Abstract: A printed circuit board includes a substrate, a plurality of metal wires, and a solder mask layer. The substrate includes a first area and a second area. The second area surrounds and does not overlap the first area. The metal wires are disposed on the first area of the substrate. One end of one of two adjacent metal wires faces one end of the other one of the two adjacent metal wires. The solder mask layer is formed on the second area of the substrate. In the present invention, a short circuit or an open circuit between the two adjacent metal wires is directly formed during processes of manufacturing the printed circuit board, whereby a jumper is not required so as to reduce a layout area, and cost of a manual post-welding treatment can be reduced.

Abstract: The present invention discloses a method for reducing ripple noise on the image of a display. The steps of the method include: (a) providing a first potential signal to a backlight module by an inverter; (b) resetting the inverter; (c) providing a second potential signal to the backlight by the inverter, wherein the phase difference between the first potential signal and the second potential signal is 180 degrees; (d) resetting again the inverter; and (e) repeating the steps (a) to (d) Consequently, the ripple noise present on the display would be effectively reduced by the alteration of the bright areas and dark areas on the display panel in conjunction with the persistence of vision of the user's eyes.
