The invention relates to a method of supporting communication between a first network node and a second network node of a communications network, to the communications network, to the first and second network nodes, and to a switch controller for the second network node for carrying out the method. A power supply, a ground line, and a light emitting diode are electrically coupled to the TFT and an auxiliary electrode is electrically coupled to the ground line and to the source electrode of the driver transistor. The invention also relates to a method for displaying fuel consumption, characterized in that the excess fuel consumption caused by an electric consumer on board the motor vehicle is displayed in a separate manner. The die electrical contact and bonding ring can be bonded substantially simultaneously, with conductive bonding material, to the corresponding substrate electrical contact and a surface of said substrate, respectively, to thereby form a sensor. With the use of the conductive layer covering the semiconductor integrated circuit, electrostatic breakdown due to electrostatic discharge of the semiconductor integrated circuit can be prevented.
