    摘要: A polarity-reversible dimming controller having function of switching light source has a power supply module and a dimming control module. The dimming control module receives an external PWM dimming signal to control a feedback signal of the power supply module so as to dim or power on/off an LED lamp. The dimming control module has an output current switching circuit, a switch control circuit and a dimming control circuit. The output current switching circuit performs a PWM control over a current outputted from the power supply module by using the external PWM dimming signal to maintain chromacity of the LED lamp as a constant. The switch control circuit turns off the PWM controller to enter a standby mode for saving power once the PWM dimming signal exceeds a threshold value. As a full-wave rectification is performed on the PWM dimming signal, the polarity match issue upon assembling can be disregarded.

    摘要: A two-stage balancer for a multi-lamp backlight is electrically connected to a driving unit through a driving transformer. The two-stage balancer includes a plurality of first balancing transformers, second balancing transformers, and lighting units. Each of the first balancing transformers is electrically connected to the corresponding second balancing transformers to form a two-stage structure. In addition, a primary winding and a secondary winding of the second balancing transformer is electrically connected in series to one lighting unit, respectively, to form a circuit loop. Further, each of the circuit loops is electrically connected in parallel. Whereby the two-stage balancer provides much better current balance between the parallel circuit loops, and outputs a sinusoid-like driving current to increase lighting efficacy and further maintain uniform brightness of the multi-lamp backlight.

    摘要: The present invention provides an electronic packaging process. The surface of the chip carrier includes at least a chip attachment region and a film attachment region adjacent to the chip attachment region. At least a baffle is formed on the surface of the chip carrier, between the chip attachment region and the film attachment region. After attaching the thin film to the film attachment region of the chip carrier through an affixture layer, the chip is electrically and physically connected to the chip attachment region of the chip carrier through an adhesive layer. The baffle can effectively prevent the gas that is released from the adhesive layer from damaging the bonding between the thin film and the affixture layer. Therefore, almost no bubbles are formed and good electrical connection between the thin film and the affixture layer is maintained.
