Figure, and so on, until first row display unit terminates.
Wherein, the value that the value of N1 is preferably 5, N2 is preferably 14.That is, the first row in the corresponding upper left corner, the 1st arrives
5th row display unit is used to show the first view, and the 6 to 19th row display unit is used to show the second view, and the 20 to 33rd row is shown
Show unit be used for show the first view.That is, initial 5 row display unit is used to show the first view, ensuing 14 row is shown
Unit shows the second view for display unit, and 14 row display units next are used to show the first view, next
14 row display units be used to show the second view, 14 row display units next are used to show the first view, according to this class
The row are pushed into terminate.
For the secondary series display unit since the upper left corner, the N2 display unit of order down is used to show that first regards
Figure, then the N2 display unit of order down are used to show the second view, and so on, until secondary series display unit terminates.
That is, for the secondary series display unit since the upper left corner, the 1st row to the 14th row display unit is used to show first
View, the 15 to 28th row display unit are used to show the second view, and the 29 to 42nd row display unit is used to show the first view.
That is, initial 14 row display unit is used to show the first view, and ensuing 14 row display unit is used to show the second view, then connects
The 14 row display units to get off are used to show the first view, and 14 row display units next are used to show the second view, then
Ensuing 14 row display unit is used to show the first view, and so on terminates to the row.
For the 3rd row display unit since the upper left corner, preceding N3 display unit is used to show the second view, order
N2 display unit down is used to show the first view；For the other display unit in addition to preceding N2+N3 display unit,
The N2 display unit of order down is used to show that the second view, then the N2 display unit of order down are used to show that first regards
Figure, and so on, until the 3rd row display unit terminates.
Wherein, the value of N3 is preferably 9.3rd row in the corresponding upper left corner, the 1st to the 9th row display unit are used to show

Next 14 row display units are used to show the second view, and 14 row display units next are used to show that first regards
Figure, 14 row display units next are used to show the second view, and so on terminate to the row.
Specific row's figure mode of the first row since the upper left corner, secondary series and the 3rd row display unit described in detail above,
The display of view can be carried out according to following row's figure modes for other row display units in addition to above-mentioned three arrange：3M-2 row are aobvious
Show that the view display mode of unit is consistent with first row display unit；The view display mode and second of 3M-1 row display units
Row display unit is consistent；The view display mode of 3M row display units is consistent with the 3rd row display unit；Wherein, M be more than
Positive integer equal to 2.
That is, for the 4th row, the 7th row, the tenth row, the 13rd row ... for the display unit waited, it is same that it arranges figure mode
First row display unit is consistent；For the 5th row, the 8th row, the 11st row, the 14th row ... for the display unit waited, it is arranged
Figure mode is consistent with secondary series display unit；For the 6th row, the 9th row, the 12nd row, the 15th row ... the display unit waited
For, it is consistent with the 3rd row display unit that it arranges figure mode.
It should be noted that in order to further reduce 3D crosstalk phenomenons, for for showing that the first view and second regards
Two adjacent display cells of figure, in embodiments of the present invention as shown in figure 5, in two adjacent display cells it is at least one with
Low-light level is shown.Why at least one in adjacent display unit is shown with low-light level, be because two adjacent
Display unit just at the intermediate region of each grating, i.e., two adjacent display units can be across the left and right portion of grating
Point, it is the position for increasing 3D crosstalks, it is shown with the brightness less than normal display brightness, can significantly weakens 3D strings
Disturb, lift 3D display effect.Referring to Fig. 5, the 5th row display unit is used to showing the first view in first row, the 6th row in first row
Display unit is used to show the second view, the two display units are adjacent display unit, at least one of which can with less than
The brightness of normal display brightness is shown.For the 19th row display unit and the 20th row display unit in first row, and two
A adjacent display unit, same at least one of which can be shown with the brightness less than normal display brightness.For first
Adjacent display unit in the adjacent display unit of other in row or other row, and so on, same at least one of which can be with
Brightness less than normal display brightness is shown.
Wherein, the brightness ratio of at least one display unit in two adjacent display cells is normal display brightness
0% to 80%.Preferably, the brightness ratio of at least one display unit in two adjacent display cells is normal display brightness
50%.
Display device provided in an embodiment of the present invention, by using inclined Grating Design, and uses multiple display units
In independent the first view of display of the first display unit, individually display second regards the second display unit in multiple display units
Figure, therefore effectively improve small-medium size and show experience effect of the product when transverse screen watches bore hole 3D, considerably reduce
Crossfire value and moire fringes.
It should be noted that 3 d display device provided in an embodiment of the present invention can be any tools such as mobile phone, tablet computer
There are the mobile product or component of display function, the embodiment of the present invention limits this without specific.Meanwhile the embodiment of the present invention carries
The 3 d display device of confession can also carry human eye tracer technique and scan picture technology, further to optimize bore hole 3D
Display effect.
One of ordinary skill in the art will appreciate that hardware can be passed through by realizing all or part of step of above-described embodiment
To complete, relevant hardware can also be instructed to complete by program, the program can be stored in a kind of computer-readable
In storage medium, storage medium mentioned above can be read-only storage, disk or CD etc..
