All manufacturers use 6-bit displays on most if not all portable models. In fact, the trend has been more use of 6-bit panels, because they can be made larger for cheaper with a lower response time, things which more consumers notice. Last I checked, LG (one of the biggest suppliers) didn't even make 8-bit panels anymore.
