Abstract: One or more Wireless Access Points (WAPs) are provided for a transportation vehicle. One WAP includes a combined board having a first area with micro-processor components and a second area with antenna elements, the second area located at a periphery of the combined board; a metallic cover placed over the first area; and a non-metallic cover placed over the metallic cover and the second area.

Abstract: A display device capable of decreasing an amplifier offset using a gate-start pulse signal is disclosed. A display device includes a display panel, a control circuit, a gate driving circuit and a source driving circuit. The source driving circuit includes a plurality of source driving chips, compensates for an amplifier offset in response to the gate-start pulse signal, performs digital-to-analog (D/A) conversion on data received from the control circuit using gray scale voltages in response to the source control signal, and provides the converted data to the source lines.
