That is, similarly to the prior art, the liquid crystal layer 13 that the liquid crystal lens 1 of the present embodiment also comprises first substrate 11, second substrate 12 and is clipped between substrate, and one of them substrate has strip shaped electric poles 111, and another substrate can have plate electrode 121 (or also can be strip shaped electric poles), thus this part forms electric field, drive Formation of liquid crystals liquid crystal lens 1.Wherein, concrete, can be that each strip shaped electric poles 111 forms a lens unit, or, also by controlling strip shaped electric poles 111 voltage, make multiple strip shaped electric poles 111 form a lens unit, because the concrete mode forming lens is known, therefore be not described in detail at this.
In the present embodiment, be positioned on first substrate 11 with strip shaped electric poles 111, plate electrode 121 is positioned on second substrate 12 for example is described.But should be appreciated that if strip shaped electric poles 111 is positioned on second substrate 12, and plate electrode 121 to be positioned at first substrate 11 is also feasible.
When the present embodiment is located at display panel 4 light emission side when liquid crystal lens 1, sub-pixel 41 orientation of the relative display panel of strip shaped electric poles 111 is obliquely installed.
That is, be different from prior art, when the liquid crystal lens 1 of the present embodiment is located at display panel 4 light emission side, strip shaped electric poles 111 is not the direction of the row or column of the sub-pixel 41 being parallel to display panel, but have certain angle with the direction of the row or column of sub-pixel 41, thus the level of liquid crystal lens 1 and vertical direction can segmenting pixels.
Wherein, in display panel, each sub-pixel 41 lines up array, and namely they are arranged with column direction in the row direction, therefore the direction of this row or column is sub-pixel 41 orientation.
Preferably, the length direction of strip shaped electric poles 111 is parallel with a cornerwise direction of the sub-pixel 41 of display panel.
That is, as shown in Figure 3, Figure 4, first calculate the angle α in the direction of the diagonal line of the sub-pixel 41 of display panel and the row of sub-pixel 41, then the length direction of strip shaped electric poles 111 is set to α identical with the angle β in the direction of the row of sub-pixel 41.
For the full resolution mobile phone display screen of 5.5 cun, the length of its sub-pixel 41 is 63 μm, wide is 21 μm, the angle that can be calculated the direction of the diagonal line of sub-pixel 41 and the row of sub-pixel 41 is 71.57 degree, then the angle in the direction of the length direction of the strip shaped electric poles 111 of liquid crystal lens 1 and the row of sub-pixel 41 is also set to 71.57 degree.
This is because according to above design, in each lens unit of liquid crystal lens 1, liquid crystal molecule can be arranged according to the direction of strip shaped electric poles 111 length of liquid crystal lens 1, and liquid crystal molecule can have deviation effect to the polarized light being parallel to its long axis direction, light after deviation can be divided into line direction by the mode of Orthogonal Decomposition with column direction, each like this liquid crystal molecule in the row direction can light splitting with column direction, namely each lens unit in the row direction can light splitting with column direction, thus realize horizontal screen, perpendicular screen upset all can present clearly bore hole 3D rendering when switching.
Preferably, the width of strip shaped electric poles 111 is 5-20 μm, and the spacing of adjacent strip shaped electric poles 111 is 5-50 μm.
Find through research, the width of above strip shaped electric poles 111 and the spacing range of strip shaped electric poles 111 can meet the needs of most of display device.For the full resolution mobile phone display screen of 5.5 cun, its 4 sub-pixels 41 are a lens unit pitch L, then a lens unit pitch L is 79.67 microns, and corresponding 7 strip shaped electric poles 111 of each lens unit, the width of strip shaped electric poles 111 and spacing are 5.69 microns.
Below the working method of above liquid crystal lens 1 is described in more detail.
When needs horizontal screen viewing bore hole stereoscopically displaying images, as shown in Figure 5, first the stereoscopically displaying images of line of input arrangement, wherein for corresponding 4 sub-pixels 41 (such as marking the sub-pixel 41 of A1, A2, A3, A4) of a lens unit, so just need the stereoscopically displaying images of 4 viewpoints, after lens unit light splitting, obtain 4 interval one-view image, then enter the right and left eyes of people respectively, after brain merges, produce stereoscopically displaying images.
When needs perpendicular screen viewing bore hole stereoscopically displaying images, as shown in Figure 6, first the stereoscopically displaying images of input perpendicular screen direction arrangement, corresponding 4 sub-pixels 41 of lens unit, so just need the stereoscopically displaying images of 4 viewpoints, after the light splitting of liquid crystal lens unit, obtain 4 interval one-view image, entering the right and left eyes of people successively respectively, after brain merges, produce stereoscopically displaying images.
Preferably, the inner side of first substrate 11 and second substrate 12 is equipped with alignment film; The frictional direction a of the alignment film 112 inside first substrate is parallel with the frictional direction b of the alignment film 122 inside second substrate and contrary.
That is, as shown in Figure 3, the frictional direction a of the alignment film 112 inside first substrate is contrary with the frictional direction b of the alignment film 122 inside second substrate.
Preferably, the angle between the frictional direction of alignment film and the length direction of strip shaped electric poles 111 is 0-30 degree.Preferred, the angle between the frictional direction of alignment film and the length direction of strip shaped electric poles 111 is 0 degree.
That is, the frictional direction of alignment film is parallel with the direction of strip shaped electric poles 111.
Preferably, display panel 4 light emission side is provided with polaroid 42, and the frictional direction of alignment film is parallel with the direction that thoroughly shakes of the polaroid 42 of display panel.
This is because, in the 3D conceptual design of reality, when 3D crossfire value reduces, moire fringes is corresponding increase, two parameters are oppositely impacts, if the frictional direction of the alignment film inside first substrate 112 is contrary with the frictional direction of the alignment film 122 inside second substrate, and the frictional direction of alignment film is parallel with the direction of strip shaped electric poles 111, horizontal screen viewing and perpendicular problem of shielding 3D crosstalk and the moire fringes watched can be solved like this, the balance of both realizations, makes horizontal/vertical screen all can present bore hole stereo-picture.
Obviously, the optimum configurations of above-described embodiment also can carry out many changes; Such as: the angle between the frictional direction of alignment film and the length direction of strip shaped electric poles 111 is 15 degree or 20 degree etc., or the width of strip shaped electric poles is respectively 5,8,10,20 μm etc., the spacing of adjacent strip shaped electric poles should be 5,9,30,50 μm etc. mutually, also can realize horizontal/vertical screen completely and present bore hole stereo-picture.
