Abstract: The invention discloses a transformer for a backlight apparatus including a lamp and a detecting unit. The transformer includes a bobbin, a first winding and a second winding. The bobbin has a low-voltage winding region and a high-voltage winding region. The first winding is wound on the high-voltage winding region and is coupled to the lamp. The low-voltage winding region has a first pin, a second pin and a third pin. Firstly, the second winding is wound on the first pin and then wound on the low-voltage winding region for M turns. Next, the second winding is drawn out from the low-voltage winding region, then wound on the second pin, and then drawn back to be wound on the low-voltage winding region for N turns again. Afterwards, the second winding is drawn out again and wound on the third pin, where each of M and N is a nature number. In addition, the third pin is coupled to the detecting unit.

Abstract: The disclosed is a silica-polymeric resin composite of blending the silicon dioxide nanoparticles in thermoplastic polymer and method for manufacturing the same, thereby improving its scratch-resistance. A thermoplastic polymer is dissolved in solvent to form a thermoplastic polymer solution. The polymer solution is evenly mixed with a silicon dioxide sol, and the solvent is then removed to complete the silica-polymeric resin composite. In the silica-polymeric resin composite, the silicon dioxide nanoparticles and the thermoplastic polymer have no chemical bonding therebetween, and the silicon dioxide nanoparticles are evenly dispersed in the thermoplastic polymer.

Abstract: A thin key structure for generating dazzling light includes a thin film layer, a protective layer, a stripe layer, and a flexible layer.

Abstract: An inverter for driving multiple discharge lamps. The inverter has a transformer for driving a first discharge lamp and a second discharge lamp. The inverter also includes a first balancing circuit connected in series with the first discharge lamp and a second balancing circuit connected in series with the second discharge lamp. According to a matching signal, the first and the second balancing circuits adjust a first lamp current through the first discharge lamp and a second lamp current through the second discharge lamp, respectively. A comparator is provided to receive a first sensing signal from the first balancing circuit and a second sensing signal from the second balancing circuit. Comparing the first sensing signal with the second sensing signal, the comparator generates the matching signal which controls the first and the second balancing circuits to equalize the first lamp current and the second lamp current.
