got a question about turning pixels off on a screen. I can make a black image and show it full screen on my pc. Yet the screen looks black but the pixels aren't off. You can see the difference between an off screen and a black screen.
I am wordering if it would be possible to turn these pixels off via a program or is the best you can do: make them black?
I am looking for the delphi code to turn off the right half of my computer screen?
hope its clear!
thx
You can't turn off individual pixels, or parts of the screen. Either the screen is on or it's off.
This works a bit differently depending on what kind of screen it is, but nowadays LCD screens is the most common kind. An LCD screen has a backlight behind an LCD display; the backlight is always on, and shine through the LCD display when the crystals are transparent. Pixels are made black by making the crystals non-transparent, however they still let a fraction of the back light through. To make pixels completely black you would have to turn the backlight off, and you can only to that for the entire screen.
