  • Patent number: 11972718
    Abstract: A display device displays an image in which each frame is formed by at least two subframes. The display device includes a drive unit configured to drive a plurality of pixels in a pixel array so as to drive pixels in at least two rows based on pixel data of each row of each supplied subframe data. The drive unit drives the plurality of pixels so as to cause pixels in a row not matching a row in the supplied current subframe data to emit light with a first condition, and cause pixels in a row matching the row in the current subframe data to emit light with a second condition. The second condition is a condition in which a light emission amount is larger than in the first condition when causing the pixels to emit light in accordance with identical pixel values.

  • Patent number: 11971670
    Abstract: An image forming apparatus includes an intermediate transfer belt, an outer roller, a power source, and a regulation member. The outer roller transfers a toner image onto a recording material. The power source applies a voltage to the outer roller. The regulation member regulates orientation of the recording material. Information is acquired regarding a timing at which orientation of a recording material first portion, passing through the transfer portion that is located between the outer roller and the regulation member, can change to move closer to the intermediate transfer belt. Based on the acquired information, a transfer voltage target value for transfer onto the recording material is changed between a first target value of a period anterior to the timing and a second target value of a period posterior to the timing that is larger in absolute value than the first target value.
