1. A 3D display method, wherein: when display is driven, setting two adjacent sub-pixels in one row of sub-pixels as one group of sub-pixels so that every two adjacent groups of sub-pixels display different types of single-eye images, two sub-pixels in each group of sub-pixels display the same type of single-eye images, and each sub-pixel belongs to only one group of sub-pixels; and setting two adjacent sub-pixels other than the first sub-pixel at a beginning position and the last sub-pixel at an end position in each of two adjacent rows of sub-pixels next to said one row of sub-pixels as one group of sub-pixels so that every two adjacent groups of sub-pixels display different types of single-eye images, each of the two adjacent rows comprising three contiguous groups, two sub-pixels in each group of sub-pixels display the same type of single-eye images, each sub-pixel belongs to only one group of sub-pixels, and the first sub-pixel and the last sub-pixel display single-eye images, types of which are different from those displayed by their adjacent sub-pixels, respectively.
