A mobile wastewater separator and recover unit and method for the separation and disposalrecovery of waste water for example in the oil and gas industry. A GPU program, that can be loaded and executed by a GPU, is obtained and encrypted to create an encrypted GPU program. The optoelectronic device may further include a doped cladding layer located over the active and passive devices and a barrier layer located over the doped cladding layer and the passive device. The active-matrix substrate further includes pixel electrodes connected with the gate lines and source lines, and gate line driving units provided in the display region for switching the gate lines to the selected or non-selected state in response to a supplied control signal.
