Embodiment Construction

[0022] FIG. 4 is a cross-sectional view of a preferred two-dimensional liquid lens array 22 of the present invention. Similar to the traditional liquid single-lens system, a two-dimensional liquid lens array is formed in the composite cavity composed of the first transparent plate 9, the second transparent plate 11 and the mesh hole 19, and the first transparent plate 9 and the second transparent plate 11 are composed of a transparent plate Made of glass or transparent plate resin, the mesh hole 19 can be made of a metal conductor covering an insulating layer, such as indium steel covered with a layer of polyimide, or made of a resin material that wraps a conductive layer and an insulating layer in turn, and the conductive layer Indium tin oxide can be used, and polyimide is used for the insulating layer. The cavity contains an immiscible electrolyte solution 13 and an insulating solution 12, which have different optical refractive indices. The electrolyte solution 13 can be c...

Abstract

The present invention provides a three-dimensional display, which uses the electrically moistening function, according to the position of the object to be displayed, to change the focus of the two-dimensional liquid lens array in real time dynamically; realizes the definition maximization of the displayed central object or figure, or the concerned image area; improves the on-the-spot feeling of the three-dimensional image. The display is characterized in that a two-dimensional liquid lens array 22 is arrayed on a two-dimensional flat-panel display 5 in evenly to form a three-dimensional display. The two-dimensional liquid lens array and the two-dimensional flat-panel display are placed in parallel, and the focus of the two-dimensional liquid lens array is variable. The two-dimensional flat-panel display 5 can be any kind of flat-panel display. The two-dimensional liquid lens array 22 is formed by the array of a plurality of liquid single-lens, and the array method of the lens can be a square matrix, or a matrix whose odd line and whose even line are staggered, or a honeycomb shaped matrix. The preferred application case of the present invention has simple structure and low cost.

Description

technical field [0001] The invention relates to a three-dimensional display technology, in particular to a three-dimensional display capable of realizing different dynamic depths of field. Background technique [0002] The principle of image-integrated stereoscopic display was first proposed by Lippmann in 1908. Figure 1 shows the shooting and display principles of the image-integrated stereoscopic display technology. The shooting end includes a shooting lens array 2 and an image sensor 4 . The shooting lens array 2 focuses the image of the object 1 on the image sensor 4 to form a two-dimensional image composed of many independent shooting sub-images 3 . The display end is composed of a two-dimensional flat display 5 and a display lens array 7. The two-dimensional flat display 5 displays a two-dimensional image composed of display sub-images 6, and through the focal length of the display lens array 7, an image 8 of a three-dimensional object is reconstructed in space.
