How to turn off the LCD screen of the nikon 3000?

I purchased a D3000 because I liked nikon image quality & was taken by its striking exposure control. Sadly, I have come to think of it as a dog for number of reasons. Most frustrating is not being able to turn the LCD screen off. It makes the cameraman but useless at night or in low light, because off the dazzle of the LCD. ANY IDEAS BEYOND DUCT TAPE?

I don't know.
