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 modules and a fixing body, and for example, fixing body is a casing, and described LED display device comprises led module 103, led module 104 and casing 101.
One or more LED unit 102 is set respectively on led module 103 and the led module 104, and each LED unit 102 is provided with versicolor one or a plurality of LED light emitting diode; Each LED light emitting diode can be a kind of color in red LED light emitting diode, green LED light emitting diode and the blue led light emitting diode or the LED light emitting diode of two kinds of colors or three kinds of colors arbitrarily.
In described led module 103 or the described led module 104, each LED unit is provided with the identical LED light emitting diode of all kinds of quantity, and in each LED unit, the arrangement mode of LED light emitting diode of all kinds is identical.
For example, 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, adopt the beam split color scanner to carry out stepping each LED light emitting diode of same color, promptly can obtain the LED light emitting diode of different class of all kinds.
And for example, in each LED unit 102, the LED light emitting diode that each color is identical is the LED light emitting diode that adopts the same minute gear selecting that the beam split color scanner obtains, be in the described LED unit, 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; For example, select A to divide the LED light emitting diode of gear selecting.
Perhaps, in led module 103 or led module 104, each LED light emitting diode of same color is the LED light emitting diode of same minute gear selecting and adjacent minute gear selecting thereof.
For example, described led module 103 is provided with LED unit X and LED unit Y, and LED unit X comprises one or more LED light emitting diodes, and LED unit Y comprises one or more LED light emitting diodes; And LED unit X and LED unit Y comprise the quantity of LED light emitting diode, and be all identical with the color of combination; As, LED unit X comprise 1 red LED light emitting diode, 1 green LED light emitting diode and 1 blue led light emitting diode and, LED unit Y also comprises 1 red LED light emitting diode, 1 green LED light emitting diode and 1 blue led light emitting diode; And the LED light emitting diode that each color is identical is the LED light emitting diode that adopts the same minute gear selecting that the beam split color scanner obtains.
Because each LED light emitting diode that each color is identical 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 the color that each LED light emitting diode people's in a certain wavelength coverage naked eyes are seen is identical, promptly can think the consistent wavelength of all the LED light emitting diodes in wavelength coverage.
