  • Patent number: 11778109
    Abstract: A display apparatus includes a display device, a detection device, and a control device that acts as a controller. The controller displays a predetermined image on the display device, calculates, upon detecting a loop and a user's eye inside the loop through the detection device, a relative size of the user's eye with respect to the loop, as a reference size, causes the display device, upon detecting through the detection device that the relative size has changed to a size larger than the reference size, to enlarge the predetermined image, in proportion to a difference between the relative size and the reference size, and causes the display device, upon detecting through the detection device that the relative size has changed to a size smaller than the reference size, to reduce the predetermined image, in proportion to a difference between the relative size and the reference size.

  • Patent number: 11769454
    Abstract: A display panel and a display device having an emission control driver are discussed. The display device can include a display panel for displaying an image through sub pixels, and an emission control driver configured to supply a plurality of emission control signals to the sub pixels. The emission control driver can include a plurality of emission control stages configured to supply the plurality of emission control signals, respectively. Each emission control stage can include an output buffer including a first pull-up transistor configured to output a first high potential power supply voltage to an output line by a Q node, and a first pull-down transistor configured to output a first low potential power supply voltage to the output line by a QB node.
