Abstract
Currently most 3d device developer realize that for auto stereoscopic displays separate images for right and left eyes are required. The consequence is a 3D image quality reduction, because of the decrease in resolution and viewing angle. For the most well-known schemes, such as parallax barrier, lenticular screens, etc., the resolution decreases by up to 50%. Additionally, because of the listed devices' inherent rather narrow viewing angle, head-tracking devices are required. In contrast, the neuro-stereo display, proposed by the authors of this paper, will increase resolution without reducing viewing angles. This advantage exists because neuro-stereo displays create one continuous 3d image, which uses all the information contained in the initial stereo pair. The presented modification of this neuro-stereo display, SmartrON consists of three LCD panels. The value of further increases in the number of LCD panels is limited by the power of the backlight. Besides, it is unclear if additional LCDs will increase the quality of the 3D effect. On the three LCD devices, images displayed on each panel are processed with a special neural network, so that the resulting luminous flux exactly corresponds to the amount of light in the scene's objects, with a rather wide viewing angle. Considering the mathematical aspect, a new method is proposed for coding the part of 3D space that is superimposed on two or three 2D fields. So we can talk about a new method of holography in incoherent light. The neural network can be emulated either using serial processors or standard graphics cards which provide the real-time mode. The results ofnumerical simulations and physical experiments show that the three LCD panel device appreciably increases the quality of 3d images in comparison with the two-panel scheme.
