Abstract: An electronic device is provided. The electronic device includes a first substrate; a second substrate disposed opposite to the first substrate; a liquid crystal layer disposed between the first substrate and the second substrate; a plurality of first electrodes disposed between the first substrate and the liquid crystal layer; a plurality of second electrodes disposed between the second substrate and the liquid crystal layer; a first signal line disposed between the first substrate and the liquid crystal layer, and electrically connected to one of the plurality of first electrodes; and a second signal line disposed between the second substrate and the liquid crystal layer, and electrically connected to one of the plurality of second electrodes. The first signal line and the second signal line include a blackened metal.

Abstract: A winding construction for a transformer includes a single frame transformer core, an insulator layer, a primary winding, and a secondary winding. The secondary winding is wound with turns wound in a tilted arrangement on the single frame transformer core, whereby it can exhibit the same effects as the conventional partition or layer type transformer but without the need for an additional partition layer and achieves enhanced performance and reduced volume.
