2.In this embodiment, electric field receiving layer is mainly comprised of two parts, be electric field receiving layer 341 and electric field receiving layer 342, electric field receiving layer is that composition forms on insulation course 343, also be, electric field receiving layer 341 and electric field receiving layer 342 are that composition forms at grade substantially, particularly, as shown in Figure 2, electric field receiving layer 341 is the electrode of four strips, its correspondence is arranged on the border area of the 2nd ITO conductive glass layer 330, electric field receiving layer 342 correspondences are arranged on the middle section of the 2nd ITO conductive glass layer 330, article four, in the region that the electrode 341 of strip surrounds, form electric field receiving layer 342.Electric field transmitted layer 344, electric field receiving layer 341 and 342 can choice for use ITO electrode material.
When pointing or hand enters the top of display device 30, will inevitably change the formed electric field of electric field transmitted layer 344, by electric field receiving layer, receive electric field signal with the potential change of judgement electric field, thereby can further calculate the variations such as finger Huo Shou position, moving direction, gesture.It will be appreciated that, 3D interaction-electrode 340 also needs to be used in conjunction with other interaction controlling portion parts etc. and controls function with the complete 3D of realization gesture interaction, at this, omits the specific descriptions to other components.Further it will be appreciated that, the setting of electric field transmitted layer 344, electric field receiving layer 341 and 342 concrete structures and plane composition pattern, the pattern and the structure that are formed on the 3D interaction-electrode in the 2nd ITO electro-conductive glass aspect 334 are not limited to the pattern shown in Fig. 3 and Fig. 5 and structure, it can, according to specific implementation principle and concrete needs, carry out corresponding specific design.
Continue to consult Fig. 2, layer of polarizer 390 is placed in the top of this 3D grating, and it can be used to form the upper layer of polarizer of parallax barrier.Preferably, for the sensitivity that guarantees to touch, for example, the electric capacity of finger is easily added on self-capacitance, and the thickness of layer of polarizer 390 can be arranged in the scope of 0.1mm to 3mm.
Therefore, when 3D grating is placed on two dimensional image display module 100, formed the stereoscopic display device of embodiment as shown in Figure 2, owing to being integrated with 3D interaction-electrode 340, the simultaneously all right compatible 3D gesture interaction function of this stereoscopic display device, can greatly improve user's 3D man-machine interaction and experience.And, during this 3D grating is put, the 2nd ITO conductive glass layer 330 that is used to form liquid crystal cell is used for preparing formation double-face electrode simultaneously, dexterously ITO electrode 331 and double-face electrode 340 are formed on same ITO conductive glass layer 330 two sides, realized the integrated combination of 3D grating and 3D gesture interaction device, integrated degree is high, simple in structure, thickness is little, preparation cost is low.
Figure 5 shows that the structural representation of another embodiment of the 3D interaction-electrode of the 3D grating using in display device embodiment illustrated in fig. 2; Figure 6 shows that the B-B cross section structure schematic diagram of the interaction-electrode of 3D shown in Fig. 5.Shown in Fig. 1, Fig. 5 and Fig. 6, in this embodiment, the one ITO conductive glass layer 310, liquid crystal layer 320, the formed liquid crystal cell of the 2nd ITO conductive glass layer 330 can be controlled by ITO electrode 311,331 biased electrical signals of ITO electrode, thereby can control liquid crystal cell and whether form liquid crystal parallax barrier or liquid crystal lenticular sheet, and then can realize the switching that 2D shows and 3D shows.For make this display device 30 there is 2D human-computer interaction function when 2D shows simultaneously, than Fig. 3 and embodiment illustrated in fig. 4, its also in the one side that is opposite in layer of polarizer 390 of the 2nd ITO conductive glass layer 330 simultaneously composition be provided for forming the ITO electrode 345 of capacitance touch screen electrode.Referring to Fig. 5 and Fig. 6, in this embodiment, 3D interaction-electrode only comprises that correspondence is arranged on the electric field receiving layer 341 of the 2nd ITO conductive glass layer 330 edge surrounding, reserve like this region that electric field receiving layer 341 surrounds, being used for composition forms ITO electrode 345, therefore, the generally corresponding middle section part that is arranged on the 2nd ITO conductive glass layer 330 of ITO electrode 345.ITO electrode 345 is used to form the electrode layer of capacitance touch screen, the concrete structure of ITO electrode 345 and pattern setting, according to specific implementation principle and concrete needs, carry out corresponding specific design, for example, ITO electrode 345 can be used for forming self-capacitance touch screen, also can be used for forming mutual capacitance touchscreens.The concrete structure setting of ITO electrode 345 is can application reference Ren Wei FocalTech Systems Co., Ltd. that apply on April 20th, 2010, name is called the ITO electrode of describing in patent " self-capacitance touch screen and coordinate data processing method thereof that one-dimensional electrodes is set ", that Chinese Patent Application No. is 201010170919.7, and the whole content of this application (201010170919.7) is included in this with way of reference.By electrode pattern design and electrode control design cleverly, can be so that 3D interaction-electrode 340 can also integrated capacitance touch screen electrode.
Like this, when ITO electrode 311, the corresponding electric signal of ITO electrode 331 biasing make it have 3D Presentation Function, the electric field transmitted layer of 3D interaction-electrode and the electric field receiving layer corresponding electric signal of setovering, so that it has 3D gesture interaction, control function, thereby can realize easily the man-machine interaction of 3D gesture.When ITO electrode 311, the corresponding electric signal of ITO electrode 331 biasing make it have 2D Presentation Function, the electric field transmitted layer of 3D interaction-electrode and electric field receiving layer be biased electrical signal not, ITO electrode 345 biasing corresponding electric signal are so that display device band touch controllable function, thereby can realize easily the man-machine interaction of touch control manner.Therefore, the demonstration that not only realizes 2D/3D is switched, and can between the control of 3D gesture interaction and the mutual control of 2D touch-control, carry out corresponding switching, greatly improves user and experiences.Certainly, which kind of mode man-machine interaction when in fact 3D gesture interaction also can show for 2D, otherwise man-machine interaction when 2D touch-control also can show for 3D, specifically select, and can or use developer select to determine by user.
Continue as shown in Figure 2, in this display device, two dimensional image display module 100 can be TFT-LCD display, these displays self are with layer of polarizer, therefore, layer of polarizer in this two dimension display module 100 is simultaneously as the lower layer of polarizer of parallax barrier in the stereoscopic display device shown in Fig. 2, and integrating device 30 does not need lower layer of polarizer.In other embodiments, when two dimensional image display module 100 is not when with the display of layer of polarizer, for example, plasma display, OLED(Organic Light-Emitting Diode, Organic Light Emitting Diode) display, can also between two dimensional image display module 100 and an ITO conductive glass layer 310, a layer of polarizer be set, this layer of polarizer is as the lower layer of polarizer of 3D grating.
Above example has mainly illustrated 3D grating of the present utility model and the display device that comprises this 3D grating.Although only some of them embodiment of the present utility model is described, those of ordinary skills should understand, and the utility model can be within not departing from its purport and scope be implemented with many other forms.Therefore, the example of showing and embodiment are regarded as illustrative and not restrictive, and in the situation that not departing from the utility model spirit as defined in appended each claim and scope, the utility model may be contained various modifications and replacement.
