Question for Wavelength of Medium 32x32 RGB LED matrix panel

Post by bellzero5 »

Hi I want to but a Medium 32x32 RGB LED matrix panel
However I can't find the information of wavelength of this LED.

And using this, how can i modify the wavelength of the LED.
For example, if i need 632nm wavelength, can i modify the wavelength just by controlling with Arduino??

Thanks

It's functionally impossible to change the output spectrum of an LED after it's been packaged.

Technically you could decap it, remove the wiring and substrate, vacuum polish it, then cook it at about 1200C in a quartz chamber with appropriate dopants to change the aggregate bandgap potential of the material. It's not a normal DIY project though.
