The principle construction of the unique autostereoscopic 3D LCD wall is considered. This glasses-free 3D LCD wall provides presentation of high-quality stereo images for many users simultaneously. The technical characteristics of the 3D LCD wall are compared with the corresponding parameters of the multiview 3D projection wall. The general equation for the evaluation of the multiview stereo image in this 3D LCD wall will be presented and all of its parameters are analysed. We introduce here the fundamental matrices, in which will be contained the information about the contribution of the different views in every subpixel. The properties of these matrices as well as their use for the evaluation of the stereo-image are considered. The problem of the adjustment of the stereoscopic image on the 3D LCD wall is also discussed and different types of adjustment are considered. For some of them the corresponding equations are given. The presented approach may be applied also to the case of the multiview autostereoscopic 3D plasma wall.
