Hello element 14 people, I am here to ask you a question regarding LCD displays. I am currently trying to replace the back-light with UV LEDs in an attempt to build a miniature SLA 3D printer like the kick-starter project iBox nano. What I am having trouble with is figuring out how to run the LEDs properly. I could leave them on continuously and have them powered by a generic power supply rather than the LCD, but having the ability to control the LEDs will be very useful if not a necessity. I probably could just replace the back-light LEDs with the UV ones but they are the wrong sizes and I need them to be much more powerful. Is there a way I could use the back-light as a signal to activate a separate circuit for the UV LEDs, or a way I could amplify the power from the back-light so as to run the UV LEDs properly? I'd give you specifics on the voltages and currents involved here but I don't yet have the LEDs or display (display is a generic 3.5" composite input unit). I'm more curious if this is possible to do relatively simply, or whether or not it could be too complicated or destroy my LCD (and hopes and dreams).
Thank you.
