I recently dropped my Droid X about 18" face-down onto a tiled floor. Although everything works fine, I have an odd result on the screen:

After picking the DX up, there was a 'splotch' or 'blot' in the middle of the screen; that seemed to be made up of pixels.
Over the next 3 days, this blot slowly unraveled itself, split into 3 separate lines and migrated to the lower right-hand side of the screen (see image).

Since the lines don't show up in a screenshot (and are superimposed over all graphics), I am unsure if this is damage to the LCD, or to the touchscreen.
Does anyone have any experience with this type of issue...any solid advice to offer?

Thanks, in advance!
