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.

An electronic appliance, comprising

a display device configured to display a plurality of images,
wherein the display device includes:
a first image and a second image that are selectively displayed;
a first light-guiding layer disposed below a screen;
a second light-guiding layer disposed below the first light-guiding layer;
and
at least one light source disposed to selectively illuminate the first light-guiding layer and the second light-guiding layer,
wherein 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 at least one light source and introduced into the second light-guiding layer is greater than an intensity of light that is emitted from the at least one light source and introduced into the first light-guiding layer.

An electronic appliance, comprising:

a display device, wherein the display device includes:
a plurality of image implementing units that include a plurality of images that are selectively displayed, at least one light-guiding layer on which the plurality of images are provided and at least one light source that is provided to illuminate the at least one light-guiding layer;
a light shielding unit that separates adjacent ones of the plurality of image implementing units such that light emitted from any light source among the plurality of image implementing units and light emitted from any other light source among the plurality of image implementing units do not interfere with each other;
and
a printed circuit board that is disposed below a screen with the plurality of image implementing units and the light shielding unit in between,
wherein:
the plurality of image implementing units includes a first image implementing unit and a second image implementing unit disposed in a longitudinal direction of the printed circuit board, and
the light shielding unit is disposed between the first image implementing unit and the second image implementing unit.
