Designing a scientifically proper scanning backlight from scratch, for an existing LCD computer monitor, requires disassembling LCD’s. There is an LCD parts store page that has info useful during my research, including a YouTube video on how to disassemble LCD panels...

[This is a very old article from scanning backlight experiments in 2012] A 23″ LCD computer monitor is 286mm high x 508mm wide. From math calculations on LED ribbons (120 LED per meter, 6mm wide, 6500K, ~10watt/meter, 80+CRI available), one can put...

Found a pre-made Arduino-compatible MOSFET switch for $18 each. Four of these 4-channel switches will be suitable for a 16-segment Arduino scanning backlight. These can switch well over 100 watts per segment, and at frequencies up to 200,000Hz; fast and...

I have a breakthrough in a millisecond-accurate input lag tester, that is as almost as accurate as using as an oscilloscope and a photodiode. I am creating photographs on how you can construct your own inexpensive Arduino input lag meter....
