• controlling a roller arrangement, the roller arrangement comprising a first plate which is connected to a robot assembly for manipulating the roller arrangement;
• a second plate;
• at least one roller which is supported by the second plate, the roller being arranged to rotate in use about a roller axis;
• and, at least one resilient member arranged between the first plate and the second plate to connect the first plate and the second plate to each other such that the first plate and the second plate are spaced from each other, whereby the resilient member can absorb a shock or excessive force applied to at least one of the first plate and the second plate;
• the controlling the roller arrangement comprising:
• positioning the roller over the edge of a display screen which is laid on a backing frame;
• bringing the roller into contact with the edge of the display screen;
• and
• moving the roller arrangement along the edge of the display screen to cause the roller to apply a force to the edge of the display screen during assembly of the display screen to the backing frame.
