Also add the text background collor as the collor of the screen.

assuming you mean an LCD screen, a couple of possibilities come to mind:

  • draw a rectangle (using background color) over the old text
  • write a couple of spaces over the old text
  • rewrite the previous text with background color first

Thanks
