Embodiment Construction

[0020] Figure 1 shows the schematic diagram of image integration stereo display.

[0021] Fig. 2 shows the schematic diagram of the variable focus lens three-dimensional display of the present invention, which includes a two-dimensional flat display 5 and a variable focus liquid lens array 11, and the two-dimensional flat display 5 can be a current various large-screen flat display (for example, liquid crystal display, liquid crystal display, etc. plasma display, rear projection, etc.), the first and second preferred embodiments of the variable-focus liquid lens array 11 are described in detail in FIGS. 3 and 4, respectively.

[0022] In the preferred embodiment shown in Figure 3, the first liquid lens unit 27 is a multi-layer sandwich structure, including: the uppermost front transparent substrate 29, such as thin flat glass, covered with the first hydrophobic Layer 12 is made of, for example, TEFLON AF1600. The first intermediate partition 14 of the liquid lens unit is made ...

Abstract

An image integrated solid display device uses dynamic adjustable-focus liquid lens array, wherein the lens array is composed of a multilayer sandwich liquid lens unit, the focus adjustment of the lens array is synchronized with the display frame speed of a two-dimension screen, to time-sharing realize different spatial solid images, use the vision holding effect of eye to improve the three-dimension depth feeding of solid image, and adjust the contact of two liquids in the liquid lens unit into a plane to switch between two-dimension and three-dimension display modes.

Description

technical field [0001] The invention relates to a three-dimensional stereoscopic display technology, in particular to an image-integrated stereoscopic display utilizing a dynamic variable-focus liquid lens array. Background technique [0002] At present, stereoscopic displays based on binocular parallax mainly use two-dimensional flat display devices plus lenticular lenses or parallax barriers to send different images to the left and right eyes respectively. There are differences in the images so that a three-dimensional stereoscopic image is perceived. The main problems of this type of stereoscopic display device are: the observer must be in a specific position to watch the stereoscopic image, the convergence point (convergence) of the observer's eyes and the adjustment angle (accommodation) of the observer's eyes do not coincide, and long-term viewing will cause visual fatigue and discomfort. . [0003] Image integration (integral imaging) stereoscopic display technology...
