Embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

Embodiment 1

As shown in Figure 1, present embodiment provides a kind of LED display device, and described LED display device comprises at least two LED accurate modules, a regulation and control unit and a mounting structure; As, comprise LED accurate module 101, LED accurate module 101a, regulation and control unit 103 and comprise fixed frame 104 and the mounting structure of fixed frame 104a.

In process of production, according to the material difference of LED wafer, can make the LED light emitting diode of different colours, the LED light emitting diode of different colours is produced respectively in batches, and, can adopt identical encapsulation, be made into identical shaped and big or small LED light emitting diode, the employing beam split color scanner of each LED light emitting diode of same color is carried out stepping, promptly can obtain the LED light emitting diode of different class of all kinds.

In LED accurate module 101, LED light emitting diode of all kinds is the LED light emitting diode of same minute gear selecting, promptly, all red LED light emitting diodes only adopt the LED light emitting diode of a branch gear selecting, all green LED light emitting diodes only adopt the LED light emitting diode of a branch gear selecting, and all blue led light emitting diodes also only adopt the LED light emitting diode of a branch gear selecting.

Because LED light emitting diode of all kinds adopts identical branch gear selecting respectively, therefore, the brightness of the LED light emitting diode of same color is identical, consistent wavelength, encapsulation is identical, shape is identical and big or small identical; Described consistent wavelength refers to, and each LED light emitting diode color that people's naked eyes are seen in a certain wavelength coverage is identical, promptly can think the consistent wavelength of all the LED light emitting diodes in wavelength coverage.

Perhaps, an example is, LED light emitting diode of all kinds can also be selected the LED light emitting diode of adjacent class, for example, select A to divide the LED light emitting diode of gear selecting, with and the LED light emitting diode of each one fen gear selecting of front and back, i.e. the LED light emitting diode of A ± 1 minute gear selecting, more particularly, be the LED light emitting diode of A-1 branch gear selecting and the LED light emitting diode of A+1 branch gear selecting.

Adjacent LED light emitting diode has identical encapsulation, identical shape and identical size equally, and, in very little error range, be in the scope of human eye for brightness and wavelength change perceived, the LED light emitting diode of adjacent class, its brightness can be thought identical approx, and it is consistent that wavelength also can be thought.

Perhaps, similar with last example, LED light emitting diode of all kinds is the LED light emitting diode of same minute gear selecting and one adjacent minute gear selecting thereof, that is to say, LED light emitting diode of all kinds can also be selected the LED light emitting diode of an only adjacent class, for example, select A to divide the LED light emitting diode of gear selecting, and, the LED light emitting diode of arbitrary minute gear selecting before and after it, be the LED light emitting diode of A-1 branch gear selecting, perhaps, A+1 divides the LED light emitting diode of gear selecting.Like this, can dwindle the difference of LED accurate module inside.

That is to say, one preferably example be when a certain color same minimum divides the LED light emitting diode quantity of gear selecting A enough,, only to get the LED light emitting diode of this minute gear selecting A for this color LED light emitting diode of one or more LED accurate modules; When the same minimum of a certain color is divided the LED light emitting diode lazy weight of gear selecting A, this color LED light emitting diode for one or more LED accurate modules, can choose the LED light emitting diode of branch gear selecting A-1, perhaps, can choose the LED light emitting diode of branch gear selecting A+1, perhaps, can also choose the LED light emitting diode of branch gear selecting A-1 and the LED light emitting diode of branch gear selecting A+1.
