The use to e of tetrafluoropropenes, particularly in a variety of applications, including refrigeration equipment, is disclosed. The circuit blocks CB1 to CBN include a logic circuit block LB, a grayscale voltage generation circuit block GB, data driver blocks DB1 to DB4, and a power supply circuit block PB. Based on a threshold logical segmentation size determined by the network protocol, each packet buffer is partitioned into a plurality of segments, each having an ending point linked to an Early ReceiveTransmit interrupt signal with the ending point of the packet buffer being linked to an OK interrupt signal. Alternatively, the frame capture rate is varied based on comparative image processing of a plurality of frames. A shared row selection circuit is provided between the first and second memory blocks, selectively or simultaneously selecting the first and second memory blocks, and transferring wordline voltages to a selected memory block by means in a multi-boosting manner.
