3D (Three Dimensional) display equipment and method based on electric-induced refractive index conversion

Abstract

The invention provides 3D (Three Dimensional) display equipment based on electric-induced refractive index conversion. The equipment comprises a two-dimensional plane display screen and a flat-plate-shaped transparent electro-optical crystal array arranged on the front end of the display screen, wherein the electro-optical crystal array is formed by square-column-shaped electro-optical crystals which are the same as display screen pixel points in quantity; a section of each electro-optical crystal, which is parallel to the display screen, is the same as each display screen pixel point in size; each electro-optical crystal is over against each display screen pixel point; the 3D display equipment further comprises a transparent electrode for applying voltage to each electro-optical crystal and a control module which is electrically connected with the electrode; and the control module is used for controlling the electrode to apply voltage which corresponds to field depth of the pixel points over against the electro-optical crystals to the electro-optical crystals. An image displayed by the 3D display equipment disclosed by the invention can be watched by naked eyes; the resolution ratio and the brightness of a displayed three-dimensional image are not changed; and the displayed three-dimensional image has the real physical field depth.

Description

【Technical field】 [0001] The invention belongs to the technical field of three-dimensional display, and relates to a 3D display device and a display method based on electro-induced refractive index change. 【Background technique】 [0002] 3D, also known as three-dimensional stereo or three-dimensional, 3D imaging technology is different from two-dimensional plane imaging technology, compressing three-dimensional image information into a two-dimensional plane will inevitably distort the image, and it is impossible to prepare each pixel in the reaction image The real space position, the three-dimensional image displayed on the two-dimensional plane is expressed by the light and shade of the color, the size of the object and other information. Judging the distance of each pixel in the two-dimensional plane from the human eye, rather than the real physical depth of field. [0003] The difference between three-dimensional display and two-dimensional display is to use various meth...

Problems solved by technology

[0012] Holographic 3D technology and volumetric 3D display technology Compared with Barrier, Lenticular Lens technology, and Directional Backlight 3D display technology, each pixel or the image of each pixel is not on the same plane In addition, it has a real depth of field, so when watching 3D images, users will not have side effects such as dizziness, headache, and eye fatigue, and the resolution and brightness of the screen will not be reduced, and there is not much restriction on the vision and angle of viewing 3D images , but because the structure of the stereoscopic three-dimensional display device is much more complicated than that of the ordinary 2D display device, and due to the structural factors, the volume is larger, the cost is higher, and it is not compatible with the existing LCD panel, so the development more expensive to produce
