    摘要: Provided is a method for driving an electroluminescence display panel in which data electrode lines and scan electrode lines cross each other with predetermined gaps to form electroluminescence cells in the crossing areas. The method includes performing a preliminary charging stage in which the signal input terminals of the data electrode lines are switched and electrically disconnected from a data driving unit, and the other terminals of the data electrode lines are switched and electrically connected to one another in the initial stage of each parallel driving period. The preliminary charging stage is performed in the following parallel driving period when the data of the present parallel driving period and the data of the following parallel driving period are different.

    摘要: The top peaks of the outer fin are coated with slime-like flux. A sandwich unit is assembled from the outer fin and the tube plates by attaching the tube plates to the respective sides of the outer fin such that the surfaces of the tube plates having the butt bead faces formed thereon face inward. The butt bead faces on the respective tube plates on either side of the sandwich unit are coated with the slime-like flux. A plurality of sandwich units whose tube plates are coated with the flux are laminated and brazed, and the thus-formed assembly is heated in a heating furnace, to thereby braze together the tube plate pairs and the tube plates connected to the outer fin.

    摘要: A liquid crystal display device is provided which is capable of realizing high-quality display screen with low power consumption. A charge equilibration control signal VCST is outputted by a control unit (for example, driving timing generating section) for charge equilibration time in accordance with a video signal. At time of change in polarities of common voltages vCOM1 and vCOM2, a charge equilibration unit causes a shorting of a circuit between common electrodes COM1 and COM2 in accordance with the charge equilibration control signal so that a charge equilibration occurs between the common electrodes COM1 and COM2. The switching section turns off common voltages vCOM1 and vCOM respectively to the common electrodes COM1 and COM2. According to the charge equilibration control signal, the connection is turned on between the common electrodes COM1 and COM2.
