  • Patent number: 8854573
    Abstract: An electronic device including a display is provided. The display displays a received information content, and the information content has a horizontal direction. The display has a horizontal direction parallel to the information content's horizontal direction. The display includes a display panel, a backlight module and a first polarization unit. The backlight module is disposed at a side of the display panel, wherein the backlight module includes a horizontal prism sheet. The horizontal prism sheet includes a plurality of first prisms, wherein top angles of the first prisms are larger than or equal to 80 degrees and are smaller than 90 degrees. The display panel is located between the first polarization unit and the backlight module. A first angle between a transmission axis of the first polarization unit and the horizontal direction of the display is larger than 45 degrees and smaller than 135 degrees.

  • Patent number: 8684579
    Abstract: An electronic device includes a display module, a base and a keyboard module. The display module is pivoted on the base. The keyboard module is disposed on the base. The keyboard module has a plurality of keys. Each of the keys includes a main body and an imprinted structure. The main body has a top surface. The imprinted structure is disposed on the top surface of the main body and includes a light guiding portion and a light scattering portion. A light emitted by the display module illuminates the keyboard module. The light is guided towards a specific direction when the light passes through the light guiding portion, and the light is scattered in other directions when the light passes through the light scattering portion.
