Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0027] As shown in FIG. 1 , the naked-eye visible three-dimensional image liquid crystal grating time-sharing display device includes a display, a PC host 1 provided with a drawing card, an image screen 2 and a grating screen 3 . The image screen 2 and the grating screen 3 are respectively connected with the drawing card on the PC host 1 . The drawing card is a general-purpose computer graphics processing card, which can synchronously display two frames of graphics on the raster screen and the image screen. The drawing card can obtain the three-dimensional model data including the three-dimensional coordinates of all points representing the surface shape of the object and the three-dimensional image of its color and gray scale through a three-dimensional object scanning ...

Abstract

The invention relates to the stereo image liquid crystal grating time-sharing display device which is visual to bare eyes. The invention comprises a display and a PC host computer which is provided with a drawing card. The display comprises an image screen and a grating screen. The image screen and the grating screen are all connected with the drawing card. An angle a is formed between the X axis of the image screen and the X axis of the grating screen, and the value range of the angle a is between 0 degree and 90 degrees. The invention can satisfy bare eyes to watch the stereo images, simultaneously, the invention solves the defect that serious light interference phenomenon caused by the point-pixel distance coupling of the image screen and the grating screen in the prior art. The display can normally word and better effect of watching stereo images using bare eyes can be guaranteed. The applied range of the device is wide; thereby the device can be suitable to watch 2D/3D images.

Description

technical field [0001] The invention relates to the technical field of autostereoscopic image display (Autostereoscopic Display), in particular to a liquid crystal grating time-sharing display device for naked-eye visible stereoscopic images. Background technique [0002] At present, in the technical field of autostereoscopic image display, a method called naked-eye visible stereoscopic image display method has appeared. The so-called naked-eye stereoscopic image display method means that stereoscopic images can be viewed without wearing special tools (such as special glasses and a helmet). The basic principle of the naked-eye stereoscopic image display method is to use a special picture, on which all odd-numbered lines are used to represent a right-eye image, and all even-numbered lines are used to represent a left-eye image , through the grating at a certain set position, the right eye can just see all the odd-numbered rows and columns on the picture, and the left eye can...
