  • Patent number: 9989694
    Abstract: There is provided an electronic appliance having an improved structure enabling multi-image conversion. The electronic appliance includes a display device configured to display a plurality of images, wherein the display device includes first and second images that are selectively displayed on a screen. A first light-guiding layer is disposed between the screen and a second light-guiding layer, and two light sources disposed to selectively illuminate the first light-guiding layer and the second light-guiding layer. The second light-guiding layer has a thickness that is 25% to 45% greater than a thickness of the first light-guiding layer such that an intensity of light that is emitted from the first light source and introduced into the second light-guiding layer is greater than an intensity of light that is emitted from the second light source and introduced into the first light-guiding layer.
