A method and system determines a location of a conversion device for converting wind energy into electrical energy by considering both technical and economic viability factors. The at least two processing units are connected via a real-time-capable data transmission path for transferring the first data. This 3D grid further includes: static grid lines which do not change while the system routes the connections; and dynamic grid lines which are created for routing a connection that includes pins which are not located on a static grid line. At least one optical film is disposed between the display panel and the light guide plate.
