In a mother substrate for a lower substrate, a substrate for a display panel and a method of manufacturing a display panel, the substrate for the display panel includes a lower substrate and an upper substrate facing the lower substrate. The most-recently-used stack item appears at the top of the stack and the least-recently-used item is at the bottom of the stack. The network accommodates all such types of data and assigns data types to time slots or frame segments within each frame to ensure streaming data maintains its temporal relationship at the receiver consistent with the transmitter. The receiver receives an encoded signal from the data transmitter via the network, and displays the encoded signal on the video player, wherein the encoded signal has a f1irst operating mode. In turn, the baddie is contacted using number information of the victim’s phone and connected with the victim.
