Abstract: The present invention provides, in an active matrix liquid crystal display device of the type including non-linear elements, for the application of an ON pulse-width modulation signal by the data line driving circuit at the rearward end of each selected period, during which the voltage corresponding to the duty-cycle of the selected signal is applied to the liquid crystal layer. The result is accurate reproduction of gray-scale images in the display under conditions of high duty-cycle driving. Further, cross-talk between columns caused by the data signal is controlled by supplying a signal voltage which eliminates the residual charges in the liquid crystal layer at the end of each selected period.

Abstract: A ring encircles produce placed on a work table. Tie ribbon is fed by pressure rollers around the inner periphery of the ring to form a complete loop. A first gripper clamps and retains the free end of the ribbon against a second gripper. The pressure rollers operate in reverse retracting excess ribbon about the produce. A friction clutch, operative only for reverse ribbon feeding, allows for ribbon slippage as the ribbon tightens around the produce. Then the second gripper clamps the other end of the ribbon against a twister head and a twister mechanism rotates the clamped ends of the ribbon about a common axis twisting the ribbon ends together. Shearing edges sever the engaged ribbon from a ribbon supply during twisting. The grippers and twister mechanism are at ends of the concentric support rods and tubes, and the grippers in clamping move along the rotational axis of the twister mechanism.
