Patent ID: 8294753

Claim:
An image display device, comprising: a lenticular lens array; a first backlit display element that is positioned on the lenticular lens array and is driven at a frame frequency of N×60 Hz, where N is an integer equal to or greater than 2; and a light source module that is positioned under the lenticular lens array and irradiates light onto the lenticular lens array using a plurality of electrically individually controllable pixels, wherein the first backlit display element displays a video signal of a 2-dimensional (2D) format in a 2D mode and displays a video signal of an N-view 3-dimensional (3D) format in a 3D mode, wherein the light source module irradiates light in the form of a surface light source onto the lenticular lens array in the 2D mode and irradiates light in the form of a plurality of line light sources, that are spaced apart from one another at a uniform distance, onto the lenticular lens array in the 3D mode, and wherein a number of subpixels included in each pixel of the light source module is N in the 3D mode when a frame frequency of each of the first backlit display element and the light source module is N×60 Hz.
