this may seem like a dumb question, but I've always wondered this.
How does a color TFT LCD display monochrome images?
from what I understand, a TFT display has 3 RGB subpixels which are artificially colored by filters.
each sub pixel is either on or off in such a way to display any of the millions of color combinations of Red Green and Blue.
When a pixel is open it allows light to pass through from backlamp. When closed it's totally dark or I guess, dark on one or more colors?
If all 3 are closed this is black. what is white?
Also how do the color filters work? If each pixel is a liquid crystal cell that either passes light, or does not, what type of filter is used to make the rgb? how do they make it so small?
