Abstract: An electrical connector assembly includes a first and a second connectors to be mated together, and a Connector Position Assurance (CPA) device installed on one of the first and second connectors. The CPA device is fixed to a pre-lock position when shipped together with said one of the connectors and before the first and second connectors are mated. At the pre-lock position, a locking lever on the second connector can be deformed so that primary locking members of the first and second connectors can be engaged. When the first and second connectors are mated, a rib formed on the first connector acts on a release member provided on the CPA device, to allow the CPA device to move to a final lock position at which, a secondary locking member restricts the movement of the primary locking member of the second connector to prevent the primary locking members from being disengaged.

Abstract: A plasma display panel employs a voltage circuit having an input and an output, the voltage circuit configured for supplying a negative voltage for an electrode. The plasma display panel also employs a power supply that has a positive terminal and a negative terminal, where the negative terminal is connected to the input of the voltage circuit. The power supply is otherwise configured relative to the voltage circuit such that the voltage difference between the output and the input of the voltage circuit is fixed as a function of the power supply. By fixing this voltage difference, parasitic capacitance is minimized, power consumption and calorific value are reduced, and the plasma display panel operates in a more stable manner.

Abstract: A method of driving a plasma display panel wherein a selective inversion system is used to perform an address operation. In the method, a reset step makes an entire write discharge of the cells to form wall charges. An address step makes an address discharge of specific cells of the cells undergoing said entire write discharge to invert the polarities of the wall charges of said specific cells and to keep the polarities of the wall charges according to said entire write discharge as they are at the remaining cells excluding said specific cells. A sustain step makes a sustain discharge of only the specific cells having the inverted wall charge polarity by a sustain pulse. Accordingly, a data is written by the selective inversion addressing method to permit a high-speed driving and to prevent a contrast deterioration.
