  • Patent number: 10861404
    Abstract: A display device according to an embodiment of the disclosure includes a first driver that sequentially selects each of pixels on a row basis, and a second driver that applies, through a signal line, an image signal to each of the pixels in a pixel row that is selected by the first driver, and that inverts a polarity of the image signal at a predetermined period. The second driver sequentially applies, to the signal line, a first precharge signal voltage having a relatively large amplitude and a second precharge signal voltage having a relatively small amplitude, prior to the application of the image signal. The second driver further controls the application of the first precharge signal voltage to cause an amount of leak of an electric current from the pixel to the signal line due to the application of the first precharge signal voltage to become smaller than that in another period for each of predetermined horizontal periods.
