Abstract: An electronic device including a housing; a printed circuit board (PCB) in the housing, wherein the PCB includes a plurality of layers with one or more conductive and insulation layers; a first electrical component formed as at least a part of or in the housing; a second electrical component above or near the PCB in the housing, wherein the first and second electrical components are separated; and at least one electrical path extending from the first electrical component to the second electrical component, wherein at least a portion of the electrical path runs on or inside the PCB, wherein the PCB includes a region including a pattern of conductive vias, wherein each of the vias extends through at least part of the plurality of layers to contact at least one of the one or more conductive layers, and wherein the electrical path runs through the region without contacting the vias.

Abstract: The display device includes a driving circuit and a panel. The driving circuit is configured to generate a source output enable signal having at least one pulse during one horizontal scanning period in response to a mode signal and configured to generate a source driving signal by latching an image data in response to the source output enable signal. The driving circuit is further configured to generate an internal horizontal synchronization signal in response to the source output enable signal and configured to generate a gate driving signal in response to the internal horizontal synchronization signal. The panel is configured to display the image data in response to the gate driving signal and the source driving signal.

Abstract: An antenna ground structure of a mobile terminal is disclosed. The antenna ground structure of a mobile terminal is arranged to provide the ground pattern on a Printed Circuit Board (PCB) adjacent to the antenna and to electrically connect the ground pattern to the ground unit of the antenna, so that the area of the ground of the antenna may be expanded to improve Specific Absorption Rate (SAR) and communication performance.
