  • Publication number: 20240153896
    Abstract: A first protective layer is formed on a first die and a second die, and openings are formed within the first protective layer. The first die and the second die are encapsulated such that the encapsulant is thicker than the first die and the second die, and vias are formed within the openings. A redistribution layer can also be formed to extend over the encapsulant, and the first die may be separated from the second die.

  • Publication number: 20120178290
    Abstract: A waterproof solar power cable connector includes a first connection member, a clamping member, a waterproof member and a second connection member. The first connection member includes two open ends and a tapered inner periphery. The clamping member is received in the first connection member and has a ring from which multiple resilient pieces extend. The waterproof member is inserted into the first connection member and clamped by the resilient pieces of the clamping member. The ring of the clamping member is matched with the engaging portion of the waterproof member. The second connection member is connected to the first connection member. The second connection member has a contact surface which is matched with the engaging portion of the waterproof member so as to seal the connection between the inner periphery of the first connection member and the waterproof member to prevent from watering entering to damage the cable.

  • Patent number: 8159441
    Abstract: A driving apparatus suitable for driving a display panel which includes a plurality of gate lines is provided. The driving apparatus includes a driving unit and a voltage detecting unit. The driving unit is used to generate a plurality of output signals, so as to drive the gate lines with the output signals. The voltage detecting unit is electrically connected to the driving unit and generates a control signal according to the level of a logic driving voltage of the driving unit. The voltage detecting unit outputs the control signal to the driving unit, such that the driving unit generates the plurality of output signals simultaneously according to the control signal.

  • Patent number: 7839398
    Abstract: A gate driving circuit and a power control circuit are disclosed. The gate driving circuit includes a gate driver and the power control circuit. The gate driver is adapted for receiving a starting signal and sequentially outputting a plurality of scan signals accordingly. The power control circuit includes a delay circuit, a level shifter and a switch unit. The delay circuit is adapted for receiving and delaying the starting signal for a predetermined period and then outputting the delayed starting signal. The level shifter receives and adjusts a voltage level of the delayed starting signal, and outputs a starting voltage accordingly. The switch unit provides the first power to the gate driver after being delayed for the predetermined period according to the starting voltage.
