Hi Alonzo,
To clean the dust inside the screen, you will have to disassemble the LCD panel. It is a very risky job and there is every chance of damaging the LCD screen unless you have a real good experience of doing it. If you are not good at doing such jobs, please let some professional do it for you.
You can use compressed air but it will leave the dust inside. If you remove the bezel you can take the front face off and clean it that way. I would not recommend using cleaning solvents to clean the screen use a dry cloth. The screws are on the back side along the edge of screen.
my new lg optimus one p500 is having a dust inside the screen.. within

The most severe problem dust can cause in an LCD TV is a short circuit. This occurs when dust enters the television's casing and settles on one or more of the internal circuit boards. Enough dust can cause a short circuit, which will prevent the TV from working at all. In other cases, it will damage picture quality or prevent certain features from working properly.
Because a short circuit can only occur when enough dust is present inside the TV, this problem happens after the TV has been in use for a number of years, meaning that it will not be covered under the manufacturer's warranty. In many cases of short circuits, repair is expensive, and you are better off buying a new set.
Image Quality
Dust can also have an effect on an LCD TV's picture quality without entering the LCD's casing. Dust that settles on the surface can distort the picture and decrease its brightness. While it's easy to wipe the dust away, use only a soft cloth and mild cleaning solution to avoid scratching the screen or causing permanent damage with caustic cleansers.
Dust under the screen can be more difficult to clean. Using compressed air to blow the dust out is the best option, short of disassembling the set to clean the screen from the inside. Keeping the surface of the screen free of dust is usually sufficient to prevent dust from getting under the screen.
Control Problems
Another effect dust can have on a an LCD TV occurs when it enters the space around buttons, making it difficult to control the television. On certain sets, dust will cause buttons to stick or prevent them from engaging when pressed. Using compressed air to blow the dust out, or resorting to using only the remote control, will solve this problem.
The spots can be in the inside of the lens settings to the CCD/imager.
If the cleaning of the lens is done well it can be a speck of dust logged in to the screen and having it on the image.
A careful cleaning in a dust proof set up is required.
Dust inside the LCD is rare...and not user removable. If it's between the actual LCD and a transparent cover, a good computer shop should be able to disassemble the screen and clean it for you. Don't try this yourself unless you are ready to buy a replacement screen. they are very fragile and easily damaged by probing fingers and screwdrivers.
You won't be able to get it cleaned with canned air. The dust that developed is underneath the screen. I recommend sending it to Nikon or the camera doctor.
Well, I pretty much knew that the display would have to be disassembled to clean the dust out. I should have been more specific by asking if the display "could" be taken apart to clean it out, especially since the dust is in between the image and light source layers.
