Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Figure 1, the present embodiment provides a kind of Foldable LED display screen, comprises one or more LED modules, and each LED module comprises some groups of LED light emitting diodes 102 and a flexible carrier 101.
In process of production, different according to the material of LED wafer, can to make different colours LED light emitting diodes, 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 light-splitting color-separating machine of each LED light emitting diode of same color is carried out to stepping, can obtain the LED light emitting diode of different class of all kinds.
For example, within forming arbitrary LED module of this example LED display, each LED light emitting diode is the LED light emitting diode that adopts light-splitting color-separating machine to obtain, and, LED light emitting diode of all kinds is the LED light emitting diode of same minute gear selecting,, all red LED light emitting diodes only adopt the LED light emitting diode of a minute gear selecting, all green LED light emitting diodes only adopt the LED light emitting diode of a minute gear selecting, and all blue led light emitting diodes also only adopt the LED light emitting diode of a minute gear selecting.
Because LED light emitting diode of all kinds adopts respectively identical minute gear selecting, 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, can think the consistent wavelength of all LED light emitting diodes in wavelength coverage.
And each arrangement mode of organizing LED light emitting diode is identical, meanwhile, the distance that each can also be organized between LED light emitting diode is made as equal; For example, in each group LED light emitting diode 102,1 red LED light emitting diode, 1 green LED light emitting diode and 1 blue led light emitting diode are all set, and, each LED light emitting diode is triangular in shape arranging all, and, the distance between each group LED light emitting diode is made as equal; Or, in each group LED light emitting diode 102,2 red LED light emitting diodes, 1 green LED light emitting diode and 1 blue led light emitting diode are all set, and, each LED light emitting diode is all quadrilateral arranges, and, the distance between each group LED light emitting diode is made as equal.
Due to, the color of each LED light emitting diode combined in each group LED light emitting diode,, the quantity of combination and the shape of arranging are all identical, and each is organized distance between LED light emitting diode and is made as equally, respectively organizes LED light emitting diode and is dot matrix and arranges; So, the LED display of composition is regular LED display, meets the requirement that arranges of conventional LED display, meets control and the display mode of prior art, and it is even that each organizes LED light-emitting diode arrangement, shows homogeneous, and display effect is good.
Wherein, described brightness refers to the bright-dark degree of LED light emitting diode, described color refers to three primary colours, red, green and blue, described wavelength refers to the emission wavelength of LED light emitting diode, described encapsulation comprises pinned encapsulation, surface-mount type encapsulation, power formula encapsulation etc., and described shape comprises round LED lamp, oval LED lamp, cylinder LED lamp, square LED lamp, Surface Mount LED lamp, LED lamp shaped like piranha etc.

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.
Or, similar with upper 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 only LED light emitting diode of an 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 minute gear selecting, or A+1 divide the LED light emitting diode of gear selecting.Like this, can dwindle the difference of LED accurate module inside.
That is to say, a good example is, when the same minimum of a certain color divides the LED light emitting diode quantity of gear selecting A enough, for this color LED light emitting diode of one or more LED accurate modules, only gets the LED light emitting diode of this minute gear selecting A; 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 minute gear selecting A-1, or, can choose the LED light emitting diode of minute gear selecting A+1, or, can also choose the LED light emitting diode of minute gear selecting A-1 and the LED light emitting diode of minute gear selecting A+1.
