Stereopicture display

Abstract

The invention provides a stereopicture display, comprising a display component and an actuating component, wherein the display component comprises a backlight module, a liquid crystal display panel and a cylinder lens raster which are orderly arrayed from inside to outside, wherein the backlight module is used for transmitting a light source to the liquid crystal display panel; the liquid crystal display panel is used for displaying pictures; the cylinder lens raster is arranged between the liquid crystal display panel and a viewer; the cylinder lens raster comprises a support part and an optical part which is fixed on the support part; the actuating component comprises at least two coils having the same magnetic field and a plurality of first magnets; the coils are respectively arranged on two opposite sides of the support part in parallel and are electrically connected with a power source; the first magnets are respectively fixed on two opposite sides of the support part and respectively adjacent to the coils; polarities of opposite poles of every two first magnets are opposite; the coils are controlled to be in mutual attraction or mutual repulsion with the first magnets by controlling the current direction and the current frequency of the coils so that the cylinder lens raster can reciprocate in the direction parallel to the liquid crystal display panel.

Description

technical field [0001] The invention relates to the field of image display, in particular to a stereoscopic image display. Background technique [0002] The current stereoscopic movies and stereoscopic images require the help of stereoscopic glasses so that the left eye of the viewer can only see the image of the left eye, and the right eye can only see the image of the right eye. Those who produce stereoscopic sensation. However, this method requires the help of external tools, such as glasses made of polarizers, which is troublesome when viewing stereoscopic images. Therefore, it has become an important research and development topic for those skilled in the art to see the stereoscopic effect with naked eyes. [0003] A kind of existing technology of viewing stereoscopic images directly with naked eyes is to adopt a liquid crystal display screen and a stereoscopic grating. , using the refraction and focusing effects of the three-dimensional grating so that the left and ...

Problems solved by technology

However, this method requires that the synthesized stereoscopic image is composed of stripes parallel to the axis of the lenticular grating, so that the image on each stripe can be emitted to the left and right eyes, and each picture in the stereoscopic image is required to be at the same grating pitch. The lower and equal intervals are arranged sequentially, so an LCD display with a specific display effect can meet the above requirements, making ordinary LCDs unable to achieve stereoscopic display
