Step S2: when the display display 3-D view that two-dimensional/three-dimensional switches, first electrode 310 and the second electrode 320 load specific voltage, formed to make liquid crystal layer 34 and to be arranged side by side along first direction and to take second direction as multiple second lens units 36 of length bearing of trend, and each second lens unit 36 is along the corresponding two row pixels 13 of first direction, with the right and left eyes making the light of the adjacent two row pixels 13 of display panel 10 enter beholder respectively after the second lens 36 of its correspondence reflect.Such as, the voltage that first electrode 310 loads is 0v, the voltage that 15 electrode strips 322 of the second lens unit 36 correspondence load is followed successively by 3v, 2.12v, 1.77v, 1.53v, 1.35v, 1.2v, 0.95v, 0v, 0.95v, 1.2v, 1.35v, 1.53v, 1.77v, 2.12v, 3v, the electric field that the first electrode 310 making the electrode strip 322 of the second lens unit 36 correspondence corresponding with the second lens unit 36 is formed is with the Central Symmetry of this second lens unit 36, thus deflect under the effect of the electric field that the liquid crystal molecule 340 in the liquid crystal layer 34 of this second lens unit 36 of formation is formed at the electrode strip 322 that the first electrode 310 of this second lens unit 36 correspondence is corresponding with this second lens unit 36, then zones of different is changed in this second lens unit 36 to the refractive index of light.
Please refer to Fig. 8, have more ground, specifically comprising the following steps during the display display two dimensional image that two-dimensional/three-dimensional of the present invention switches:
Step S11: human eye tracing module gathers position of human eye information, and this position of human eye information is sent to voltage-drop loading module.
Step S12: voltage-drop loading module loads should the voltage of position of human eye information on the first electrode 310 and the second electrode 320.
Step S13: the liquid crystal layer 34 of liquid crystal lens 30 is formed should multiple first lens units 35 of position of human eye information.
Step S14: the light folding that each row pixel 13 of display panel 10 sends converges in the outside of liquid crystal lens 30 and formed should the extraction regions C of position of human eye information after the first lens unit 35 of correspondence reflects.
More specifically, in above-mentioned display method, when display display 3-D view, each second lens unit 36 is along can the adjacent n row pixel of corresponding display panel 10 in second direction, adjacent n row pixel is respectively used to show the n width image with level visual difference, wherein n be 2 or be greater than 2 integer.
Fig. 9 is the light luminance simulation result schematic diagram of display when showing 3-D view and two dimensional image that two-dimensional/three-dimensional of the present invention switches.Please refer to Fig. 9, wherein, represent the brightness of 2D/3D switchable displays display two dimensional image in prior art with curve a in Fig. 9, the brightness at display two dimensional image of display that two-dimensional/three-dimensional of the present invention switches is represented with curve b, represent the brightness of the image of corresponding beholder's right eye in 3-D view with curve c, curve d represents the brightness of the image of corresponding beholder's left eye in 3-D view.When the display display two dimensional image that two-dimensional/three-dimensional of the present invention switches, the liquid crystal layer 34 of liquid crystal lens 30 forms multiple first lens unit 35, and multiple first lens unit 35 is along row pixel 13 one_to_one corresponding each in second direction and display panel 10, the light that on display panel 10, each row pixel 13 sends is after corresponding first lens unit 35 reflects, at formation extraction regions, the outside C of liquid crystal lens 30, the two dimensional image that beholder sees in the C of extraction regions has converged the light that the last each row pixel 13 of display panel 10 sends, therefore the brightness (shown in curve b) of the two dimensional image seen in the C of extraction regions of beholder is greater than the brightness (shown in curve a) of existing display display two dimensional image, therefore the display that two-dimensional/three-dimensional of the present invention switches has the effect of two dimensional image blast.In addition, the brightness of the two dimensional image after the blast that beholder sees is greater than beholder and watches brightness normally, therefore can by reducing the brightness of the backlight of the display that two-dimensional/three-dimensional switches, make beholder watch the two dimensional image of normal brightness at this extraction regions C, thus realize energy-conservation effect.
Can be found out by 3D simulation result: when the display display 3-D view that two-dimensional/three-dimensional switches, the brightness entering the left-eye image of beholder's left eye is high-high brightness, the brightness entering the eye image of beholder's left eye is minimum brightness, the brightness simultaneously entering the eye image of beholder's right eye is high-high brightness, the brightness entering the left-eye image of beholder's right eye is minimum brightness, therefore the display of two-dimensional/three-dimensional switching of the present invention is when showing 3-D view, effectively can reduce the signal cross-talk between left-eye image and eye image, beholder is made to see clearly 3-D view.
