Why do computer screens project black when they can just project nothing?

If your monitor is off it projects nothing so why can’t they just project nothing for black?

In the old days, we also had plasma screens, which was an improvement on the CRT- instead of a beam scanning and illuminating each pixel, there was an electron gun for each pixel, so you got true black and really good viewing angle and contrast. The problem was that they were inefficient and subject to burn-in, so once LCDs got good enough they discontinued them. I have one of the last Panasonic plasma TV’s and even though it is only 1080p it’s still my favorite screen because it looks great. I’m watching AMOLED prices but they’re still to high for my taste.
