    Abstract: A light emitting display is configured to reduce or prevent motion blur by shortening a time that a black frame is displayed between image frames. One embodiment includes display region, a data driver, a scan driver, and a controller. The display region displays frames of images according to a data signal and a scan signal. The data driver transmits data for displaying first frames and second (black) frames between the first frames. The scan driver includes first and second scan driving circuits for transmitting scan signals, and a switch unit for selectively coupling the first and second scan driving circuits. The scan driver transmits scan signals sequentially during the first frames and transmits scan signals to at least two of the scan lines concurrently by driving the first and second scan driving circuits in parallel during the second frames.

  • Patent number: 8730579
    Abstract: An optical sheet includes a base film in which light is incident from a lower side, a plurality of prism patterns and a diffusion member. The prism patterns are protruded to be spaced apart from each other on the base film to enhance the front luminance of light incident from the lower side of the base film. The diffusion member is disposed between prism patterns to have a diffusion surface in parallel with the base film. The diffusion member includes a plurality of diffusion dots capable of enhancing the luminance uniformity of light incident from the lower side of the base film. Thus, front luminance and luminance uniformity may be enhanced due to a juxtaposition of the prism patterns and the diffusion portion, and the viewing angle of the LCD device may be enhanced.
