Described company looks three-dimensional and looks around three-dimensional time-division implementation method, it is characterized in that:

When the quantity of same place was N, wanting the arranged picture number on the display was N times that the plane shows, under the certain condition of display surface resolution, sharpness drops to the 1/N of plane picture; N same place, form N viewpoint, because pixel and slit grating all have certain width, each pilot will form the vision area of certain width, when the quantity of same place reaches 6-9, the vision area that a plurality of viewpoints form is continuous, the requirement of the solid that satisfied company looks and looks around, but the sharpness of image drops to the 1/6-1/9 that original plane shows.

Parallax baffle preferably adopts refreshing frequency to reach the above liquid crystal material of 100Hz, be used for moving image and need take 25Hz, when same place quantity is 8, preferred employing 4 timesharing show, in each timesharing, flat-panel monitor is only required and is shown that 2 same places, its sharpness can accomplish consistent with left and right sides image substantially fully, reach the degree of Standard Definition Television, function is looked and looked around in the company of realization; When the quantity of same place is 9, adopt 3 timesharing, in each timesharing, the quantity of same place only requires and shows 3 that sharpness can meet the demands substantially.

When solid is looked by the company of realization, what level change viewpoint was seen is the stereo-picture of the same shape of same object, though the quantity of same place has 6-9, but have only two kinds of same places, it is left and right sides same place, all left same places its bright signal except that the coordinate difference is the same, all right same places its bright signal except that the coordinate difference is the same, image shows that the source only needs a stereoscopic image frame, be left same place picture frame and right same place picture frame, do translation at horizontal level by the coordinate of same place and form multiple image, obtaining by the pair of parallel camera of image source obtained.When the timesharing number is twice, by two groups of grating Alternation Display; When the timesharing number is 3 times, by 3 groups of grating Alternation Display, when the timesharing number is 4 times, by 4 groups of grating Alternation Display.

Look solid for the company of one 3 timesharing, its image display periods is:

1), the 1st timesharing, the 1st group of horizontal narrow slit grating state:

(1), left same place picture frame,

(2), right same place picture frame,

(3), left same place picture frame,

2), the 2nd timesharing, the 2nd group of horizontal narrow slit grating state:

(1), right same place picture frame,

(2), left same place picture frame,

(3), right same place picture frame,

3), the 3rd timesharing, the 3rd group of horizontal narrow slit grating state:

(1), left same place picture frame,

(2), right same place picture frame,

(3), left same place picture frame,

When the high definition solid is looked by the company of realization, left same place high-definition image frame and right same place high-definition image frame are arranged; Left side same place high-definition image frame is divided into strange SD picture frame in a left side and left even SD picture frame, right same place high-definition image frame is divided into right strange SD picture frame and right even SD picture frame, and when adopting timesharing to show, actual timesharing number reduces half, ghost image point will increase with single view, but sharpness improves; Along with the raising of refreshing frequency, the no ghost image that can solve fully under the high definition condition is even looked stereo display; When realizing that the rear-projection high definition is even looked solid, can adopt two or more projectors to solve the not enough problem of refreshing frequencys, thereby the no ghost image that reaches under the high definition condition is looked around stereo display.Concerning solid was looked by the company of one 4 timesharing, embodiment of its image display periods was:

1), the 1st group of horizontal narrow slit grating state:

(1), the 1st timesharing: the strange picture frame of left same place, the strange picture frame of right same place;

(2), the 2nd timesharing: left same place bigraph picture frame, right same place bigraph picture frame;

2), the 2nd group of horizontal narrow slit grating state

(3), the 3rd timesharing: the strange picture frame of left same place, the strange picture frame of right same place;

(4), the 4th timesharing: left same place bigraph picture frame, right same place bigraph picture frame.

When realizing looking around solid, what level change viewpoint was seen is the difform stereo-picture of same object, what same places are arranged, what picture frames are then arranged, the obtaining to take by many parallel cameras of same place obtained, also the parallax prediction can be done in a pair of stereographic map source of pair of parallel camera acquisition, form a series of disparity map picture frames, the described solid of looking around is than the demonstration of even looking the approaching more natural true three-dimension object of stereo display.When the timesharing number is twice, by two groups of grating Alternation Display; When the timesharing number is 3 times, by 3 groups of grating Alternation Display, when the timesharing number is 4 times, by 4 groups of grating Alternation Display.

Three-dimensional for looking around of one 3 timesharing 9 two field pictures, its image display periods is:

1), the 1st timesharing, the 1st group of horizontal narrow slit grating state:

(1), the 1st group of same place picture frame;

(2), the 2nd group of same place picture frame;

(3), the 3rd group of same place picture frame;

2), the 2nd timesharing, the 2nd group of horizontal narrow slit grating state:

(1), the 4th group of same place picture frame;

(2), the 5th group of same place picture frame;

(3), the 6th group of same place picture frame;

3), the 3rd timesharing, the 3rd group of horizontal narrow slit grating state:

(1), the 7th group of same place picture frame;

(2), the 8th group of same place picture frame;

(3), the 9th group of same place picture frame.

When realizing looking around the high definition solid, each same place high-definition image frame is divided into strange SD picture frame and even SD picture frame, show at twice, can reach the effect that high definition shows like this, be subjected to the restriction of display refreshing frequency, when realizing looking around the high definition solid, the quantity of frame of the same name reduces half, ghost image point will increase with single view, but sharpness improves; Along with the raising of refreshing frequency, the no ghost image that can solve fully under the high definition condition is looked around stereo display; When realizing that the rear-projection high definition is even looked solid, can adopt two or more projectors to solve the not enough problem of refreshing frequencys, thereby the no ghost image that reaches under the high definition condition is looked around stereo display.When the timesharing number was 4 times, by 2 groups of grating Alternation Display, for the high definition of looking around of one 4 timesharing, embodiment of its image display periods was:

1), the 1st group of horizontal narrow slit grating state:

(1), the 1st timesharing: the 1st group of same place left side picture frame, the 2nd group of same place left side picture frame;

(2), the 2nd timesharing: the 1st group of right picture frame of same place, the 2nd group of right picture frame of same place;

2), the 2nd group of horizontal narrow slit grating state:

(1), the 3rd timesharing: the 3rd group of same place left side picture frame, the 4th group of same place left side picture frame;

(2), the 4th timesharing: the 3rd group of right picture frame of same place, the 4th group of right picture frame of same place.

A described same place picture frame is the picture frame that a same place of different pixels is formed in the piece image, described strange SD picture frame and even SD picture frame and the contrast of described high-definition image frame, and just horizontal definition has reduced half, and vertically clearly constant.

Because the image demonstration is to scan demonstration from top to bottom, in the one secondary display frame, what top and the bottom showed is not a two field picture, realize to connect and to look and when looking around solid, zone of transition at the slit grating transition status, must make the slit grating state corresponding, to avoid occurring cross-interference issue slit grating and each two field picture segmentation with two field picture.

When the company of realization looks three-dimensional and looks around solid, each same place picture frame is different relative translation positions with the slit grating of different timesharing, the present invention also can immobilize slit grating, employing divides constantly in difference, and the mode of translation same place picture frame realizes the change with the slit grating relative position.

Three-dimensional time-division implementation method is looked around in described pitching, it is characterized in that:

When realizing that solid is looked around in pitching, can be from level and vertical both direction change viewpoint, what see is the difform stereo-picture of same object, looks around the requirement of solid for reaching pitching, the quantity of same place can be 16 or 18 or 24 etc.When the quantity of same place was 24, the same place quantity of horizontal direction can be 6, showed that at twice horizontal definition drops to 1/3, and vertical direction same place quantity is 4, showed that at twice vertical definition drops to 1/2.This moment, parallax baffle was the complex light sieve structure, during 24 same places, took by 24 matrix camera and to obtain 24 same places, 6 cameras of horizontal direction wherein, 4 cameras of vertical direction.This moment, its image display periods was by 4 groups of grating Alternation Display:

1), the 1st group of horizontal narrow slit grating and the 1st group of light sieve state that the vertical slits grating is formed:

(1), Aa group same place picture frame;

(2), Ab group same place picture frame;

(3), Ba group same place picture frame;

(4), Bb group same place picture frame;

(5), Ca group same place picture frame;

(6), Cb group same place picture frame;

2), the 2nd group of horizontal narrow slit grating and the 1st group of light sieve state that the vertical slits grating is formed:

(1), Da group same place picture frame;

(2), Db group same place picture frame;

(3), Ea group same place picture frame;

(4), Eb group same place picture frame;

(5), Fa group same place picture frame;

(6), Fb group same place picture frame;

3), the 1st group of horizontal narrow slit grating and the 2nd group of light sieve state that the vertical slits grating is formed:

(1), Ac group same place picture frame;

(2), Ad group same place picture frame;

(3), Bc group same place picture frame;

(4), Bd group same place picture frame;

(5), Cc group same place picture frame;

(6), Cd group same place picture frame;

4), the 2nd group of horizontal narrow slit grating and the 2nd group of light sieve state that the vertical slits grating is formed:

(1), Dc group same place picture frame;

(2), Dd group same place picture frame;

(3), Ec group same place picture frame;

(4), Ed group same place picture frame;

(5), Fc group same place picture frame;

(6), Fd group same place picture frame.

Because the image demonstration is to scan demonstration from top to bottom, in the one secondary display frame, what top and the bottom showed is not a two field picture, when realizing that solid is looked around in pitching, zone of transition at slit light sieve transition status, slit light sieve and each two field picture segmentation must be made that slit light sieve state is corresponding with two field picture, to avoid occurring cross-interference issue; Along with the raising of display refreshing frequency, be expected to improve the sharpness that stereo display is looked around in pitching, when realizing that solid is looked around in the rear-projection pitching, can improve the sharpness that stereo display is looked around in pitching by the quantity that increases projector.

The feature of described parallax baffle is:

Its 1st adjacent orthogonal oriented layer 1, tft layer 2, liquid crystal shutter layer 3, common electrode layer 4 and the 2nd adjacent orthogonal oriented layer 5 and display screen 6 are formed; Polarization direction between the adjacent block of described the 1st adjacent orthogonal oriented layer 1 and described the 2nd adjacent orthogonal oriented layer 5 is mutually orthogonal, and the polarization direction of the two corresponding blocks is also mutually orthogonal.By reversing of control liquid crystal, realize logical retaining control to each pixel light transmission.When realizing that the plane shows, for all passing through, no parallax is blocked; When stereo display is looked by the company of realization, form the slit grating of horizontal direction, divide constantly, there is certain displacement in the horizontal direction in the slit grating of timesharing each time; When realizing looking around stereo display, form the slit grating of horizontal direction, divide constantly, there is certain displacement in the horizontal direction in the slit grating of timesharing each time, each slit grating state that divides constantly, corresponding different picture frames; When realizing that stereo display is looked around in pitching, form the light sieve that horizontal narrow slit alternately and vertical slits grating are formed, divide constantly, there is certain displacement in the slit grating of timesharing each time with vertical direction in the horizontal direction, the each state of light sieve constantly, corresponding different picture frames of dividing; Like this by to liquid crystal parallax plate washer ground control, just realized plane picture, connected the parallax stereogram picture, looked around the compatibility demonstration that stereo-picture is looked around in stereo-picture and pitching; The present invention can realize the logical retaining control of the sight line of each pixel, thereby in same display frame, the subregion can realize that the plane shows, stereo display can the company of realization be looked in the subregion, stereo display can be realized looking around in the subregion, the subregion can realize that pitching looks around the compatibility of stereo-picture and show, thereby has realized plane picture, connects the parallax stereogram picture, looks around the Combination demonstration that stereo-picture is looked around in stereo-picture and pitching.

Because the brightness of light per pass oriented layer will reduce, and when parallax baffle is preposition, utilize the exiting surface oriented layer of display panels, cancel the 1st adjacent orthogonal oriented layer, form adjacent orthogonal orientation display screen, thereby guarantee that brightness reaches the requirement of demonstration; When parallax baffle is rearmounted, utilize the incidence surface oriented layer of display panels, cancel the 2nd adjacent orthogonal oriented layer, form adjacent orthogonal orientation display screen, thereby guarantee that brightness reaches the requirement of demonstration.Preposition LCD LCD, PDP plasma display, FED Field Emission Display, OLED organic electroluminescence optical display unit, CRT ultrathin display and the rear-projection display device etc. of being widely used in of described parallax baffle; Described parallax baffle postposition can only be used for LCD TV and rear-projection TV, but helps adopting the measure that highlights.
