The processing mode carried out as secondary image signal source such as an image signal source is handled again, when secondary image signal source
When needing to show 3D signals, the grating electrode 2121 of the 3D raster units 2 of controller driving crawl image-region, so that 3D light
Liquid crystal in grid unit 2, which is realized, stands, and realizes the function of grating, the image in region is shown in 3D effect；Work as secondary image
When signal source needs the 2D to show, 3D raster units 2 do not work, and realize that 2D is shown.
It is similar when a signal source needs 3D display, 2D-3D image pane of the signal source through image processing module
Formula modular converter is converted to 3D rendering signal；Believed by applying voltage to grating electrode 2121 in all 3D liquid crystal gratings units 2
Number, so as to realize the standing of liquid crystal in 3D liquid crystal gratings, realize the function of 3D gratings.Shown when needs carry out 2D to crawl image
When, controller cancels the voltage signal to the grating electrode 2121 of 3D liquid crystal gratings unit 2 in grabgraf region, removes 3D liquid crystal lights
Liquid crystal in grid unit 2 is stood, that is, removes the effect of 3D gratings.
The principle of other display combinations is similar with displaying principle described above.
When signal source is 3D rendering signal, it is necessary to, it is necessary to which 3D-2D image format conversion modules are entered when showing 2D forms
Row picture signal is changed, so as to realize that 2D is shown.When 2D is shown, the liquid crystal in 3D liquid crystal gratings is not stood, as common 2D
Display screen, the brightness of image is not interfered with.When crawl image needs to show 3D display, now secondary singal source is that 3D rendering is believed
Number, secondary singal source carries out image conversion by 2D-3D image format conversions module.
In a word, preferred embodiment of the present utility model is the foregoing is only, it is all according to present utility model application the scope of the claims institute
The equivalent changes and modifications of work, it should all belong to the covering scope of the utility model patent.
