I took a photo of my monitor (108ppi) with my phone Xiaomi Mi note 10 and those are white pixels.
The image is cropped so it can fit the 5MB limit.
You can see that the subpixels (red green and blue) are each composed of around 140 dots that i assume are the liquid crystals?
So each subpixel is composed by 140 liquid crystals?
I couldn't find anything online so if you got a clue please comment
