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 arc surface LED display screen, and the present embodiment arc surface LED display screen can be made up of one or more arc surface LED modules, and wherein, each arc surface LED module comprises an arc surface panel 104 and some LED unit 101.
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.
For example, in arbitrary arc surface LED module of forming this example arc surface LED display screen, arbitrary LED unit 101 comprises one or more LED light emitting diodes, each LED light emitting diode is the LED light emitting diode that adopts the beam split color scanner to obtain, and, LED light emitting diode of all kinds is the LED light emitting diode of same minute gear selecting, promptly, in the same arc surface LED module, 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.
