3D image display device

A 3D image display device, comprising:

• a display module comprising a plurality of pixels and an image composed of the pixels, wherein the pixels is arranged in a first direction;
• and
• a first lenticular array comprising a plurality of strip-shaped first lenticular lenses and an angle between an extension direction of the first lenticular lens and the first direction is larger or equal to 45 degree;
• wherein the image composed of the pixels is created by the steps of:
• (a) providing a capture device, a subject to be captured, and a lenticular array, wherein the lenticular array comprises a plurality of strip-shaped lenticular lenses, a length of a bottom of each lenticular lens is 2L, and a center of the bottom is set as 0;
• (b) placing the capture device to aim at a top of one of the lenticular lenses and a point between −xL to xL of a bottom coordinate of the lenticular lens, and capturing the subject until a capturing for a plurality of pixels corresponding to the range from −xL to xL of the bottom coordinate of the lenticular lens is finished, wherein the value of x is smaller than 1 but greater than 0;
• (c) mapping pixels corresponding to the range from from −xL to 0 and from xL to 0 captured by the capture device to pixels corresponding to a range from −L to −xL and from L to xL of the bottom coordinate;
• and
• (d) repeating the steps (b) to (c) for the others of the lenticular lenses.
