Three LED show the adjacent arrangement of subarray, and adopt the LED element of the different color in the three primary colours respectively, constitute a LED and show group of subarrays.At least two LED show that group of subarrays is arranged above and below, and formation can show the three-dimensional light-emitting diode display of various rich colors.External accessory is through controlling the situation of the lighting acquisition stereopsis that each LED shows each the LED element in the subarray respectively.
All right, LED shows that subarray is embedded in the LED substrate.Can adopt in the manufacturing when producing range upon range of LED display, the subarray that LED is shown that is adopted is embedded in the method in the said LED substrate, obtains LED and shows that subarray is embedded in the three-dimensional light-emitting diode display in the said LED substrate.The LED substrate peripheral can be cylindricality, sphere, polygon or other shapes.The electrode that connects the pin of LED element in the LED array of display can adopt transparency electrode, also can adopt tinsel, such as copper wire, filamentary silver etc.Tinsel should be thin in order to avoid influence vision.
With reference to Fig. 4, based on the aerial stereo imaging system of range upon range of LED display, comprise an air-borne imagery system, the air-borne imagery system comprises a picture light source, comprises that also one will form the photoimaging system of picture from the light as light source aloft.Adopt range upon range of LED display as light source.Preferred three-dimensional light-emitting diode display 7.The photoimaging system comprise one will converge from light as light source converge optical device 8; Three-dimensional light-emitting diode display 7 is combined closely with the surface of converging optical device 8; The stereopsis 71 that three-dimensional light-emitting diode display 7 produces is positioned at and converges optical device 8 determined imaging regions; With as as light source, stereopsis 71 is presented in the air.Through being combined closely in three-dimensional light-emitting diode display 7 and the surface of converging optical device 8, reduce light refraction and reflection, and then can improve image quality, also can avoid in addition between the device because the external force dislocation as far as possible.
Converge optical device 8 among Fig. 4 and adopt a concave surface to converge device, three-dimensional light-emitting diode display 7 is positioned at the concave surface that concave surface converges device.And it is corresponding that the peripheral structure of three-dimensional light-emitting diode display 7 and concave surface converge the device inside surface, and both combine closely.The viewing area of three-dimensional light-emitting diode display 7 is positioned at concave surface and converges near the device axis.So that form the aerial preferably space image of image quality.
In concrete the use, converge optical device 8 and can adopt two concave surfaces to converge device, two concave surfaces converge device and fasten relatively, and light-emitting diode display converges between the device at two said concave surfaces.Wherein at least one said concave surface converges the device bottom and is provided with the printing opacity mouth, so that beam projecting forms picture aloft.
Converge optical device 8 and can also adopt a plus lens, three-dimensional light-emitting diode display 7 is positioned at plus lens one side, and the plus lens Direct Production is on three-dimensional light-emitting diode display 7.So that form the aerial preferably space image of image quality.
The photoimaging system can also comprise that a cabinet and is positioned at the spectroscope group of cabinet top for an aerial imaging suspension system based on spectroscope imaging, and said light-emitting diode display is arranged in the said cabinet of said spectroscope group below, as the picture light source.
Existing aerial imaging suspension system based on spectroscope imaging generally is made up of cabinet, spectroscope group, shot-light, video playback apparatus; Based on the spectroscope image-forming principle; Through the product real scene shooting being made up the special processing of three-dimensional model; March into the arena the product image of taking or the stack of product three-dimensional model image in the scape then, constituted the product demonstration system of being association of activity and inertia.Finally show the product model phantom imaging effect that incorporates outdoor scene to spectators.
Among the present invention, can shot-light be omitted, change video playback apparatus into light-emitting diode display, and carry out suitable conventional optical system optimization, can realize effect.
More than show and describe ultimate principle of the present invention and principal character advantage of the present invention.The technician of the industry should understand the restriction that the present invention does not receive above-mentioned method of application; That describes in above-mentioned method of application and the instructions just says principle of the present invention; The present invention also has various changes and modifications under the prerequisite that does not break away from spirit and scope of the invention, and these variations and improvement all fall into and require the interior requirement protection domain of the present invention of the protection scope of the invention to be defined by appending claims and equivalent thereof.
