Abstract: Provided are a hybrid-type mask stick and a mask frame assembly adopting the same. The mask frame assembly includes a mask frame; and a mask stick including a first mask stick extending in a first direction, a second mask stick extending in a second direction crossing the first direction, and a plurality of third mask sticks connected to the first mask stick and the second mask stick, the at least one first mask stick, the at least one second mask stick and the plurality of third mask sticks defining a plurality of deposition areas, wherein the first mask stick includes a first stick and a second stick arranged on the first stick, and at least one of the first stick and the second stick includes a partially-recessed portion in which the first mask stick is connected to the second mask stick.

Abstract: A hybrid mask stick and a mask frame assembly employing the same are provided. The mask frame assembly includes: a mask frame; and a mask stick assembly including a first mask stick that extends in a first direction, a second mask stick that extends in a second direction intersecting the first direction, and a plurality of third mask sticks that is coupled to ends of the first mask stick and the second mask stick and defines a plurality of deposition areas, wherein a thickness of the first mask stick is different from a thickness of the second mask stick, and a partial etching portion is arranged in a portion where the first mask stick and the second mask stick are coupled to each other.

Abstract: A method for testing a rotor blade of a wind turbine may include predefining a setpoint bending moment distribution. At least two active load-introducing means may be provided which each engage on a load frame. A first of the at least two active load-introducing means may be configured for introducing load in a pivot direction of the rotor blade and a second of the at least two active load-introducing means may be configured for introducing load in an impact direction of the rotor blade. Also provided is at least one passive load-introducing means. A cyclic introduction of load is effected by the at least two active load-introducing means, where a load introduction frequency of the first active load-introducing means and a load introduction frequency of the second active load-introducing means are selected such that the ratio thereof is rational. A testing device for carrying out the method is also provided.
