixel electrode contained in the other one of the two pixels arranged in sequence are connected respectively with the N number of scanning signal lines selected concurrently; the display device performs correction of input gray scales of data signals inputted to the display device externally, the display device performing the correction in such a manner that when the input gray scales of the data signal inputted to the display device externally so as to be supplied respectively to the pixel electrodes contained in the two pixels arranged in sequence are different from each other, both the input gray scales are corrected so as to cause the gray scale difference between post-correction gray scales to be greater than the gray scale difference between the input gray scales; and, the display device displays with the post-correction gray scales, wherein the display device further comprises a correction circuit for correcting gray scales of the data signals, and when the correction circuit corrects the input gray scale of the one of the two pixels arranged in sequence, the correction circuit corrects the input gray scale on the basis of the input gray scale of the other one of the two pixels arranged in sequence, wherein the post-correction gray scale is calculated from the following Formula: where: the target pixel is that one of the two pixels arranged in sequence, whose input gray scale is to be corrected; and the comparative pixel is that one of the two pixels arranged in sequence which is to be compared with the target pixel in correcting the input gray scale of the target pixel.
