摘要:
A method of forming a protection layer of a plasma display panel, which has upper electrodes, lower electrodes and a barrier rib, includes the steps of: forming a dielectric layer on the upper electrodes; and forming a MgO protection layer on the dielectric layer by the method of direct coating the MgO solution on the surface of the dielectric layer. Some advantages are derived by properly mixing MgO particles, salt containing Mg, and organic binder and coating an MgO protection layer (thin film) on the surface of the PDP substrate irrespective of coating methods by simple facility and processing. These advantages include PDP MgO protection layer formation to reduce PDP production cost, time and firing voltages, and adjustment of the protection layer's thickness.

摘要:
Thermally radiating heat sinks are soldered directly beneath individual LEDs and other heat generating electronic components on the opposite side of an FR4 circuit board and thermally coupled to the heat source through multiple micro-vias. The micro-vias are filled with solder in order to increase the thermal transmission of heat energy through the circuit board to the heat sinks The circuit board thickness is minimized to further reduce the thermal resistance of the transmission path. The method employed facilitates the heat transfer away from high-powered LEDs and other heat generating circuitry without spreading the heat energy to thermally sensitive electronic circuits and without the need for expensive substrates commonly employed to dissipate heat in electronic circuits. The method is adapted for LED lighting circuits and preferably to industry standard bulb sizes such as MR11, MR16, R20, PAR30, PAR38, and PAR56.

A device for transferring a film is provided. The device includes a roller transferring a film; a balancing unit connected to the roller by fixed supporters, the fixed supporters being disposed on both sides of the roller; and springs disposed on both sides of the balancing unit, wherein, if the film is out of balance, the balancing unit restores balance to the film by vibrating the both sides of the balancing unit. That is, if a film becomes out of balance during the transfer of the film, the device may restore balance to the film with the aid of the balancing unit which can vibrate on both sides of the balancing unit due to the springs.
