Realize in the prior art of 3-D display, holographic color three dimension display mainly contains following several scheme:
Solution 1: use a kind of stereoscopic vision display system, then right and left eyes plane projection view stereoscopic is appearsed as picture by picture processed, makes spectators produce three-dimensional depth to image.
Problems existing is, the mobile range of observer's sight line is limited, and visual range is narrower, and observer needs to wear special glasses or the helmet etc., therefore causes again long-time load weight to cause physiology senses of discomfort such as having a dizzy spell, the shortcoming such as cannot to move arbitrarily.
Existing solution 2: particular solid medium is full of one piece of region in three dimensions, then excites voxel to combine selectively, makes it luminous on request, and composition three-dimensional voxel array forms 3-D view.
Problems existing is, without suitable driving source and the luminescence medium with abundant light conversion efficiency, number of pixels is insufficient, complicated image information or the luminous point information of activity cannot be stated, many physics and technical limitation make that the experimental provision indication range built up is little, resolution is low, not easily realizes the true 3-D display of large scale, high resolving power, high brightness in a short time.
