In August, prices of LCD panels - not the televisions themselves, but the panels that manufacturers and suppliers deal in - went down over four percent for the first time since September of 2010.  September's prices were even lower.  They decreased 4.9 percent from the already low August prices. One big piece of the puzzle, according to analysts from iHS, is that demand has lowered significantly for LCD televisions.  It's particularly visible in Europe and the U.S. but suppliers are expecting the holiday season to give prices a boost again.
