Liquid crystal display and method for generating 3d images by matching a software optical grating

A liquid crystal display for generating 3D images by matching a software optical grating, comprising:

• a backlight module for generating a light source;
• and
• a LCD panel including a color filter and adjacent to the backlight module, wherein the LCD panel includes a plurality of first subpixels mated with each other for generating a first image, a plurality of second subpixels mated with each other for generating a second image, and a plurality of third subpixels mated with each other for generating a black barrier image as the software optical grating, and the first subpixels, the second subpixels and the third subpixels are arranged as a matrix;
• wherein when the first image, the second image and the black barrier image are concurrently generated by the liquid crystal display, the black barrier image is slightly spread to cover one part of the first image and one part of the second image, thus the first image is covered partially by the black barrier image for generating a right-eye image, the second image is covered partially by the black barrier image for generating a left-eye image, and the right-eye image and the left-eye image are concurrently generated by the liquid crystal display and respectively projected onto a right eye and a left eye of a viewer.

A method for generating 3D images by matching a software optical grating, comprising:

• providing a liquid crystal display including a backlight module for generating a light source and a LCD panel including a color filter and adjacent to the backlight module, wherein the LCD panel includes a plurality of first pixels, a plurality of second pixels and a plurality of third pixels, and the first pixels, the second pixels and the third pixels are adjacent to each other and arranged as a matrix, wherein each first pixel has at least three first subpixels adjacent to each other, each second pixel has at least three second subpixels adjacent to each other, and each third pixel has at least one third subpixel;
• switching the liquid crystal display to a 2D image display mode or a 3D image display mode, wherein when the liquid crystal display is switched to the 3D image display mode, the first subpixels of the first pixels are mated with each other for generating a first image, the second subpixels of the second pixels are mated with each other for generating a second image, and the third subpixels of the third pixels are mated with each other for generating a black barrier image as the software optical grating, wherein when the first image, the second image and the black barrier image are concurrently generated by the liquid crystal display, the black barrier image is slightly spread to cover one part of the first image and one part of the second image;
• and
• partially covering the first image by the black barrier image for generating a right-eye image, and partially covering the second image by the black barrier image for generating a left-eye image, wherein the right-eye image and the left-eye image are concurrently generated by the liquid crystal display and respectively projected onto a right eye and a left eye of a viewer.
