Draw or repulsive interaction, and the attraction or repulsive interaction of the second transparent conductive substrate 32 and transparent charged particle 21 cause oolemma
The electric movement of particulate 21 forms the different lenticule of focal length.
Above-mentioned display device 1 can use currently used display device 1, preferably above-mentioned display device 1 be selected from LCD,
LED, OLED, Micro LED, Micro OLED, projective module it is in the block any one.Have on above-mentioned all types of display devices 1
Micro- image primitive.
In order to make those skilled in the art more fully understand the application, below with reference to embodiment and attached drawing to display device
Illustrate.
As shown in fig. 7, there are alphabetical " A " and alphabetical " B " two images, wherein word on the 2D images shown on display device 1
The image primitive array in female " A " corresponding 1 upper left corner of display device；The image primitive battle array of alphabetical " B " corresponding 1 middle position of display device
Row, the image correspond to the depth of the depth less than alphabetical " B " of alphabetical " A " in real image.It is in addition, saturating in micro-cavity structure 11
Bright charged particle 21 is the silicon dioxide granule with positive charge, and transparent medium 22 is hydrocarbon solution, and transparent medium 22 is full of
The cavity of micro-cavity structure 11.Micro-cavity structure 11 is spherical microcavity structure 11, the first transparent conductive substrate 31, micro-cavity structure 11 and
Two transparent conductive substrates 32, which correspond, to be set.Display device 1 is LED display device 1.
303 memory of information comparison module contains the electric signal of corresponding alphabetical " A " depth and the telecommunications of corresponding alphabetical " B " depth
Number；Image information capture module 301 catches the 2D image informations shown in Fig. 7, and message processing module 302 is different according to picture depth
Image information is converted into electric signal, then information comparison module 303 by the electric signal of reception compared with standard electric signal,
Signal output module 304 sends following electrical instruction according to the comparative result of information comparison module 303：
The transparency electrode of the remote display device 1 of the micro-cavity structure 11 of corresponding letter " A " is cathode, close to display device 1
Transparency electrode no power；The transparency electrode of the close display device 1 of the micro-cavity structure 11 of corresponding letter " B " is cathode, remote
The transparency electrode no power of display device 1, it is remote based on what identical charges repel each other, as shown in figure 8, corresponding to the microcavity of letter " A " in I portions
Transparent charged particle 21 in structure 11 is moved to the direction close to display device 1, the micro-cavity structure of corresponding letter " B " in II portions
Transparent charged particle 21 in 11 is moved to the direction away from display device 1.
When the 2D images shown by display device 1 pass through the microlens array 2, as shown in figure 9, corresponding display pattern word
The light of female " A " is refracted out earlier；As shown in Figure 10, the light of corresponding character " B " is relatively late refracted out, and is formed
3D rendering it is as shown in figure 11, i.e. the different depth of display pattern alphabetical " A " and display pattern letter " B " is complete in the 3 d image
Display entirely, and wherein H is the distance between lenticule and 2D image primitives, under different conditions, lenticule and 2D image primitives
Distance is different, i.e., H is also different.L1For alphabetical " A " the Depth Imaging plan range of display pattern, L2It is deep for display pattern alphabetical " B "
Spend imaging plane distance.
It can be seen from the above description that the above embodiments of the present invention realize following technique effect：
Transparency electrode is set in each micro-cavity structure opposite both sides, by adjusting the transparency electrode of side and transparent powered micro-
The position of transparent charged particle in the identical revertive control difference micro-cavity structure with phase of the powered polarity of grain, and then it is applied to 3D
In display device as microlens array in use, due to transparent charged particle 21 under different voltage controls in microcavity body knot
The lens shape of formation, refractive index, position are different in structure 11, and cause the display of different lenticule Yu 3D display device
The distance H of 2D image primitives also can be different in equipment, can derive that Depth Imaging plan range L is according to Gauss imagingOn the premise of polarity of electrode and its size determine, focal length f and distance H is determine value, by above-mentioned public affairs
Formula understands Depth Imaging plan range L to determine value, and then L values are different under different polarity of electrode and size, therefore utilizes this
Shown 3D rendering is embodied except imaging depth changes after the microlens array processing of application so that shown 3D rendering is more
To be vivid, true to nature.Above-mentioned transparent medium is full of the cavity of micro-cavity structure.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this area
For art personnel, the invention may be variously modified and varied.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
