Embodiment
Fig. 1 is the diagrammatic cross-section of the switchable stereoscopic display of one embodiment of the invention.Please refer to Fig. 1, the switchable stereoscopic display 100 of present embodiment comprises switchable type parallax resistance barrier element 110 and a display panel 120, and switchable type parallax resistance barrier element 110 is disposed at display panel 120 tops.Switchable type parallax resistance barrier element 110 comprises a first substrate S1, a second substrate S2, an insulation course 112, a common electrode 114 and a light valve layer 116.First substrate S1 has a touch control line 118, second substrate S2 is disposed between first substrate S1 and the display panel 120, and second substrate S2 has a plurality of control electrodes 119, and touch control line 118 and control electrode 119 are between first substrate S1 and second substrate S2.In addition, it is upper with covering touch control line 118 that insulation course 112 is disposed at first substrate S1, and common electrode 114 is disposed on the insulation course 112, and light valve layer 116 is disposed between common electrode 114 and the control electrode 119.In other words, common electrode 114 is between insulation course 112 and light valve layer 116.
In the present embodiment, display panel 120 can be the two-d display panel of any kenel, such as display panels, organic electric-excitation luminescent displaying panel, Plasmia indicating panel, electrophoretic display panel etc.Usually, the display panels suitable backlight of need arranging in pairs or groups can be reached good demonstration usefulness.
Can know from Fig. 1 and to learn that insulation course 112 is between common electrode 114 and touch control line 118, to guarantee unusual short circuit phenomenon can not occur between common electrode 114 and the touch control line 118.In addition, can in regional area, change according to the electric field between common electrode 114 and the control electrode 119 its light transmittance (transmittance) at the light valve layer 116 between common electrode 114 and the control electrode 119.In the present embodiment, light valve layer 116 for example is a liquid crystal layer, and control electrode 119 for example is a plurality of strip shaped electric poles parallel to each other, control electrode 119 is in order to defining a plurality of slit S parallel to each other, and the width of this slit S and spacing can according to the pixel on the display panel 120 apart from and do suitable change.
When common electrode 114 is coupled to a common electric voltage (for example being coupled to DC voltage or ground connection), and each control electrode 119 connects when being coupled to a control signal, light transmittance at the light valve layer 116 above the control electrode 119 can significantly reduce (penetrance is near 0) because of the voltage difference between common electrode 114 and the control electrode 119, at this moment, display panel 120 shown images only can be watched by the user by slit S, and the image that the user watches is stereopsis.For example, light valve layer 116 can be selected Normally white liquid crystal material, (meaning namely when switchable type parallax resistance barrier element 110 is not unlocked, do not have voltage difference between common electrode 114 and the control electrode 119) time, display panel 120 shown image energies still pass smoothly light valve layer 116 and reach the purpose that bidimensional image shows.Obvious, when selecting Normally white liquid crystal material, light valve layer 116 can reach the purpose of power saving.But the present invention is not limited with Normally white liquid crystal material, decides on the design requirement of product.
As can be seen from Figure 1, touch control line 118, insulation course 112 and common electrode 114 all are to be made on the inside surface of first substrate S1,119 of control electrodes are to be made on the inside surface of second substrate S2, and light valve layer 116 (for example being liquid crystal layer) is then inserted therebetween after first substrate S1 and second substrate S2 group is vertical.Hold above-mentioned, has the switchable type parallax resistance barrier element 110 of touch control line 118 on making, only need use two plate bases (being first substrate S1 and second substrate S2), so the integral thickness of switchable type parallax resistance barrier element 110 can further reduce, and switchable type parallax resistance barrier element 110 also can further be lowered on cost of manufacture.
