  • Patent number: 10991329
    Abstract: A control circuit according to an embodiment of the disclosure performs control of active matrix driving by a field inversion driving method to cause a vertical effective display period in one field period to be close to a start time of the one field period upon observation of a waveform of a signal outputted from the control circuit with display resolution of 200 ?sec or display resolution lower than display resolution of 200 ?sec. The one field period is defined by a vertical start signal.

  • Patent number: 10991309
    Abstract: A light emitting element display device with a narrow frame and high light emission efficiency is provided even when high definition is achieved. The light emitting element display device includes: a light emitting element which emits light at each of a plurality of subpixels forming one pixel; a drive transistor in which one of a source and a drain is connected to an anode of the light emitting element; and an output control circuit which selectively sets the other of the source and the drain of the drive transistor into one of a state of being connected to a power-supply voltage, a state of being connected to a reset voltage that is a lower voltage than the power-supply voltage, and a high-impedance state of not being connected to any of these voltages.

  • 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.
