Stereoscopic display

Abstract

The invention relates to a stereoscopic display. On the basis of an electric control varifocal lens technology, the distribution and fluctuation degree of the refractive index of a holographic polymer dispersed liquid crystal box is changed by responding to voltage applied between a linear transparent electrode and a transparent conductive film so as to achieve a lens effect on visible light in the control voltage direction. A period can be switched between a two-dimensional (2D) working mode and a three-dimensional (3D) working mode and dynamic tracking regulation can be carried out according to the position of a user. The stereoscopic display is compatible with the conventional liquid crystal panel manufacturing technology, and has simple process and low cost. An electric control naked eye three-dimensional imaging effect is achieved and the brightness of a system is not lost. A display placement state can be rapidly switched in the transverse direction, the longitudinal direction and multiple directions, and the stability of resolution and integrated color uniformity is ensured. A three-dimensional naked eye stereoscopic display system can dynamically regulate various parameters of an equivalent cylindrical lens according to the position of a viewer so as to ensure the optimal viewing effect.

Description

technical field [0001] The invention relates to a display, in particular to a stereoscopic display capable of realizing 2D-3D conversion and having a dynamic adjustment function. Background technique [0002] The distance between the human eyes in the horizontal direction is about 65mm, so when observing the same object, there will be two slightly different viewing angles. Due to optical projection, the image points with different distances from the observer fall on the corresponding retinas of the left and right eyes. At different positions, this horizontal disparity on the retina of both eyes is called binocular parallax, which forms stereoscopic vision in the human brain through the fusion of neural networks. [0003] At present, most stereoscopic display systems obtain stereoscopic vision based on the mechanism of binocular perception of stereoscopic information. Early stereoscopic displays all needed to wear specific eyes to watch. Although stereoscopic vision can be o...

AI Technical Summary

Problems solved by technology

Secondly, the microlens must be precisely matched and aligned with each column of pixels, and a small error will cause serious crosstalk between adjacent pixels, which has a great impact on the yield

The most important thing is that once the lens material is cured, its focal length is fixed and cannot be changed and adjusted, and the focusing function cannot be realized

Such a stereoscopic display cannot dynamically adjust the viewing angle, nor does it have a 2D-3D mode conversion function

The above-mentioned cost and functional problems inevitably weaken the advantages of lenticular stereoscopic displays
