  • Publication number: 20150279318
    Abstract: A display apparatus is provided. A display apparatus includes a display panel including a plurality of subpixels, the plurality of subpixels including red (R) subpixels, green (G) subpixels, and blue (B) subpixels, a panel driver configured to drive the display panel, and a controller configured to control the panel driver to, in one image frame section, sequentially turn on a first group of subpixels of the plurality of subpixels based on a predetermined group unit, and turn on a second group of subpixels of the plurality of subpixels which is in a location shifted by a predetermined subpixel unit with respect to the first group of subpixels. Accordingly, even though a LED display panel displays an image, decrease in resolution may be prevented. In addition, a bezel-less display apparatus may be realized using the LED display panel.
