Abstract:
1. A display device comprising: a pixel array including a plurality of pixels; a plurality of first signal lines disposed in the pixel array; a plurality of second signal lines disposed in the pixel array; a first driving circuit to output scanning signals to the plurality of first signal lines; and a second driving circuit to output display signals to the plurality of second signal lines; wherein each pixel of the plurality of pixels is operated in a normally black-displaying mode; wherein the first driving circuit repeats a first step of sequentially selecting N lines of the plurality of first signal lines and a second step of selecting Z lines of the plurality of first signal lines that are separate from the N lines, where N and Z are natural numbers; wherein the second driving circuit repeats outputting N times the display signals and outputting one time a blanking signal which masks an image displayed on corresponding pixels; and wherein the display signals outputted from the second driving circuit is delayed from a memory in which the display signals is stored in the vicinity of a boundary between one frame period and a frame period next to the one frame period within a time-sequential interval between the last of the blanking signal which is output in a certain frame period and the first of the blanking signal which is outputted in the next frame.
