A method and a system are disclosed that enable an address at the edge router to be used to establish a multi-pipe virtual private network connecting controllers to multiple web enabled end user devices inside a security protected local area network. The organic light emitting diode display device includes a first flexible substrate, a second flexible substrate, a first barrier layer, a second barrier layer, an organic light emitting diode element, and a metal enclosing wall. The central guide mechanism includes a carriage and sliding rails. The gray scale control device may be coupled to the output electrode of the switching device to control a time interval during which the corresponding data signal is applied to the MEMS.
