Problems solved by technology

[0012] Holographic 3D technology and volumetric 3D display technology, compared with Barrier, LenticularLens and DirectionalBacklight 3D display technologies, each pixel or the image of each pixel is not on the same plane. 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 Compared with ordinary 2D display devices, stereoscopic three-dimensional display devices have a much more complex structure, and due to structural factors, they are larger in size and higher in cost, and they are not compatible with existing LCD panels, so the development and production costs higher

Embodiment 1

[0047] Such as Figure 2-4 As shown, the present embodiment provides a kind of 3D display device 50 based on electro-induced refractive index change, and the device 50 includes a two-dimensional liquid crystal panel display 51, and one is arranged on the front end of the display screen 51 (that is, the display screen 51 displays The front of the surface) is a plate-shaped transparent electro-optic crystal array 52. ​​The electro-optic crystal array 52 is composed of a plurality of electro-optic crystals 521 of the same shape and size. The shape of each electro-optic crystal 521 is a rectangular parallelepiped column, and the columnar The bottom surface is square, and the bottom surface 5211 of the columnar body is opposite to the display screen 51. The liquid crystal panel display screen 51 includes a plurality of square pixel points 511 of the same size, and the ground 5211 of the columnar body is the same size as the pixel point 511. Opposite to each pixel point 511, two pla...

Abstract

The invention provides a 3D display method based on electrically-induced refractive index change. The method is characterized in that the front end of a two-dimension display screen is provided with a flat-plate-shaped transparent electro-optical crystal array; the flat-plate-shaped transparent electro-optical crystal array is formed by square-column-shaped electro-optical crystals which are the same with pixel points of the two-dimension display screen in quantity; the cross section of each electro-optical crystal, which is parallel to the display screen, is the same as each pixel point of the two-dimension display screen in size; each electro-optical crystal directly faces to each two-dimension display screen pixel point; and a voltage corresponding to the depth of field of each pixel point directly facing the electro-optical crystal is applied to the electro-optical crystal through a control module. Images displayed through the 3D display method can be watched with naked eyes; resolution and brightness of the displayed three-dimensional images 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 stereoscopic display, and relates to a 3D 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 methods to b...
