Abstract: A display device includes a display panel, a circuit board, and a conductive element. The circuit board is adjacent to the display panel and electrically connected to the display panel. The circuit board has at least a conductive pattern configured at a ground zone, and the conductive pattern has a plurality of conductive portions spaced apart each other. The quantities of the conductive portions respectively arranged along a first direction and a second direction are plural, and the first direction is substantially perpendicular to the second direction. The conductive element is disposed on the conductive pattern, and the conductive element is electrically connected to the conductive portions.

Abstract: A liquid crystal display (LCD) and an overdrive method of an LCD, which benefits multi-frame polarity inversion technology, are provided. A timing controller of an LCD receives a video and provides the following operations. In a case wherein a multi-frame polarity inversion manner is used, if a current frame that is processed to be displayed on the screen requires polarity inversion, the timing controller performs an overdrive procedure in accordance with a first overdrive rule, and, if the current frame does not require polarity inversion, the timing controller performs the overdrive procedure in accordance with a second overdrive rule different from the first overdrive rule.

Abstract: A telephone adapter (10) connected between a local telephone set (20) and a network (30) includes a processor (130), a subscriber line interface circuit (SLIC) (100) and plural indicating groups (152, 154, 156). The indicating groups connected to the processor, indicate status of the local telephone set. When detecting status of the local telephone set, the SLIC sends status signals to the processor. The processor generates first control signals according to the status signals, and sends the first control signals to the indicating groups. When receiving communication signals from the network, the processor processes the signals, and generates first and second control signals. The processor sends the second control signals to the local telephone set via the SLIC to make the local telephone set act correspondingly. The processor sends the first control signals to the indicating groups to drive the indicating groups to indicate the status of the local telephone set.
