Patent ID: 8780013

Claim:
An image display device, comprising: a pixel representation unit to control respective representation of at least one pixel unit of an input image comprising a plurality of frames; a backlight unit to selectively generate a plurality of directional lights based on a number of views of the input image, and to apply the generated plurality of directional lights to the pixel representation unit, wherein the backlight unit includes a light source to emit light and a variable scattering layer to generate the plurality of directional lights by scattering the emitted light; and a controller to control a scattering pattern to scatter the emitted light based on a predetermined time-division scheme for the input image, wherein the controller controls a scattering pattern to scatter emitted light from a first plurality of light scattering areas of the variable scattering layer, corresponding to a first frame from among the plurality of frames, and applies first image data corresponding to the scattering pattern to the pixel representation unit, at a time interval synchronized with the first frame, and controls a scattering pattern to scatter the emitted light from a second plurality of light scattering areas of the variable scattering layer, corresponding to a second frame from among the plurality of frames, and applies second image data corresponding to the scattering pattern to the pixel representation unit, at a time interval synchronized with the second frame, wherein the predetermined time-division scheme, for a three-dimensional (3D) input image, includes emitting light from at least four scattering areas for each frame and is based on a 3D image angle and the number of views, wherein the number of views is greater than two.
