A display device for displaying an event and method for monitoring and displaying a time interval related to a non-displayed past event andor a non-displayed future event. A phase measuring device includes a buffer delay measuring circuit and a phase difference measuring circuit which use a TDC, respectively, and a phase difference calculator. The leadframe strip is then treated with a surface preparation. The altered transmission rate improves the transmitter’s use of the available bandwidth to maintain an acceptable QoS at the receiver. As a result, the first transistor can discharge both negative and positive ESC events through parasitic bipolar conduction, without any additional circuits such as diodes used either to stop leakage currents or to conduct ESD current. The method includes recording a received digital data stream of data packet units by grouping the data packet units into an object, and creating and recording a managing information for the object.
